India : Type 2 dengue virus predominant in Pune

Article via Times of India :

The dengue virus type 2 (DENV-2) is currently predominant among the three serotypes of the virus co-circulating in Pune, scientists at the city-based National Institute of Virology (NIV) have found.

DENV-2 causes severe infection. The scientists identified the serotype in a molecular study on 51 blood samples till October of dengue-infected patients from Pune. 

"Of these, DENV-2 was the causative agent in 35 cases, DENV-1 in 11 samples and DENV-3 in five samples. 

Therefore, DENV-2 is currently the predominant dengue strain. DENV-3 was predominant during July and August, but now it is DENV-2," said Cecilia Dayaraj, head of the dengue research group at the NIV.

As far as virulence of different serotypes is considered, it is believed that DENV-2 is associated more often with dengue haemorrhagic fever that occurs in secondary infections."
