St. Helena travel health
Sources checked
Overview
St. Helena is a small, remote British Overseas Territory with basic local hospital services and limited specialist care. Travellers should plan for constrained access to advanced medical treatment and possible medical evacuation; carry comprehensive travel and evacuation insurance, any regular medicines, and documentation of vaccinations. Regulations about vaccine certificates (for example yellow fever) are conditional and should be checked with official authorities before travel.
Health system and evacuation
St. Helena provides general medical care on-island but advanced care or specialist evacuation (to South Africa or the UK) may be required for serious illness; some visas/entry permits and departure arrangements reference minimum medical-evacuation insurance. Check local healthcare capacity and ensure evacuation cover before you travel (GOV.UK travel health, St Helena eVisa FAQ).
Vaccinations and entry requirements
Distinguish legally required certificates from vaccines commonly advised for travellers. Below are the main topics relevant for most visitors; your personal needs depend on itinerary, health, age and prior vaccination.
Routine vaccines
Make sure you are up to date with routine immunizations (MMR, diphtheria–tetanus–pertussis, polio, influenza, varicella and shingles where indicated). These are the foundation of travel protection and are widely recommended for all international travellers. CDC Travelers’ Health: Saint Helena.
Hepatitis A and B
CDC recommends Hepatitis A vaccination for unvaccinated travellers aged ≥1 year going to Saint Helena; Hepatitis B vaccination is also advised for travellers who might have sexual contact with new partners, require medical procedures, or have other exposure risks. Discuss timing if you need accelerated schedules before departure. CDC Travelers’ Health: Hepatitis A & B.
Rabies
Dog rabies is not common on St. Helena, but exposures can occur. Rabies post‑exposure vaccines and immunoglobulin may be limited or unavailable locally; consider pre‑exposure vaccination if your itinerary includes work or activities with frequent animal contact or if prompt access to post‑exposure care will be difficult. CDC Travelers’ Health: Rabies.
Yellow fever (certificate rules)
International rules for yellow fever certificates are conditional: a certificate is required for travellers aged ≥1 year arriving from countries with risk of yellow fever transmission. This is a legal entry requirement in such arrival circumstances, not a blanket recommendation for all visitors. The St. Helena Health Services has occasionally offered limited yellow‑fever vaccination clinics for travellers who need onward connections (for example via Accra); if you expect to transit or arrive from a country with yellow fever risk, arrange vaccination at an authorised clinic at least 10 days before travel or confirm whether a certificate is required for your route. WHO Disease Outbreak News (rules on YF certificates), CDC Saint Helena guidance, St Helena Government: yellow fever vaccine clinic.
Entry permits and insurance
Short-term entry permits (eVisa/permit) are common; application guidance and permit conditions can include proof of medical/evacuation insurance. Confirm passport validity, visa/eVisa requirements and insurance amounts with St. Helena Immigration or your carrier before departure. St Helena eVisa FAQ, GOV.UK entry requirements.
Other health risks
Evidence-based risks for travellers to St. Helena are relatively few; take routine precautions for food, water, insects and environmental hazards. Specific items below are supported by public-health guidance.
Malaria
There is no ongoing malaria transmission on St. Helena; antimalarial prophylaxis is not routinely recommended for mainland St. Helena. (Ascension Island and Tristan da Cunha have separate advice.) If your trip includes other countries with malaria risk, follow destination‑specific prophylaxis guidance. CDC malaria country table.
Rodent exposures and hantavirus
During May–June 2026 a multi‑country cluster of Andes‑strain hantavirus infections was linked to passengers and crew of the expedition vessel MV Hondius; WHO and other agencies led contact tracing and management. WHO declared the event closed on 2 July 2026, and public‑health authorities assessed ongoing population risk as very low; nevertheless avoid rodent‑infested areas, do not handle rodent droppings, and seek medical advice if you develop fever or acute respiratory symptoms after travel. Travellers who were aboard implicated vessels or had close contact with confirmed cases should follow public‑health instructions. WHO Disease Outbreak News (MV Hondius), CDC Health Advisory (HAN), St Helena Government update.
Leptospirosis and environmental risks
Leptospirosis can be transmitted through contaminated fresh water and soil; avoid swimming or wading in floodwater or streams that might be contaminated and protect skin breaks. Standard wound care, insect‑bite avoidance, sun protection and careful food/water choices reduce common travel illnesses. CDC: stay healthy guidance.
Insect control and disinsection
Although St. Helena is not a yellow‑fever transmission area, vector control matters for some routes and cargo; inbound aircraft must follow the island’s disinsection policy. Use insect repellent (DEET/icaridin), protective clothing and bed nets where appropriate. St Helena Airport: disinsection policy.
Availability of medicines and specialist services
Some vaccines and specific medicines (for example rabies immunoglobulin or certain specialist treatments and a hyperbaric chamber for diving injuries) may be unavailable locally. If you need regular prescriptions, bring an adequate supply and written prescriptions. Consider evacuation-capable insurance and check the hospital’s scope of services before you leave. GOV.UK: healthcare on St. Helena, St Helena Government: medical costs policy.
Current health alerts
Only active, well‑documented developments are listed below.
Andes hantavirus cluster linked to MV Hondius (May–July 2026)
A cluster of Andes‑virus hantavirus cases was identified among passengers and crew of the expedition vessel MV Hondius in May 2026. International agencies carried out contact tracing and case management; WHO closed the event on 2 July 2026 after monitoring completed and found no ongoing transmission. For travellers this means: if you were on the MV Hondius or had close contact with a confirmed case, follow public‑health instructions and seek clinical assessment for fever or respiratory illness; for other visitors the public‑health risk in St. Helena is currently assessed as very low. WHO DON 2 July 2026, CDC HAN notice (May 2026), St Helena Government update (6 May 2026).
Before you travel
Plan early: get routine and destination vaccines, confirm any conditional certificate requirements for your exact travel route, obtain travel and medical‑evacuation insurance, bring prescriptions and a basic first‑aid kit, and pack insect repellent and sun protection.
Practical checklist
Visit a travel‑health clinic at least 4–8 weeks before departure to review vaccinations (including Hep A/B and any needed pre‑exposure rabies), discuss yellow‑fever certificate rules for your route, and review malaria advice only if you plan travel to other malaria‑risk countries. Carry proof of insurance and an up‑to‑date list of medicines and medical contacts. CDC Saint Helena travel page, St Helena eVisa FAQ.
