In this guide
Caribbean cruises often visit three or four countries in a week, and each has its own CDC health page. Here’s what CDC guidance has in common across many Caribbean ports, and how to check your own itinerary. Your doctor or a travel clinic can tell you what you personally need, ideally at least a month before you sail (CDC: Jamaica traveler page).
Step 1: Look up every port
CDC destination pages list recommended vaccines, disease risks and a packing list for each country. Search each port country on CDC Travelers’ Health. We use Jamaica below as a worked example; your ports may differ.
Vaccines the CDC lists (Jamaica example)
| Vaccine | What CDC says for travelers to Jamaica |
|---|---|
| Routine vaccines | Be up to date before every trip, including MMR, chickenpox, tetanus-diphtheria-pertussis, polio, flu and shingles |
| Measles (MMR) | All international travelers should be fully vaccinated. CDC has a global measles travel notice |
| COVID-19 | All eligible travelers should be up to date |
| Hepatitis A | Recommended for unvaccinated travelers aged 1 year and older |
| Hepatitis B | Recommended for unvaccinated travelers under 60 |
| Typhoid | Consider if visiting areas with poor sanitation, staying a month or more, or visiting friends or relatives |
| Yellow fever | Not recommended by CDC. Only required if arriving from a country with yellow fever risk |
Source: CDC: Jamaica. Ask your clinic how this applies to you; some vaccines need more than one dose or time to take effect.
The CDC’s cruise chapter adds a reason to check routine vaccines: outbreaks of measles, chickenpox, mumps, hepatitis A and other vaccine-preventable diseases have been reported on cruise ships, and crew vaccination policies vary by cruise line (CDC Yellow Book: Cruise Ship Travel).
Mosquitoes: dengue and Zika
CDC lists dengue and Zika for Jamaica, both spread by mosquito bites, and there’s no vaccine for most travelers. Zika can spread from a pregnant person to the baby (CDC: Jamaica). The cruise chapter notes that chikungunya and Zika both spread across the Caribbean in the last decade (CDC).
CDC bite-prevention tips include:
- An EPA-registered repellent with DEET, picaridin, oil of lemon eucalyptus (OLE/PMD), IR3535 or 2-undecanone, used as directed.
- Long sleeves and pants where practical.
- Permethrin-treated clothing (not on skin).
Pregnant or planning pregnancy? The CDC advises pregnant travelers to reconsider travel to areas with a Zika outbreak. See our guide to pregnancy and cruising rules.

Sun and heat
CDC advises sunscreen of at least SPF 15, protective clothing and shade during 10 a.m. to 4 p.m. Sun reflects off sand and water, which increases exposure. In heat, drink water, eat regularly and limit strenuous activity (CDC: Jamaica).
Food, water and beaches in port
- Follow safe food and water habits when eating ashore (CDC cruise chapter).
- Swim only in designated areas and obey lifeguards and flags.
- Avoid swallowing water when swimming, and wear shoes on beaches where there may be animal waste (CDC: Jamaica).
