Malaria occurs mostly in poor, tropical and subtropical areas of the world. Africa is the most affected due to a combination of factors: A very efficient mosquito (Anopheles gambiae complex) is responsible for high transmission.
How common is malaria in Africa?
Most were in the WHO African Region, with an estimated 200 million cases, or 92% of global cases. In 2017, five countries accounted for nearly half of all malaria cases worldwide. Four of these were in Africa: Nigeria (25%), the Democratic Republic of the Congo (11%), Mozambique (5%), and Uganda (4%).
Where is malaria most common in Africa?
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.
What countries in Africa have malaria?
In 2019, six African countries accounted for 50% of all malaria cases globally: Nigeria (23%), the Democratic Republic of the Congo (11%), United Republic of Tanzania (5%), Niger (4%), Mozambique (4%) and Burkina Faso (4%).
What is Africa doing about malaria?
Insecticide-treated nets are the cornerstone of malaria prevention efforts in Africa. The report found that more than half (53%) of the population at risk in sub-Saharan Africa slept under a treated net in 2015, compared to 30% in 2010. Last month, WHO released the findings of a major 5-year evaluation in 5 countries.
Why are malaria cases so high 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.
What is the number one cause of death in Africa?
Leading 10 causes of death in Africa in 2019 (in deaths per 100,000 population)
|Characteristic||Deaths per 100,000 population|
|Ischaemic heart disease||429|
How long has malaria been a problem in Africa?
115 years of malaria in Africa.
How can we prevent malaria in Africa?
The main method of preventing malaria in high risk areas with one or more malaria cases per 1000 inhabitants per year is the use of insecticide-treated bed nets and the spraying of insecticide on the inside walls of houses.
Why is there no malaria in Europe?
Malaria was eradicated from Europe in the 1970s through a combination of insecticide spraying, drug therapy and environmental engineering. Since then, it has been mostly imported into the continent by international travellers and immigrants from endemic regions.
How many humans have died from malaria in history?
Over millennia, its victims have included Neolithic dwellers, early Chinese and Greeks, princes and paupers. In the 20th century alone, malaria claimed between 150 million and 300 million lives, accounting for 2 to 5 percent of all deaths (Carter and Mendis, 2002).
Who is most at risk for malaria?
People who are heavily exposed to the bites of mosquitoes infected with P. falciparum are most at risk of dying from malaria. People who have little or no immunity to malaria, such as young children and pregnant women or travelers coming from areas with no malaria, are more likely to become very sick and die.
Is malaria the biggest killer?
Malaria kills up to two million people per year, infecting 300 to 500 million more. The only infectious diseases that kill more people are tuberculosis and HIV/AIDS.
Is malaria a virus?
A: Malaria is not caused by a virus or bacteria. Malaria is caused by a parasite known as Plasmodium, which is normally spread through infected mosquitoes.
What are the prevention and control of malaria?
The main current measures are focused on reduction of the contact between mosquitoes and humans, the destruction of larvae by environmental management and the use of larvicides or mosquito larvae predators, and destruction of adult mosquitoes by indoor residual spraying and insecticide-treated bed nets.
