Why Is Malaria More In Africa Than Other Parts Of The World?
The debate about whether to create a WHO malaria base in only Africa has been raging since 1946.
The WHO started to take shape as a result of the publication of Barber’s book.
Russell wrote a foreword for the book in 1946 but didn’t mention Barber’s conclusions.
Instead, he described the book as an account of malaria work in different parts of the world.
The book, Russell said, should encourage us to unlearn common misconceptions and embrace simple truths.
Despite the fact that An. stephensi has only recently been detected in Ethiopia, it is still a significant threat to malaria control in the continent.
This mosquito prefers outdoor habitats where it can feed during the twilight hours.
Therefore, it is a threat to urban populations because it evades typical African mosquito survey methods.
The World Health Organization has issued a vector alert for Africa as a result of the invasion of An. stephensi.
To assess the climate sensitivity of An. stephensi, we used the Brinkoff City Population database for urban areas.
In Fig. 4, we identified malaria-endemic zones in Africa. We then calculated the distances of these cities to the malaria-endemic zones in Africa.
In the urban areas, we found the most suitable locations for larval An.
stephensi were urbanized. These sites typically suffer low malaria transmission.
The origin of Plasmodium falciparum is unknown, but its genetic structure is consistent with previous studies.
Among the continents, Africa has the highest level of genetic differentiation, followed by Asia and South America.
Geographic distance between populations increases with time, but not with geographic distance among African and Asian populations.
Hence, it is unlikely that the parasite originated in Africa.
The malaria epidemic has decreased dramatically in most African countries in the last few years.
Between 2000 and 2015, the number of malaria deaths among children was reduced in countries with low endemicity.
However, among persons aged fifteen years and older, the number of malaria deaths rose sharply, rising from 14.6% to 21.7%, respectively.
This trend continued after the study period, which was completed in 2015.
In some parts of Africa, such as Mauritania, P. vivax has been found in malaria cases.
The World Health Organization should take note of this finding as it has important implications for diagnosis, treatment, and malaria control in this area.
However, a number of specific detection methods have not yet been widely applied in this area. In other parts of the world, P. vivax is a relatively common cause of malaria.
Although the mosquito is the definitive host, humans are still an intermediate host.
Although seasonal variations have been observed in Africa, P. vivax is more common in sub-Saharan and tropical regions.
Despite the fact that there is no effective malaria vaccine for routine use, this disease remains one of the most common causes of morbidity and mortality in tropical areas.
Nevertheless, despite the lack of a specific malaria vaccine, precautionary measures should be taken to prevent infection in patients with the parasite.
A community-based approach to malaria prevention
Integrated community-based approaches to malaria prevention can be effective tools in reducing the burden of malaria.
For example, malaria chemoprophylaxis can be administered in conjunction with existing community-based malaria interventions, but a single strategy for such a roll-out is currently lacking.
Community case management, for instance, integrates childhood diarrhea, pneumonia, and malaria prevention, and utilizes existing CHWs to treat children during home visits.
This approach has improved ITN use and malaria treatment for children.
An important challenge in eliminating malaria remains to identify cases.
As malaria is more difficult to diagnose, the need for operational solutions is critical.
Community engagement is often overlooked in malaria control programs and is often confused with providing education, information, or communication.
This study sought to expand on the concept of CE for malaria prevention by studying a number of health and development programs.
The study’s manual analysis focused on key principles, methods, and results of community engagement.
Progress in fighting malaria
In Africa, the death rate from malaria is down dramatically.
Pneumonia now kills more children under five than malaria does.
But malaria still kills one child every two minutes. In some countries, like Algeria and Botswana, the disease has declined dramatically.
Countries like Cape Verde and Eritrea have also experienced a sharp decline in malaria cases.
Nigeria has remained the highest-risk country, where malaria kills approximately 100,000 people annually. Investing in prevention and treatment is crucial to fighting malaria.
RDTs were introduced in 2004, making them easy to distribute and use in rural areas.
In Ethiopia, 80% of the population lives in rural areas.
Health extension workers in rural communities conduct home-to-home outreach to reach families with basic curative and promotive services.
By distributing these RDTs and improving their reach, the malaria burden is reduced by an estimated 1.4 million lives each year.
