Sewer slime can hang on to SARS-CoV-2 RNA from wastewater
During the COVID-19 pandemic, monitoring the levels of SARS-CoV-2 RNA in wastewater entering treatment plants has been one way that researchers have gauged the disease's spread. But could the slimy microbial communities that line most sewer pipes aff.....»»
Machine learning IDs mammal species with the potential to spread SARS-CoV-2
Back and forth transmission of SARS-CoV-2 between people and other mammals increases the risk of new variants and threatens efforts to control COVID-19. A new study, published today in Proceedings of the Royal Society B, used a novel modelling approa.....»»

New study finds evidence of COVID antibodies in breast milk of vaccinated mothers
Researchers found that two groups of mothers -- those who had disease-acquired immunity and those with vaccine-immunity -- had high levels of antibodies in their breast milk, and these antibodies provided neutralization against SARS-CoV-2......»»
Unstable housing, homelessness associated with COVID-19 re-infection
New study results demonstrate that unstable housing and homelessness is associated with a two-fold greater chance of being re-infected with SARS-CoV-2 compared to those who are securely housed. The research indicates that unstable housing was the onl.....»»

SARS-CoV-2 variant detected in dogs and cats with suspected myocarditis
A new study in the Veterinary Record reveals that pets can be infected with the alpha variant of SARS-CoV-2, which was first detected in southeast England and is commonly known as the UK variant or B.1.1.7. This variant rapidly outcompeted pre-exi.....»»
COVID-19 Virus Does Not Infect Human Brain Cells, Study Suggests
An anonymous reader quotes a report from The Guardian: The virus that causes Covid-19 does not infect human brain cells, according to a study published in the journal Cell. The findings will raise hopes that the damage caused by Sars-CoV-2 might be m.....»»

SARS-CoV-2 virus can infect the inner ear, study finds
The SARS-CoV-2 virus can infect cells of the inner ear, including hair cells, which are critical for both hearing and balance, a new study suggests. Researchers also found that the pattern of infection seen in human ear tissue is consistent with the.....»»
Children, adults equally vulnerable to coronavirus infection, but children less likely to become sick, research finds
New research addresses the misconception that children are less susceptible to infection with the new coronavirus. According to a recent report, children and adults have similar risks of becoming infected with SARS-CoV-2, but a much larger proportion.....»»
