Plasmodium vivax is a protozoal parasite and a human pathogen.This parasite is the most frequent and widely distributed cause of recurring malaria. [2] Although it is less virulent than Plasmodium falciparum, the deadliest of the five human malaria parasites, P. vivax malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen).
Five recent malaria cases were the first in 20 years to be acquired in the U.S. rather than during travel outside the country. Four were reported in Florida and one in Texas.
According to the WHO's World Malaria Report 2015, the global mortality rate for malaria fell by 60% between 2000 and 2015. The WHO targeted a further 90% reduction between 2015 and 2030, [64] with a 40% reduction and eradication in 10 countries by 2020. [65] However, the 2020 goal was missed with a slight increase in cases compared to 2015. [66]
