HCMCity (VNA) - The HCM City Preventive Health Centre is piloting theuse of thermal foggers to kill mosquitoes, replacing the ultra-low volume (UTL)cold fogger, as the number of Zika incidences continues to increase.
DrLe Hong Nga, head of the health centre, said the machines spray dense fog thatstays in the air and on plants longer than the UTL cold fogger machines.
However,the disadvantage of the dense thermal fogger is that the fog could impairdrivers’ vision. It could also activate fire alarms when sprayed insidebuildings.
Cityofficials said the thermal foggers were being used outside buildings only.
Thecity used the thermal foggers to spray the campuses of HCM City University ofSocial Sciences and Humanities in Thu Duc district, the College of Finance andCustoms in District 9, and the University of Transport and Communications inDistrict 2 on December 4.
Dormitoriesand university grounds are at high risk because of discarded water containersthat have favorable conditions for mosquitoes.
Asof December of 4, the number of Zika incidences in the city had increased to 94in 19 out of 24 districts. Of these, 12 were pregnant women.
Althoughthe centre has expanded the spraying of chemicals to kill mosquitoes, theMinistry of Health has urged households to clean their houses and neighbouringareas and get rid of containers of water, which could be home to mosquitolarvae.-VNA
