Vector-borne diseases are spreading says scientist

Madurai: Deforestation as well as new system of
irrigation, urbanisation and change in ecosystem has made
certain vector borne diseases spread to other areas from their
traditional ones, a renowned scientist said today.

Mosquitoes and other insects were changing their habitat
with new system of irrigation and cropping patterns and a new
variety of vector species was emerging, and hence there was a
long way to go in finding solution to control vector borne
diseases, Prof.R.C.Mahajan, emeritus scientist and consultant
for ICMR and Ministry of Public health, said.

Some insects that were exclusive to Jammu and Kashmir and
Uttarkhand were now seen in other places also.Previously
Dengue was restricted to some areas like Rajasthan. "Now we
have to focus on various areas for different types of
dengue," he said.

Similarly Chikungunya had spread to other areas and it was
not getting controlled despite various measure,as new vectors
were emerging, he said, inaugurating the fifth conference of
Arthropodology Scientists here.

He claimed that statistics regarding people affected by
malaria, which officially was 1.3 million, could not be
correct.As per unofficial statistics, number of people
affected by malaria was 10 to 15 times more than the official
figure, he claimed, adding, this was because people were
seeking assistance of private labs and taking treatment at
private hospitals.

Dr Anita Desai, Associate Professor, NIMHANS Bangalore,
said Virus-Vector competency and relationship was an important
study.A deep study into virus-vector interraction would help
control several diseases.
