He shared that the risk of dengue fever continues till the month of Kartik (mid-November) as the mosquitoes transmitting the disease to humans remain active up to that period. 


After that, the dengue-transmitting mosquitoes will vanish gradually as the temperature dips. 


So far, all districts except Humla have reported dengue and the cases exceeded 27,000 with 11 deaths this year. 


Kaski district has the highest number of dengue cases with 7,080 while the number of dengue patients is 5,748 in the Kathmandu Valley.


The government has launched a “Larva Search and Destroy” campaign every Friday to prevent the spread of dengue. 


The mosquito-borne disease is transmitted by Aedes-aegypti and Aedes alobopictus mosquitoes. The mosquitoes of the species are active in the morning and evening time and breed in pooled water. It is said that the white blood cell count goes down in the critical cases of dengue. 


The mosque-transmitted disease which was mostly found in the country’s Terai-Madhesh in the past has now spread across the country including even in the mountainous areas.
