 The reported incidents of the zoonotic malaria plasmogym nolisi has significantly increased across Southeast Asia, threatening malaria elimination. Model-based infant methods were used to estimate the individual case reproductive number, Rc, 4p, nolisi, p, falciparum, and p. Vivek's human cases in Malaysia from 2012 to 2020. The best-fitting models for p, nolisi indicated subcritical transmission, Rc, 1, suggesting that the parasite remains the primarily zoonotic infection. In contrast, sustained transmission, Rc, 1, was estimated historically for both p. Falciparum and p, Vivek's, with declining Rc values observed over time, which indicates local elimination. These results suggest that non-zoonotic transmission of p, nolisi is highly unlikely, and that new approaches are necessary to control spillover risks. This article was authored by Kimberley M.
