Malaria
parasitic infection spread by Anopheles mosquitoes (female mosquito)
Cause Protozoan parasites of the genus Plasmodium, that causes malaria is neither a virus nor a bacterium – it is a single-celled parasite that multiplies in red blood cells of humans as well as in the mosquito intestine. It blocks the passage for the blood to get to the brain
• There are 5 parasite species that cause malaria in humans, and 2 of them (P. falciparum and P. vivax) pose a deadly threat.
Transmission - Bitten by an infected mosquito
• Places where the mosquitos lifespan is longer, usually has harsh implications because the disease has had time to complete its development inside the mosquito - Receiving infected

Major syptoms Nausea and vomiting, fever, headache, sweats, fatigue, chills
If not treated within 24 hours, P. falciparum malaria can progress to severe illness, often leading to death.
Treatment Early diagnosis and treatment of malaria reduces disease and prevents deaths. It also contributes to reducing malaria transmission.
• Anti-malarial drugs such as quinine and chloroquinine
Prevention Cover up after dark and use personal insecticide, mosquito nets , window screens, anti-malarial drugs to prevent the disease, which need to be taken prior to travel to affect countries
Control Draining swamps, spraying with insecticides.

Resistance to antimalarial medicines is because chemicals used in the drug like chloroquine and sulfadoxine-pyrimethamine (SP) were used commonly in the 1970s and 1980. Parasites have built a resistance to the drug over the years. The use of netting treatment with long-lasting insecticide and the normal measures to prevent being bitten by the mosquitto are still the most effective ways to prevent infection by a malaria
In the article “When Mosquitoes Were Killers in America” by Lauren Tarshis, She makes the statement “Yet mosquitoes are far more than a nuisance.” What she means is that mosquitoes aren't a little bug that just sucks a little blood and can be annoying, but instead it uses all that and more. Mosquitoes have killed millions upon millions of people by spreading disease like malaria. An example of how she supports this claim is in the article, she says “ In this way, bite by itchy bite, 212 million people are infected with malaria every year” (Tarshis 13). And that is only a year with bug spray, shots, and all the other things that help stop mosquitoes. So when the U.S. government tried to save people from these murders little insects. So they
... States are minimal for people affected with disease by this invasive species, steps should still be taken to avoid an outbreak. They should be controlled to some extent. Because West Nile has taken such a toll on humans and birds, precautions should be taken to avoid being infected with this disease. Controlling the Asian Tiger Mosquito may help minimize the spread of diseases throughout the United States. Because this species of mosquito thrives in more wet condensed spaces like water cans, tipping and tossing all containers that hold water around the house or garden on a daily basis will help remove the larvae and reduce the population. Other common practices that most communities partake in, include cold fogging or spray trucks and effective mosquito traps. These are the best options so far, to help control the Asian Tiger mosquito and other mosquitos as well.
Because of the occurrence of the Black Death, advancements in medicine were made that helped us to be where we are today in the medical field. The Black Death first began...
... develop resistance. This means that this disease will most likely be around for a long period of time, as the drugs developed will eventually become useless. Resistance to malaria drugs is a natural consequence of widespread use of the drug. This means that the drugs should not be used often, but if it spreads, they will have to be used more. To protect against this, the global authorities are trying to assure that the best drug used to fight it is only sold as a combination pill with other anti-malaria medicines.
This disgusting worm parasite is spread by flies and mosquitoes. The adult worm spreads its larvae throughout the host’s lymphatic system and causes the lymph nodes to become clogged up. This also makes the tissue in the host’s body to swell up and create massive muscle deformations, otherwise known as elephantiasis. The elephantiasis mainly affects the legs and genitals. The disease also affects the eyes but that can be easily detected through close inspection but it commonly causes river blindness in the host. It’s been estimated that the parasite is one of the leading causes of blindness throughout the world.
It is caused by parasites of the Plasmodium species(in text reference). These parasites are carried by mosquitoes which become infected after biting someone who has malaria. Malaria is then passed on to others when the infected mosquito bites another person. In rare cases malaria can be passed to another person through blood transfusions, organ donations or shared needles.
A person can prevent the disease. And, there are many ways to do this. One is to put on insect repellent with Deet. Another is to wear long sleeves and long pants. Also, tuck your pants in socks. And, wear a hat. Finally, stay away from wooded areas.
Malaria kills more people than any communicable disease except for tuberculosis. It is caused by four species of parasitic protozoa that infect human red blood cells. Four different types of these protozoa are known: protozoa falciparum, protozoa vivax, protozoa ovale, and protozoa malariae. Protozoa falciparum is the most lethal of the four and accounts for the majority of infections. Malaria parasites are not able to survive unless they have both a mosquito and human host, however the disease cannot be hosted by any kind of mosquito, only those of the genus "anopheles".
The seventh major case of Endangered Specie. Specific species of mosquito play host to one phase of various disease organisms they are the cause of major diseases that lead to human compilation. Most people don’t find it wrong to wipe the entire mosquito species in other to prevent human diseases such as sleeping sick, malaria, and human
Malaria is a disease that is caused by parasites. It is transferred from one person to another by the infected female Anopheles mosquito. Malaria has been a serious health problem nowadays. WHO has provided the information that approximately 660,000 people died from malaria globally during 2010. Also, after estimating, there are 219 million cases of malaria infection in 2010 worldwide. In sub-Saharan Africa, being one the country that has the high rate of HIV, AIDS, malaria, and tuberculosis, had 90% of the people that...

Since yellow fever is carried by mosquitoes, it is most often found in areas such as Central America, the northern half of South America, and Central Africa where mosquitoes are abundant. The reason why it is found so often in these regions is because they are very close to the equatorial line, and are there for hot, moist, tropical environs. Yellow fever is also found in other areas besides the ones listed above. It can also be carried throughout South America and all of Africa. Even though it can be carried to these places, it is more often than not confined to areas surrounding the equator because mosquitoes have short life spans and yellow fever can be contracted and spread all year long in these tropical regions.
Malaria in humans is caused by four species of protozoa, sophisticated one-celled organisms, that can infect red blood cells. These four species are called Plasmodium falciparum, plasmodium vivax, plasmodium malariae, and plasmodium ovale. The worst cases are caused by the Plasmodium falciparum species, which is also the species with the most resistance to drugs. To contract malaria, a mosquito, but not just any mosquito must bite a human. The only type of mosquito that can infect humans with the malaria virus is the Anopheles mosquito. While there are...
Microscopy will be performed on the patient to establish the type of malaria parasite and the number of these parasites in his/her blood sample. The blood sample can be extracted through a finger stab and then made into thick and thin films, and examined severally using a 100x oil immersion objective after staining them with Romanovsky stain (Warrell, Cox, & Firth, 2005, p. 734). By observation, the species of plasmodium can be seen and the number of them established
Use mosquito nets impregnated with insecticides in places where screens for doors and windows are absent.
