🇰🇲 Comoros
Is the Comoros Safe for Travel?
The Union of the Comoros is an archipelago nation nestled in the northern Mozambique Channel between Madagascar and the East African coast. Known as the Perfume Islands for their fragrant ylang-ylang and vanilla plantations, the archipelago consists of three primary islands: Grande Comore (Ngazidja), Mohéli (Mwali), and Anjouan (Nzwani).
Comoros offers dramatic volcanic scenery and marine biodiversity, but travelers face practical and logistical challenges. While violent crime against foreigners is uncommon, travelers must contend with rudimentary medical facilities, periodic civil unrest in Moroni, hazardous maritime transit on small boats, active volcanic hazards from Mount Karthala, and endemic malaria and cholera risks.
Things to Know Before You Go
Essential Medical Evacuation Insurance
Medical care in Comoros is extremely basic. Hospitals lack emergency medications, sterile supplies, blood banks, and advanced surgical gear. Ensure your travel insurance covers emergency medical air evacuation to Reunion, Mauritius, or Kenya.
Avoid Small Boat (Kwassa-Kwassa) Crossings
Never travel between islands on small, overloaded open motorboats known locally as kwassa-kwassa. Ocean currents in the Mozambique Channel are strong, sudden squalls occur frequently, and maritime rescue capacity is virtually absent. Use scheduled domestic flights (AB Aviation or R Komor) or certified passenger ferries.
Mandatory Malaria Prophylaxis
Malaria is widespread across all three islands. Take prescription prophylaxis (such as atovaquone-proguanil or doxycycline), sleep under mosquito nets, and use DEET-based insect repellent.
Cholera and Safe Drinking Water
Comoros experiences recurrent cholera outbreaks. Drink only factory-sealed bottled water with intact seals or vigorously boiled water. Avoid ice, street food, and unpeeled fruits.
Respect Conservative Islamic Customs
Comoros is a conservative Islamic society. Dress modestly when outside beach hotels: keep shoulders and knees covered, avoid public displays of affection, and respect alcohol restrictions outside tourist establishments.
Personal Security & Public Safety
Crime, unrest, and the public-order risks that shape day-to-day safety.
Traveler Situations & Contexts
How risk shifts for solo travelers, nighttime transit, LGBTIQ+ travelers, and public transport.
Solo Travel
Independent travel in Comoros requires self-reliance and French communication skills, as English is rarely spoken outside international agencies. Shared taxis (taxis-brousse) are the main mode of road transport but are crowded and drive erratically.
Solo Female Travel
Women traveling unaccompanied should expect curious attention. Dressing modestly (wearing long skirts or loose trousers and covering shoulders) is essential for smooth interactions. Avoid walking alone after dark in urban neighborhoods of Moroni or Mutsamudu.
Political Gatherings and Demonstrations
Spontaneous protests and strikes can occur in Moroni, particularly surrounding political elections or economic grievances. Avoid all public political gatherings, as police have used tear gas to disperse crowds.

Environmental & Natural Hazards
Weather extremes, seismic activity, and natural disaster exposure.
Mount Karthala Volcano
Mount Karthala on Grande Comore is an active shield volcano standing over 2,300 meters above sea level. It has erupted numerous times in recent decades, releasing ash clouds, seismic tremors, and toxic volcanic gases that can contaminate drinking water cisterns. Check with local guides and park authorities before attempting summit treks.
Tropical Cyclones & Heavy Rains
Between December and April, tropical depressions and cyclones can strike the archipelago, causing flash floods, mudslides on steep volcanic slopes, and disruptions to domestic flights and sea ferries.
Health & Diseases in the Comoros
Strict tripartite separation: endemic disease threats, recommended travel vaccines, and legally mandatory entry certificates.
Healthcare facilities across the archipelago are severely limited. Even in the capital, Moroni, pharmacies often run out of basic antibiotics and medical consumables.
Endemic Malaria
Plasmodium falciparum malaria is present throughout the country. Symptoms can appear within days of exposure or weeks after returning home. Any fever during or after your trip requires immediate medical evaluation and diagnostic testing.
Cholera & Enteric Diseases
Water supply systems on the islands are vulnerable to contamination. Cholera, typhoid, and hepatitis A spread through contaminated food and water. Wash hands frequently with soap, use alcohol hand rub, and eat only hot, freshly prepared meals.
Dengue and Chikungunya
Daytime-biting Aedes mosquitoes transmit dengue and chikungunya. Take continuous mosquito bite prevention measures, including repellent and loose light clothing.
Mandatory Yellow Fever Certificate
A yellow fever vaccination certificate is required for travelers aged 9 months or older arriving from countries with risk of yellow fever transmission, or who have spent more than 12 hours in transit through an endemic country airport.
Recommended Vaccines
Health authorities recommend vaccination against Hepatitis A, Typhoid, Tetanus, and routine childhood vaccines. An oral cholera vaccine is recommended for travelers visiting areas with active transmission or residing in communities with compromised sanitation.
Endemic Disease Risks
Vector-borne and water-borne pathogens present in territory.
Recommended Vaccinations
Advised medical prophylaxis for general travelers.
Worth considering, depending on your trip.
Mandatory Entry Regulations
Legally enforced entry documentation required at border control.
Government Advisory Comparison
How the major government advisories compare, and where they genuinely disagree rather than just draw the boundary differently.
International government advisories share a consistent assessment of Comoros, advising travelers to exercise increased caution.
The United States, the UK Foreign Office, and Germany advise increased vigilance, citing limited emergency medical services, civil protest risks, and transport hazards. Canada advises a high degree of caution, highlighting the fragility of public infrastructure. All advisories warn travelers against boarding unlicensed open boats between islands, recommend comprehensive air ambulance insurance, and advise avoiding political demonstrations in Moroni.
