Dengue fever cases on the rise in Chennai, India

The Chennai Corporation, the civic body that governs the city of Chennai, India, has reported an additional 15 cases of dengue this month, bringing the total to 130 cases this year.

The number of cases represents the highest total for the city since January 2008 and May 2008. Officials have attempted to counter the rising number of cases with intensified anti-mosquito fogging operations, the Times of India reports.

"The spread of dengue and malaria in summer is rare as the mosquito density is low due to absence of water stagnation," a senior corporation health official said, according to the Times of India. "But this year, it is higher than previous years."

Officials are checking many areas for conditions conducive to the breeding of mosquitoes, such as people storing waters in containers.

"We have deployed more staff for fogging operations especially in Royapuram, Anna Nagar and Tondiarpet," the official said, according to the Times of India. "If we find a case in any locality, all preventive measures will be taken. Recently, we conducted a similar drive in Kalakshetra Colony."

Passengers entering Chennai from southern districts such as Madurai, Virudhunagar and Tirunelveli are being screened at transportation terminals throughout the city. Officials want to ensure that the virus does not spread from southern district passengers.
