This is just one person. Is he the exception? Is he the rule? We don’t know yet for sure. But reinfection is definitely possible.
Reports describe a Hong Kong man who was reinfected with the coronavirus after returning from Europe. Does that mean he wasn’t immune after the first infection?

As grim as things are with the pandemic raging in the US and the mounting death toll, there are many reasons to be optimistic there will be a vaccine by early next year.
Some people’s blood can mount an immune response against SARS-CoV-2, even if those blood samples were taken from before the COVID-19 pandemic started.
Researchers can’t agree on topics such face mask, immunity and number of infections. Here’s why.
If immunity is short-lived, we will be in an ongoing cycle of endless reinfection.
There is speculation about whether a population can achieve some sort of immunity to the virus with as little as 20% infected.
The antibody can be used to diagnose Alzheimer’s disease.
Tobacco has imposed a terrible toll on global health, but it could be used to produce the molecules we need to fight COVID-19.
Antibodies that recognize and block SARS-CoV-2 infection have the potential to be powerful weapons. An infectious disease expert explains what antibodies are and how they could be used as a therapy.
Our experts look at recovery efforts, how different the post-pandemic world will be, the hunt for a cure for COVID-19, and why we need to mind our mental health.
An antigen test was given emergency use authorization by the FDA in early May. A biochemist explains how COVID-19 antigen tests work.
Amazon and General Motors are among companies exploring ways to test employees for COVID-19 infection, but these measures may be against the law.
Immunity to COVID-19 may be complicated. Here are the promises and pitfalls of antibody tests.
‘Nanobodies’ produced by the llama immune system can neutralise the virus that causes COVID-19.
Expanding coronavirus testing is one of the most important tasks public health officials are tackling right now. But questions over accuracy of the two main types of tests have rightly caused concern.
The science is far from certain, but it appears at least a proportion of people who have had COVID-19 will be protected from another infection – at least initially.
Your body can be infected and fight off SARS-CoV-2 without your ever noticing.
