Unseasonal January rainfall in Mumbai, Thane, and Palghar has prompted health authorities to issue alerts for potential increases in mosquito-borne diseases like Dengue, Malaria, and Chikungunya. Doctors warn that stagnant water in various urban locations provides breeding grounds for mosquitoes. The unusual weather, characterized by high humidity and fluctuating temperatures, is also contributing to a rise in seasonal ailments such as coughs, colds, and respiratory issues, exacerbated by existing air pollution levels. Health experts advise vigilance against these illnesses, typically more common during monsoon seasons.
