Wuhan mass screening identifies hundreds of asymptomatic cases — ScienceDaily

A mass screening programme of more than 10 million Wuhan residents identified 300 asymptomatic cases, but none were infectious, according to a study involving the University of East Anglia.

The mass testing project took place over two weeks at the end of May — after the city’s stringent lockdown was lifted in April.

The study found no ‘viable’ virus in the asymptomatic cases and the close contacts of these positive asymptomatic cases did not test positive.

But the research team warn that their findings do not show that the virus can’t be passed on by asymptomatic carriers.

Rather, strict non-pharmaceutical interventions such as mask-wearing, hand washing, social distancing and lockdown have helped reduce the virulence of Covid-19.

The study, published in Nature Communications, was led by researchers at the Huazhong University of Science and Technology (HUST) in Wuhan, China — in collaboration with researchers at UEA’s Norwich Medical School.

Children with asymptomatic brain bleeds as newborns show normal brain development at age 2 — ScienceDaily

In 2007, UNC researchers published unexpected and surprising results from a study based on magnetic resonance imaging (MRI) of newborn brains. Twenty-six percent of the newborns in the study were found to have asymptomatic subdural hemorrhages, or bleeding in and around the brain.

It was an unexpected finding because subdural hemorrhage had been considered unusual in full-term newborns. But the 2007 findings suggested that small, asymptomatic brain bleeds might be a fairly common consequence of a normal vaginal delivery.

Now 13 years later, John H. Gilmore, MD, professor and vice chair of research in the UNC Department of Psychiatry and senior author of the 2007 study, and J. Keith Smith, MD, PhD, vice chair of the UNC Department of Radiology, have published a follow-up study in the journal Radiology, which also published the 2007 study.

“We were one of the first groups to systematically scan the brains of newborns
