Malaria caused by plasmodium vivax

Malaria Caused by Plasmodium Vivax.

Malaria is a major killer in much of the world. It's a disease caused by any one of five species of the Plasmodium parasite - Plasmodium falciparum, vivax, ovale, malariae, and knowlesi. Unlike the other four, vivax malaria has the potential to cause repeated episodes of illness and thus presents a significant public health problem. Here’s what you need to know about this dangerous strain.

What is Plasmodium Vivax?

Plasmodium vivax is the most common and widespread form of the malaria parasite. It is found in most tropical and subtropical areas around the world, especially in the Indian subcontinent and Central and South America. It can cause both acute and recurring (“relapsing”) malaria.

How Does it Cause Malaria?

Malaria is transmitted to humans by the bite of an infected female Anopheles mosquito. The parasite, which multiplies in the female mosquito's gut, is then injected into the recipient's bloodstream when the mosquito feeds. In the human body, the parasites migrate to the liver where they multiply. After an incubation period of 10-32 days, depending on the species, they emerge from the liver in large numbers of parasites, and enter the bloodstream, causing severe symptoms.

Symptoms of Malaria Caused By Plasmodium Vivax

Symptoms of malaria caused by Plasmodium vivax typically include fever, shaking, headaches, sweating, and vomiting. These can last several days and may be accompanied by an enlarged spleen, anemia, and jaundice. In some cases, symptoms may not manifest until weeks or even months after the initial infection.

Treatment of Plasmodium Vivax Malaria

Treatment of malaria caused by Plasmodium vivax is with antimalarial medications, such as chloroquine, quinine, mefloquine, and atovaquone/proguanil. It is important to note that medications used for other types of malaria are not effective against Plasmodium vivax. As such, it is important to get a definitive diagnosis and the appropriate treatment.

Prevention of Plasmodium Vivax Malaria

The key to prevention of malaria caused by Plasmodium vivax is to avoid mosquito bites as much as possible. This includes using insect repellent, wearing long sleeves and pants, and using bed nets while sleeping in areas where malaria may be more prevalent. In addition, travelers to countries with high malaria rates should consult a doctor and get the appropriate prophylactic medications.

Complications of Plasmodium Vivax Malaria

  • Anemia
  • Enlarged spleen
  • Jaundice
  • Organ failure
  • Seizures
  • Respiratory distress

It's important to seek treatment for malaria as soon as possible in order to reduce the risk of severe complications from the vivax strain.
