A new study finds even mild cases of COVID-19 trigger people’s immune systems to produce antibodies against the novel coronavirus. The findings by researchers at the Pasteur Institute in France raise hopes that most people who contract the coronavirus will have some form of immunity against a second infection.
Meanwhile, researchers at the University of California, Santa Barbara say six feet of social distance might not be enough to stop the spread of the coronavirus, especially in cold and humid weather. The researchers found that under certain conditions, droplets carrying the virus can travel up to 20 feet after they’re exhaled by infected people. The finding was published on a preprint server and has not yet been peer reviewed.
