What You Need to Know about Malaria in Thailand

Dealing with rainy seasons (June to October) in Thailand could be tricky due to malaria. In this Pacific Prime Thailand article, we will provide a brief overview of malaria. You can expect to learn its epidemiology, causes, symptoms, diagnosis, treatment, and prevention methods.

Malaria is prevalent in tropical and subtropical regions around the world. In Thailand, urban areas are generally risk-free, such as Bangkok, Chiang Mai, Pattaya, etc; whereas endemic areas are typically the hilly or forested rural areas, especially Thai-Myanmar and Thai-Cambodia border.

The ‘Land of Smiles’ does have some hard-to-resist vibe and culture that are sure to blow your mind. But, make sure you are aware of the disease before immersing yourself in joy and laughter.

Malaria

Malaria has been affecting the globe for centuries. Unfortunately, Thailand is classified as one of the malaria countries. In this quick introduction, you can learn the basics about the disease, from causes and symptoms to diagnosis and treatment. And of utmost importance, prevention is key.

Epidemiology

Malaria is a mosquito-borne infectious disease caused by Plasmodium parasites. Until today, 4 types of Plasmodium species are known to harm humans: P. falciparum, P. vivax, P. ovale, and P. malariae. Among them, P. falciparum is the deadliest, which can cause severe anemia and end-organ damage.

The existence of Malaria 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 in Thailand.

Risk Groups

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.

Malaria is a burden in some nations without a fully-developed medical system. It disproportionately affects children under 5 and those residing in rural areas where access to medical treatments is limited. Therefore, sub-urban/ rural areas in Thailand are susceptible to malaria.

Transmission

Malaria is transmitted by infected Anopheles 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.

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.

Symptoms

Depending on the malaria strain infected, the latent period varies from 9 days to over 1 year. Typical medical manifestations include:

• Fever
• Fatigue
• Vomiting
• Headaches
• Sweats
• Chills

In more severe cases, it can cause:

• Jaundice
• Seizures
• Coma
• Death

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. Depending on the malaria strain, the periodicity varies between 36 hours to 3 days.

Without proper treatment, the debilitating cycle can continue for years. Therefore, approaching trusted medical professionals is key to curing malaria in Thailand. Reaching out to ever-saturated public medical services as an expat is not easy, so read on! We have a solution for you.

Diagnosis

The gold standard of diagnosis for malaria is a microscopic examination of blood. It provides 3 valuable pieces of information: the presence of malaria, malaria species, and the percentage of red blood cells infected. These are key information in planning an appropriate treatment.

There are also various test kits available to detect antigens derived from malaria parasites. These Rapid Diagnostic Tests offer a reliable source of testing where microscopy is not possible. If tested positive, reach out for medical treatment as soon as possible.

Treatment

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.

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 are dependent on factors such as the type of malaria, patients’ health status, age, etc.

Safety & Prevention

There are two directions for prevention. One is the prevention of mosquito bites and the other is the prevention of mosquito proliferation.

Prevention of Mosquito Bites

Mosquitoes are proactive from dusk to dawn. One should be actively practicing preventive measures indoors and outdoors to drive them away from you.

• Wear loose, light-colored, long-sleeved tops and trousers
• Use insect repellent containing DEET (30%) on exposed body parts
• Avoid using fragrances outdoors
• Re-apply insect repellents whenever necessary (once every 2-3 hours)
• Use bed nets or screens with insecticide sprayed on while sleeping

Prevention of Mosquito Proliferation

To create a mosquito-free area, you should pay attention to environmental hygiene. Make sure your surroundings are not desirable for their breeding.

• Prevent accumulation of stagnant water
• Store food and dispose of garbage properly

Having that said, expats should also arrange a consultation with a doctor before going to and in Thailand for preventive measures and obtain anti-malarial drugs if necessary.
