an essay about malaria

Overview. Malaria is a life-threatening disease spread to humans by some types of mosquitoes. It is mostly found in tropical countries. It is preventable and curable. The infection is caused by a parasite and does not spread from person to person. Symptoms can be mild or life-threatening. Mild symptoms are fever, chills and headache.

1. Introduction. Malaria affected an estimated 219 million people causing 435,000 deaths in 2017 globally. This burden of morbidity and mortality is a result of more than a century of global effort and research aimed at improving the prevention, diagnosis, and treatment of malaria [].Malaria is the most common disease in Africa and some countries in Asia with the highest number of indigenous ...

Headache and muscle aches. Fatigue. Chest pain, breathing problems and cough. Diarrhea, nausea and vomiting. As malaria gets worse, it can cause anemia and jaundice (yellowing of the skin and whites of the eyes). The most severe form of malaria, which may progress to a coma, is known as cerebral malaria.

Unlike other dangerous creatures, mosquitoes do their deadly work by spreading diseases - one of the worst of these is malaria. Malaria is an infectious disease caused by a parasite, called Plasmodium that invades red blood cells and liver cells. The parasites are transferred to humans by the bite of an infected Anopheles mosquito.

The outlook for malaria control is grim. The disease, caused by mosquito-borne parasites, is present in 102 countries and is responsible for over 100 million clinical cases and 1 to 2 million deaths each year. Over the past two decades, efforts to control malaria have met with less and less success. In many regions where malaria transmission had been almost eliminated, the disease has made a ...

malaria, serious relapsing infection in humans, characterized by periodic attacks of chills and fever, anemia, splenomegaly (enlargement of the spleen), and often fatal complications. It is caused by one-celled parasites of the genus Plasmodium that are transmitted to humans by the bite of Anopheles mosquitoes.Malaria can occur in temperate regions, but it is most common in the tropics and ...

Malaria is a treatable disease. Artemisinin-based combination therapies (ACTs) are the most effective antimalarial medicines available today and the mainstay of recommended treatment for Plasmodium falciparum malaria, the deadliest malaria parasite globally. ACTs combine 2 active pharmaceuticals with different mechanisms of action, including derivates of artemisinin extracted from the plant ...

Symptoms can resemble those of flu and can typically last 6-10 hours and recur every second day. However, some strains of the parasite can have a longer cycle or cause mixed symptoms. Overall ...

This documentary video discusses the epidemiology of malaria; strategies for prevention, including vector control and vaccines; and the pipeline of promising new drugs for the fight to eliminate ma...

Introduction. Malaria is named after the Italian term "mal'aria", which means "bad air" to represent the association of the disease with marshy areas. 1 It is an endemic vector-borne parasitic disease caused by protozoan parasites of the genus Plasmodium in tropical and subtropical regions worldwide. 2 Plasmodium consists of over 200 species, infecting mammals, birds, and reptiles ...

National malaria control programmes need to take special measures to protect these population groups from malaria infection, taking into consideration their specific circumstances. Treatment Malaria is a preventable and treatable disease. Early diagnosis and treatment of malaria reduces disease and prevents deaths, and also contributes to ...

Malaria is resurging in many African and South American countries, exacerbated by COVID-19-related health service disruption. In 2021, there were an estimated 247 million malaria cases and 619 000 deaths in 84 endemic countries. Plasmodium falciparum strains partly resistant to artemisinins are entrenched in the Greater Mekong region and have emerged in Africa, while Anopheles mosquito vectors ...

The World Malaria Report, released in December 2021, reflects the unique challenges currently facing the global malaria community. The report showed the devastating toll of malaria, with an estimated 627,000 people losing their lives to the disease in 2020. The improved methodological approach used for calculating cause of death for young children revealed a systematic underestimation of ...

Malaria has plagued humans for millennia and has led to an unimaginable loss of life. Malaria has also had an important role in the geopolitics and evolutionary history of humans. The malaria ...

Essays on Malaria, Environment and Society. The body of work presented here seeks to illuminate the complex relationship between human society, development, and environment for the case of malaria. While malaria profoundly affects human society and prospects for prosperity, public health measures and anthropogenic environmental change alter the ...

INTRODUCTION. Malaria is transmitted throughout most of the tropics; ongoing transmission occurs in 84 countries and territories [].In 2023, the World Health Organization (WHO) reported 247 million cases (up from 245 million in 2020) and 619 thousand deaths (down from 625,000 in 2020) due to malaria [].The annual number of malaria cases decreased steadily between 2000 and 2015 but thereafter ...

Essay on Malaria Malaria is a life-threatening disease caused by parasites of the genus Plasmodium, transmitted to humans through the bites of infected female Anopheles mosquitoes. Despite significant global efforts to control and eliminate malaria, it remains a major public health issue, particularly in sub-Saharan Africa and parts of Asia. This essay explores the causes, symptoms, impact ...

This disease is malaria. Nearly 40 percent of the world's population lives in areas that are effected by the disease. Malaria is a serious, infectious disease spread by certain mosquitoes. It is caused by infection with the Plasmodium genus of the protozoan parasite. More than one hundred species of this parasite exist.

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. Most cases were reported in children under the age of 5 years (67%) and in pregnant women, mainly in sub-Saharan Africa (94%) and Southeast Asia (3%).

In addition to morbidity and mortality, infectious diseases are bidirectionally linked to poverty. Malaria has micro- and macroeconomic consequences for affected regions: decreased income, tourism, and foreign investment and increased health expenditures [6]. In contrast, areas that control malaria realize higher life expectancies and economic ...

Malaria is caused by Plasmodium parasites, which are spread, to people through bites of infected Anopheles mosquitoes, which are referred to as malaria vectors known to bite primarily between dusk and dawn. Four parasite species that result in malaria in humans are the following: (4) Plasmodium ovale.

Malaria killed over 600,000 people in 2022, a death toll that has not improved since 2015. Additionally, parasites and mosquitoes resistant to existing interventions are spreading across Africa ...

Malaria parasites that can shrug off the effects of the critical drug artemisinin are now well-established in East Africa. Resistance levels have soared in some areas from fewer than 1% to more ...

"Moreover, after the campaign, we found that self-reported malaria incidents in households at lower risk went down by about 43 percent, but we didn't find any effect among households living in these non-solid dwellings that are more at risk of malaria," says Donati. "So we face very strong and significant heterogeneous effects across ...

For decades, insecticide-treated bed nets and indoor insecticide spraying regimens have been important - and widely successful - treatments against mosquitoes that transmit malaria, a dangerous global disease. Yet these treatments also - for a time - suppressed undesirable household insects like bed bugs, cockroaches and flies.

A meta-analysis found that pyriproxyfen (PPF) long-lasting insecticidal nets (LLINs) effectively reduce indoor vector density by 1%, entomological inoculation rate by 7%, and sporozoite rate of malaria parasites by 15% compared to pyrethroid-only LLINs in Africa, despite no significant difference in malaria infection, case incidence, and anemia ...

Similarly, deaths due to malaria increased in 2020 with respect to 2019, but then declined slightly in 2021. The excess in cases and deaths in these years have been attributed mainly to the disruption to prevention and control strategies attributed to the COVID-19 pandemic. The epidemiology of imported malaria is also changing.
