Puerto Rico for Couples: Vaccines, Dengue, Night Driving and CDC Advice

Puerto Rico is a US territory with the charm of Old San Juan and very accessible beaches, which is why it is often a first Caribbean trip for couples. We have not verified any lifestyle venue or event on the island with an official website, so this guide focuses on health and logistics using two sources we consulted on 7 November 2026: the US CDC destination page (last reviewed 25 August 2026) and the UK FCDO page on entry to the USA.

Vaccines and CDC notices

The CDC places the island at Level 1, "practice usual precautions". It recommends hepatitis A vaccination for unvaccinated travellers aged 1 and over and hepatitis B for unvaccinated travellers of all ages. With measles rising in many countries, it asks that you be fully vaccinated with MMR. Consider typhoid vaccination if you will visit areas with poor sanitation, stay a month or more, or visit friends or relatives. Yellow fever is neither recommended nor required. For adults with certain activities, such as new sexual partners or commercial sex venues, the CDC recommends mpox vaccination: a relevant point for couples with an open lifestyle, worth discussing with a doctor before travelling. Keep routine vaccines and COVID-19 up to date.

Mosquitoes and water

Dengue and Zika are mosquito-borne: use repellent and covering clothing. Zika can pass from an infected pregnant woman to her baby. The CDC also warns about leptospirosis and melioidosis after heavy rain, advising you to avoid floodwater and contact with contaminated soil or fresh water, and about schistosomiasis, advising against swimming in unchlorinated fresh water such as lakes, ponds and rivers. It also lists hantavirus (avoid rodents), tuberculosis and African tick-bite fever (prevent tick bites).

Roads and animals

Motor vehicle crashes are a major risk and street lighting in parts of the island may be poor, so avoid night driving. Rabies is not common in dogs but occurs in some wildlife and bats; if bitten or scratched, wash the wound and see a doctor promptly.

Entry for British visitors

The FCDO explains that British citizens need an ESTA or a US visa, a passport valid for the length of the stay, and that a valid authorisation does not guarantee admission. You may not qualify for ESTA if you have been arrested, have a criminal record or were previously refused entry, or if you have been in certain countries since 2011 or in Cuba since 12 January 2021. That page does not mention Puerto Rico specifically, so confirm with the official US source if your case is unusual. Other nationalities should check with their own government.
