Tokyo has a brush with Denggo about four years ago but contained the disease by destroying all breeding spots in the area where the vector-based disease has infected 300 people, a scientist with the National Institute of Infectious Diseases in Japan said.

YoshiFumi Takeda, who was in Calcutta to participate in a conference on Saturday, said the authorities held a rigid vigilante and disrupted all possible breeding grounds every year, although there was no drop from Deng.

But in Calcutta, where some people every year, the authorities have always struggled to contain the disease.

Takeda has the secretion of severe monitoring and destruction of breeding spots. "A mosquito can not fly endlessly, so we targeted the region where the patients come from. We killed the mosquitoes and destroyed the breeding sites."

The World Health Organization (WHO) website says the female Aedes Aegypti Mosar, the primary transmitter of Deng in India, flying 400m on average.

In Japan, the Oedes albopictus mosquito is the Deng switches, but this mosquito is also a limited flying range. Takeda has the authorities used the limited flying range to their advantage. Dengue is reported in Japan after 70 years, according to the WHOIS website.

"We decided to kill the mosquitoes as well as breeding spots and we managed to do that," Takeda said.

The Calcutta Municipal Corporation also follows a similar process – on pen and paper. Vector-control workers are supposed to scan 100m around a house, which has a Deng sole. The area is supposed to be fumigated and breeding sites destroyed so that adult mosquitoes carrying the virus can not breed and pass on the virus to the next generation, a health-care official said.

At least 2500 people were infected with the Dengg virus in Calcutta this year.

Calchuta population density may be a reason for the CMC failing to do what the authorities in Japan have. "Houses are so close to each other, and the risk of being a hurdle with Denggo in Calcutta is very difficult to track and destroy all breeding sites here," Takeda said.
