Which malaria is common in Africa?
Snow and Judy A. Omumbo. Plasmodium falciparum is the most common of the four human malaria parasites across much of Sub-Saharan Africa.
What is the most common disease in Africa?
Without access to medicines, Africans are susceptible to the three big killer diseases on the continent: malaria, tuberculosis and HIV/AIDS. Globally, 50% of children under five who die of pneumonia, diarrhoea, measles, HIV, tuberculosis and malaria are in Africa, according to the World Health Organisation (WHO).
How is Africa affected by malaria?
The World Health Organization (WHO) reports malaria is responsible for one in five deaths of African children under age 5 every year. Malaria takes its toll not only in lives lost, but also in medical costs, lost income, and reduced economic output.
What are the common diseases in malaria?
Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells. If not promptly treated, the infection can become severe and may cause kidney failure, seizures, mental confusion, coma, and death.
Why is malaria so common in Africa?
Africa is the most affected due to a combination of factors: A very efficient mosquito (Anopheles gambiae complex) is responsible for high transmission. The predominant parasite species is Plasmodium falciparum , which is the species that is most likely to cause severe malaria and death.
Why is malaria common Africa?
Why is Africa a malaria hotspot?
It may be surprising that most cases occur on the African continent. Malaria is common in the area south of the Sahara Desert (called sub-Saharan Africa) because the disease spreads almost entirely in poor regions with tropical and subtropical climates. The local weather allows for transmission to occur year round.
Why is Africa affected by malaria the most?
Where is malaria most common?
The highest transmission is found in Africa South of the Sahara and in parts of Oceania such as Papua New Guinea. In cooler regions, transmission will be less intense and more seasonal. There, P. vivax might be more prevalent because it is more tolerant of lower ambient temperatures.
When did malaria start in Africa?
The malaria parasites of humans are thought to have evolved in tropical Africa from 2.5 million to 30 million years ago (P. vivax, P. ovale, and P. malariae are among the oldest of the group).
What is the main cause of malaria?
Malaria is caused by a single-celled parasite of the genus plasmodium. The parasite is transmitted to humans most commonly through mosquito bites.
How can malaria be prevented in Africa?
Repellents should be applied to bare skin, and clothes can be treated. Other ways to avoid being bitten include burning mosquito coils or using heated insecticide mats in living and sleeping areas at night, and using insecticide-treated mosquito nets.
