Travel Health Guide: Dominican Republic

Resort vs. Adventure Travel

If you’re staying at an all-inclusive resort in Punta Cana or Puerto Plata, your health risks are lower but not zero. Hepatitis A vaccination remains essential regardless of your accommodation. The hepatitis A virus is transmitted through contaminated food and water and can infect travelers even at upscale resorts where kitchen hygiene lapses.

Adventure travelers, eco-tourists, and those visiting family in rural areas face significantly higher exposure to food and waterborne illness, mosquito-borne diseases, and rabies risk. A personalized consultation at Peel Travel Clinic ensures your protection is matched to your actual itinerary.

Zika Virus History and Current Risk

The Dominican Republic experienced significant Zika virus transmission during the 2015–2016 outbreak. Zika is spread by the same Aedes aegypti mosquito that carries dengue and chikungunya. While active outbreak intensity has declined, the virus remains present in the Caribbean and cases are still reported periodically.

Pregnant travelers or those planning pregnancy should consult Dr. Saldanha before booking travel to the Dominican Republic. Zika infection during pregnancy is associated with serious birth defects including microcephaly. No vaccine is currently available; prevention depends entirely on avoiding mosquito bites.

Malaria — Know Your Risk Zone

The Dominican Republic is one of the few Caribbean islands with any malaria transmission, though risk is geographically limited. Malaria is primarily found in rural, low-lying areas near the Haitian border — particularly in the provinces of Dajabón, Elías Piña, and Bahoruco. Resort destinations such as Punta Cana, La Romana, and the tourist-focused north coast are considered low risk.

Travelers venturing into rural southwestern regions or crossing into Haiti should discuss malaria prophylaxis during their consultation. The species present is Plasmodium falciparum, the most severe form of malaria, and it is chloroquine-sensitive in this region.

Cholera — Historical Risk and Water Safety

The Dominican Republic and neighboring Haiti experienced a major cholera outbreak beginning in 2010 following the Haitian earthquake. Cholera is transmitted through contaminated water and food. While the outbreak has been largely controlled, cholera risk remains in areas with poor sanitation and limited clean water access, particularly near the Haitian border and in some rural communities.

Water safety is important throughout the country: do not drink tap water, avoid ice unless you are certain it was made from purified water, and be cautious about salads and raw vegetables washed in tap water. Dukoral (oral cholera vaccine) may be recommended for certain travelers — discuss your itinerary with us.

Dengue & Mosquito Protection

Dengue fever is endemic in the Dominican Republic and circulates year-round, with higher transmission during the rainy season (May through November). There is currently no dengue vaccine widely available in Canada. Mosquito prevention is critical: use DEET-based repellent (at least 20–30% DEET), wear long sleeves and pants at dawn and dusk, and sleep in air-conditioned rooms or under bed nets.

Chikungunya is also present in the Dominican Republic and is spread by the same mosquito as dengue. Symptoms are similar but joint pain may be more severe and prolonged.

Water Safety and Traveler’s Diarrhea

Traveler’s diarrhea is the most common illness affecting visitors to the Dominican Republic. The main causes are bacteria such as E. coli transmitted through contaminated food and water. Avoid tap water, ice from unknown sources, raw vegetables, and unpeeled fruit. Street food carries higher risk than restaurant food.

We can prescribe standby antibiotics (typically azithromycin or ciprofloxacin) to carry during your trip for self-treatment if diarrhea becomes severe. Oral rehydration salts are also recommended, especially if traveling with children.

Recommended Vaccines — Summary

Based on your destination and activities, Dr. Saldanha typically recommends the following for Dominican Republic travel:

• Hepatitis A — Strongly recommended for all travelers
• Typhoid — Recommended for those eating outside resort environments
• Routine boosters — Ensure tetanus-diphtheria, MMR, and COVID-19 are current
• Hepatitis B — Recommended for extended stays or potential medical exposure abroad
• Rabies — Consider for adventure travelers, eco-tourists, or those with expected animal contact
• Cholera (Dukoral) — May be recommended for travelers going to high-risk rural areas or near the Haitian border

When to Get Vaccinated

Book your consultation 2–4 weeks before departure. Many vaccines provide protection within days and can be administered during a single appointment.
