Understanding Dengue Fever

What is Dengue Fever?

Dengue fever is caused by the dengue virus, which is transmitted through the bite of infected mosquitoes. Symptoms can range from mild to severe and typically appear 4 to 10 days after being bitten. Common symptoms include high fever, severe headaches, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. In some cases, dengue can progress to severe dengue, which can be life-threatening.

How is Dengue Transmitted?

The primary vector for dengue transmission is the Aedes mosquito, which is most active during the day. These mosquitoes breed in stagnant water, making urban areas in Thailand particularly susceptible to outbreaks. Understanding the transmission cycle is crucial for minimising your risk while travelling.

Dengue Fever in Thailand

Current Situation

Thailand is known for its tropical climate, which provides ideal conditions for the Aedes mosquito. The country experiences seasonal outbreaks of dengue, particularly during the rainy season from May to October. According to the Thai Ministry of Public Health, the number of reported dengue cases can vary significantly from year to year, with some regions experiencing higher incidences than others.

Regions at Risk

While dengue can occur throughout Thailand, certain areas are more prone to outbreaks. Urban centres like Bangkok, Chiang Mai, and Phuket have reported higher cases due to their dense populations and stagnant water sources. Travellers should be particularly cautious when visiting these areas.

Statistics and Trends

Recent statistics indicate that Thailand has seen fluctuations in dengue cases, with thousands of reported infections each year. The World Health Organization (WHO) monitors these trends, and it is advisable for travellers to stay updated on the current situation before their trip.

Assessing Your Risk

Factors Influencing Risk

Several factors can influence your likelihood of contracting dengue while in Thailand. These include the time of year, the specific regions you plan to visit, and your personal health and immunity. Understanding these factors can help you make informed decisions about your travel plans.

Personal Health Considerations

Individuals with weakened immune systems or pre-existing health conditions may be at a higher risk for severe dengue. If you have concerns about your health, consult with a healthcare professional at the Edinburgh Travel Clinic before your trip to discuss your specific risks and necessary precautions.

Travel Duration and Activities

The length of your stay and the activities you engage in can also affect your risk. Spending more time outdoors, particularly in areas with dense vegetation or near water sources, increases your chances of mosquito bites.

Preventative Measures

Vaccination

Currently, there is a dengue vaccine available, known as Dengvaxia, which is recommended for individuals aged 9 to 45 who have previously been infected with dengue. However, vaccination is not universally recommended for all travellers, especially those who have never had dengue before. It is crucial to consult with a healthcare professional at the Edinburgh Travel Clinic to determine if vaccination is appropriate for you. Book your dengue vaccine now to ensure you are protected before your trip.

Mosquito Bite Prevention

Preventing mosquito bites is the most effective way to reduce your risk of dengue. Here are some essential tips:

• Use insect repellent: Apply a repellent containing DEET, picaridin, or oil of lemon eucalyptus to exposed skin.

• Wear protective clothing: Opt for long sleeves and long trousers, especially during peak mosquito activity times.

• Stay in screened or air-conditioned accommodations: This can significantly reduce your exposure to mosquitoes.

• Avoid areas with stagnant water: Mosquitoes breed in standing water, so be cautious in such environments.

What to Do if You Get Sick

Recognising Symptoms

If you develop symptoms of dengue while in Thailand, it is essential to seek medical attention promptly. Early diagnosis and management can help prevent severe complications. Symptoms to watch for include high fever, severe headaches, and joint pain.

Seeking Medical Care

In Thailand, there are numerous healthcare facilities available for tourists. It is advisable to visit a reputable hospital or clinic if you suspect you have dengue. Ensure you have travel insurance that covers medical expenses abroad.
