sars-cov-2

COVID-19 is a disease that is caused by SARS-CoV-2 and very speedily spreading all over the world. The blood group’s effect on COVID-19 is not clear. The main aim of this article is to determine the relationship between sensitivity of COVID-19 and ABO blood group. For this study we have observed that the individuals with blood group A are at higher risk of getting COVID-19 because they contain the higher concentration of Angiotensin-converting enzyme-2 that provide the site to virus for entry. But in other blood groups the natural Anti A antibodies block the interaction between host receptor and virus and disturb their interaction. Certain studies show that the infectivity and mortality rate in covid patients is not affected by AB blood group system. But according to research, increased ventilator usage, ICU stay was observed in critically ill patients with AB blood group than of other blood groups. O blood group has proved to be protective against SARS-CoV-2 due to the presence of both anti-A and anti-B antibodies as they prevent the binding of the spike protein S of the virus with the ACE2 receptors which are present on the surface of cells. Moreover, furin also plays a major role in penetration of virus in the host cells. Furin is required for the activation of the spike protein S of the virus and due to the low efficiency of furin cleavage in blood group O it is protected from SARS-CoV-2 and other chronic diseases. Mortality rate of covid 19 depends upon the environmental factors, number of people living in the area and also some economic factors. The different strains of COVID-19 effect the different people differently and as the time passes the strain of COVID-19 has changed and thus according to this the mortality rate of different provinces and areas varies due to environmental factors. Pregnant women have no any kind of transportation of covid to their fetuses but mostly patients of blood group A are being affected by COVID-19 and hence their fetuses are somehow effected. And those pregnant women having blood group O does not have any risk of COVID-19 of severe stages.

SARS-CoV-2 a virulent disease that established the entire wide world due to its severity. Its 1st case was rumored in Wuhan, China within the year 2019 and it had been the beginning of this pandemic. This virus killed virtually a complete of 4,465,683 folks round the globe until date. Despite the fact that viral co-infections have the ability to alter the host’s illness pattern, few research have looked at the disease outcomes in patients who are infected with HIV and hCoVs. Despite the fact that HIV-positive people can be infected with hCoVs, researchers are now revealing that their chances of acquiring serious CoV-related disorders are typically similar to what is seen in the general population. The relation between SARS-CoV-2 and HBV was summarized rather HBV effects the severity of COVID patient or not. SARS-CoV-2 could be a severe acute metabolic process syndrome. Scientists found ways in which to treat this virus, some were useful and alternative weren’t that a lot of effective. Immunizing agent was one among the most important considerations for the entire world. This virus conjointly fashioned an entry for alternative co-infections too. SARS-CoV-2 and influenza virus, both causes respiratory diseases which confer as an extensive array of illness from asymptomatic or benign to critical disease and death. Also the mode of transmission and symptoms of influenza virus and SARS-CoV-2 are same. Viral and bacterial rate is higher in SARS-CoV-2 negative patient but are comparable. Serologies facts confirmed that patients with effective results for dengue virus (DENV) NS1 antigen and anti-dengue IgM were also attentive to COVID-19 speedy antibody tests, suggesting dengue COVID-19 co-infection. Mixed infection of dengue and COVID-19 needs unique interest from all dengue-common nations in Asia, especially the ones with limited resources. To our knowledge, this is the primary showed case of co-infection of dengue and COVID-19 in Indonesia. During patient’s TB course, COVID-19 can occur at any time with worse consequences for the patients who are affected by active pulmonary disease.

The lockdown, implemented in response to the COVID-19 epidemic, restricted the operation of various sectors in the country and its highlights a good environmental outcome. Thus, a comparison of air pollutants in India before and after the imposed lockdown indicated an overall improvement air quality across major Indian cities. This was established by utilizing the Central Pollution Control Board’s database of air quality monitoring station statistics, such as air quality patterns. During the COVID-19 epidemic, India’s pre-to-post nationwide lockdown was examined. The air quality data was collected from 30-12-2019 to 28-04-2020 and synthesized using 231 Automatic air quality monitoring stations in a major Indian metropolis. Specifically, air pollutant concentrations, temperature, and relative humidity variation during COVID-19 pandemic pre-to-post lockdown variation in India were monitored. As an outcome, several cities around the country have reported improved air quality. Generally, the air quality, on a categorical scale was found to be ‘Good’. However, a few cities from the North-eastern part of India were categorized as ‘Moderate/Satisfactory’. Overall, the particulate matters reduction was in around 60% and other gaseous pollutants was in 40% reduction was observed during the lockdown period. The results of this study include an analysis of air quality data derived from continuous air quality monitoring stations from the pre-lockdown to post-lockdown period. Air quality in India improved following the national lockdown, the interpretation of trends for PM 2.5, PM 10, SO2, NO2, and the Air Quality Index has been provided in studies for major cities across India, including Delhi, Gurugram, Noida, Mumbai, Kolkata, Bengaluru, Patna, and others.

Purpose: Real-time reverse-transcription polymerase chain reaction (RT-PCR)-based testing remains the gold standard for the diagnosis of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to the high diagnosis demand of SARS-CoV-2 and the limited resources for RT-PCR testing, especially in Low-Income Countries (LICs), antigen-based methods are being considered as an option. The aim of this study was to assess the performance of LumiraDx SARS-CoV-2 antigen assay for large population screening compared to RT-PCR.Methods: This evaluation was conducted on 4146 participants including travelers and participants under household survey and vaccine evaluation studies before injection of the first dose. Oropharyngeal and nasopharyngeal swaps were collected from each participant into 2 mL of viral transport medium (VTM) and 400 μl of VTM were used to assess the performance of LumiraDx SARS-CoV-2 antigen assay, compared to RT-PCR. Results: The prevalence of SARS-CoV-2 of the cohort was 4.5% with RT-PCR and 4.1% with LumiraDx antigen test. Compared to the RT-PCR, the sensitivity and specificity of the LumiraDx antigen SARS-CoV-2 test were 82,7% [95% CI 74.1-89,7] and 99.9% [95% CI 99.6-99.9] respectively. Given the RT-PCR threshold cycle (Ct) range, the sensitivity was 92.1% [95% CI 84.6-96.3] when the Ct value was below or equal 33 cycles, and 38.1% [95% CI 18.9-61.3] when it was above 33 cycles. The inter-rater reliability showed a kappa coefficient of 0.88 when considering all the patients and 0.94 for Ct values below 33 cycles. Conclusion: Our data have shown that the LumiraDx platform can be considered for large-scale testing of SARS-CoV-2.

Due to extensive COVID-19 prevention measures, millions of tons of chemicals penetrated the natural environment. Alterations of viruses in the environment, the neglected perceiver of environmental fluctuations, remain obscure. Chemicals especially trihalomethane restrained the virus community diversity. Segments of SARS-CoV-2 RNA have been detected near hospitals that suggesting the environment as a missing link in the transmission route. Human viruses lurking in the environment were potentially activated by pandemic prevention chemicals, warning an overlooked burden to human health. This letter warns of the risk of activation of human viruses in the environment following the overuse of COVID-19 prevention devices and emphasizes the long-term monitoring of environmental viruses in the post-pandemic period.

There are global concerns in the dissemination and transmission dynamics of emerging and reemerging infectious diseases and the underlying features of gain-of-function research and geopolitics within and across borders. These concerns have become pertinent in the management of local and global health because the disease is perspicuously a geopolitical issue ostensibly linked to gain-of-function research where health diplomacy focuses on the present and future global emergence and re-emergence of infectious diseases, pandemics, and microbiome variants. These have generated vehement reactions with a propensity for extreme geopolitics and gain-of-function natural and anthropogenic activities. Geopolitical parameters and gain-of-function issues impact the social determinants of health and vice versa. The convening and convergence of countries for unprecedented epidemic or pandemic treaty settings or other formulations to confront emerging and reemerging infectious diseases will afford considerable opportunities concerning challenges in action, preparedness, and response. Provisions are pertinent for legal instruments, effective and efficient systems to curb future threats and outbreaks of infectious diseases. 

SARS-CoV-2 revisits a children’s fairy tale, the Emperor’s New Clothes. The swindler- salesmen are Biden, Fauci, et al. The magical clothes are their deliberate “pandemic of fear,” and the duped emperor is the American public.Extensive evidence is presented here of a great scam. The data details the true and low health risks of SARS-CoV-2; viral biology of natural immunity and the immune response from experimental mRNA gene therapy; side effects of the “jab;” and the draconian consequences of federal mandates. Differences between official pronouncements and scientific data are highlighted.The goal of the SARS-CoV-2 Big Con or scam is the nullification of the U.S. Bill of Rights in order to restore tyranny over the American public. We the People can fight for freedom with ballots and dollars.

Environmental and behavioral factors are very important for exposure to airborne SARS-CoV-2. Indoor environments are related to infection events, including super-spreader events and outbreaks. Indoor, poorly ventilated, and crowded areas, such as restaurants, cinemas, and bars can be effective in the accumulation of aerosols full of viruses, especially if people are in conversations and stay there for a long time period. At longer distances (more than 1.5 meters), small aerosols that can stay in the air for a longer period of time are dominant. The super-spreader events in which people have been infected at a distance away show that this remote transmission occurs. The exposure risk to longer intervals is likely to be more in domestic environments and indoor spaces that lack sufficient ventilation. Layer interventions are of fundamental importance. Therefore, it is important to take preventive measures as much as possible and follow them as carefully as possible, because no intervention alone will be effective in eliminating the risk. These include spacing, lining, hand hygiene, filtration, and ventilation.

The effect of the novel coronavirus (SARS-CoV-2) pandemic has produced significant health concerns negatively impacting individuals. As the ongoing and constantly changing nature of SARS-CoV-2 continues, the unique characteristics of this pandemic trend toward anxiety and loneliness as significant behavioral health outcomes. Furthermore, the SARS-CoV-2 pandemic has significantly impacted the utilization of social media platforms such as Twitter. Utilizing over 1.6 million tweets from approximately 988,760 Twitter users geolocated in Washington state from the University of Pennsylvania’s publicly available Twitter database (from March 2020 to March 2021), this study evaluated the impact of SARS-CoV-2 by using expressions of loneliness and anxiety to predict mental and physical symptoms. Bivariate correlations revealed expressions of loneliness were correlated to trouble breathing while expressions of anxiety were correlated to skin lesions, body aches, flu-like, seasonal cold, trouble breathing, nausea or diarrhea, fever, chills, and cough. Multiple multivariate linear regressions were completed, and a significant regression equation was found in predicting trouble breathing symptoms on expressions of loneliness and anxiety, however, the proportion of variance was 8% of the observed variation in the model. Further implications revealed the importance of understanding mental and physical well-being during a public health crisis as well as the use of social media platforms as primary and supplementary stimuli.

SARS-CoV-2 is a virus that has a positive-sense, single-stranded RNA genome that encodes 4 structural proteins, the main one being the S protein (Spike) responsible for mediating with ACE2 and TMPRSS2 for entry into the host cell. The study of single nucleotide polymorphisms (SNPs) of ACE2 and TMPRSS2 can elucidate their possible intervention in the action of the protein, its activity, and the gene expression of encoding these enzymes, which may increase susceptibility to viral infection. From this, literature searches were carried out until December 2021, listing 11,820 publications for literary analysis on the described genetic variations of these protein structures, as well as their relation and influence on the pathology. It was possible to conclude that there is a great influence exerted by genetic variability in ACE2 and TMPRSS2 increasing the ability of the virus to bind to the host cell and the development of COVID-19 with complications. 

Background: From the first COVID-19 case in Playa del Carmen, 370 cases of infection have been reported in our staff until December 31, 2020. Material and methods: Study in workers of the General Hospital who developed SAR-CoV-2 infection during the pandemic. A sample of 30 cases of both sexes with laboratory-confirmed infection was obtained. Descriptive statistics were used with measures of central tendency, dispersion and percentages. Results: In a sample of 30 workers there were 13 doctors, 6 nurses and 11 support workers. The age was obtained as a mean of 38.8 years and SD = 10.4. Only four risk factors were found. Of the 30 infected health workers, 27 were treated on an outpatient basis and three required hospitalization. Discussion: The main symptoms in health workers are alterations in the sensation of taste and smell, but unlike our study, was headache, fever and myalgia. Likewise, it has been observed that medical are the most affected, but in this study it was support and the least affected was nursing personnel. There is no doubt that asymptomatic carriers are a serious disease transmission problem such that transmission between health workers by asymptomatic carriers is possible as was observed in this analysis.

Introduction: The world is currently facing the SARS-CoV-2 pandemic with evolving 2nd wave. The COVID-19 patients present most commonly with Severe Acute Respiratory Illness (SARI) in an emergency room with acute onset fever, cough, and breathlessness. However, not all SARI cases as per definition are due to COVID-19 infection, which is well proven in this case series of 113 cases of SARI. This is just the opposite of the other SARI series done in the pre-COVID-19 era. Also, no previous SARI case series data has shown significant association with Diabetes Mellitus, including new-onset diabetes thus figuring out the major Pathophysiological association of COVID-19 with glucose metabolism and has a bearing on the pathogenesis, treatment, and outcome of COVID-19 infection and perpetuity of pandemic of this magnitude. Here we raise concern for the first time about the growing association of an infectious pandemic with the lifestyle disorders which are non-communicable diseases but carry with them the potential of fertile soil for rapidly spreading epidemics.Aim and objective: To find out the etiology, clinical profile, treatment outcome, and mortality rate in different sub-groups of SARI cases in a tertiary care hospital and the incidence of new-onset Diabetes Mellitus in them and to investigate theoretically the hypothesis that maintaining normal glucose metabolism could prevent progression of a mild Flu-like illness (FLI) to a severe form of Severe Acute Respiratory Illness (SARI) and consequent complications such as Cytokine Storm Syndrome and Multi-Organ failure.Design: Retrospective, single-center case series of 113 SARI patients at a tertiary care hospital in Agra India between 1 March- 30 October 2020.Main outcome: The demographics, clinical, pathological, imaging, and treatment outcome data were collected. The SARI cases analyzed were defined as “Severe acute respiratory infections (SARIs) an acute respiratory illness of recent onset (within seven days) manifested by fever (≥38°C), cough and shortness of breath or difficulty in breathing requiring hospitalization and were sub-classified according to the primary etiology producing SARI in them. The findings were compiled and compared. Conclusion: Of the 113 patients of SARI – 32.7 %were associated with Diabetes, with 9.74% new-onset Diabetes and 26 % previously known Diabetes. This was mainly due to SARS-CoV-2 (24 Diabetics out of 52 COVID-19 cases- 46.1 %).The Average hospitalization stay of SARI cases was 10 days with a maximum in SARS-CoV-2 and a minimum stay of 5.22 days in Bacterial Pneumonia and 5.66 days in Koch’s Lungs.The death rate was maximum (4 out of 26) 15.3%. Hospitalized TB/Koch’s Lung patients who presented as SARI and 3.8% in Bacterial Pneumonia, 2.43% in SARS-CoV-2, and <1% in Sepsis.Those SARI cases who were euglycemic at the time of initial presentation recovered early and carried a good prognosis with less mortality as compared to those who were hyperglycemic on presentation. Also, those FLI cases who maintained euglycemia or did not have any other risk factor which predisposes them to stress (Diabetes, Prolonged fasting, Obesity, major organ disorder, Psychological disorder, and Cancer) did not progress to SARI as the endogenous steroid secretion and sympathetic activation did not occur, the intracellular pH levels remained in the alkaline range.10.18% of cases developed new-onset diabetes (a total of 11 cases) out of which 10 were in COVID-19. Thus 19.2% incidence of new-onset diabetes in SARS-CoV-2 and a prevalence of 26.9% in SARS-CoV-2, making total diabetes 46.1% in SARS-CoV-2, and out of all SARI cases, 26 % of patients developed pulmonary fibrosis with consequent long-term complications. In COVID-19 patients, it was seen only in diabetics SARS CoV-2 male patients, thus no death in non-diabetic females in COVID-19 in this case series.

The SARS-CoV-2 (COVID-19) pandemic outbreak has led to some lockdowns and changed human mobility and lifestyle in this country. Mashhad, one of the most polluted cities in Iran has experienced critical air pollution conditions in recent years. In the present study, the potential relationships between air quality conditions (such as popular index and criteria air pollutant concentration) and COVID-19 cases and deaths were investigated in Mashhad, Iran. To do that, the Long Short-Term Memory (LSTM) based hybrid deep learning architecture was implemented on AQI, meteorological data (such as temperature, sea level pressure, dew points, and wind speed), traffic index and impact number of death, and active cases COVID-19 from March 2019 to March 2022 in Mashhad. The results reveal the LSTM model could predict the AQI accurately. The lower error between the real and predicted AQI, including MSE, MSLE, and MAE is 0.0153, 0.0058, and 0.1043, respectively. Also, the cosine similarity between predicted AQI and real amounts of it is 1. Moreover, in the first peak of the pandemic (Aug 2021), we have the minimum amount of AQI. Meanwhile, by increasing the number of active cases and death and by starting lockdown, because the traffic is decreased, the air quality is good and the amount of AQI related to PM2.5 is 54.68. Furthermore, the decrease the active cases and death in pandemic causes a significant increase in AQI, which is 123.52 in Nov 2021, due to a decline in lockdowns, resumption of human activities, and probable temperature inversions. 

Background: COVID-19 is the extreme smash of the present-day century that emaciated fitness, financial system, and ordinary life.Objectives: This research assessed the condition and relation of tests, infections, recoveries, and deaths of SARS-CoV-2 from January to May 30, 2022. Methods: The research plan was carried out from January 1 to May 31, 2022 (n = 151 days) to state the position of Bangladesh towards widespread COVID-19. The facts in this study became acquired from extraordinary government groups.Results: The total cases, infections, recoveries, and deaths were 2633750, 367208, 357309, and 1053, respectively, during the study period. In January 2022, the total number of COVID-19 tests, infections, recoveries, and deaths was 987194, 213294, 19112, and 315, respectively. In February 2022, the total number of COVID-19 tests, infections, recoveries, and deaths was 922657, 143744, 250422, and 643, respectively. In March 2022, the total number of COVID-19 tests, infections, recoveries, and deaths was 353555, 5810, 49727, and 63, respectively. In April 2022, the total number of COVID-19 tests, infections, recoveries, and deaths was 152691, 977, 12490, and 7, respectively. In May 2022, the total number of COVID-19 tests, infections, recoveries, and deaths was 127950, 1016, 6166, and 4, respectively. The maximum and the minimum number of COVID-19 tests were 49492 and 1653 on January 25 and May 4, respectively. The maximum and the minimum number of COVID-19 infestations were 16033 and 1653 on January 22 and May 5, respectively. The maximum and minimum number of COVID-19 recovered were 13853 and 1653 on February 13 and May 9, respectively. The maximum and the minimum number of COVID-19 death was 43 and 0 on February 8 and in several days in 2022, respectively. In the 0.01 level of the two-tailed Spearman, the relationship was positive to moderate to strong relationships and the total number was n=151. The mean Spearman correlation for tests was 0.83 (range 0.973 to 0.633), for infested was 0.81 (range 0.579 to 0.973), for recovered was 0.61 (range 0.633 to 0.618), for death was 0.81 (range 0.553876 to 0.618). This research additionally showed a moderate to strong relationship between tests, infections, recoveries, and deaths of SARS-CoV-2.Conclusion: COVID-19 has spread out unexpectedly to 64 districts in Bangladesh. The persevering with the occurrence of COVID-19 infections has emphasized the significance of the short and accurate and advanced 118 laboratory diagnoses to restriction it unfolds. In this situation, human beings must keep away from public gatherings as plenty as possible and pass return home as speedy as possible after finishing work in a public place. It is safer now because the vaccine controlled the infestation and death rate of COVID-19 in Bangladesh.

For over two years, COVID-19 pandemic has been a major global health concern and threat to human life. In the SARS-CoV2 macromolecules, the 3-chymotrypsin like protease (3CLpro or main protease) has been identified to be crucial and essential for viral survival, processing of the viral polyproteins and has been explored as a target in COVID-19 drug discovery. Although vaccines and other various inhibitors have been designed and launched, the emergence of the variant of this virus has put an unrelenting effort of researchers to this end. Also, the high cost of manufacturing these molecules coupled with the occurrence of drug resistance is a concern.Herein, Pefloxacin and its derivative for the first time were screened for their inhibitory activity against the SARS-CoV2 main protease through in silico analysis and their pharmacokinetic properties were evaluated. Interestingly, from the docking results, they both bind with high affinity at the active site of the protein. Moreover, they showed excellent pharmacokinetic and drug - likeness properties. Derivatization of Pefloxacin at the C7 position prevents its blood-brain barrier permeability. Overall, the dual antibacterial and potential antiviral activities of these two molecules make them promising drug candidates for COVID-19 management.

The SARS-CoV-2 pandemic is still ongoing. Previously, several studies have been conducted to investigate laboratory markers as a tool for severity assessment during COVID-19 infections. Biological markers such as Platelet count, D-dimer and IL-6, Lymphocytopenia and others have been used for assessment of severity in COVID-19 disease patients (infected by SARS-CoV-2 Alpha, Beta, Gamma, Delta, Epsilon, and other variants). We observed a significant drop in lymphocyte count among suspected SARS-CoV-2 clinical patients with symptoms of fever, running nose, breathing discomfort, cough, and others during Omicron and Centaurus variants spread in Pakistan. A multicenter, cross-sectional study was conducted from Jan 2021 to Aug 2022, on 118,561 subjects to evaluate hematological abnormalities among suspected patients. Of note, significantly decreased lymphocyte levels (lymphocytopenia) were observed among 43.05% of infected patients. Also, the levels of NA (39.03%), HGB (28.27%), MCV (22.62%), PLT (8.17%), and ALB (4.30%) were also reduced among infected patients. This suggests that lymphopenia can be used as an alternative, cost-effective, early diagnostic biomarker for clinical COVID-19 patients, even before the diagnosis via real-time PCR. In resource-limited countries, the current study is critical for policy-making strategic organizations for prioritizing lymphocytopenia-based screening (as an alternative, cost-effective diagnostic test) in clinical COVID-19 patients, before real-time PCR-based diagnosis.

SARS-CoV-2 is the virus associated with the disease called COVID-19 and become a global pandemic. The only way to prevent its severe scenarios is through timely and rapid testing. In comparison to more time taking gold-standard RT-PCR testing, rapid diagnostic kits are used. For better prevention and diagnosis of SARS-CoV-2, the analysis of rapid diagnostic kits' accuracy and specificity is necessary. This study is meant to assess and examine the viability, responsiveness, and explicitness of quick antigen distinguishing nasopharyngeal swabs (NPS), and saliva-based units. The study was conducted on 200 suspected COVID-19 patients from Islamabad, 100 of which were RT-PCR positive while 100 were RT-PCR negative. For the analysis of Rapid diagnostic COVID-19 kits (RDT), nasopharyngeal swabs (NPS) and saliva samples were taken from the RT-PCR positive and negative patients. Among 100 RT-PCR positive patients, 62% were males (19 - 91 years), 34% were females (20 - 78 years) and 4% were children (6 - 17 years). False-negative results were significantly more observed in saliva-based RDTs of the sample (49%) as compared to nasopharyngeal swab RDT (38%). There were 2% invalid results in saliva-based RDT and 3% invalid results in Nasopharyngeal swab RDT. While among 100 RT-PCR negative patients 69% were males (19 - 80 yrs), 27% were females (18 - 77 yrs) and 4% were children (12 - 16 yrs.). False positive results were significantly more in saliva-based RDT (22%) as compared to Nasopharyngeal swab RDT (13%). The sensitivity and specificity of saliva-based RDT were 67% and 87% respectively while that of Nasopharyngeal swab (NPS) was 72% and 82% respectively, both of which were less than the gold standard RT-PCR sensitivity demanding the introduction of more sensitive RDT kits in Pakistan for accurate detection of COVID-19.

Determining the extent of immunity induced by booster doses of COVID-19 vaccinations is crucial for informing recommendations for booster dose regimens as well as constant adjustments of immunization strategies amongst different groups of people within the population. The study involved 31 healthy volunteers (majority were healthcare professionals) who completed either vaccination course with Pfizer or Moderna mRNA vaccines and received a third dose of the vaccine. Here we report results on the evaluation of an antibody response to four different SARS-CoV-2 antigens: RBD, S1, S2 and nucleocapsid prior to third dose and two and four weeks after a booster vaccination. We detected a peak of high titers of antibodies after the third dose with a gradual decline after four weeks. No significant differences were seen between the two vaccines in terms of antibody response. There were no gender discrepancies between the two vaccines. Our results suggest that: third doses are necessary due to the emergence of different SARS-CoV-2 variants and postvaccination antibody testing continues be essential in determining possible standardization of SARS-CoV-2 vaccines regimens.

Information regarding the effects of the novel coronavirus on human reproduction is currently limited. The objective of our work was to assess whether, in women who have passed the disease, there was a variation in the ovarian reserve through the determination of AMH levels. During May-June 2020, women performing an Assisted Reproductive treatment and who had a positive IgG for SARS-CoV-2 were included in the study; this group of women had a previous AMH determination of no more than 6 months. Women were stratified into two groups, according to their previous AMH levels: low responders (AMH<1 ng/ml) or normal-high responders (AMH ≥ 1 ng/ml) Statistical analyses were performed using the Statistical Package for Social Sciences 19.0 (IBM Corporation, Armonk, NY, USA). A total of 46 patients were included in the study; 16 women were diagnosed as having low ovarian reserve (AMH < 1 ng/ml), with an average age of 38.6 years, whereas 30 were classified as having normal ovarian reserve (AMH ≥ 1 ng/ml), with an average age of 34.7 years. Generally, the data show no variation in AMH levels before and after SARS-CoV-2 infection (1.73 ng/ml vs. 1.61 ng/ml, respectively). However, when we analyzed these differences according to the study groups, the results were consistent with the patient's ovarian status. It is possible to conclude that the fact of having passed the disease does not affect the ovarian reserve status but the degree of the variation of AMH levels depending on the patient was a low or high responder.

Introduction: The spread of SARS-CoV-2 cases grew exponentially. In Mexico, it focused mainly on containing the disease and adopting activities and actions to mitigate it. Hospital reconversion was a fundamental strategy in the management of care for patients with COVID-19.Objective: To know the clinical characteristics of patients admitted with respiratory disease and probable COVID-19 in the Zacatecas General Hospital “Luz González Cosío” México.Material and methods: Descriptive, cross-sectional, and analytical study, at the General Hospital, from March 2019 to September 2021; using data from the Respiratory Disease Surveillance System. Data from patients admitted with a diagnosis of some pathology of respiratory disease and probable COVID-19 were analyzed.Results: We included 2,678 diagnosed with respiratory disease and a mean age; of 47.6 ± 21.6 gender distribution was almost equal; women 1,344 (51.0%). positive result to COVID-19 by PCR; 1,654 negatives; 900 and 124 without result. 193 (7.0%) required mechanical ventilation. The presence of comorbidities was evaluated; type 2 diabetes mellitus, systemic arterial hypertension, obesity, alone and together. Also the association of the age factor, as well as the lethality index; was 531 (19.6%).Discussion: What has been published in other studies about comorbidities and their influence on the severity of COVID-19 is confirmed, disagreeing on the case fatality rate; 20.7% against what was reported; 17.6% in other countries for COVID-19 hospitalized. An age variable was used as a risk factor with a cut-off point > 45 years; (FRE), obtaining; RR 3.42 (95% CI 2.79 to 4.19) and an odds ratio of 4.015 in binary logistic regression analysis. Reported male mortality (OR = 1.45; 95% CI: 1.41–1.51) according to our OR results; 1,45.Conclusion: The present study shows how certain chronic diseases influenced respiratory disease to present a serious state, regardless of the positive or negative result of COVID-19.
