But taking them cuts your chances of getting sick by about 90%. The precise mechanism by which Chloroquine exhibits activity is not known. In the case of chloroquine and hydroxychloroquine, the drugs alter the chemical conditions inside cells in a way that kills malaria parasites, suppresses some undesired immune reactions, and might keep SARS-CoV-2 from replicating inside cells. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial.
