Abstract
|
|
|
In order to monitoring of Japanese encephalitis (JE) outbreak in South Korea, vector mosquitoes were collected by operating black light trap in twice a week at nine locations across the whole country from April to October 2020. The number of individuals collected per trap per day was calculated and analyzed for comparison. In 2020 collecting period, 10,635 mosquitoes were collected, which marked a 53.7% decrease from 2019 when 22,962 mosquitoes were collected. Among the total mosquitoes density, the occurrence rate of vector mosquitoes density was 16.5% in 2020; a 8.5% increase from 2019. Due to the low average temperature and large number of precipitation days and amounts, the total number of
mosquitoes decreased in the summer months of 2020. In addition, large amounts of precipitation in late summer and warmer temperature in early autumn contributed to the creation of suitable habitats for vector mosquito larvae growth. Thus, the rate of occurrence of vector mosquitoes increased from 2019. 2020 JE watch and warning were issued on March 26 and July 23, respectively, and we need continuously monitoring and data analysis in high JE outbreak regions.
