Malaria is a female Anopheles mosquito-borne infectious disease. It is caused by a one-celled parasite called a Plasmodium that affects humans & other animals.
when once parasites are into the body, they travel to the liver, where they mature. After several days, the mature parasites enter the bloodstream & begin to infect red blood cells(RBC).
Symptoms Of Malaria
Malaria signs & symptoms begin within a few weeks after being bitten by an infected mosquito. Yet, some kinds of malaria parasites can lie dormant in the body for about a year.
Here will be some things to remember in mind, though:
- Because the signs are so similar to cool or flu symptoms, this might be hard in order to tell what you possess at first.
- Malaria symptoms don’t always show up within two weeks, especially if it’s a P. vivax infection.
A blood test can easily confirm whether you need malaria
Malaria symptoms are:
- Typically fever,
- Nausea & vomiting,
- Muscle pain & fatigue
- Body aches
- shaking chills that can range from moderate to severe
- high fever
- Loss of appetite
Other signs & symptoms may include:
- Chest or abdominal pain
- shivering & chills
- variation in body temperature e.g. one day high while next day normal… so on… plus minus
In severe cases, it can cause
- Yellow skin,
- Bloody stools
- Kidney failure
- Coma or death
Every year, approximately 219 million people are infected with malaria, & about 435,000 people die from malaria. Most of the people who die from malaria are young children in Africa,(the report in 2017 of WHO).
Scientists around the world are working to produce a vaccine to prevent malaria.
Types Of Malaria Parasite
There are some different types of plasmodium parasite, but only five types cause malaria & illness in humans.
- Plasmodium falciparum ( P. falciparum)
- Plasmodium malariae ( P. malariae)
- Plasmodium vivax ( P. vivax)
- Plasmodium ovale ( P. ovale)
- Plasmodium knowlesi ( P. knowlesi)
Most dangerous types of malaria:
Plasmodium falciparum ( P. falciparum)
P. falciparum is the most common malaria parasite in Africa, & it causes the most malaria-related deaths in the world. P. falciparum multiplies very quickly, causing severe blood loss & clogged blood vessels.
P. falciparum is therefore regarded as the deadliest parasite in humans, causing 435,000 deaths in 2017. It will be also linked with the development of blood cancers (Burkitt’s lymphoma)
As of the latest World Malaria Report of the World Health Organization(WHO), there were 219 million cases of malaria worldwide in 2017, up from 216 million cases in 2016. This resulted in an estimated 435,000 deaths. Almost every malarial death is caused by P. falciparum.
Plasmodium vivax ( P. vivax)
P. vivax. is the malaria parasite most commonly found outside of sub-Saharan Africa, especially in Asia & Latin America.
Plasmodium vivax is a protozoal parasite & a human pathogen. This parasite is the most frequent & widely distributed cause of recurring malaria.
Although this is less virulent than Plasmodium falciparum, the deadliest of the five human being malaria parasites, P. vivax malaria infections can guide to severe disease & death, often due to splenomegaly (a pathologically increased spleen).
