Key Facts
The Kerala government has announced the creation of a calendar to map seasonal and regional patterns of disease outbreaks. Health Minister K. Muraleedharan stated that Nipah cases repeatedly occur in the Perambra region of Kozhikode between May and September. Interestingly, some districts like Palakkad have reported no Shigella cases so far.
Details of the Outbreak Calendar
Speaking at a press conference on June 16, 2026, Muraleedharan noted that disease patterns vary but many viruses follow seasonal trends. Vector-borne diseases (dengue, malaria, chikungunya) and water-borne diseases (cholera, typhoid) are common in summer and monsoon. The reasons for these patterns remain unclear and are a key research area.
Experts believe the calendar will enhance predictive accuracy and help calibrate prevention and response. The government has also set up district-level monitoring cells and a high-power committee headed by Dr. S S Lal, with Sharmila Mary Joseph as coordinator.
Impact on Public Health
The Animal Husbandry department will assist in preventing zoonotic diseases. The Food Safety Inspectorate and Local Bodies will collaborate for a robust epidemic response. The committee will include doctors from private and government sectors, but its role is advisory only.
Muraleedharan denied accusations of hiding Nipah and Shigellosis figures. He confirmed that the Government Medical College in Kozhikode successfully treated a Nipah-positive patient. “There has been no Nipah death in Kerala. Out of the 38 persons tested for Nipah, only one was positive,” he said.
Shigella Outbreak Update
Kerala has recorded 146 Shigella cases since January 2026. The mortality rate is under control, with only five deaths, including a child. The minister blamed poor monsoon cleaning for the outbreak, citing that local body and assembly elections diverted official attention.
