For clinically suspected cases of chikungunya, the highest count was 20,411 in Karnataka, down from 32,831 cases in 2017. Karnataka is followed by Gujarat (10,601), Maharashtra (9,884), Jharkhand (3,405) and Madhya Pradesh (3,211).
In its reply, the Health Ministry noted that dengue and chikungunya are outbreak-prone diseases, and therefore their numbers vary from state to state and from time to time.

Therefore, a year-on-year increase in the number of cases for a particular state depends on when an outbreak happens, it said.
