Abstract
Background: India is endemic for
Plasmodium vivax(Pv) malaria.
Despite a decrease in incidence, its elimination is
hampered by recurrences. This study aimed to characterize recurrences in
Pv malaria and study its association with primaquine (PQ) usage. Methods: Symptomatic adult
Pv patients were followed-up for up to 23 months for recurrences. The time to recurrence was compared by the PQ dosage they received using a log-rank test. Results: Of the 294 malaria patients, 206 (70%) patients had
Pv infection during the study period. A total of 20 (9.7%) recurrences were seen in 17 (8.2%) patients of
Pv. The percentage of first-time recurrences were highest in the no PQ group (25%), followed by the weekly PQ group (20%), low dose daily PQ (8.2%) group, and high dose daily PQ group (3.1%). Conclusions: Recurrence in
Pv malaria is common, especially in those who receive an incorrect prescription of primaquine.
