Nearly 3 billion people are at risk of infection with the malaria parasite Plasmodium vivax, according to a new analysis published this week in PLoS Neglected Tropical Diseases. The P. vivax parasite has long been considered the milder, less-dangerous cousin of P. falciparum. But recent studies have made clear that P. vivax can also cause deadly complications in infected people.
