Why is coronavirus deadly for some, but harmless in others?
To figure out what makes some people more vulnerable to severe cases of covid-19, we need to rethink what we know about infection

Can You Get Covid-19 Again? It’s Very Unlikely, Experts Say
Reports of reinfection instead may be cases of drawn-out illness. A decline in antibodies is normal after a few weeks, and people are protected from the coronavirus in other ways.

What if ‘Herd Immunity’ Is Closer Than Scientists Thought?
In what may be the world’s most important math puzzle, researchers are trying to figure out how many people in a community must be immune before the coronavirus fades.

Why do asymptomatic COVID-19 cases even happen?
Health officials are concerned about why some people who test positive for the coronavirus never feel sick. Could it be the luck of genetics? The blessings of youth? Or something else?

Most People With Coronavirus Won’t Spread It. Why Do a Few Infect Many?
Growing evidence shows most infected people aren’t spreading the virus. But whether you become a superspreader probably depends more on circumstance than biology.

Asymptomatic Transmission? We Just Don't Know Yet for Certain
There has been confusion about whether people infected with SARS-CoV-2 who do not have symptoms can transmit to others. In fact, we do have evidence that individuals without symptoms can spread the virus. This is the likely reason why SARS-CoV-2 has been harder to contain than its relative, SARS-CoV. Nonetheless, it is hard to detect this type of transmission, and it is even harder to measure how frequently it occurs.
