Quick Answer
Malaria is not confined to Africa. Travellers may also face risk in parts of Asia, Central and South America, the Caribbean, the Middle East and the Pacific. Because risk can vary within the same country, travellers should obtain itinerary-specific advice, prevent mosquito bites and take prescribed antimalarial medicine correctly.
Malaria is often associated with safari holidays and travel to sub-Saharan Africa. Although Africa carries most of the global malaria burden, it is not the only region where travellers can become infected.
Malaria transmission also occurs in parts of South Asia, Southeast Asia, Latin America, the Caribbean, the Middle East and the Pacific. Risk can even differ between cities, rural districts, coastal areas and high-altitude regions within the same country.
This is why checking a country name alone is not enough. Your exact route, travel dates, accommodation, activities, medical history and length of stay all affect your personal malaria risk.
For UK travellers, understanding malaria outside Africa is particularly important before family visits, backpacking trips, business travel, volunteering, cruises, adventure holidays and longer stays abroad.
Key Takeaways
- Malaria occurs outside Africa, including in parts of Asia, Latin America, the Caribbean, the Middle East and the Pacific.
- Risk is not always uniform across an entire country.
- Rural, forested and lower-altitude areas may carry different risks from major cities or tourist resorts.
- One infected mosquito bite can transmit malaria.
- Antimalarial tablets reduce risk but do not provide complete protection.
- Mosquito-bite prevention remains necessary, even when taking malaria tablets.
- Travellers visiting friends and relatives may underestimate their risk after living in the UK.
- Fever or flu-like symptoms during travel or after returning from a malaria-risk area require urgent medical advice.
What Is Malaria?
Malaria is a potentially life-threatening infection caused by Plasmodium parasites and usually spread through the bite of an infected female Anopheles mosquito.
Once the parasite enters the body, it travels to the liver before infecting red blood cells. This blood-stage infection produces symptoms such as fever, chills, headache, muscle pain and fatigue.
Five main Plasmodium species can infect humans:
- Plasmodium falciparum: The most dangerous species and the main cause of malaria deaths worldwide.
- Plasmodium vivax: Particularly important outside sub-Saharan Africa and capable of causing later relapses.
- Plasmodium ovale: Can remain dormant in the liver and cause illness months later.
- Plasmodium malariae: May occasionally present long after the original infection.
- Plasmodium knowlesi: A zoonotic form associated mainly with parts of Southeast Asia.
Malaria cannot be confirmed or excluded from symptoms alone. A blood test is required.
Is Malaria Only Found in Africa?
No. Africa carries the greatest global burden, but malaria transmission also occurs across several other tropical and subtropical regions.
The World Health Organization estimated that the African Region accounted for approximately 95% of global malaria cases and deaths in 2024. That concentration can create the false impression that malaria is exclusively an African disease.
Travellers may also encounter malaria risk in the following regions:
| Region | Examples of where risk may occur | Important consideration |
| Sub-Saharan Africa | West, Central, East and parts of Southern Africa | Many areas have significant year-round risk |
| South Asia | Parts of India, Pakistan and neighbouring areas | Risk may vary greatly by state, district, season and itinerary |
| Southeast Asia | Forested or border regions in several countries | Some popular cities and resorts may have little or no risk while remote areas have risk |
| Central and South America | Parts of the Amazon Basin and rural tropical areas | Risk may be highly localised |
| Caribbean | Haiti and parts of the Dominican Republic | Advice depends on current local transmission |
| Middle East | Limited areas in or near countries with active transmission | Country recommendations can change |
| Pacific and Oceania | Papua New Guinea, Solomon Islands and some neighbouring areas | Risk may be substantial outside protected accommodation |
This table is an overview, not a country-specific recommendation. Always check current guidance for the precise places on your itinerary.
Why Does Malaria Risk Vary Within the Same Country?
Malaria risk varies because mosquito populations, parasite transmission, climate, altitude, healthcare access and prevention programmes are different from one area to another.
A traveller staying in a capital city may receive different advice from someone trekking through forests or staying in a rural village within the same country.
Important risk factors include:
Location
Rural, forested and agricultural areas often have more mosquito exposure than heavily developed urban centres. However, malaria can occur in certain towns and cities, so urban travel should not automatically be considered risk-free.
Season
Mosquito breeding frequently increases during and after rainy seasons. Some destinations have year-round transmission, while others have more seasonal risk.
Altitude
Transmission is generally less likely at higher altitudes because cooler temperatures can interrupt parasite development inside mosquitoes. The altitude at which risk becomes low differs between countries.
Length of stay
The longer you remain in a malaria-risk area, the greater your cumulative opportunity for exposure.
Accommodation
Air-conditioned or well-screened accommodation usually reduces mosquito exposure. Open accommodation, local homes, camps, hostels and rooms without window screens may increase risk.
Activities
Night-time outdoor work, camping, trekking, wildlife tours, farming, humanitarian work and forest visits can increase exposure.
Access to medical care
Remote travellers may have difficulty obtaining rapid malaria testing and treatment. This can affect the preventive plan recommended before departure.
How Is Malaria Transmitted?
Malaria is usually transmitted when an infected Anopheles mosquito bites a person and introduces malaria parasites into the bloodstream.
Anopheles mosquitoes can be active from dusk through the night, although activity patterns differ by mosquito species and location. Exposure may happen indoors or outdoors.
Malaria is not normally spread through everyday contact such as:
- Touching another person
- Sharing food
- Coughing or sneezing
- Using the same bathroom
- Swimming in the same water
Rare transmission routes can include infected blood, shared needles, needlestick injuries and transmission from a pregnant woman to her baby.
Who Is Most at Risk of Severe Malaria?
Any traveller can develop malaria, but some people have a greater chance of severe illness or complications.
Higher-risk groups include:
- Pregnant travellers
- Babies and young children
- Older travellers
- People with reduced immunity
- People without a functioning spleen
- Travellers with complex long-term health conditions
- People staying for extended periods
- Travellers visiting friends and relatives
- People travelling to remote areas with limited healthcare
- Travellers who do not complete their antimalarial course
Pregnant women are generally advised to avoid travel to malaria-risk areas where possible because malaria can be more severe during pregnancy and can affect both the mother and baby.
People without a functioning spleen require specialist advice. Travel to malaria-risk areas may be discouraged, depending on the itinerary and individual circumstances.
Are People Visiting Friends and Relatives Still at Risk?
Yes. People who were born or previously lived in malaria-endemic countries can still become infected after moving to the UK.
Partial immunity developed through repeated childhood exposure reduces over time once a person is no longer regularly exposed. It should never be assumed that someone remains protected because they grew up in a malaria-risk country.
Visiting-friends-and-relatives travellers may also:
- Stay longer than typical tourists
- Live in local homes without air conditioning or window screens
- Spend more time in residential or rural areas
- Travel during school holidays or rainy seasons
- Believe familiar destinations are safer than they are
- Be less likely to seek pre-travel advice
Every family member, including UK-born children, should receive an individual malaria risk assessment.
What Are the Symptoms of Malaria?
Common malaria symptoms include fever, chills, sweating, headache, muscle pain, tiredness, nausea and vomiting.
Malaria can initially resemble influenza, gastroenteritis or another routine viral illness.
Possible symptoms include:
- High temperature
- Feeling hot, cold or shivery
- Sweating
- Headache
- Muscle and joint pain
- Severe tiredness
- Nausea or vomiting
- Abdominal discomfort
- Diarrhoea
- Cough or breathing difficulties
- Confusion
- Loss of appetite
- Yellowing of the eyes or skin
- Dark or blood-stained urine
Severe malaria may cause breathing problems, seizures, impaired consciousness, severe anaemia, kidney problems, shock or abnormal bleeding.
How Soon Can Malaria Symptoms Appear?
Symptoms commonly begin within the first few weeks after infection, but some forms of malaria can appear months or, rarely, years later.
Many people develop symptoms approximately 7 to 18 days after being bitten. However, the timing depends on the malaria species, any antimalarial medication taken and the traveller’s previous exposure.
Plasmodium vivax and Plasmodium ovale can remain dormant in the liver and cause a later episode.
Tell a healthcare professional about your travel history whenever you become unwell after visiting a malaria-risk area, even if the journey no longer feels recent.
When Should You Seek Medical Help?
Seek urgent medical advice if you develop fever or malaria-like symptoms during travel or within 12 months of returning from a malaria-risk country.
Do not wait until you return to the UK if symptoms develop abroad.
When seeking care:
- State clearly that you have travelled to a malaria-risk area.
- Provide the countries, regions and dates of travel.
- Mention any stopovers, rural visits or overnight stays.
- Explain whether you took antimalarial medicine.
- Ask whether malaria testing is required.
Contact NHS 111 for urgent guidance if you develop possible malaria symptoms after returning to the UK. Call 999 or attend emergency care if you are seriously unwell, confused, short of breath, having seizures or losing consciousness.
A previous negative malaria test may occasionally need to be repeated if symptoms continue and clinical suspicion remains.
How Can Travellers Prevent Malaria?
The most effective strategy combines awareness, mosquito-bite prevention, appropriate antimalarial medicine and prompt diagnosis.
UK malaria guidance summarises this as the ABCD of malaria prevention:
A — Awareness of Risk
Know whether malaria occurs at your destination and understand that risk may vary between regions, seasons and activities.
B — Bite Prevention
Reduce the chance of being bitten by using effective insect repellent, suitable clothing, screened accommodation and insecticide-treated mosquito nets.
C — Chemoprophylaxis
Take the antimalarial medicine recommended for your destination and personal health circumstances.
D — Diagnose Promptly
Seek urgent medical assessment if you develop fever or other possible malaria symptoms during or after travel.
No single measure provides complete protection. Travellers should use all measures recommended for their individual journey.
How Can You Prevent Mosquito Bites?
Use repellent, protective clothing and suitable sleeping arrangements consistently throughout your trip.
Recommended precautions include:
- Apply an effective mosquito repellent to exposed skin.
- A 50% DEET-based repellent is commonly recommended for travellers when suitable.
- Follow the product’s instructions and reapply it when required.
- Apply sunscreen first and repellent afterwards.
- Wear loose, long-sleeved tops, long trousers and socks.
- Use air-conditioned or well-screened accommodation where possible.
- Keep windows and doors closed when screens are unavailable.
- Sleep under an insecticide-treated mosquito net when the room is not adequately screened.
- Check nets for holes and tuck them securely beneath the mattress.
- Continue bite precautions even when taking antimalarial tablets.
Babies, children, pregnant travellers and people with skin conditions should receive advice on selecting and using repellents correctly.
Which Antimalarial Tablets May Be Recommended?
The appropriate antimalarial depends on the destination, resistance patterns, trip length, age, medical history, pregnancy status and other medicines being taken.
Common options for UK travellers include atovaquone/proguanil, doxycycline and mefloquine. Chloroquine is appropriate only for a limited number of destinations because resistance is widespread.
| Medicine | Typical schedule | Potential advantages | Important considerations |
| Atovaquone/proguanil | Daily; usually started 1–2 days before entering the risk area and continued for 7 days after leaving | Short post-travel course; often well tolerated | Not appropriate for everyone, including some people with significant kidney impairment |
| Doxycycline | Daily; usually started 1–2 days before and continued for 4 weeks after leaving | Useful for many destinations; may suit last-minute travellers | Can cause sun sensitivity and digestive or throat irritation; not suitable for children under 12 and generally avoided during pregnancy |
| Mefloquine | Weekly; usually started 2–3 weeks before and continued for 4 weeks after leaving | Weekly dosing may suit longer trips | Requires careful screening and is unsuitable for people with certain psychiatric conditions, seizures or other contraindications |
| Chloroquine | Weekly; usually started before travel and continued for 4 weeks afterwards | Can be appropriate for limited chloroquine-sensitive areas | Not effective against resistant malaria in many destinations |
This comparison is general information only. It must not be used to choose or change malaria medication without a professional risk assessment.
Do Antimalarial Tablets Guarantee Protection?
No. Antimalarial medication substantially reduces risk when correctly selected and taken, but no medicine provides complete protection.
Protection can be reduced by:
- Missing doses
- Starting too late
- Stopping immediately after leaving the risk area
- Vomiting or severe diarrhoea
- Interactions with other medicines
- Using an unsuitable medicine for the destination
- Taking counterfeit or poor-quality tablets
- Incorrect dosing in children
- Failing to use mosquito-bite precautions
Even travellers who took every dose correctly must seek urgent medical advice if symptoms develop.
When Should You Arrange a Malaria Consultation?
Arrange travel health advice ideally four to six weeks before departure, although a last-minute appointment can still be valuable.
Early advice is particularly important when:
- Your itinerary includes several countries
- You are pregnant or planning pregnancy
- You are travelling with a baby or child
- You have a long-term health condition
- You take regular medication
- You have previously experienced antimalarial side effects
- You are travelling for several weeks or months
- You are visiting remote areas
- You are going on a cruise with multiple ports
- You are travelling for work, volunteering or humanitarian support
Some antimalarials can be started shortly before departure, while others should be started earlier to assess tolerability.
How Much Do Malaria Tablets Cost?
The cost depends on the medicine, trip duration, required quantity, traveller’s weight and whether a consultation fee applies.
A longer journey normally requires more tablets. Children may need paediatric formulations or weight-based dosing.
Before purchasing, ask whether the quoted amount covers:
- The pre-travel period
- Every day or week spent in the risk area
- The full post-travel course
- A professional risk assessment
- Any follow-up advice
- Medication for each family member
Hemel Hempstead Travel Clinic can provide a personalised recommendation and confirm the applicable cost after reviewing your itinerary and medical information.
Malaria Tablets vs Mosquito-Bite Prevention: Which Is More Important?
Neither should replace the other. Travellers advised to use antimalarial medicine should normally combine it with rigorous bite prevention.
| Antimalarial medication | Mosquito-bite prevention |
| Acts against malaria parasites after exposure | Reduces the chance of an infected mosquito biting |
| Must match local resistance patterns | Helps protect against malaria and other mosquito-borne infections |
| Requires correct dosing and completion | Requires consistent daily and night-time precautions |
| Does not provide complete protection | Cannot prevent every bite |
| May cause side effects or interactions | Repellents must be selected and used correctly |
The strongest approach is layered protection rather than relying on a single measure.
What Common Mistakes Increase Malaria Risk?
Most avoidable failures involve underestimating risk, missing medication or seeking medical help too late.
Common mistakes include:
- Assuming malaria occurs only in Africa.
- Checking only the country rather than the exact itinerary.
- Believing a city, beach resort or luxury hotel must be risk-free.
- Relying entirely on antimalarial tablets.
- Skipping doses after drinking alcohol or changing time zones.
- Ending the course as soon as the flight home lands.
- Using medication left over from another journey.
- Buying tablets from an unverified overseas seller.
- Assuming previous residence in a malaria country provides lifelong immunity.
- Ignoring fever because every prescribed tablet was taken.
- Forgetting to mention recent travel to a doctor.
- Waiting for a regular pattern of fever before seeking help.
What Are the Most Common Misconceptions About Malaria?
“Malaria only occurs in Africa.”
False. Africa has the highest burden, but transmission also occurs in parts of Asia, Latin America, the Caribbean, the Middle East and the Pacific.
“I grew up there, so I am immune.”
False. Any partial protection gained from repeated exposure can decline after living away from the area.
“I am staying in a city, so I do not need advice.”
Not always true. Risk varies between cities and can change over time. Your complete itinerary must be assessed.
“Malaria tablets mean mosquito repellent is unnecessary.”
False. No antimalarial provides complete protection, and mosquito-bite precautions also help reduce exposure to dengue, chikungunya and other infections.
“Malaria always produces a repeating fever.”
False. Early symptoms may be vague, irregular and similar to common viral illnesses.
“If I feel well when I return, I cannot have malaria.”
False. Symptoms can appear weeks or months later, and some species can cause much later illness.
“There is a routine travel vaccine that replaces malaria tablets.”
For most UK travellers, malaria prevention relies on risk assessment, bite prevention and antimalarial medicine where recommended. Malaria vaccines used in endemic-country public health programmes are not a substitute for personalised traveller precautions.
How Does Malaria Risk in Africa Compare With Risk Elsewhere?
Africa generally has the greatest intensity of malaria transmission, but non-African risk should not be dismissed.
| Factor | Many sub-Saharan African destinations | Destinations outside Africa |
| Overall burden | Very high in many countries | Lower overall but significant in particular regions |
| Main parasite concern | Plasmodium falciparum is common | Plasmodium vivax is important in many areas; falciparum and knowlesi may also occur |
| Geographic pattern | Risk may be widespread | Risk is often more localised |
| Urban risk | Can occur in some cities | Often concentrated in rural, forest or border areas, depending on the country |
| Seasonal variation | Year-round in many locations, with seasonal increases | May be strongly linked to rainfall, altitude or specific regions |
| Traveller assumption | Risk is often recognised | Risk may be overlooked because the destination is not in Africa |
The consequences of malaria can be serious regardless of where the infection was acquired.

Frequently Asked Questions
Malaria is not normally acquired through routine mosquito transmission in the UK. UK cases are predominantly diagnosed in people who became infected while abroad.
Ideally, arrange advice four to six weeks before departure. A last-minute consultation is still worthwhile because some options can be started shortly before travel.
Yes, but the appropriate medicine and dose depend on the child’s age, weight, destination and health. Children should receive an individual assessment.
Some medicines may be considered after an individual risk assessment, but pregnancy increases the danger of severe malaria. Pregnant travellers are generally advised to avoid malaria-risk areas where possible.
Alcohol does not affect every antimalarial in the same way, but it may worsen certain side effects or make missed doses more likely. Discuss alcohol use with the clinician recommending your medicine
Take professional advice or follow the medicine’s patient information leaflet. Do not double a dose unless specifically instructed. Continue mosquito-bite precautions carefully.
Yes. Depending on the medicine, the post-travel course may last seven days or four weeks. Stopping early can leave you unprotected.
Not without a new assessment. Recommendations may differ by destination, resistance patterns, trip length, and changes in your health or medication.
Bracelets should not replace proven protection such as effective skin repellent, protective clothing, screened rooms and insecticide-treated mosquito nets.
Yes. Malaria must still be considered. Tell the healthcare professional exactly where and when you travelled.
Possibly. Even a brief visit can involve exposure. Recommendations depend on the location, season, accommodation, and activities rather than trip length alone.
Yes. A complete travel health consultation can review malaria prevention alongside vaccines, food and water safety, mosquito-borne diseases, and other destination-specific risks.
