Malaria is a mosquito-borne disease caused by a parasite.
Malaria symptoms include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells. Infection with one type of malaria, Plasmodium falciparum, if not promptly treated, may cause kidney failure, seizures, mental confusion, coma, and death.
Each year 350 to 500 million cases of malaria occur world-wide, and over one million people die, most of them young children.
The Anopheles Malaria Mosquito.
Where malaria disease is found depends mainly on climatic factors such as temperature, humidity, and rainfall. The main areas where malaria disease is found are; Africa, Madagascar, India and South America. Malaria is transmitted in tropical and subtropical areas, where the host mosquito, of the genus Anopheles, is able to survive and multiply. There are approximately 430 Anopheles mosquito species, only 30 to 40 of which transmit the malaria parasite.
Only in areas where the malaria parasites can complete its growth cycle in the mosquitoes can humans be infected. There are four species of malaria parasite that can infect humans they are; Plasmodium falciparum, P. vivax, P. ovale, and P. malariae. The time required for development of the parasite in the mosquito (the extrinsic incubation period) ranges from 10 to 21 days,
Malaria is a very contagious parasite transmitted through mosquitoes to humans. Those at risk are individuals living in areas conducive to the breeding of mosquitoes, especially those that allow the mosquitoes to complete their growth cycle. Everyone is at risk
Malaria (also called biduoterian fever, blackwater fever, falciparum malaria, plasmodium, Quartan malaria, and tertian malaria) is one of the most infectious and most common diseases in the world. This serious, sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. It claims more lives every year than any other transmissible disease except tuberculosis. Every year, five hundred million adults and children (around nine percent of the world’s population) contract the disease and of these, one hundred million people die. Children are more susceptible to the disease than adults, and in Africa, where ninety percent of the world’s cases occur and where eighty percent of the cases
Malaria is spread by the female Anopheles mosquito.When the mosquito bites the malaria parasite is passed into the human bloodstream, infecting them and this works both ways, if a human has previously been given the parasite and a unaffected mosquito bites them, the mosquito will pick up the parasite and spread it further. For the mosquito to survive it the humidity must be high, and the temperature must be between 15°C and below 40°C. Stagnant pools of water allow the mosquito to live. It uses areas like marshes, lakes and river pools to breed. Increasing population growth can encourage people to live closer to affected areas that were previously avoided, such as close to river pools. Normally the
Malaria has been a huge problem among many developing nations over the past century. The amount of people in the entire world that die from malaria each year is between 700,000 and 2.7 million. 75% of these deaths are African children (Med. Letter on CDC & FDA, 2001). 90% of the malaria cases in the world are located in Sub-Saharan Africa. Once again, the majority of these deaths are of children (Randerson, 2002). The numbers speak for themselves. Malaria is a huge problem and needs to be dealt with immediately.
A general factors that effects the transmission of disease is the weather of countries. For example, in Africa the weather is really hot which means mosquitos are able to survive through bites? Malaria would be spread through the bites of the mosquitos. Therefore, many people that are suffering from malaria in Africa spend most of their income of treatments. Even though malaria has been eliminated from temperature climates, it will still affect the sub-tropical and tropical regions. Malaria is one of the major public health challenges due to poor counties. However, people that have high incomes will be able to prevent themselves rather than suffering from the disease. Not being able to pay for vaccine is the biggest factor as it affects
Malaria is found around the equator, mostly on the continent of Africa. 3.6 billion people live in Malaria exposed areas. That means about 50% of the population is exposed, while 300-400 million people get it every year. Malaria is a parasite, meaning it really isn’t a disease. Mosquitoes spread the Malaria parasite by biting an infected person. When they do that they take the blood containing the parasite, and the parasite then lives in it saliva. Then the next time the bite someone, the parasite then travels into its’ next host. Malaria can only thrive in areas that are warm because it has to live all year to be able to spread.
The pathway of malaria transmission from the mosquito to a person is detailed as after the mosquito has the parasite, the mosquito then bites the human, the parasite is released into the human, the parasite then goes to the liver and replicates itself, after replication the parasite enter the blood stream and attach to a red blood cell; the parasite is undetected by the immune system because it is attached to the red blood cells, the red blood cells is deformed from the parasite infection. The deformed red blood cell shape makes it stick to the cell membrane until it explodes and little particles from the red blood cell rushes through out the body; the cells goes through the body and enter other vitals
Malaria is an ancient disease. The name itself traces its origins to Medieval Italian: “mal aria” or bad air referred to a swampy area of Rome known as the Pontina that saw very high infection rates (Beltz, 2011). To this day, the disease continues to be one of the most important parasitic infections known to man. According to the World Health Organization, 3.4 million people may be considered at risk on a global scale and estimates indicate that there were 207 million cases in 2012 with 627,000 deaths (WHO, 2013). More than 85% of these cases occur on the continent of Africa as well as 90% of the deaths. In highly endemic regions, malaria is more of an issue of morbidity than mortality, although the majority of individuals may be parasitized at any given time only a minority exhibit severe symptoms (Marsh & Snow, 1997). Instead these countries are at a significant economic disadvantage due to ill workers, lack of tourism and company investments, not to mention the educational loss future generations also incur.
To begin with, the difficulty in eradicating Malaria by trying to change the environmental factors is, quite simply, there is only so much we can control. There is no doubt that there is a link between the frequencies of Malaria and climate it is found in. It is extremely prevalent in Africa, specifically the countries closest to the Equator. The tropical and sub-tropical regions of countries like Chad and Sierra Leone are ideal conditions for the mosquitoes that necessary for the transmission of the parasite to humans.
According to Malariasymptons.org, once a person is infected with malaria or the parasite plasmodium falciparum, they will experience fever-like sickness. The symptoms include “ fever, sweats, shaking chills, headaches, muscle aches, nausea, vomiting and diarrhea (malariasymptoms.org).” If malaria is not treated right away, it can lead to serious health issues for the person who is infected. It may eventually lead to kidney failure, seizures, mental confusion, coma, bleeding due to blood clots and even death (malaria symptoms.org).
Malaria is one of the most popular infectious diseases and a major public health problem worldwide. Billions of people are at risk of infection in 109 countries. Annually, there are an estimated 250 million cases of malaria leading to about one million deaths. Malaria is a disease that is caused by parasites in the red blood cells of a human body, and is usually transmitted by the bite of certain species of mosquitos.
Other research projects have estimated the number of cases between 350 and 550 million and 1.24 million deaths in 2012. The highest cases of malaria have been found in tropical and sub-tropical areas (Isiguzo et al., 2014). These areas include Africa, India, Southeast Asia, Hati, and the Middle East (Kiszewski et al., 2014). These areas all have low/poor living conditions and lower or no health standards compared to the Unites States. Studies have shown areas with poor living conditions have increased amounts of mosquitoes due to their inability to destroy breading habitats or spray their land with mosquito pesticides. This increases the chances of someone coming into contact with an infected Anopheles mosquito carrying the Plasmodium protozoan parasite. Studies have found that Plasmodium originated from Africa and is now found on every continent besides Antarctica, which is too cold to support mosquito populations. This parasite was able to spread from Africa due to advances in locomotion such as ships and aircraft.
Malaria is responsible for millions of deaths every year. More than two million people die from malaria each year with about 90% of these deaths occurring in sub-Saharan Africa (MVI, 2015). Most of these deaths are in children under the age of five. The species responsible for malaria is Plasmodium. They are classified under Apicomplexaphyla and are unicellular and chemoheterotrophic. It is spread via vectors and requires a host for reproduction (Alex, 2015). There are five species of Plasmodium responsible for malaria. The most deadly species is Plasmodium falciparum. P. falciparum multiplies rapidly in the blood and can cause severe blood
Malaria is one of the ten most common, yet deadly diseases in the world. It is a parasitic disease spread by the bite of Anopheles mosquito, which is active between dusk and dawn. Malaria occurs in over 100 countries and territories.
India, being a malaria endemic zone, confronts this protozoan disease perennially[4]. India’s wide-spread geography, ecological diversity and climatic variability make it an ideal place for malaria parasites and their vectors to sustain[5].Currently, about 95% of the 1.21 billion population of India is at risk of malarial infection [6, 7]. An estimated 1.5 million cases and 1000 deaths are attributed to malaria annually in this region[6, 8]. In year 2012, India contributed about 52% of the total cases out of the 2 million confirmed malaria cases in South- East Asia [3]. However, in the last decade, India has made good progress in controlling the
