Nevertheless, a new study conducted in Brazil suggests that a single negative test result may not be enough to reassure family members [...]

Because P. falciparum, the predominant species of malaria parasite, displays low genetic diversity in the Americas compared with other regions, scientists believed the same was true for P. vivax. This belief is [...]
