Prevention and Care for Climate-Related Illnesses

Common Tropical Diseases in Saint Kitts and Nevis:

• Dengue: Transmitted by the Aedes aegypti mosquito, dengue is present year-round and can cause high fever, muscle and joint pain, skin rashes, and rarely, severe hemorrhagic forms. Three out of four cases are asymptomatic, but fatigue can persist. No specific treatment or preventive vaccine, except for those with a documented prior dengue infection.
• Chikungunya: Also transmitted by Aedes aegypti and Aedes albopictus, chikungunya causes high fever and joint pain that can last for months. Atypical forms exist, with abdominal pain or rare neurological complications. No vaccine or specific treatment.
• Zika: The Zika virus also circulates in the region. It can cause fever, skin rashes, joint pain, and in pregnant women, serious complications for the fetus. No vaccine available.

Prevention Methods

Mosquito Protection:

• Use treated mosquito nets for sleeping, especially during the rainy season.
• Apply mosquito repellents containing DEET, icaridin, or lemon eucalyptus oil to exposed skin.
• Wear long clothing, particularly at dawn and dusk.
• Install mosquito screens on windows and doors.
• Eliminate standing water around homes to reduce mosquito breeding sites.

Vaccination:

• Dengue: Vaccination is only recommended for those with a proven prior infection.
• Recommended vaccines for other risks: hepatitis A and B, typhoid, polio, rabies, meningitis (consult a doctor before travel).

Care in Case of Illness

Recognizing Warning Signs:

• Sudden fever, joint or muscle pain, headache, skin rash, nausea, vomiting.
• In case of severe symptoms (bleeding, intense abdominal pain, neurological issues), seek emergency care.

Available Medical Infrastructure:

Infrastructure	Main Location	Services Offered
General Hospital	Basseterre (Saint Kitts)	Emergency, hospitalization, laboratory
Local Health Centers	Several on both islands	Primary care, consultations, pharmacy
Private Clinics	Basseterre and Charlestown	General medicine, specialized consultations

Quick Access to Emergency Care:

• Go directly to the general hospital or nearest health center.
• In case of severe symptoms, call local emergency services.
• Arrange travel insurance covering medical care and medical evacuation if needed.

Practical Recommendations for Travelers

Before Travel:

• Get a medical check-up, verify required and recommended vaccines are up to date.

During the Stay:

• Maintain good hydration (drink 2 to 3 liters of water per day).
• Favor a varied diet rich in fruits, vegetables, and protein.
• Monitor heat tolerance: avoid intense physical activity midday, wear light, breathable clothing.

After Travel:

• Monitor for symptoms suggestive of infectious diseases for several weeks.
• Consult a doctor promptly if fever, joint pain, skin rash, or digestive issues occur.

Impact of Tropical Climate on Health

High temperatures and high humidity promote dehydration and heatstroke.

Mosquito-borne diseases are more common during the rainy season, when conditions are ideal for their reproduction.

Persistent humidity can increase the risk of skin infections and digestive issues.

Adopt simple habits: drink regularly, protect yourself from the sun, monitor mosquito breeding sites, and consult quickly if suspicious symptoms appear.

List of Recommended Medical Checks:
