Kerala sees sharp rise in malaria cases as imported infections surge

What Happened

Four indigenous malaria cases and 974 imported cases were confirmed in Kerala as of 5 October 2026, marking a steep increase from previous years. The state recorded one death from local transmission and six deaths among imported patients this year.

Response

Health officials say the surge stems from a large mosquito population and a steady flow of travellers bringing the parasite from outside the state. "Over the past several years, the number of imported malaria cases has increased substantially. We need to strengthen surveillance measures, screening of migrants for the disease and ensuring intensive screening and testing for the disease in asymptomatic fever cases," said a senior health department official.

Measures

The department plans to distribute insecticide‑treated bed nets in households of Malappuram, Kozhikode and Kannur, where the highest indigenous case numbers were reported. Additional steps include intensified prevention activities to stop Kerala becoming a malaria‑endemic region.

Expert View

T.S. Anish, associate professor at Kerala University of Health Sciences, warned that the influx of migrant workers and climate change could push the disease into new districts. He noted that the state’s successful malaria‑free drive in the 1960s is being undermined by delayed detection and favourable local conditions.

Context

Kerala’s malaria rise follows a post‑2021 trend, after 252 imported cases were logged in that year. The situation highlights how increased travel and climate factors can revive diseases once thought controlled.
