Jul 19, 2023 · Still, there are plenty of outstanding questions about asymptomatic COVID-19. For example, only 20% of the asymptomatic people in the study had the HLA-B*15:01 mutation, and it’s not clear why ...
Jul 20, 2023 · Scientists estimate that over 20% of people who get infected with COVID never have any symptoms – and a portion of them never even know they were infected. Now a new study published in Nature on ...

At the beginning of the pandemic, scientists focused intensely onunderstanding what makes people more vulnerable to severe COVID-19 — which we've since learnt includes factors like old age, underlying health conditions, and obesity. These days, an increasing amount of research is being devoted to the other side of the coin: why do some people seem ...
Adding to that complex picture of individual protection and risk is the possibility of previous infection. Professor Tangye said it was likely that many Australians had been infected with COVID-19 without realising it. "When we first started doing PCR testing, it was really done on symptomatic people … so we were obviously missing a lot of those as...
Putting aside environmental factors and protection induced by vaccination (and previous infection), experts say there may be particular genetic and immunological features that mean some people are naturally more resistant to COVID-19. Earlier this year, UK researchers deliberately exposed a group of 36 young, healthy individuals — with no evidence ...
Dr Bryant said research previously done by the COVID Human Genetic Project on why some people were — conversely — genetically susceptible to severe disease had already led to improved understanding and treatments. In 2021, researchers discovered that individuals with genetic mutations that disrupt the activityof proteins critical to fighting off vi...

Jan 23, 2023 · They are being called “super-dodgers,” or Novids, or COVID virgins. They are the people who have somehow not been infected with COVID-19 yet, despite 663 million cases worldwide. Researchers hope to learn if they have some unknown antibody, or genetic code, or mysterious cell makeup, that has helped them ward off COVID better than others.

Apr 21, 2022 · Given that at its peak in January, more than 800,000 people were getting COVID-19 on average each day, questions have swirled about how some people have managed to escape the coronavirus so far ...

Aug 24, 2021 · While we do not know exactly why some COVID-19 cases cause symptoms and others do not, research is growing on this topic and there are a number of hypotheses for why asymptomatic cases occur. These include the following: Age: Young people have been shown to have much higher amounts of asymptomatic cases than older people. A recent study by Duke ...
Mar 2, 2022 · Scientists seek to solve mystery of why some people do not catch Covid. Experts hope research can lead to development of drugs that stop people catching Covid or passing it on. P hoebe Garrett has ...
