Understanding the Dengue Outbreak This Year

New Delhi: As Delhi battles the worst outbreak of dengue in five years, the government has asked people not to panic and has emphasised that 99.79 per cent people with dengue have completely recovered. Doctors and experts answered some frequently asked questions:

NDTV: Is it unusual that this year, type 2 and type 4 of the dengue virus are more common?

Dr Lalit Dar, Virologist, Department of Microbiology, AIIMS: There are four serotypes of dengue 1, 2,3,4 and all are present in Delhi.

Every three or four years, one type starts to dominate, it is not unusual...We have found dengue 4 this year, it is low, but it is there and this could be a reason for the increase (in number of cases).

NDTV: Is there a fifth new strain of the dengue virus that is tormenting Delhi?
