Anvisa restricted sale of chloroquine after great demand for the drug at the beginning of the year

A new study concluded that taking chloroquine does not prevent covid-19, the disease caused by the new coronavirus.

Scientists at the University of Pennsylvania in the United States tested whether the drug, used against lupus and malaria, had this effect on 125 health professionals.

Participants were divided into two groups: 64 received chloroquine and 61 received placebo for eight weeks.

In the end, it was found that there was no significant difference in the proportion of people who were infected.
