How much of the human population is subject to malaria?
At the turn of the 21st century, therefore, we estimate that 48% of the global population remain exposed to the risk of malaria, a situation that has deteriorated since the early 1990s and a figure substantially higher than the 40% widely cited.
What is the epidemiology of malaria?
Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. It is preventable and curable. In 2020, there were an estimated 241 million cases of malaria worldwide. The estimated number of malaria deaths stood at 627 000 in 2020.
Where are most cases of malaria and who is most affected by it?
Africa is the world region that is most affected by malaria: in 2019, 96% of global deaths from malaria occurred on the African continent. But Africa is also the world region that has achieved most progress: since 2000, deaths have fallen significantly.
Is malaria a pandemic or epidemic?
Yet despite the fact that HIV and AIDS, tuberculosis, and malaria still kill millions of people each year across multiple countries and regions, these diseases are no longer talked about as pandemics, but are generally called epidemics, or endemic diseases.
Why is there no malaria in the US?
Malaria transmission in the United States was eliminated in the early 1950s through the use of insecticides, drainage ditches and the incredible power of window screens. But the mosquito-borne disease has staged a comeback in American hospitals as travelers return from parts of the world where malaria runs rampant.
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.
Is malaria a global health issue?
Malaria remains one of the deadliest infectious diseases worldwide. According to the World Malaria report 2020 released by WHO in November last year, 229 million cases and 409 000 deaths occurred from malaria in 2019.

Disease Burden
- The new cause-of-death methodology was applied to 32 countries in sub-Saharan Africa that shoulder about 93% of all malaria deaths globally. Applying the methodology revealed that malaria has taken a considerably higher toll on African children every year since 2000 than previously thought. The WHO African Region continues to carry a disproportiona...
Prevention
- Over the last 2 decades, expanded access to WHO-recommended malaria prevention tools and strategies – including effective vector control and the use of preventive antimalarial drugs – has had a major impact in reducing the global burden of this disease.
Case Management
- Early diagnosis and treatment of malaria reduces disease, prevents deaths and contributes to reducing transmission. WHO recommends that all suspected cases of malaria be confirmed using parasite-based diagnostic testing(through either microscopy or a rapid diagnostic test). Diagnostic testing enables health providers to swiftly distinguish between malarial and non-mal…
Elimination
- Malaria elimination is defined as the interruption of local transmission of a specified malaria parasite species in a defined geographical area as a result of deliberate activities. Continued measures to prevent re-establishment of transmission are required. In 2020, 26 countries reported fewer than 100 indigenous cases of the disease, up from 6 countries in 2000. Countries that hav…
Surveillance
- Malaria surveillance is the continuous and systematic collection, analysis and interpretation of malaria-related data, and the use of that data in the planning, implementation and evaluation of public health practice. Improved surveillance of malaria cases and deaths helps ministries of health determine which areas or population groups are most affected and enables countries to …
Who Response
- The WHO Global technical strategy for malaria 2016–2030, updated in 2021, provides a technical framework for all malaria-endemic countries. It is intended to guide and support regional and country programmes as they work towards malaria control and elimination. The strategy sets ambitious but achievable global targets, including: 1. reducing malaria case incidence by at leas…
