Aruba Health and Vaccines: Yellow Fever Rules, Tap Water, Medical Care and Mosquitoes

Somewhere between the jet bridge and the immigration desk at the airport, a lot of travelers start wondering what they forgot: a vaccine, a document, a pill. Then they reach the beach and the next question is whether to fill the water bottle at the hotel sink. The short version is reassuring: Aruba asks for a yellow fever certificate only from travelers coming from certain countries, the tap water is excellent, and a few sensible habits cover most of the rest.

Do you need vaccines for Aruba?

Only one vaccine matters for entry, yellow fever, and it applies to travelers arriving from a select group of countries considered at risk, not to everyone. Travelers coming straight from the United States are not the target of the rule, but it helps to know how it works if your trip passes through another country first. The requirement has been in place since March 1, 2018.

What the yellow fever rule asks for

If the rule applies to you, you need proof of vaccination in the form of an International Certificate of Vaccination or Prophylaxis, also called the yellow book. You show it to immigration officers at the Department of Immigration, Security and Alarm of Aruba (IASA) before entering the island.

The shot must be given at least 10 days before you enter Aruba, so it is not something to sort out at the last minute. If you were vaccinated less than 10 years ago and still have your certificate, you do not need to be vaccinated again. Argentina is temporarily exempt from the requirement until further notice.

Who is exempt

Several cases are excused from the certificate, and they are worth reading closely if you have a long layover or a family with a baby or grandparents. The table gathers them.

Situation	Exemption
Passengers in transit through Aruba, including leaving and re-entering the airport or a cruise ship	Exempt if less than 24 hours
Passengers who passed through at-risk countries (airports or seaports) on the way to Aruba	Exempt if in transit less than 12 hours
Passengers who stayed in a country not considered at risk before entering Aruba, without developing fever	Exempt after at least 6 days there
Children	Exempt under 9 months
Adults	Exempt at age 60 and older
Immunocompromised people, people with a thymus disorder, or a history of acute hypersensitivity to a vaccine component	Exempt with an up-to-date medical waiver

Pregnant or breastfeeding women should talk with their doctor. If the doctor does not recommend the vaccine, a medical letter on official letterhead, with a stamp, is required. Aruba residents leaving the island are not required to be vaccinated for yellow fever.

Is the tap water safe in Aruba?

Yes, the tap water is safe to drink, and it has a reputation for clean taste. The island has no natural rivers or freshwater sources, so the story behind the glass is a good one: drinking water is made from seawater in a high-quality desalination process.

Where the water comes from

The desalination plant is run by W.E.B. Aruba N.V., the island’s Water and Energy Company. The water is purified, distilled and remineralized, and it meets the highest quality standard set by the World Health Organization. Locals call it sweet water, meaning fresh water, a nice phrase for something that starts out as the Caribbean Sea.

That origin explains why there is nothing to be wary of on arrival. You can drink the tap water at hotels, restaurants and homes across the island, so a glass of water with dinner or a rinse of your toothbrush needs no second thought.

Skip the plastic bottles

There is no need to buy bottled water in Aruba, and you can drink straight from the tap. Bring a reusable bottle and fill it before heading out to the beach or the drive through the dry, windy countryside. It is an easy way to stay hydrated and to cut down on single-use plastic.

That fits the island’s wider habits. Aruba banned single-use plastic bags in 2017, and in November 2019 its Parliament added plastic cups, plates, straws, stirrers, utensils and to-go containers. A refillable bottle in your beach bag is the local way of doing things.

What medical care is there?

Medical care exists on the island, but access to quality care is limited, and facilities may not meet the health and service standards you expect in the United States. Ambulance services are widely available, which is a useful thing to know if something happens on a beach or a remote road.

Paying for care

Money is the part that surprises people most. U.S. Medicare and Medicaid do not apply overseas, and most hospitals and doctors abroad do not accept U.S. health insurance. Most care providers overseas only accept cash payments, so expect to pay on the spot and sort out any reimbursement afterward.

Evacuation is the big-ticket item. If the patient’s insurance carrier authorizes it or you fund it privately, the cost of a transfer to the United States is approximately $15,000 to $25,000. Critically ill patients who need services unavailable in Aruba are transferred to neighboring countries, such as Colombia, at the patient’s expense.

Prescription medicines

If you travel with prescription medication, check with the government of Aruba to be sure it is legal there. Always carry it in its original packaging with your doctor’s prescription.

The variety of drugs sold locally is smaller than in the U.S., so you may not find all of your medications in Aruba. For most medicines you would need a local prescription, which is a good reason to bring enough of whatever you take regularly.

For divers

There is no decompression chamber in Aruba. A person suffering from decompression sickness must be medically evacuated for proper treatment, which ties back to the evacuation costs above. Divers should keep that in mind when planning their trip. Critically ill patients who need services unavailable in Aruba are transferred to neighboring countries, such as Colombia, at the patient’s expense.

What health risks should travelers know?

Mosquito-borne illness is the main one: Zika virus, dengue and chikungunya are all prevalent in Aruba. None of them has an entry requirement attached, but they are the reason a bottle of repellent belongs in your bag.

Mosquitoes

Use the mosquito repellents recommended by the U.S. Centers for Disease Control and Prevention, and sleep under insecticide-impregnated mosquito nets where they are available. Evenings on a terrace and early mornings are the moments many travelers remember being bitten, so that is when repellent earns its place.

Sun, sunscreen and the reef

Aruba is small, flat, dry and windy, and the sun is strong over open beaches and rocky coasts. The island bans sunscreens containing oxybenzone because the ingredient contributes to coral bleaching, so check the label before you pack. Aruba Aloe and Arubalife Organics make reef-safe, mineral-based sunscreens.

Wildlife and nature habits

Chasing, touching or feeding wildlife damages the island’s ecosystem and counts as unwanted behavior. So does collecting seashells from the beach and taking them home. Driving through the backlands on high-speed off-roading adventures is also unwelcome. The Natural Pool (Conchi) is reachable only by 4×4, ATV, UTV or a guided tour.

Good to know before you go

The U.S. State Department rates Aruba Level 1, ‘Exercise normal precautions,’ and says Aruba is generally a safe destination for travelers, with petty crime the main concern in popular tourist areas.

Beach attire belongs on the beaches or by the pool, not in shops and restaurants. Drivers from the U.S. should remember there are no turns on red in Aruba, and that at intersections without signs, traffic from the right has the right of way.

Speed limits are 25 miles/h in urban areas and 37 miles/h out of town unless otherwise indicated. Paying the entrance fee to Arikok National Park contributes to protecting the island’s nature.
