The prevalence and fight of malaria disease globally

First, more countries are accelerating towards elimination.

The prevalence and fight of malaria disease globally

Stepping up investments in malaria research and development is key to achieving the GTS targets. Deliveries of malaria commodities Insecticide-treated mosquito nets Between anda total of million insecticide-treated mosquito nets ITNs were reported by manufacturers as having been delivered globally.

Of this amount, million ITNs were delivered in sub-Saharan Africa, compared with million bednets in the preceding 3-year period — Rapid diagnostic tests An estimated million rapid diagnostic tests RDTs were delivered globally in The decrease was entirely in sub-Saharan Africa, where distributions dropped from million to million RDTs over the — period.

Artemisinin-based combination therapy An estimated million treatment courses of artemisinin-based combination therapy ACT were procured by countries inan increase from million in However, the proportion of households with sufficient nets i.

More people at risk of malaria in Africa are sleeping under an ITN. Fewer people at risk of malaria are being protected by indoor residual spraying IRSa prevention method that involves spraying the inside walls of dwellings with insecticides.

Globally, IRS protection declined from a peak of 5. In the WHO African Region, coverage dropped from 80 million people at risk in to 45 million in The declines in IRS coverage are occurring as countries change or rotate insecticides to more expensive chemicals.

However, about 13 million children who could have benefited from this intervention were not covered, mainly due to a lack of funding. SinceSMC has been recommended by WHO for children aged months living in areas of highly seasonal malaria transmission in this subregion. Diagnostic testing and treatment Accessing care Prompt diagnosis and treatment is the most effective means of preventing a mild case of malaria from developing into severe disease and death.

This includes public sector hospitals and clinics, formal private sector facilities and community health workers. More febrile children sought care in the public sector median: However, the surveys from Africa also indicate that a high proportion of febrile children did not receive medical attention median: Possible reasons include poor access to health-care providers or lack of awareness among caregivers.

Diagnosing malaria Among 17 national-level surveys completed in sub-Saharan Africa between andthe proportion of children with a fever who received a finger or a heel stick — suggesting that a malaria diagnostic test may have been performed — was greater in the public sector median: Testing of suspected cases in the public health system increased in most WHO regions since Children are more likely to be given ACTs if medical care is sought at public health facilities than in the private sector.

This approach promotes integrated management of common life-threatening conditions in children — malaria, pneumonia and diarrhoea — at health facility and community levels. In26 malaria-affected countries had iCCM policies in place, of which 24 had started implementing those policies.

Outside the WHO African Region, only a handful of countries in each of the other regions reported having such policies in place, though data on the level of implementation are unavailable for most countries.

Malaria surveillance systems Effective surveillance of malaria cases and deaths is essential for identifying the areas or population groups that are most affected by malaria, and for targeting resources for maximum impact.

A strong surveillance system requires high levels of access to care and case detection, and complete reporting by all health sectors, whether public or private. Rates vary within other WHO regions. This includes the high-burden countries of India and Nigeria.The mainstay of malaria diagnosis has been the microscopic examination of blood, utilizing blood films.

Although blood is the sample most frequently used to make a diagnosis, both saliva and urine have been investigated as alternative, less invasive specimens.

More recently, modern techniques utilizing antigen tests or polymerase .

Plasmodium falciparum incidence and number of deaths

Feb 16,  · Information on the prevalence of drug resistance and population spatial access to medicines is required to devise adequate clinical disease management strategies. The Mapping Malaria Risk in Africa (MARA) [ 17 ] collaboration was launched over a decade ago to help provide a geo-positioned series of malariometric data for Africa [ 18 ].

Chapter 8 - Malnutrition and micronutrient deficiencies Extent of the problem and its consequences. Chapter 7 provided a brief survey of the nutrient content of foods, the nutrient requirements of people at different stages of the life cycle, certain aspects of the African diet and food habits in relation to nutritional status.

The prevalence of this mosquito-borne disease in Africa costs at least $12 billion per year for treatment, reinforcing high poverty rates. UC Davis vector biologist Greg Lanzaro and research teams have joined the initiative to fight malaria in Africa. Under the global "health for all" strategy, WHO and its member states have resolved to place special emphasis on the developing countries.

The overall annual death rate from AIDS has fallen by 21% since , the most recent study in the Global Burden of Disease (GBD) series shows. However, while a number of countries with large HIV burdens have significantly reduced the epidemic’s death and disability toll, there is huge disparity.
