The National Research Institute of Health has found that three to four out of 100 mosquitoes collected at mountains near residential areas in Seoul are Asian tiger mosquitoes that can transmit the Zika virus and dengue fever.
 
The institute under the Centers for Disease Control and Prevention said Wednesday that out of 54-thousand-685 mosquitoes gathered at parks and mountains in Seoul, one-thousand-995, or three-point-four percent, were found to be Asian tiger mosquitoes.
 
The institute said that the rate is relatively higher than in actuality, as the latest test was carried out with the purpose of collecting Asian tiger mosquitoes.
 
Out of the collected Asian tiger mosquitoes, 90 were found to have sucked blood. Out of that total, 55 had fed on the blood of humans and nine the blood of mammals.
