World Mosquito Day: August 20

The World Mosquito Day is observed every year on August 20 to raise awareness about the causes of malaria. The observance of the day seeks to created awareness to prevent and also to fundraise for research into the cure of malaria.

Background

World Mosquito Day also marks groundbreaking discovery of British doctor, Sir Ronald Ross when he had identified link between mosquitoes and malaria way back in in 1897. He had found that female Anopheles mosquitoes transmit malaria between humans. This discovery had laid foundations for scientists across world to better understand the deadly role of mosquitoes in disease transmission and come up with effective innovative interventions. Sir Ross is responsible for annual observance of World Mosquito Day, which was declared shortly after his discovery.

Mosquitoes

Mosquitoes are small, midge-like flies that constitute the family Culicidae. They have been around for over hundred million years now and diseases caused and spread by them leads to loss of several lives. There are over 3,500 species of mosquitoes have already been described. They are generally divided into two subfamilies, Anophelinae and Culicinae which in turn comprise some 43 genera.

Female mosquitoes are ectoparasites, whose tube-like mouthparts (called a proboscis) pierce hosts’ skin to consume blood for its own survival. Many species of mosquitoes are vectors of diseases. In passing from host to host, some transmit extremely harmful infections such as malaria, yellow fever, Chikungunya, West Nile virus, dengue fever, filariasis, Zika virus and other arboviruses.

Mosquitoes are most deadliest animal in the world, as around 6 million deaths every decade occur due to vector borne diseases transmitted by it. Deadliest among them are Malaria (transmitted through bites of infected female Anopheles mosquitoes), Dengue (transmitted by Aedes aegypti mosquito), Zika virus (also transmitted by Aedes mosquitoes), Chikungunya (spreads through bite of the Aedes aegypti mosquito) and Yellow fever (infected mosquitoes of Aedes species).

25 April: World Malaria Day

The World Malaria Day (WMD) is being observed every year on 25 April across the world to recognise the global efforts to control preventable vector borne disease malaria. It also seeks to highlight the need for continued investment and sustained political commitment for elimination and control of malaria.

The theme of 2018 WMD is “Ready to beat malaria“. The theme marks mportance of collective responsibility and commitment of global community in bringing together people on working towards making world free of malaria. It also puts exemplary progress achieved in tackling malaria under spotlight.

Background

The World Malaria Day (WMD) was established by the 60th session of World Health Assembly, a decision-making body of World Health Organization (WHO) in May 2007. It was established to provide understanding and education of malaria and also spread information on year-long intensified implementation of national malaria-control strategies. It is one of eight official global public health campaigns currently marked by the WHO.

Malaria

Malaria is mosquito-borne infectious disease most commonly transmitted through the bite of infected female Anopheles mosquito. It caused by parasitic protozoans (a group of single-celled microorganisms) belonging to Plasmodium type. After an infected mosquito bites human, parasites begin to multiply in person’s liver. It progresses to infect and destroy red blood cells (RBCs) in the body. Common symptoms of severe malaria include flu, fever and chills respiratory distress and deep breathing, abnormal bleeding, signs of anaemia and impaired consciousness. Malaria can be controlled by early diagnosis.
