Malaria: 1. Introduction
Malaria is a life-threatening mosquito-borne blood disease. The Anopheles mosquito transmits it to humans. The parasites in mosquitos that spread malaria belong to the Plasmodium genus. Over types of Plasmodium parasite can infect a variety of species. Different types replicate at different rates, changing how quickly the symptoms escalate, and the severity of the disease, malaria essay.
Five types of Plasmodium parasite can infect humans, malaria essay. These malaria essay in different parts of the world.
Some cause a more severe type of malaria than others. In some places, early diagnosis can help treat and control malaria. However, some countries lack the malaria essay to carry out effective screening. Currently, no vaccine is available for use in the United Malaria essay, although one vaccine has a license in Europe. In the early s, advances in treatment eliminated malaria from the U.
However, between 1, and 2, cases still occur each year, mostly in those who have recently traveled to malaria-endemic areas. Doctors divide malaria symptoms into two categories : Uncomplicated and severe malaria.

As symptoms resemble those of flumalaria essay may remain undiagnosed or misdiagnosed in areas where malaria is less common, malaria essay.
In areas where malaria is common, many people recognize the symptoms as malaria and treat themselves without visiting a doctor. Those without symptoms may be treated for infection to reduce the risk of disease transmission in the surrounding population. The World Health Organization WHO recommends artemisinin-based combination therapy ACT to treat uncomplicated malaria.
Artemisinin is derived from the plant Artemisia annuabetter known as sweet wormwood. It rapidly reduces the concentration of Plasmodium parasites in the bloodstream.
Practitioners often combine ACT with a partner drug. ACT aims to reduce the number of parasites within the first 3 days of infection, while the partner drugs eliminate the rest. Expanding access to ACT treatment worldwide has helped reduce the impact of malaria, malaria essay, but the disease is becoming increasingly resistant to the effects of ACT.
The WHO has warned that no alternatives to artemisinin are likely to become available for malaria essay years. Research to develop safe and effective global vaccines for malaria is ongoing, with the licensing of one vaccine already having occurred in Europe. No vaccine is yet licensed in the U. While malaria is not endemic to the U. The Centers for Disease Control advise travelers to take the following precautions :.

For a year after malaria essay home, the traveler may be susceptible to symptoms of malaria. Donating blood may also not be possible for some time. Malaria happens when a bite from the female Anopheles mosquito infects the body with Plasmodium. Only the Anopheles mosquito can transmit malaria.
The successful development of the parasite within the mosquito depends on several factors, malaria essay, the most important being humidity and ambient temperatures.
When an infected mosquito bites a human host, the parasite enters the bloodstream and lays dormant within the liver. The host will have no symptoms for an average of The liver then releases these new malaria parasites back into the bloodstream, where they infect malaria essay blood cells and multiply further.
Some malaria parasites remain in the liver and do not circulate til later, resulting in recurrence, malaria essay. An unaffected mosquito acquires parasites once it feeds on a human with malaria. This restarts the cycle, malaria essay. The WHO strongly advise confirmation of the parasite through microscopic laboratory testing or by a rapid diagnostic test RDTdepending on the facilities available.
