What are the hazards of mosquitoes?

Mosquitoes are a serious public health problem in most parts of the world. It is estimated that about 700 million people are infected by mosquitoes every year, and one in 17 people dies from mosquito-borne diseases. Especially in the tropics, many infectious diseases are often transmitted to humans by mosquitoes.

According to a survey conducted by the Department of Health in 1935, in areas where miasma is prevalent, 50% of residents have malaria parasites in their blood and 72% suffer from falciparum malaria.

2. Epidemic encephalitis B: this is an acute infectious disease caused by a viral virus, and it is also transmitted by mosquitoes. This disease is also called Japanese encephalitis. It is commonly called encephalitis. Patients have fever, headache, vomiting, dyspnea, coma, coma and other phenomena. There are no special drugs in treatment, so the fatality rate is quite high.

3. Transmission of filariasis: the transmission vector of filariasis is more than 30 species of mosquitoes belonging to 4 genera, such as Anopheles sinensis, Anopheles minimus, Culex pipiens pallens and Culex pipiens quinquefasciatus. Human is the only final host and is generally susceptible.

◆ then carefully check whether there are small holes and seams that mosquitoes can drill into, stick them with adhesive tape and plug them with sponge.

③ phototaxis prevention and control: LED mosquito lamp appeared on the market, using the phototaxis principle of mosquito lamp, combined with the purple light of 365NM wavelength to induce mosquitoes, which was attracted to the sealed room by the powerful extension under the light, and died of air-drying and dehydration. No chemicals, no open fire, no pollution, no irritating odor, no additives, no noise, no radiation, no harmful gases, efficient and energy-saving to achieve the purpose of killing mosquitoes.
