From February 2002 1 to February 29th,1,during these eight months, 2539 people in Nepal * * * were infected with dengue virus. There are 77 counties in Nepal, 70 of which have seen the spread of dengue fever, and the number of hospitalized dengue patients is still increasing. As we all know, Nepal's infrastructure construction is relatively backward, the medical and health system is not perfect, and the health environment is not very good, which is very prone to infectious diseases such as dengue fever. At present, in order to cope with the spreading trend of dengue fever, some areas in Nepal have begun to clean up cities, especially drainage systems, and spray drugs to carry out mosquito control operations.

Dengue fever is a viral infectious disease mainly transmitted by the bite of Aedes mosquitoes, which mainly occurs in tropical and subtropical regions. On this basis, as long as the number of Aedes mosquitoes is greatly reduced and their reproduction is reduced, the spread of dengue fever can be effectively blocked. Because mosquitoes mainly rely on water to lay eggs and reproduce, keeping the city's water source clean, keeping drinking water clean and minimizing urban water accumulation can greatly reduce the spread of dengue fever.

The best way to eliminate infectious diseases is to deal with them at the source. Because of this, some areas in Nepal began to transform the urban drainage system to make the water in the drainage system as mobile as possible. At the same time, it is necessary to clean up the accumulated water on the road. Dirty water on the road is also the main place where mosquitoes lay eggs. Besides, the environment should be kept clean. Through these means, we can ensure that the source of dengue infection is reduced.

In addition to controlling the source of infection, some areas in Nepal have also sprayed drugs in cities and carried out anti-mosquito operations. This cut off the spread of dengue fever from the route of transmission. Once mosquitoes carrying dengue virus are eliminated in large numbers, the number of dengue patients will be greatly reduced. Finally, we can strengthen the treatment of dengue patients and ensure their life safety.
