What are the Clinical Features of Plasmodium Vivax Malaria?

The clinical features of P. vivax malaria include fever, chills, headache, and muscle pain. It is characterized by a cyclical fever pattern that recurs every 48 hours. Although it is generally less severe than P. falciparum malaria, P. vivax can still cause significant morbidity, including severe anemia and, in rare cases, acute respiratory distress syndrome (ARDS). The presence of hypnozoites means that individuals can experience relapses weeks to months after the initial infection.
