Cabo Verde Travel Health Guide: Malaria-Free, But the Santa Maria Stomach Bug Is Very Real

Cabo Verde is one of the few African destinations where you do not need malaria pills. The World Health Organization certified the archipelago malaria-free on January 12, 2024, making it the third country in the WHO African Region to earn that status. No vaccines are required for Americans flying in directly, and the yellow fever certificate rule only applies if you arrive from a country with yellow fever transmission risk. The actual health risk in Cabo Verde is far less exotic and far more likely to ruin your week: an unresolved foodborne and waterborne outbreak of Shigella and Salmonella centered on the Santa Maria resort strip on the island of Sal. As of March 2026, more than 1,000 confirmed and possible gastrointestinal infections have been reported in returning travelers across the EU, the UK, and the US, and the source still has not been identified. If you are packing for Cabo Verde, the antimalarial is the thing you can skip. The food and water precautions and a standby antibiotic plan are the things you cannot.

Quick Facts: Cabo Verde Health at a Glance

• Region: Ten volcanic islands (nine inhabited) in the Atlantic, roughly 350 miles off the coast of Senegal. Most US travelers land on Sal (Amílcar Cabral International) or Boa Vista, either via Lisbon or on seasonal direct service from the US East Coast.
• Malaria: None. Certified malaria-free by WHO on January 12, 2024. No antimalarial prophylaxis is needed for any island.
• Yellow fever: No yellow fever risk in the country. A vaccination certificate is required for travelers aged 1 year and older arriving from countries with risk of yellow fever transmission, which in practice means arrivals routed through Senegal or other West African hubs, not travelers flying in from the US or Europe.
• Key recommended vaccines: Routine vaccines up to date (especially MMR and Tdap), plus hepatitis A and typhoid for most travelers. Hepatitis B and rabies are case-by-case.
• The real risk: Gastrointestinal infection. A predominant Shigella outbreak strain has been detected in returning travelers since September 2022, with a persistent Salmonella strain added since 2024. Most cases stayed at the same hotel chain in the Santa Maria area of Sal.
• Second real risk: The Atlantic. Riptides, kitesurfing and windsurfing injuries, and reef scrapes send more travelers to a clinic here than any infection does.
• Medical care: Limited. The two largest hospitals are Hospital Universitário Agostinho Neto in Praia and Hospital Baptista de Sousa in Mindelo. Serious cases are frequently evacuated to Western Europe.
• Mosquito-borne illness: No malaria, but Aedes aegypti is established across the inhabited islands, and Cabo Verde has a documented history of dengue (2009) and Zika (2015 to 2016) epidemics.

Why Cabo Verde Trips Up Prepared Travelers

There is a mental shortcut that shows up constantly in travel health: people calibrate their preparation to how far away and how "tropical" a place feels, not to what is actually circulating there.

Cabo Verde sits in an awkward spot for that instinct. It is technically West Africa, which makes some travelers over-prepare, walking into a travel clinic asking for antimalarials they genuinely do not need. At the same time it looks and functions like a Canary Islands-style beach destination, with all-inclusive resorts, package flights, and swim-up bars, which makes other travelers under-prepare and treat it as a zero-risk holiday.

Both instincts miss the same thing. The single most likely way an American gets sick in Cabo Verde right now is by eating or drinking something at a resort on Sal.

That is not a guess. It is the conclusion of a multi-country outbreak investigation that has been running for more than three years.

The Santa Maria Outbreak, Explained Properly

This is the part of Cabo Verde travel health that almost no guidebook covers, so it is worth walking through carefully.

What the surveillance data shows

Between September 2022 and March 2026, health authorities in 13 EU and EEA countries plus the UK and the US reported 766 confirmed and possible cases of shigellosis in travelers returning from Cabo Verde. The country-level breakdown reported by the European Centre for Disease Prevention and Control (ECDC): the UK (263), Sweden (120), Germany (92), France (67), the Netherlands (64), Belgium (46), Denmark (45), Luxembourg (19), Czechia (14), Portugal (12), Finland (9), the US (7), Norway (5), Ireland (2), and Poland (1).

Over the same period, more than 300 additional cases of other gastrointestinal infections were reported in returning travelers, including salmonellosis, campylobacteriosis, giardiasis, cryptosporidiosis, yersiniosis, amoebiasis, and both shiga toxin-producing and enteroinvasive E. coli. That brings the combined total past 1,000 confirmed and possible cases, with new ones still being reported as of ECDC's March 18, 2026 epidemiological update.

Two details make this outbreak unusual rather than routine.

First, laboratory testing has identified a single predominant Shigella outbreak strain in returning travelers going all the way back to September 2022, and a persistent Salmonella Enteritidis strain since 2024. Genomically related bugs turning up in travelers year after year is the signature of a persistent source, not a series of unrelated food-handling slips.

Second, the epidemiology points somewhere very specific. Based on the available case information, most affected travelers stayed at the same hotel chain in the Santa Maria region on the island of Sal. The UK Health Security Agency's late-2025 investigation found much the same pattern: of 137 confirmed Shigella sonnei cases identified since October 2025, 116 reported international travel and 109 of those had been to Cabo Verde, mostly to Santa Maria and Boa Vista.

The source of infection has still not been identified. ECDC's current assessment is that transmission is most likely food-borne or water-borne, with some person-to-person spread also plausible, and that the likelihood of a traveler picking up Shigella or another gastrointestinal pathogen in the Santa Maria area remains moderate. Additional cases are expected until the source is found and controlled.

What this actually means for your trip

It does not mean cancel. Cabo Verde receives hundreds of thousands of visitors a year and the overwhelming majority come home fine. It means treat Sal and Boa Vista resort dining the way you would treat street food in a high-risk country, which is precisely the opposite of how most people behave inside an all-inclusive.

The all-inclusive buffet is the specific problem. Buffets hold food at ambiguous temperatures for long stretches, mix in a lot of raw and ready-to-eat items, and involve hundreds of hands touching shared serving utensils. Shigella has a famously low infectious dose, meaning it takes very few organisms to make you sick, which is exactly why it spreads efficiently in that environment.

ECDC's traveler recommendations for this outbreak are blunt and worth following literally:

• Practice strict hand hygiene, especially before eating and after using the toilet.
• Eat well-cooked food served hot.
• Avoid ready-to-eat items, including unwashed fruit and vegetables, salads, and anything containing ice.
• Drink bottled or boiled water.
• If diarrhea (including bloody diarrhea), fever, or stomach cramps develop during or after travel, seek medical attention promptly.

That last line matters more than it looks. Shigellosis is not garden-variety traveler's diarrhea, and the treatment decision is different.

Shigella Is Not Ordinary Traveler's Diarrhea

Most traveler's diarrhea is watery, self-limited, and gets better with fluids, rest, and time. Shigellosis behaves differently often enough that you should know the difference before you are lying in a hotel room trying to decide what to do.

Signs that suggest something more than a routine bug:

• Blood or visible mucus in the stool
• Fever, particularly above 101°F (38.3°C)
• Severe cramping with urgent, frequent, small-volume stools
• Symptoms that are worsening rather than plateauing after 24 hours
• Signs of dehydration: minimal urination, dizziness on standing, dry mouth

Incubation is typically one to three days after exposure, which means a lot of travelers develop symptoms on the flight home or in the first days back, and never connect it to the trip.

Two treatment points worth knowing:

Loperamide (Imodium) is not the right tool for bloody, febrile diarrhea. Slowing the gut down when an invasive bacterial infection is present can prolong illness. For watery, non-febrile traveler's diarrhea it is reasonable. For dysentery-type symptoms it is not the first move, and it should never be used alone in that setting.

Antibiotic choice matters, and the resistance picture is genuinely mixed. Shigella globally has become alarmingly resistant, with extensively drug-resistant strains now well documented in international surveillance. The encouraging piece of news specific to this outbreak is that UKHSA's genomic analysis of the current Cabo Verde-linked strain found no resistance determinants against the antimicrobials commonly used to treat traveler's diarrhea. That is a real advantage, and it argues for carrying a standby antibiotic rather than assuming nothing will work.

For most travelers headed to Cabo Verde, azithromycin is the more sensible standby than ciprofloxacin, both because of broad fluoroquinolone resistance in Shigella worldwide and because azithromycin covers the other common bacterial causes of traveler's diarrhea well. This is a conversation to have with a clinician before you leave, not a decision to make from a hotel bed with spotty wifi. Our guide to azithromycin for travel covers how it is dosed and when it is the right call.

Ready to sort your Cabo Verde prep? Start with a free destination health check. It takes a few minutes, and a Wandr clinician reviews your itinerary and tells you what you actually need, including whether a standby antibiotic makes sense for your trip. If it does, the prescription is called in to your local pharmacy for pickup before you fly.

The Malaria Story: Why You Can Skip the Pills

Cabo Verde's malaria elimination is a genuinely remarkable public health story, and it changes your packing list.

WHO certified Cabo Verde malaria-free on January 12, 2024. Certification is not a formality: it is WHO's official recognition that a country has proven, with rigorous and credible evidence, that indigenous malaria transmission has been interrupted nationwide for at least three consecutive years. Cabo Verde joined Mauritius (certified in 1973) and Algeria (2019) as only the third country in the WHO African Region to reach that bar.

Practical translation: no Malarone, no doxycycline, no tafenoquine, no mefloquine. If a clinic recommends an antimalarial for a Cabo Verde beach holiday, that recommendation is out of date.

This is one of the reasons Cabo Verde has become an interesting alternative for travelers who want a West Africa-adjacent trip without the pre-trip medication load. If you are weighing it against a mainland destination, our guides to Senegal and Morocco show how different the preparation looks.

But mosquito bites still matter here

Malaria-free is not mosquito-free, and this is where a lot of travelers over-correct.

Aedes aegypti, the daytime-biting mosquito that transmits dengue, Zika, chikungunya, and yellow fever, is established across Cabo Verde's inhabited islands. The archipelago has a real arbovirus history: a large dengue outbreak in 2009 that was the biggest recorded in Africa at the time, and a Zika epidemic in 2015 and 2016 that made Cabo Verde the first African country to declare one, including confirmed cases of microcephaly.

That history does not mean an outbreak is underway during your trip. It does mean the vector is present and capable, so basic bite prevention is worth the minor effort:

• Use an EPA-registered repellent containing DEET (20% to 30%) or picaridin (20%) during daylight hours, since Aedes bites in the day
• Keep air conditioning running or screens closed in the room
• Reapply after swimming, which people reliably forget at a beach resort

Travelers who are pregnant or trying to conceive should specifically discuss Zika risk with a clinician before booking, given Cabo Verde's documented history.

Vaccines That Actually Matter for Cabo Verde

Nothing is required for entry from the US. That is different from nothing being recommended.

A note on the yellow fever certificate, because this trips people up: if you fly Boston to Lisbon to Sal, you do not need it. If you build a West Africa itinerary that puts you in Dakar or Accra before Cabo Verde, you do. The vaccine must be given at least 10 days before arrival, and since July 2016 a completed International Certificate of Vaccination or Prophylaxis is valid for life, with no booster required.

Need a vaccine before you go? Wandr books your travel vaccine appointment at a partner pharmacy near you. Pick a Walgreens location and a time, and the pharmacist administers the vaccine on-site. Book a vaccine appointment without a separate doctor's visit.

Island by Island: What Changes Where

Cabo Verde is not one destination. The health considerations shift meaningfully between islands.

Sal. The main tourist gateway and the epicenter of the current gastrointestinal outbreak, specifically the Santa Maria resort strip in the south. Flat, dry, windy, and built around beach and watersports tourism. If you are staying here, the food and water precautions above are not optional advice, they are the plan. Sal is also the kitesurfing capital of the archipelago, which brings its own injury profile.

Boa Vista. The second resort island, also named in UKHSA's case investigation. Enormous dunes, long empty beaches, and a small handful of large all-inclusives. Same precautions as Sal. Medical infrastructure is thinner here than on Sal, and thinner on both than on Santiago.

Santiago. The largest island and home to Praia, the capital, and Hospital Universitário Agostinho Neto, the country's main referral hospital. If something serious happens on a smaller island, this is often where you get moved first. More of a working island than a resort one, with more street food exposure and, correspondingly, a stronger case for the typhoid vaccine.

São Vicente. Mindelo is the cultural capital, with Hospital Baptista de Sousa, the second-largest hospital in the country. Carnival in February draws crowds, and crowds mean respiratory and gastrointestinal transmission both go up.

Fogo. Dominated by Pico do Fogo, an active volcano rising to roughly 2,829 meters (9,281 feet). The summit hike is a serious day: steep volcanic scree, no shade, and a real ankle and fall risk. True altitude sickness is uncommon at this elevation for people who sleep near sea level, but rapid exertion at altitude in heat with poor hydration produces headaches and nausea that feel very similar. Bring far more water than you think you need. Volcanic activity is monitored, and eruptions in 1995 and in 2014 to 2015 caused evacuations, so check current advisories before planning a climb.

Santo Antão. The hiking island, reached by ferry from São Vicente. Spectacular ribeira valley trails, steep exposed terrain, and limited medical facilities. Evacuation from a trail here is slow. This is the island where travel insurance with evacuation coverage stops being theoretical.

The Non-Infectious Risks Nobody Plans For

For most Cabo Verde travelers, the odds of ending up in front of a clinician for something that is not an infection are higher than the reverse.

The Atlantic. This is not the calm Caribbean. Strong currents, powerful shore break, and riptides are common on many beaches, and lifeguard coverage is inconsistent. Beaches that look inviting can have serious undertow.

Wind sports. Sal and Boa Vista are world-class kitesurfing and windsurfing destinations, which means shoulder injuries, lacerations, and the occasional fracture. Confirm that your travel insurance actually covers the activity you booked, since many standard policies exclude kitesurfing as a hazardous sport.

Sun and dehydration. Cabo Verde sits at about 16 degrees north latitude with persistent trade winds that mask how much sun you are absorbing. The wind is the trap: you do not feel yourself burning or sweating. Reef-safe SPF 30 or higher, reapplied, plus deliberate water intake.

Harmattan dust. Between roughly November and March, Saharan dust (locally called bruma seca) can blanket the islands, reducing visibility and triggering asthma and sinus symptoms. If you have reactive airways, bring your inhaler and do not assume you can buy a replacement locally.

Road and scooter injuries. Roads on the smaller islands are rough, rentals often come without helmets, and aluguer shared-taxi vans are informal. This is a standard but underrated cause of serious traveler injury.

Medical Care and Evacuation: The Part That Costs Money

The US State Department describes medical facilities in Cabo Verde as limited. Local pharmacies are widespread but some medications are in short supply or simply unavailable, and public clinics can lack basic resources and supplies. Medical staff may speak little or no English, and Portuguese or Cape Verdean Creole will be the working languages.

For anything genuinely serious, evacuation is a realistic scenario, and Western Europe is a frequent destination for it. An air ambulance from the mid-Atlantic to Lisbon is not a modest bill.

This makes Cabo Verde one of the clearer cases for travel insurance that specifically includes emergency medical evacuation and repatriation, not just trip cancellation. Check that the policy covers:

• Emergency medical evacuation and repatriation, with a coverage limit that reflects a transatlantic flight
• Any adventure activities you actually plan to do, particularly kitesurfing, windsurfing, and volcano trekking
• Direct payment to providers rather than reimbursement only, since many facilities want payment up front

Compare travel insurance options that include emergency medical evacuation before you book. On a small-island destination with limited tertiary care, this is the coverage that matters most.

Your Cabo Verde Health Timeline

Four to six weeks before departure

• Complete a free destination health check so a clinician can review your specific islands and activities
• Confirm routine vaccines, especially MMR and Tdap
• Get hepatitis A and typhoid if you are not already covered, since both need lead time
• Get yellow fever only if your routing takes you through a yellow fever risk country, and remember the 10-day rule
• Buy travel insurance with medical evacuation coverage while cancellation benefits are still available to you

Two weeks before

• Fill any standby prescriptions, including an antibiotic if your clinician agrees one is warranted, and oral rehydration salts
• Pack EPA-registered repellent, high-SPF reef-safe sunscreen, and a small hand sanitizer for buffet lines
• Check ECDC and CDC pages for updates on the Cabo Verde gastrointestinal outbreak, which is still evolving
• Save the address and phone number of the nearest hospital to your resort, and confirm what your insurer requires you to do before seeking care

The week of and during your trip

• Bottled or boiled water only, including for brushing teeth if you want to be strict
• Hot, freshly cooked food. Skip buffet salads, cut fruit, and anything with ice
• Hand hygiene before every meal, which is the highest-yield single habit against Shigella
• Daytime repellent, reapplied after swimming
• If you develop bloody diarrhea, fever, or severe cramping, seek care rather than waiting it out

After you get home

If you develop diarrhea, fever, or abdominal symptoms within a week or two of returning, tell your clinician specifically that you traveled to Cabo Verde. ECDC has advised healthcare providers to be alert to gastrointestinal infections in travelers returning from Cabo Verde and to ensure appropriate diagnostic sampling. That one sentence from you changes what gets tested and how quickly you get the right treatment. It also feeds the surveillance that will eventually pin down the source.

Frequently Asked Questions

Do I need malaria pills for Cabo Verde? No. WHO certified Cabo Verde malaria-free on January 12, 2024, after verifying that indigenous transmission had been interrupted nationwide for at least three consecutive years. No antimalarial prophylaxis is recommended for any island. Bite prevention is still worthwhile because Aedes mosquitoes that transmit dengue and Zika are present.

Is the Shigella outbreak in Cabo Verde over? No. As of ECDC's March 18, 2026 update, new cases were still being reported and the source had not been identified. More than 1,000 confirmed and possible gastrointestinal infections have been reported in returning travelers since September 2022. ECDC assesses the likelihood of infection for travelers visiting the Santa Maria area of Sal as moderate.

Which islands are affected by the outbreak? Most reported cases stayed in the Santa Maria region on the island of Sal, and UK investigators also identified cases linked to Boa Vista. Both are the primary resort islands. Basic food and water precautions are sensible everywhere in the archipelago.

Do I need a yellow fever certificate for Cabo Verde? Only if you are aged 1 year or older and arriving from a country with risk of yellow fever transmission, which typically means a West African routing such as Senegal. There is no yellow fever risk within Cabo Verde itself, and travelers flying directly from the US or Europe do not need the certificate. The vaccine must be administered at least 10 days before arrival, and certificates issued since July 2016 are valid for life.

What vaccines are recommended for Cape Verde? Routine vaccines up to date, particularly MMR and Tdap, plus hepatitis A and typhoid for most travelers. Hepatitis B and pre-exposure rabies are considered based on trip length, activities, and how far you will be from medical care.

Should I bring antibiotics for traveler's diarrhea in Cabo Verde? For many travelers to Sal and Boa Vista, carrying a standby antibiotic is a reasonable plan given the ongoing outbreak, and UKHSA genomic testing found the current outbreak strain does not carry resistance to the antimicrobials commonly used for traveler's diarrhea. Azithromycin is generally the more sensible choice than ciprofloxacin because of global fluoroquinolone resistance in Shigella. This should be decided with a clinician who knows your history, not self-prescribed.

Can I drink the tap water in Cabo Verde? Treat it as not safe to drink. Most fresh water on the islands comes from desalination and distribution quality varies. Given the active waterborne outbreak, bottled or boiled water is the right default, including for ice and, if you want to be cautious, brushing your teeth.

Is Cabo Verde safe for pregnant travelers? Cabo Verde had a Zika epidemic in 2015 and 2016 with confirmed microcephaly cases, and the Aedes aegypti vector remains established. Anyone pregnant or planning pregnancy should discuss current Zika risk with a clinician before booking, along with the fact that dehydrating gastrointestinal illness is a bigger deal in pregnancy and that medical facilities are limited.

How good is medical care in Cabo Verde? Limited. The largest facilities are Hospital Universitário Agostinho Neto in Praia and Hospital Baptista de Sousa in Mindelo, with smaller health centers and private clinics elsewhere that vary widely in staffing and equipment. Serious cases are often evacuated to Western Europe, which is why medical evacuation insurance matters here more than at most beach destinations.

When is the best time to visit Cabo Verde from a health standpoint? The climate is stable year-round. The main seasonal health variable is Saharan dust (bruma seca), heaviest roughly November through March, which can aggravate asthma and sinus conditions. The brief rainy season, generally August through October, can produce more standing water and therefore more mosquito activity.

The Bottom Line

Cabo Verde has done something almost no African country has managed, and it means you get to leave the antimalarials at home. That is a genuine advantage and worth understanding correctly.

What replaces it is less glamorous. An unresolved, multi-year outbreak of Shigella and Salmonella tied to the resort strip on Sal is the single most likely thing to make an American traveler sick here, and the countermeasures are unglamorous too: bottled water, hot food, no buffet salads, obsessive hand hygiene, and a plan for what to do if bloody diarrhea and fever show up at 2 a.m. in a hotel room.

Get that plan in place before you fly, and Cabo Verde is one of the easier long-haul beach trips an American can take.

Start your free destination health check. Tell us which islands you are visiting and what you plan to do there, and a Wandr clinician will tell you exactly what you need. Prescriptions are called in to your local pharmacy for pickup, and vaccine appointments are booked at a partner pharmacy near you.
