Amid reports of increased swarms of mosquitoes in some areas in Metro Manila, the Department of Health (DOH) recorded lower cases of dengue cases in the region this year.
Data from the DOH-National Epidemiology Center (NEC) said the dengue cases in the National Capital Region (NCR) from January to March 1 this year was 29.33-percent lower than those in the same period in 2013.
The DOH-NEC counted 1,294 dengue cases in Metro Manila from January to March 1, significantly lower than the 1,831 cases in the first three months of 2013.
Meanwhile, Pasig City, where residents especially in areas near the Pasig River complained about more mosquitoes flying to their communities, recorded 114 dengue cases year-to-date, which is 10.24 percent lower than last year.
On the other hand, 244 dengue cases were treated in Manila, where some areas were also reported to be invaded by mosquitoes. The number was also lower than the 289 cases in the city last year.
Fourteen out of the 17 cities and municipalities in the NCR listed posted declines in dengue cases this year, ranging from 10 percent to 70 percent DOH officials told the public that the mosquitoes recently infesting the region were not as dangerous as those carrying diseases like dengue, malaria and chikungunya.
The officials said they were mostly Culex or common household mosquitoes which, compared to the Aedes aegypti or the dengue-carrying mosquito, are bigger in size, fly at dawn or before dusk and lay eggs in stagnant dirty water. Their bite can cause only itchiness, and they have no ability to transmit common mosquito-borne diseases.
