This day highlights the importance to create awareness about mosquito-borne diseases like dengue, malaria and chikungunya and the efforts of healthcare officers, NGOs, and others in fighting diseases caused by mosquitoes.

Hence, the theme of World Mosquito Day 2021 is reaching the zero malaria target and other diseases where mosquitos are the vectors.


The method of transmission begins with introducing the virus into the human’s blood through the bite of an infected mosquito. Mosquito act as vectors for these diseases where the virus lives within the animal and transmits these viruses to infect humans through a bite. This transmission of diseases from animals to humans is a process called zoonosis.


The symptoms usually depend on the severity of the infection in a person. Some Malaria, Dengue, and Chikungunya signs have eye pain, muscle pain, bone pain, joint pain, headache, rising fever, rashes and nausea and vomiting. However, in the case of Dengue, the severity of the disease can also impact organs and platelet counts, causing organ failure, breathing difficulty, and internal bleeding.


Mosquito-borne diseases such as Malaria, Dengue, and Chikungunya are still prevalent in most parts of the country because of poor hygiene, rapid urbanization, and improper wastewater management. Below are the preventive measures that need to take into account to reduce the chances of getting bitten:

  • Use mosquito repellent
  • Use screening on windows and doors
  • Wear light colored, long-sleeved shirts and long pants
  • Avoid staying in dark, outdoor places during the hours when mosquito is active
  • Regularly empty and scrub, turn over, cover, or throw out any items that hold water like tires, planters, birdbaths and trash containers
