How Mosquitoes Spread the Diseases

Mosquitoes are some of the most harmful insects on the planet because they are capable of carrying and transmitting diseases that are responsible for millions of annual deaths. Diseases spread by mosquitoes include malaria, yellow fever, dengue, chikungunya, West Nile virus, filariasis, and zika. Over half of the world’s population resides in areas where mosquito species that transmit these diseases are present.


How Mosquitoes Spread the Diseases


The process through which a mosquito gets infected with a disease-causing agent is complex. It starts with a female adult mosquito feeding on blood from an infected host. The mosquito swallows and digests the pathogen, which then seeps into its body through the digestive system. As the pathogens circulate in the mosquito’s body, they infect its salivary glands and other organs. The entire process can take place in weeks and is faster in higher temperatures. When the insect bites another individual, they will pass on the disease-causing agent and infect them with one of the several mosquito diseases.


Precautions Against Mosquitoes

If mosquitoes are endemic to your area, you should take the following precautions to keep them from biting and infecting you with disease:



  • Limit activities that require you to be out in the open at night when mosquitoes are most active.


  • Wear long-sleeved tops, long pants and socks between dusk and dawn to minimize the amount of skin exposed to mosquito bites.


  • Use treated mosquito nets at night as you sleep.


  • Clear bushes and any stagnant waters around your premises.


  • Use insect repellents on exposed skin in areas with mosquitoes, especially at night.


  • Utilize insecticides or spatial that are commercially available.


Taking all these precautions is essential, especially if you live in or intend to visit a tropical country known to have cases of mosquito diseases. Some of the diseases transmitted by mosquitoes, such as malaria, can be fatal, particularly among children. For this reason, always ensure you and your loved ones always apply these precautions when necessary.
