Bengaluru: The State Health and Family Welfare Department as well as the Bruhat Bengaluru Mahanagara Palike (BBMP) insist that dengue cases are under control this year, but the figures show that in 2012 there has been a six-fold increase in the number of dengue positive cases and a four-fold increase in the number of dengue deaths compared to 2011. Both, the number of deaths as well as positive cases over the past four years, have been the highest in 2012.
From January 2012 to November 2012, Karnataka has recorded 3,640 dengue positive cases with 21 deaths. They were 405 dengue positive cases and five dengue deaths in 2011. In 2010 the corresponding figures were 2,285 dengue positive cases with seven dengue deaths and in 2009 there were 1,764 dengue positive cases and eight dengue deaths.
Dr Dhanyakumar, director, Karnataka Health and Family Welfare Department told Deccan Chronicle, "If anyone gets dengue then the person should be very careful as the fatality for them would be higher in the following year.?why?
The rise in numbers may be due to increasing breeding places for mosquitoes. In addition, with water shortage, most people tend to store water which becomes a breeding ground for dengue causing mosquitoes. About 25-30 per cent of the dengue burden in the State is from Bengaluru."
Following the increasing number of dengue positive cases from across the country, the Union Health Ministry recently implemented emergency treatment protocol for dengue positive patients.
As per the protocol two types of tests are recommended to diagnose dengue. The ELISA based antigen detection NS1 test detects cases from the first day of the disease.
Another ELISA based antibody detection IgM test detects dengue after five days of the disease. The IgM test kits are provided free of cost to diagnostics centres through the National Institute of Virology, Pune.
The NS1 test kits can be procured locally by State health departments for which funds have been provided under the National Vector Borne Disease Control Programme/National Rural Health Mission.
For augmenting diagnostic facilities, the number of sentinel surveillance hospitals with laboratory support has been increased to 347 across the country from 110 and they are linked with 14 apex referral laboratories with advanced diagnostic facilities for back up support.
