Further reading:<\/strong> Top 13 Diseases and Medical Conditions in Thailand that Expats Should Be Aware Of<\/a><\/p>\n Malaria is a mosquito-borne infectious disease caused by Plasmodium<\/em><\/a> parasites. Until today, 5 types of Plasmodium species are known to harm humans: P. falciparum, P. vivax, P. ovale, P. malariae, and P. Knowlesi<\/em>.<\/p>\n Among them, P. falciparum is the deadliest (75% of total deaths), which can cause severe anemia and end-organ damage within 24 hours, usually found in Africa; P. vivax accounts for 20% of total deaths by malaria and is the dominant parasite in most countries outside sub-Saharan Africa.<\/p>\n The existence of Malaria<\/a> mainly depends on climatic factors such as temperature, humidity, and rainfall. Since mosquitoes lay eggs on the surface of water containing heavy vegetation, it is one of the diseases most commonly spread during wet seasons<\/a> (June to October) in Thailand.<\/p>\n Malaria has been affecting the globe for centuries. Unfortunately, Thailand is classified as one of the malaria countries.<\/p>\n Malaria remains a significant health challenge in Thailand even though the government has made substantial progress in malaria control and elimination. The disease still poses a threat, particularly in regions with dense forests such as the borders with Myanmar and Cambodia.<\/p>\n The disease thrives in humid environments with temperatures between 20-30\u00b0C, which are optimal for both parasite development and mosquito survival. Most malaria cases in Thailand are reported at altitudes below 1,500 meters and in proximity to water bodies, where mosquitoes breed.<\/p>\n Although the overall incidence of malaria has decreased significantly over the past two decades, certain populations remain at higher risk. Vulnerable groups include children under 5 years old, pregnant women, and migrant workers who may have limited access to healthcare.<\/p>\n There is a clear rural-urban divide in malaria transmission in Thailand. Rural areas have seen higher rates of transmission, likely due to poverty contributing to limited access to healthcare and preventive measures. Poor housing conditions and a lack of resources further exacerbate the situation.<\/p>\n Anyone can get malaria. Most cases occur in people who live in countries with malaria transmission. People from countries with no malaria can become infected when they travel to countries with malaria. Hence, regular check-ups are required when residing in places with reported malaria cases.<\/p>\n Malaria is a burden in some nations without a fully developed medical system and suburban\/rural Thailand is no exception. It disproportionately affects children under 5 and those residing in rural areas where access to medical treatments is limited, including:<\/p>\n Malaria is transmitted by infected Anopheles<\/em><\/a> mosquitoes. When mosquitoes bite any malaria patient, they become infected and will pass on the disease when biting another person. Malaria is not contagious, meaning causal contact with malaria-infected people is safe.<\/p>\n However, Plasmodium parasites are found in the red blood cells of an infected person. This signifies that malaria can also be transmitted through blood transfusion, organ transplant, or the shared use of needles or syringes contaminated with blood.<\/p>\n Depending on the malaria strain infected, the latent period varies from 9 days to over 1 year. Typical medical manifestations<\/a> include:<\/p>\n In more severe<\/a> cases, it can cause:<\/p>\n A classic symptom of malaria is paroxysm, a cyclical occurrence of sudden coldness followed by shivering and then fever and sweating. Hence, the disease can also be observed through patterned fluctuations in body temperature. The periodicity varies between 36 hours to 3 days depending on the malaria strain.<\/p>\n Without proper treatment, the debilitating cycle can continue for years. Therefore, approaching trusted medical professionals is key to curing malaria in Thailand.<\/p>\n Symptoms: Healthcare providers begin by evaluating symptoms, which typically include fever, chills, headache, fatigue, nausea, and muscle aches. A history of travel to malaria-endemic areas is crucial for diagnosis.<\/p>\n Physical Examination: Doctors may look for signs such as anemia, jaundice, or splenomegaly (enlarged spleen).<\/p>\n Laboratory tests provide 3 valuable pieces of information: the presence of malaria, malaria species, and the percentage of red blood cells infected. All of these are key information in planning an appropriate treatment.<\/p>\n Blood Smear:<\/strong> The most common diagnostic method is a blood smear. A drop of blood is placed on a slide and stained to identify malaria parasites under a microscope. This method can confirm the presence of the parasite and the specific species.<\/p>\n Rapid Diagnostic Tests (RDTs): <\/strong>These tests detect specific antigens produced by the malaria parasite. RDTs are quick and can provide results within 15-20 minutes, making them useful in areas with limited access to laboratory facilities.<\/p>\n Polymerase Chain Reaction (PCR): <\/strong>PCR testing can identify malaria DNA in the blood. It is more sensitive and specific than blood smears but is typically used in research or complex cases due to higher costs and longer processing times.<\/p>\n If malaria is diagnosed, further tests may be conducted to determine the severity of the infection and guide treatment decisions. Monitoring for complications is essential, especially in severe cases.<\/p>\n Note: <\/strong>There are also various test kits available to detect antigens derived from malaria parasites. These Rapid Diagnostic Tests<\/a> offer a reliable source of testing where microscopy is not possible. If tested positive, reach out for medical treatment as soon as possible.<\/p>\n Early diagnosis and prompt treatment are crucial for malaria treatment. Doctors usually prescribe a course of anti-malarial drugs. It should be completed to ensure clearance of the malaria parasite and mitigate the possibility of relapses.<\/p>\n Doctors will choose your medication based on:<\/p>\n Anti-malarial drugs can cause side effects, depending on the medication, they can be:<\/p>\n The disease can continue if treated with the wrong drug. Species in some areas might already have developed drug resistance, thus the type of drugs and length of treatment can vary.<\/p>\n There are three general directions for prevention\u2014the prevention of mosquito bites, the prevention of mosquito proliferation, and getting prevention medication.<\/p>\n Prevention of mosquito bites minimizes your chances of contacting mosquitoes. You can do so by practicing the below protective measures.<\/p>\n Protective Clothing<\/strong><\/strong><\/p>\n Use Repellents<\/strong><\/strong><\/p>\n Home Protection<\/strong><\/strong><\/p>\n Outdoor Timing<\/strong><\/strong><\/p>\n Environmental hygiene is essential when it comes to creating a mosquito-free area. Make sure your surroundings are not desirable for mosquito breeding. There are some relatively easy measures to minimize your contact with mosquitoes, especially if you live in rural Thailand.<\/p>\n Travelers to malaria endemic areas should consult their doctor weeks before departure. Your medical professional will decide which preventive drug is the most appropriate for your country of destination.<\/p>\n Depending on the type of drug you get, chemoprophylaxis drugs could require you to start 2-3 weeks prior to departure. All prophylactic drugs should be taken on schedule for the duration of the stay and continued for up to 4 weeks after the last possible exposure to infection.<\/p>\n Common chemoprophylaxis drugs include:<\/p>\n Atovaquone\/proguanil (Malarone)<\/strong><\/strong><\/p>\n Doxycycline<\/strong><\/strong><\/p>\n Mefloquine (Lariam)<\/strong><\/strong><\/p>\n Early detection and intervention are key when it comes to treating malaria in Thailand. Many expats and travelers therefore opt for private healthcare to guarantee access to medical assistance whenever necessary.<\/p>\n Private healthcare has English-speaking staff and significantly lower waiting times compared with public healthcare. Opting for private healthcare is not cheap, but is made affordable with expat health insurance<\/a> or travel insurance<\/a>.<\/p>\n Insurers<\/a> offer various levels of health insurance plans, and we understand that it can be daunting to navigate all the plans and insurance jargon.
