Fifty-eight thousand eight hundred and thirty-four dengue cases—and around 80 dengue deaths—have been reported in the country by last Friday. During last year, only 58 dengue deaths had been reported in the country, the Epidemiology Unit said yesterday.According to the unit’s sources, 80 dengue deaths during a period of only 10 months is a cause for concern. Therefore, the public should be vigilant about mosquito breeding grounds and destroy them on a regular basis. At least 30 minutes per week should be allocated to clean such sites, they added.
