Malaria,symptom and causes

Malaria,symptom and causes;What is malaria?Malaria is a life-threatening disease. It’s typically transmitted through the bite of an infected Anopheles mosquito. Infected mosquitoes carry the Plasmodium parasite. When this mosquito bites you, the parasite is released into your bloodstream.

Once the parasites are inside your body, they travel to the liver, where they mature. After several days, the mature parasites enter the bloodstream and begin to infectred blood cells.

Within 48 to 72 hours, the parasites inside the red blood cells multiply, causing the infected cells to burst open.

The parasites continue to infect red blood cells, resulting in symptoms that occur in cycles that last two to three days at a time.

Malaria is typically found in tropical and subtropical climates where the parasites can live. The World Health Organization (WHO) states that, in 2016, there were an estimated 216 million cases of malaria in 91 countries.

Causes of malaria?

Malaria can occur if a mosquito infected with the Plasmodium parasite bites you. There are four kinds of malaria parasites that can infect humans: Plasmodium vivax,P. ovale, P. malariae, and P. falciparum.

P. falciparum causes a more severe form of the disease and those who contract this form of malaria have a higher risk of death. An infected mother can also pass the disease to her baby at birth. This is known as congenital malaria.

Malaria is transmitted by blood, so it can also be transmitted through:

  1. an organ transplant
  2. a transfusion
  3. use of shared needles or syringes

Symptoms of malaria?

The symptoms of malaria typically develop within 10 days to 4 weeks following the infection. In some cases, symptoms may not develop for several months. Some malarial parasites can enter the body but will be dormant for long periods of time.

Common symptoms of malaria include:

  • shaking chills that can range from moderate to severe
  • high fever
  • profuse sweating
  • headache
  • nausea
  • vomiting
  • abdominal pain
  • diarrhea
  • anemia
  • muscle pain
  • convulsions
  • coma
  • bloody stools

Tips to prevent malaria

There’s no vaccine available to prevent malaria. Talk to your doctor if you’re traveling to an area where malaria is common or if you live in such an area. You may be prescribed medications to prevent the disease.

These medications are the same as those used to treat the disease and should be taken before, during, and after your trip.

Talk to your doctor about long-term prevention if you live in an area where malaria is common. Sleeping under amosquito net may help prevent being bitten by an infected mosquito. Covering your skin or using bug sprays containing DEET] may also help prevent infection.

If you’re unsure if malaria is prevalent in your area, the CDC has an up-to-date map of where malaria can be found.
