Sep 18th, 2021 - SARS-CoV-2 can remain transiently viable on surfaces. We examined if use of shared chairs in outpatient hemodialysis associates with a risk for indirect patient-to-patient transmission of SARS-CoV-2. We used data from adults treated at 2,600 hemodialysis facilities in United States between February 1st and June 8th, 2020. We performed a retrospective case-control study matching each SARS-CoV-2 ...

Sep 16th, 2021 - The rapid spread of the Delta variant suggests that SARS-CoV-2 will likely keep rampant for months or years and could claim millions of more lives. All known vaccines cannot well defeat SARS-CoV-2 except neglected live attenuated vaccines (LAVs), which could have much higher efficacy and much higher production efficiency than other vaccines. LAVs have well defeated more pathogenic viruses than ...

Sep 16th, 2021 - In this study, we formulate and analyze a deterministic model for the transmission of COVID-19 and evaluate control strategies for the epidemic. It has been well documented that the severity of the disease and disease related mortality is strongly correlated with age and the presence of co-morbidities. We incorporate this in our model by considering two susceptible classes, a high risk, and a l...

Sep 15th, 2021 - Mother-to-child transmission of SARS-CoV-2 might occur during the antepartum (in utero), intrapartum, and/or postpartum period. Theoretically, in utero transmission is possible in cases of maternal COVID-19 infection due to disruption in the placental interface or viral particles in the amniotic fluid as a result of viremia. Intrapartum and postpartum transmission might occur due to the neonate...
