AsymptomaticPlasmodiuminfection raises a problem for the persistent transmission of malaria in low-endemic areas such as Asia. This systematic review was undertaken to estimate the prevalence and proportion of asymptomaticPlasmodiuminfection in Asia. The systematic review was registered at PROSPERO (ID: CRD42022373664). The research followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A comprehensive search of five databases, Ovid, Scopus, MEDLINE, PubMed, and Embase, was conducted to identify studies of asymptomaticPlasmodiuminfection in Asian countries. The pooled prevalence of asymptomaticPlasmodiuminfection, the pooled proportion of asymptomaticPlasmodiuminfection among all parasitised individuals, and the associated 95% confidence intervals were estimated using a random-effects model. A total of 916 articles were retrieved, and 87 articles that met the criteria were included in the systematic review. The pooled prevalence of asymptomaticPlasmodiuminfection among enrolled participants in Southeast Asia, South Asia, and Western Asia was 5.8%, 9.4%, and 8.4%, respectively. The pooled proportion of asymptomaticPlasmodiuminfection among all parasitised individuals in Southeast Asia, South Asia, and Western Asia was 89.3%, 87.2%, and 64.8%, respectively. There was a low prevalence of asymptomaticPlasmodiuminfection, but there was a high proportion of asymptomaticPlasmodiuminfection per all parasitised individuals in different parts of Asia. These results may support and facilitate elimination and control programs for asymptomaticPlasmodiuminfection in Asia.
