COVID-19 asymptomatic infection estimation

Mounting evidence suggests that there is an undetected pool of COVID-19 asymptomatic but infectious cases. Estimating the number of asymptomatic infections has been crucial to understand the virus and contain its spread, which is, however, hard to be accurately counted. A new study proposes an approach of Machine Learning based fine-grained Simulator (MLSim), which integrates...

Doctors are finding damage in kidneys, hearts and elsewhere by COVID-19

The coronavirus kills by inflaming and clogging the tiny air sacs in the lungs, choking off the body’s oxygen supply until it shuts down the organs essential for life. But clinicians around the world are seeing evidence that suggests the virus also might be causing heart inflammation, acute kidney disease, neurological malfunction, blood clots, intestinal...

Clinical manifestations of children with COVID-19

Elderly patients infected with SARS-CoV-2 are at high risk to have Severe Acute Respiratory Syndrome (SARS), complications and death. Due to unknown reasons, children with COVID-19 appear to have a milder clinical course compared to adults, and reports of death are scarce. However, pediatric population may play a major role in community spread of SARS-CoV-2....

Asymptomatic and pre-symptomatic patients infected with COVID-19

Asymptomatic but infectious people have been reported in many infectious diseases. Examples include herpes, cytomegalovirus and respiratory diseases caused by viruses such as H1N1 or H5N1 influenza, being asymptomatic and pre-symptomatic people a reservoir hidden for detection systems. The Chinese government first reported the infection as pneumonia of unknown origin in late December 2019; then...

Impact of asymptomatic carriers on COVID-19 transmission

Asymptomatic carriers of the virus display no clinical symptoms but are known to be contagious. Recent evidence reveals that this sub-population, as well as persons with mild symptoms, represent a major contributor in the propagation of COVID-19. The asymptomatic sub-population frequently escapes detection by public health surveillance systems. Because of this, the currently accepted estimates...
