World Mosquito Day

Don’t Get Bit on World Mosquito Day!

121 years ago on August 20th, Sir Ronald Ross discovered the link between mosquitoes and malaria. Today is World Mosquito Day. This day aims to raise awareness about the causes of malaria, how it can be prevented, and raise funds for research to find a cure for malaria.

Causes of Malaria

  • Malaria is a life-threatening disease that is typically transmitted through the bite of an infected mosquito.
  • There are four kinds of malaria parasites that can infect humans:
    • Plasmodium vivax
    • P. ovale
    • P. malariae
    • P. falciparum (causes a more severe form of the disease)
  • Malaria is transmitted through blood. For example:
    • An organ transplant
    • A transfusion

Symptoms of Malaria

Malaria symptoms typically develop within 10 to 28 days following the infection and include:

  • Shaking chills
  • High fever
  • Profuse sweating
  • Headache
  • Nausea
  • Vomiting
  • Abdominal pain
  • Diarrhea
  • Anemia
  • Muscle pain
  • Convulsions
  • Coma
  • Bloody stools

The CDC has an up-to-date map of where malaria can be found.

You can also search by country to see specific areas where malaria is especially common.

How it can be prevented

  • Unfortunately there is no vaccine available. However, if you are travelling to an area where malaria is common it is important to talk to your doctor. There are medications that can be prescribed to you to help prevent the disease.
  • If you live in an area where malaria is common please talk to your doctor about long term prevention. Some ideas include sleeping under a mosquito net or even using bug spray that contains DEET
