Contain Dengue Transmission Risk

With the onset of monsoon, more cases of dengue have been reported across Nepal, posing a higher risk of this deadly mosquito-borne disease being transmitted as an epidemic. As the country is expected to witness more than average rainfall this monsoon, health authorities have already warned that there is a possibility that this virus disease may emerge as a serious public health concern. In pre-monsoon and rainy season, there are greater chances for the population of mosquito species carrying dengue virus to increase rapidly. Until some years in the past, dengue was a seasonal disease. But because of rapid urbanisation and global warming, dengue has begun posing a threat year-round. Modification in mosquito behaviour is another factor leading to an increased risk of dengue infection almost throughout the year.
