ABSTRACT

BACKGROUND: Recent studies indicated that females have a lower morbidity, severe cases rate, mortality and better outcome than those of male. However, it remained to be addressed why this was the case. METHODS AND FINDINGS: To find the factors that potentially protect females from COVID-19, we recruited all confirmed patients hospitalized at three branches of Tongji Hospital (n=1902) from January 28 to March 8, 2020, and analyzed the correlation between menstrual status (n=509,including 68 from Mobile Cabin Hospital)/female hormones (n=78)/ cytokines related to immunity and inflammation(n=263), and the severity/clinical outcomes in female patients under 60 years of age.Non-menopausal female patients had milder severity and better outcome compared with age-matched men (p<0.01/p<0.01). Menopausal patients had longer hospitalization times than non-menopausal patients ( hazard ratio [HR], 1.91; 95% confidence interval [CI], 1.06-3.46,p= 0.033). Both anti-müllerian hormone (AMH) and estradiol (E2) showed a negative correlation with severity of infection (AHR=0.146/0.304, 95%CI = [0.026-0.824]/[0.092-1.001], p=0.029/0.05). E2 levels were negatively correlated with IL-2R, IL-6, IL-8 and TNFα in luteal phase (Pearson Correlation=-0.592, -0.558, -0.545, -0.623; p=0.033, 0.048, 0.054, 0.023), and with C3 in follicular phase (Pearson Correlation=-0.651; p=0.030). CONCLUSION: Menopause is an independent risk factor for female COVID-19 patients. AMH and E2 are potential protective factors, negatively correlated with COVID-19's severity, among which E2 is attributed to its regulation of cytokines related to immunity and inflammation. Hormone supplement might be a potential therapy for COVID-19 patients.

ABSTRACT

Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) causes the infectious disease COVID-19 (coronavirus disease 2019), which was first reported in Wuhan, China, in December 2019. Despite extensive efforts to control the disease, COVID-19 has now spread to more than 100 countries and caused a global pandemic. SARS-CoV-2 is thought to have originated in bats; however, the intermediate animal sources of the virus are unknown. In this study, we investigated the susceptibility of ferrets and animals in close contact with humans to SARS-CoV-2. We found that SARS-CoV-2 replicates poorly in dogs, pigs, chickens, and ducks, but ferrets and cats are permissive to infection. Additionally, cats are susceptible to airborne transmission. Our study provides insights into the animal models for SARS-CoV-2 and animal management for COVID-19 control.
