" KATHMANDU : Two cases of dengue fever have been found in Kathmandu for the first time. Dengue is caused by dengue virus (DenV), a mosquito-borne flavivirus. It is transmitted by Aedes mosquitos.
"This is the first discovery of dengue fever in the Kathmandu Valley even though the disease was detected in the Tarai and inner-Tarai districts some five years ago," according Sukraraj Tropical and Infectious Disease Hospital, Teku.
"Aedes mosquitos are found in cold water, freeze, cooler houses and other cold places and rich people are vulnerable to dengue fever," said Dr Bashu Dev Pandey at Teku Hospital on Monday.
He said the disease is communicable from one person to another and its symptoms are high fever, bleeding and unconsciousness. "If an infected person is not treated on time, the patient may die," he said.
Aedes mosquitos also breed on water collections in artificial containers such as plastic cups, used tires, broken bottles, flower pots, etc. Dr Pandey advised people to keep their freezes and cooler houses clean and treated water to remain safe from the disease."
