Over the past five years, Karnataka consistently recorded a very high number of acute diarrhoeal disease (ADD) and typhoid cases—both major water-borne illnesses. In fact, data analysed by the Union health ministry for 2021–25 puts Karnataka among the country’s significantly high-burden states, ranking third in typhoid and fifth in ADD. In 2021, the state reported 3.3 lakh ADD and 3021 typhoid cases. This dropped sharply in 2022 to 1.3 lakh ADD cases (a 61.1% decline from 2021) even as typhoid surged to 29,232 cases (an 867.4% increase). The number of cases largely rose later on. Meanwhile, leptospirosis (rat fever) also remained comparatively elevated, with 8697 cases reported over five years, averaging roughly 1739 cases annually. Source: https://timesofindia.indiatimes.com/
