Around 3.4 million people in England — 6% of the population — have contracted coronavirus, with infection rates twice as high in London, a major antibody study found.

A mass survey of more than 100,000 people — which the government says is the biggest of its kind in the world — suggested the extent of the outbreak varied widely between different areas and population groups...

As some countries begin to reopen in the midst of the ongoing coronavirus pandemic, experts are racing to ramp up the development and use of blood tests that pinpoint people who have been exposed to the virus that causes COVID-19 and are no longer infected.

The tests detect antibodies, proteins made by the immune system to fight infection (SN: 3/27/20). People who carry antibodies specific to the novel coronavirus, called SARS-CoV-2, have been infected previously, even if they didn’t know it. For those people, discovering that they have these virus-fighting antibodies could raise hopes of immunity and a return to normal life.

But scientists are also working to uncover what these blood tests really tell us. At this point, there isn’t enough evidence to confirm that recovered people are protected from the disease and, if so, for how long, the World Health Organization said in a statement on April 24. So people hoping for that assurance may be disappointed.

For researchers and public health officials, though, the tests can reveal the true extent of the pandemic. The U.S. National Institutes of Health announced April 10 that researchers had begun recruiting people for a nationwide study that aims to test as many as 10,000 volunteers without an official COVID-19 diagnosis, which could help clarify how many people across the country have actually been infected. A number of similar, more local studies are also under way.

The goal is to fill in the gaps created by trouble rolling out diagnostic tests, which detect the virus’s genetic material and can catch an active infection. Those tests have faced roadblocks such as flawed tests and supply shortages, leaving some sick people wondering whether their symptoms were from COVID-19 or a different respiratory infection.

Such tests can’t detect the virus once the infection has cleared. But antibodies typically stick around in the body after the virus has disappeared, giving scientists a glimpse into the past. So for people who weren’t able to get a diagnostic test, the antibody test “will give us the ability to let them know yes, you did have COVID-19,” says Aneesh Mehta, an infectious disease physician at Emory University in Atlanta.

He said this will allow for community testing outside of the Caribbean Public Health Agency’s guidelines. The method being used to test for covid19 is polymerase chain reaction…

Coronavirus antibodies are antibodies or white blood cells that help the body fight against the Coronavirus. These Coronavirus antibodies prevent and kill the increasing amount of Coronavirus from growing further. In some cases, they can be in your body since childhood, but mostly, Coronavirus antibodies are injected into the body through vaccines. Before understanding Coronavirus […]
