Dengue mosquito spray medicine is toxic to people?

Director of Hanoi Preventive Medicine Center said that 7% to 10% of households in the area did not cooperate when the preventive medicine team of the ward came to spray insecticide to kill dengue fever because they thought that Medications harmful to human health.

In response to people's doubts about the harmful effects of mosquito sprays on human health, the PV recorded the opinions of medical experts on this issue.

According to Mr. Tran Dac Phu, Director of the Department of Preventive Medicine of the Ministry of Health, if there are neighbors or people living in the residential area with dengue fever, then your home is in the outbreak. Ward and commune health stations will visit each house to spray mosquitoes for the whole area.

Mr. Phu affirmed that the current spraying insecticide used by the Ministry of Health to stamp out dengue fever in residential clusters is not toxic to human health. Existing insecticidal products include three groups: organochlorine-based groups, groups of organic phosphorus and Pyrethrine-based groups. The current insecticide used by the Ministry of Health is the newest generation of Pyrethrine , the leading drug and tested in all 3 regions of Vietnam for safe results. Currently countries around the world are also using this drug.

Mr. Nguyen Nhat Cam, Director of Hanoi Preventive Medicine Center, said that spraying against dengue fever is a small volume of space spraying with very small amount of chemicals in the form of mist but effective multi. Only a few hours after spraying, the amount of chemicals will diffuse in the space so the fear of health-related drugs is an unwarranted concern.

Mosquito repellent is currently used by the Ministry of Health to stamp out dengue fever in residential clusters, which is not toxic to human health .

After spraying, people just wait for the dry medicine for about 30 minutes to enter the house safely . For some people with respiratory illnesses or young children who are easily irritated (may cough), it is advisable to avoid going outside for 2 to 3 hours and then entering the home.

He also said that on the other hand, with the characteristic of only a few hours after spraying, this amount of chemicals will diffuse in the space as mentioned above, so the spray can only kill the mosquitoes that are infected with the virus. hemorrhage at that time, not sustained, forever. When the amount of chemicals has been exhausted in the air, if the surrounding environment or other households still exist dengue mosquitoes, the mosquito can continue to fly into the house, burning people. And so, the risk of dengue still occurs.

He noted that many people think that families have sprayed insecticide chemicals a while ago and when the area is epidemic, health workers continue to spray the spray, it will not be necessary. That is a misconception. Because if only one household sprayed, consciously killed the stubble, the larvae but the hamlet still left many waste stagnant water, the other households did not have the awareness of disease prevention. from house to house and transmission.

Mr. An once again noted that the medicine that the epidemic team of preventive medicine ward and commune will come to the house will be free and people do not have to pay any money when spraying against the epidemic. If there is no anti-epidemic chemical spray, where is the health sector's anti-epidemic force? People see this phenomenon to immediately report to the authorities immediately.

He also said that there are a number of people who come to households to offer mosquito spraying and may commit frauds and robbery. However, this drug is not sure about the quality, technique, dosage, direction, spraying direction, mixing chemicals, handling after spraying according to the regulations of the Ministry of Health. If people need spraying, they should go to commune and ward health stations or call the hotlines of the Health Departments for full advice and avoid being abused.
