Quick overview
Malaria is transmitted by Anopheles mosquitoes. The disease can be severe and fatal if untreated, so prevention is essential for travellers entering endemic zones.
Where malaria risk is present
In 2026 the highest risk remains in most of Sub‑Saharan Africa, especially West and Central African countries. In Asia, risk persists in parts of India, Bangladesh, Pakistan, and the forested regions of Myanmar, Thailand, Laos, Vietnam, and Indonesia. Oceania risk is limited to Papua New Guinea and some Solomon Islands. In the Americas, malaria occurs in rural areas of Brazil, Colombia, Peru, and parts of Central America (e.g., Honduras, Guatemala).
| Region | Typical risk level | Notes |
|---|---|---|
| Sub‑Saharan Africa | High | Most countries require prophylaxis |
| South‑East Asia (forest zones) | Moderate | Check local advisories |
| Oceania (PNG, Solomons) | Moderate | Seasonal spikes |
| Latin America (rural) | Low‑moderate | Limited to specific districts |

Prophylactic tablets and how to use them
Three main regimens are recommended by most health agencies:
• Atovaquone‑proguanil (Malarone) – taken daily with food, started 1–2 days before entry and continued for 7 days after leaving.
• Doxycycline – taken daily with a full glass of water, started 1–2 days before entry and continued for 7 days after leaving. Sun‑sensitivity is a common side‑effect.
• Mefloquine – taken weekly, started at least 2 weeks before travel to allow for tolerance testing, continued for 4 weeks after leaving. Neuro‑psychiatric side‑effects may limit use.
Do
- Choose a tablet based on personal health, allergy history, and length of stay.
- If you have a history of depression or seizures, avoid mefloquine.
Watch out
- Do not rely on tablets alone; use mosquito bite prevention (nets, repellent).
Cost, availability and how to obtain tablets
In 2026 most travel clinics in the US, UK, Canada, Australia and New Zealand stock the three main tablets. Prices vary:
• Atovaquone‑proguanil: US$30‑$70 for a 2‑week course.
• Doxycycline: US$15‑$40 for a 2‑week course.
• Mefloquine: US$50‑$120 for a 4‑week course.
Do
- Buy from a reputable pharmacy or travel clinic; avoid online sources without verification.
Watch out
- Check for drug interactions with any regular medication.
Exceptions, special cases and alternatives
Pregnant travellers should avoid mefloquine and doxycycline; atovaquone‑proguanil may be used after consulting a doctor. Children under 5 kg generally cannot take atovaquone‑proguanil; doxycycline is contraindicated under 8 years. In areas of very low risk, some agencies allow travellers to forgo prophylaxis if strict bite‑prevention measures are used.
Do
- Carry a copy of your prescription and a letter from your doctor when traveling with tablets.
Watch out
- Skipping prophylaxis in a high‑risk zone greatly increases the chance of infection.

Questions people ask
What is the short answer for malaria prevention?
Take a daily prophylactic tablet (atovaquone‑proguanil or doxycycline) for any itinerary that includes malaria‑risk zones, start before travel and continue after leaving.
Who does malaria prophylaxis apply to?
All travellers entering areas with documented malaria transmission, especially those staying longer than a few days, pregnant women, children, and immunocompromised individuals should follow the guidance.
How much does it cost and how long does it take to get the tablets?
A 2‑week course costs roughly US$30‑$70 for atovaquone‑proguanil, US$15‑$40 for doxycycline, or US$50‑$120 for mefloquine. Obtaining them usually requires a short appointment at a travel clinic (15‑30 min).
Can I skip tablets if I use mosquito nets and repellent?
In very low‑risk areas some agencies allow it, but in high‑risk zones tablets are strongly recommended even with bite‑prevention measures.
What should I do if I develop fever after returning from a risk area?
Seek medical attention promptly; inform the clinician of recent travel and possible malaria exposure. Early diagnosis and treatment are critical.
