Clinical spectrum and complications of Plasmodium vivax malaria: A retrospective study from Delhi, India

Nearly half of <i>P. vivax</i> cases developed severe complications, challenging its benign perception. Anaemia, thrombocytopenia, leucocytosis, and organ dysfunction were key severity markers. Higher complication rates in females and afebrile cases highlight diagnostic and social challenges. Early recognition of atypical features and vigilant monitoring are crucial to improve outcomes in endemic regions.
