Chikungunya’s unexpected comeback: What travellers need to know

Chikungunya is not new. It is a mosquito-borne viral disease that has caused outbreaks in many parts of the world over the years. For some time, it seemed under control, but now it is making an unexpected comeback in several countries. Travellers are at higher risk because they may visit regions where the infection is spreading. If you are planning a trip, here is everything you need to know to stay safe.

What is Chikungunya?

Chikungunya is a viral infection spread by the bite of infected Aedes mosquitoes, mainly Aedes aegypti and Aedes albopictus. These are the same mosquitoes responsible for spreading dengue and Zika virus. The name comes from an African language word that means "to become contorted" because the joint pain caused by the disease can be so severe that it bends the body.

The infection is rarely life-threatening, but it can cause serious discomfort and long-lasting weakness. For travellers, even a short trip to an affected area can lead to illness if preventive steps are not followed.

Why is Chikungunya Making a Comeback?

Health experts are noticing more chikungunya cases in areas where it had not been common before. This unexpected rise is linked to:

• Changing weather patterns that help mosquitoes breed for longer periods
• Increased travel and movement of people between countries
• Urbanisation, which creates crowded spaces and standing water where mosquitoes thrive
• Limited awareness among travellers about preventive measures

This combination has allowed chikungunya to re-emerge and affect both tropical regions and new areas across the globe.

Symptoms of Chikungunya

The symptoms usually appear between 3 to 7 days after being bitten by an infected mosquito. Travellers often mistake it for dengue or viral flu because of similar signs. Key symptoms include:

• Sudden high fever
• Severe joint pain, especially in the hands, wrists, ankles, or knees
• Muscle pain
• Headache
• Fatigue
• Rash on the skin

The joint pain is the most notable symptom and can last for weeks or even months in some people. Although most patients recover fully, the weakness can make it difficult to continue with normal activities or travel plans.

How Does Chikungunya Spread?

Chikungunya does not spread directly from person to person. The infection occurs when a mosquito bites a person already carrying the virus and then bites another person. Since mosquitoes are active during the day, especially early morning and late afternoon, travellers are at higher risk when outdoors at these times.

Is Chikungunya Dangerous?

While chikungunya rarely causes death, it can still be serious. Older adults, newborns, and people with existing health conditions like diabetes or heart problems may develop complications. For travellers, even a mild case can disrupt plans, cause financial strain, and lead to extended recovery periods.

How Can Travellers Protect Themselves?

If you are visiting areas where chikungunya cases are reported, taking preventive steps is crucial. Protection is always better than cure since there is no specific antiviral treatment for the infection.

Here are effective ways to reduce your risk:

• Use mosquito repellents on exposed skin
• Wear long-sleeved clothing and full-length pants
• Sleep in air-conditioned rooms or under mosquito nets
• Avoid areas with standing water such as ponds, drains, or uncovered containers
• Stay indoors during peak mosquito activity times
• Choose accommodation with window screens and proper ventilation

These preventive actions may seem simple, but they can greatly lower your chances of infection.

What Should You Do if You Develop Symptoms While Travelling?

If you develop fever and joint pain during or after your travel, do not ignore it. Seek medical care immediately. Tell your doctor about your recent travel history because this information helps in accurate diagnosis.

Doctors usually confirm chikungunya through blood tests. Treatment focuses on relieving symptoms, such as using pain relievers, staying hydrated, and resting. Early medical care can prevent complications and help you recover faster.

Difference Between Chikungunya and Dengue

Travellers often confuse chikungunya with dengue since both are mosquito-borne and share similar symptoms. However, there are key differences:

• Chikungunya causes more intense joint pain than dengue
• Dengue is more likely to cause bleeding and drop in platelet count
• Rash patterns may differ
• Recovery time is generally longer in chikungunya due to persistent joint pain

Understanding these differences helps travellers seek timely medical advice.

Do You Need a Vaccine for Chikungunya?

Currently, there is no widely available vaccine for chikungunya. Scientists are working on it, but until then, prevention through mosquito control and personal protection remains the best way to stay safe.

Why Travellers Need to Stay Alert

Travellers often move between cities and countries, which means they may unknowingly carry the infection to new places where mosquitoes are present. This is how outbreaks spread. By protecting yourself, you are not only staying safe but also helping reduce the risk of wider transmission.
