Public health experts are warning that protests over police violence could worsen the spread of the novel coronavirus.
Reuters reports that cities all over the world are protesting the violent death of an unarmed black man, George Floyd.
The protests are bringing together hundreds, sometimes thousands, of people into one concentrated area.
Health experts say the close proximity of protestors along with yelling or chanting, may increase transmission.
The transmission rate may be higher because people emit more respiratory droplets under these conditions.
Experts say that if you attend a protest, you should consider yourself exposed.and should get a test immediately.
