At least 29 dengue patients have been hospitalised across the country in the last 24 hours, till 8:00am yesterday.

With the new cases, three of them outside Dhaka, the total number of dengue cases has risen to 864, according to Directorate General of Health Services (DGHS).

A total of 109 patients are still undergoing treatment; 754 patients have been released from hospitals, and one has died so far.

Warning city corporations of a major outbreak this year, experts suggested the corporations take extensive measures immediately to control Aedes mosquitoes.

Clear, stagnant water, the breeding ground for Aedes mosquitoes, at under-construction buildings is abundant this time around. The scenario came to light after DGHS conducted a pre-monsoon survey between March 23 and April 4.

The survey found three Dhaka South City Corporation wards to be at "high risk" and 10 at "medium risk" of an outbreak. Nine wards in Dhaka North City Corporation are at "medium risk".
