Health officials in Kerala (a state on India's southwestern coast) have urged residents to stay vigilant against mosquito-borne diseases this summer, after Ernakulam district recorded 239 dengue cases and at least one malaria case in recent weeks. Authorities warn that water storage during dry months creates ideal mosquito breeding conditions, and that migrant labourers are particularly vulnerable due to a lack of structured screening — with some patients leaving before completing treatment. Officials are calling on households and businesses to observe regular "Dry Days" to eliminate standing water and reduce breeding sites.
