There’s pretty much no one left in the US who hasn’t been exposed to the coronavirus, whether by vaccination, infection or both.

Even if you’re vaccinated, you still need to come forward for COVID testing, even if you have the mildest symptoms.
Some have suggested the US allow healthy people to return to normal life, catch the coronavirus and get the population to herd immunity. The science says this plan is doomed to fail from the start.
A preliminary study published online this week estimates Australia had 60,000 undiagnosed COVID-19 infections by July. But there are a range of limitations to the study.
Answering this is not as straightforward as you might think. But a careful analysis of the data suggests the news is not great.
A team of researchers from Indiana University performed random testing for SARS-CoV-2 across the state. The results offer some of the most accurate data to date about important aspects of the virus.
An antigen test was given emergency use authorization by the FDA in early May. A biochemist explains how COVID-19 antigen tests work.
Immunity to COVID-19 may be complicated. Here are the promises and pitfalls of antibody tests.
Immunity passports have been touted as a way to reopen the economy. But there are serious concerns they’ll create an incentive to intentionally contract the coronavirus.
Testing for coronavirus has been a fiasco in the US. But now companies are developing super fast tests, including ones that might eventually be as simple as at home pregnancy tests.
Nearly two million antibody tests imported into Australia can’t be used to diagnose COVID-19. But it’s difficult to make an antibody test that is specific and sensitive enough.
If you are experiencing COVID-19 symptoms, it’s best to assume you have it – even if your test is negative.
Cellphone data can show who coronavirus patients interacted with, which can help isolate infected people before they feel ill. But how digital contact tracing is implemented matters.
A test that detects antibodies against the coronavirus behind COVID-19 would reveal those people who have already encountered the virus - and therefore who might be ok to resume normal life.
