In December 2017, the World Health Organization (WHO) released its latest report estimating 216 million cases of malaria. Also WHO estimated approximately 446,000 deaths caused by malaria while 91 countries have been identified with ongoing malaria transmission. Of the countries, 15 countries–all in Sub-Saharan Africa–carry 80% of the global malaria burden. Kyrgyzstan and Sri Lanka were certified by WHO as malaria free in 2016 and more countries are moving towards elimination.
In 2018, malaria continues to plague most countries in Africa with more outbreaks in Namibia and South Africa in recent months. AIG Travel has assisted many customers with malaria symptoms over the past years, primarily in Asia and Africa. From our experience, the mortality rate for malaria is reduced when the disease is detected early; hence, it is important to be fully aware of the potential exposure to malaria when traveling to these endemic areas.
What is Malaria?
Malaria is a potentially fatal tropical disease caused by a parasite known as Plasmodium. It spreads through the bite of an infected female Anopheles mosquito. These mosquitoes are most active between 9 p.m. and 5 a.m. There are four parasite species that cause malaria in humans:
Plasmodium falciparum and Plasmodium vivax are the most common, while Plasmodium falciparum is the most deadly. In recent years, some human cases of malaria have also occurred with Plasmodium knowlesi–a speciesthat causes malaria among monkeys and occurs in certain forested areas of Southeast Asia.
The parasites develop in the intestine and salivary glands of the mosquito and can be passed onto humans the next time the mosquito bites. In humans, the parasite travels to the liver via the blood and then out into the bloodstream again, where it invades the red blood corpuscles (the cells that carry oxygen in the blood). Malaria can also be spread through blood transfusions, and the use of infected needles.
Typically 7 to 30 days pass between being infected and the onset of the disease. Symptoms include:
Once their temperature drops, the patient often sweats profusely and feels much better. Further symptoms may occur within a day or two. The symptoms diminish over the course of several weeks if the patient develops the ability to resist the malaria parasite. If proper treatment is given, the fever and parasites may disappear within a few days. If a case develops into severe malaria, the classic symptoms may be coupled with increased drowsiness and other complications including:
Prevention of Malaria
Prevention requires A, B, C and D:
Antiviral drugs are prescription medicines (pills, liquids or inhaled powders) and are not available for purchase over‐ the‐counter. These drugs should be used within the first two days of symptoms to treat people who are very sick (such as those who are hospitalized) or people with flu symptoms with an increased risk of severe flu illness (i.e., pregnant women, young children, people 65 and older and people with certain chronic health conditions).
Early diagnosis and treatment of malaria reduces the disease and prevents deaths. It also contributes to reducing malaria transmission. WHO also recommends that all cases of suspected malaria be confirmed using parasite-based diagnostic testing (either microscopy or rapid diagnostic test) before administering treatment. Results of parasitological confirmation can be available in 15 minutes or less. Treatment solely on the basis of symptoms should only be considered when a parasitological diagnosis is not possible.
Preventive Medicines Include:
Atovaquone/ proguanil (Malarone)
