Kathmandu: Dengue infection which had significantly increased with the onset of rainfall has now slowed down.
The infection was intense so much that there were reports of the detections of above 5,000 dengue cases in a single week when the infection was at its peak. According to the Epidemiology and Infectious Division, Department of Health Services, there were 624 dengue cases in a single week (November 1-7). The total of 17,017 dengue cases was reported in October followed by 27,029 in September. However, the infection slowed down with the beginning of winter season, it has been said.
Division Director Dr Chumanlal Das said the infection has gone down since the past two weeks. The figure is expected to make a significant fall in the next two weeks, according to him. Shukraraj Tropical and Infectious Disease Hospital’s director Dr Manisha Rawal said now there are only nine dengue patients in the hospital and among them, three are receiving treatment at the Intensive Care Units while remaining six are in the general beds.
Winter season is not suitable for the breeding of mosquitoes causing dengue. So, the spread of the disease is likely to go down. In Nepal, the highest number of dengue cases was 50,263 since its first case in 2004. The infection was highest between mid-June and mid-October. The country reported no dengue cases in 2005 following its first case in 2004 and the infection reemerged in 2006 with the detection of 32.
The deaths toll from the infection this year so far was 54, the Division confirmed. According to Tribhuvan University Teaching Hospital’s information officer, Ram Bikram Adhikari, at present 20 patients are being treated for dengue at the hospital.
The World Health Organisation states dengue is a viral infection transmitted to humans through the bites of infected mosquitoes. The primary vectors that transmit the disease are Aedes aegypti mosquitoes and, to a lesser extent, Ae. albopictus.
