- Malaria is a serious infection. It is common in tropical countries such as parts of Africa, Asia and South America. Malaria is a disease caused by a parasite called Plasmodium that lives in mosquitoes.

Is Malaria a parasite, virus, bacteria or fungi? Malaria refers to a disease caused by a number of different species of parasite that is transmitted through mosquito bites. It is characterised by a febrile illness in people that have been to a country with malaria.lthough four species of malaria parasites can infect humans and cause illness, only malaria caused by Plasmodium falciparum is potentially life-threatening. Malaria transmission occurs in large areas of Central and South America, sub-Saharan Africa, the Indian subcontinent, Southeast Asia, the Middle East, and Oceania.

History of malaria At the close of the 20th century, malaria remained endemic in more than 100 countries throughout the tropical and subtropical zones, including large areas of Central and South America, Hispaniola (Haiti and the Dominican Republic), Africa, the Middle East, the Indian subcontinent, Southeast Asia, and Oceania.Roman fever' refers to a particularly deadly strain of malaria that affected the Roman Campagna and the city of Rome throughout various epochs in history. An epidemic of Roman fever during the fifth century AD may have contributed to the fall of the Roman empire.

Types of Malaria Its spread is blamed on Anopheles, a type of mosquito which is usually found in the tropical and sub-tropical regions. When the culprit mosquito sinks its sting into a person’s skin, the malaria parasites are circulated in the blood resulting in malaria fever.

Frequently Asked Questions (FAQs) Four kinds of malaria parasites infect humans: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae. In addition, P. knowlesi, a type of malaria that naturally infects macaques in Southeast Asia, also infects humans, causing malaria that is transmitted from animal to human (zoonotic malaria).lobally, the World Health Organization estimates that in 2013, 198 million clinical cases of malaria occurred, and 500,000 people died of malaria, most of them children in Africa. Because malaria causes so much illness and death, the disease is a great drain on many national economies.

Malaria Malaria is a mosquito-borne infectious disease of humans and other animals caused by parasitic protozoans (a group of single-celled microorganism) belonging to the genus Plasmodium.he parasites travel to the liver where they mature and reproduce. Five species of Plasmodium can infect and be spread by humans. Most deaths are caused by P. falciparum because P. vivax, P. ovale, and P. malariae generally cause a milder form of malaria. The species P. knowlesi rarely causes disease in humans.

Malaria Facts Between 1957 and 2015, in the United States, 63 outbreaks of locally transmitted mosquito-borne malaria have occurred; in such outbreaks, local mosquitoes become infected by biting persons carrying malaria parasites (acquired in endemic areas) and then transmit malaria to local residents.

Cholera The disease is most common in places with poor sanitation, crowding, war, and famine. Common locations include parts of Africa, south Asia, and Latin America. If you are traveling to one of those areas, knowing the following cholera facts can help protect you and your family.

Causes Malaria is caused by the plasmodium parasite. The parasite can be spread to humans through the bites of infected mosquitoes. There are many different types of plasmodium parasite, but only five types cause malaria in humans.These are:1  Plasmodium falciparum – mainly found in Africa, it is the most common type of malaria parasite and is responsible for most malaria deaths worldwide. 2  Plasmodium vivax – mainly found in Asia and South America.he parasite can be spread to humans through the bites of infected mosquitoes.

- The most common forms of human malaria are caused by Plasmodium falciparum, P. vivax, P. knowlesi, and P. malariae. P. falciparum, common in sub-Saharan Africa, and P. knowlesi, common in Southeast Asia, are especially dangerous.lasmodium, commonly known as the malaria parasite, is a large genus of parasitic protozoa. As with some other genera of clinically important microorganisms, the genus name also yields a common noun; thus species of the genus are known as plasmodia.

- Of the 300 million to 500 million annual cases of malaria, 90 percent occur in sub-Saharan Africa. The World Health Organization (WHO) reports malaria is responsible for one in five deaths of African children under age 5 every year.

Malaria Malaria parasites belong to the genus Plasmodium (phylum Apicomplexa). In humans, malaria is caused by P. falciparum, P. malariae, P. ovale, P. vivax and P. knowlesi. Among those infected, P. falciparum is the most common species identified (~75%) followed by P. vivax (~20%).alaria causes symptoms that typically include fever, fatigue, vomiting, and headaches. In severe cases it can cause yellow skin, seizures, coma or death. The disease is transmitted by the biting of mosquitos, and the symptoms usually begin ten to fifteen days after being bitten.

Anopheles Anopheles gambiae is one of the best known, because of its predominant role in the transmission of the most dangerous malaria parasite species (to humans) – Plasmodium falciparum.he genus Anopheles belongs to a subfamily Anophelinae with three genera: Anopheles Meigen (nearly worldwide distribution), Bironella Theobald (Australia only) and Chagasia Cruz (Neotropics).

- Malaria is not endemic in South Africa, and does not pose a major health risk. According to the WHO's World Malaria Report 2010, only 4% of the population is at high risk of malaria and 6% at low risk, while 90% live in malaria-free areas.Almost all cases are caused by Plasmodium falciparum.egislation. The National Health Act, 61 of 2003, provides a framework for a single health system for South Africa. The Act provides for a number of basic health care rights, including the right to emergency treatment and the right to participate in decisions regarding one's health.

Anopheles Mosquitoes Malaria is transmitted by different Anopheles species, depending on the region and the environment. Anophelines that can transmit malaria are found not only in malaria-endemic areas, but also in areas where malaria has been eliminated. The latter areas are thus constantly at risk of re-introduction of the disease.arvae of Anopheles mosquitoes have been found in fresh-or salt-water marshes, mangrove swamps, rice fields, grassy ditches, the edges of streams and rivers, and small, temporary rain pools. Many species prefer habitats with vegetation. Others prefer habitats that have none.

Measuring the Global Burden of Disease Malaria is a leading cause of the disease burden in areas from West Africa to Madagascar where malaria is hyperendemic (defined as parasitemia in >50% of the population) or mesoendemic (defined as parasitemia in 10 to 50% of the population).

Malaria Symptoms and Causes Because the malaria parasite is found in red blood cells of an infected person, malaria can also be transmitted through blood transfusion, organ transplant, or the shared use of needles or syringes contaminated with blood.

Types of Malaria This is the rarest of all the malaria types and is mostly found in Ghana, Liberia, Nigeria and the tropical West African region. Plasmodium ovale reoccurs in some cases because the parasite can rest in the liver of a patient for a few months to 4 years after getting infected by the mosquito carrying malaria.
