Speakers at a human chain have demanded that both the Dhaka city mayors step down from their posts if they cannot check mosquitos and the recent dengue outbreak in the capital.

The number of recorded dengue fever cases in May and June was more than five times that of the corresponding months of last year, and things are getting even worse.

Dhaka South City Corporation (DSCC) Mayor Sayeed Khokon says the infection rate of dengue fever is comparatively higher than the previous years.
