Quinine may be used to treat vivax malaria but is associated with inferior outcomes.

As such, vivax malaria offers the two Koreas an opportunity to work together on an important health problem that affects both countries.

The common Anopheles mosquito ensures that vivax malaria is endemic.

This was more rapid that is found in Plasmodium vivax malaria where the median time to clearance is between six and seven hours.

Another 40 percent of cases are caused by vivax malaria, which leads to fevers, anemia and debility, but rarely kills.

P. vivax malaria in a Duffy antigen negative individual in Mauritania has also been reported.

The drug is also increasingly being used in Plasmodium vivax malaria, as well as being a topic of research in cancer treatment.

P. vivax malaria cases in temperate areas often involve overwintering by hypnozoites, with relapses beginning the year after the mosquito bite.

It is less virulent than Plasmodium falciparum, the deadliest of the five, and but vivax malaria can lead to severe disease and death.

These variants are believed to stem from a protective effect against Plasmodium falciparum and Plasmodium vivax malaria.

A patient infected with known or suspected chloroquine-resistant P. vivax malaria should receive an alternative first-line agent (i.e., quinine plus clindamycin or doxycycline, atovaquone-proguanil, mefloquine).

Mefloquine does not eliminate parasites in the liver phase of the disease, and people with P. vivax malaria should be treated with a second drug that is effective for the liver phase, such as primaquine.

Where an artemisinin-based combination therapy has been adopted as the first-line treatment for P. falciparum malaria, it may also be used for P. vivax malaria in combination with primaquine for radical cure.

She suffered from both P. falciparum and P. vivax malaria and while forms similar to those described for P. tenue were found in her blood even the author was skeptical about the validity of the diagnosis.

For these and other reasons, the doctors said, the agency considers anyone with vivax malaria to have had a relapse from a primary infection if the person had traveled to an endemic area within the previous four years before becoming ill.
