THIRUVANANTHAPURAM: The mosquito index has exceeded limits in many parts of the state capital setting alarm bells ringing for the health authorities.
Several hot spots have been identified in the corporation limits and across the districts stressing the need for extensive and regular fogging activities.

The district medical office has given strict direction to the city corporation to step up measures. “Every week we exchange the vector index and hot spots identified in the corporation area,” the official added....
