savo East National Park, one of Kenya’s largest and most famous safari destinations, is home to stunning landscapes, incredible wildlife, and diverse ecosystems. However, like many other regions in Kenya, Tsavo East falls within a malaria-prone area. If you’re planning a safari, it’s essential to understand the malaria risk, how to prevent infection, and what precautions to take to ensure a safe and enjoyable trip.
This guide provides comprehensive information on malaria in Tsavo East, including risk levels, best prevention methods, and travel safety tips.
1. Is Malaria a Concern in Tsavo East National Park?
Yes, malaria is present in Tsavo East, as it is in many low-altitude and tropical regions of Kenya. However, the risk varies depending on the season, altitude, and your accommodation choices.
Malaria Risk Factors in Tsavo East
✔ Climate: Tsavo East has a warm climate with seasonal rainfall, which can create breeding grounds for mosquitoes.
✔ Low Elevation: The park lies at an average altitude of 200 – 1,000 meters (650 – 3,280 feet), where malaria transmission is higher than in high-altitude regions like Nairobi.
✔ Water Sources: Areas around River Galana, waterholes, and swamps may have more mosquitoes, especially during the wet season.
The good news is that most safari camps and lodges take malaria prevention seriously, implementing mosquito control measures such as insect-proof tents, mosquito nets, and spraying treatments.
2. Malaria Transmission and Symptoms
How Malaria is Spread
Malaria is caused by Plasmodium parasites, transmitted through the bite of an infected female Anopheles mosquito. The mosquitoes are most active during the night (dusk to dawn).
Common Malaria Symptoms
If infected, malaria symptoms usually appear 7–14 days after being bitten and can include:
- High fever and chills
- Headache and muscle aches
- Fatigue and weakness
- Sweating and nausea
- Vomiting or diarrhea
Malaria can be severe and life-threatening if untreated, which is why prevention is key when visiting malaria-prone areas like Tsavo East.
3. Best Ways to Prevent Malaria in Tsavo East
✅ 1. Take Antimalarial Medication
One of the most effective ways to prevent malaria is by taking antimalarial tablets (prophylaxis) before, during, and after your trip. Common options include:
| Medication | Dosage & Notes |
|---|---|
| Malarone (Atovaquone-Proguanil) | Taken daily, start 1-2 days before travel, continue during your stay, and for 7 days after leaving. Well-tolerated with few side effects. |
| Doxycycline | Taken daily, start 1-2 days before travel, continue during the trip, and for 4 weeks after leaving. May cause sun sensitivity. |
| Mefloquine (Lariam) | Taken weekly, start 2 weeks before travel, continue during your stay, and for 4 weeks after leaving. Not recommended for those with a history of anxiety or depression. |
💡 Tip: Consult a travel doctor at least 4-6 weeks before your trip to discuss the best antimalarial option for you.
✅ 2. Use Mosquito Repellent
Applying mosquito repellent on exposed skin significantly reduces bites. Look for repellents containing:
✔ DEET (30-50%) – The most effective repellent against mosquitoes.
✔ Picaridin (20%) – A good alternative to DEET with fewer skin irritations.
✔ Oil of Lemon Eucalyptus (OLE) – A natural option, though less effective than DEET.
💡 Tip: Reapply repellent every 4-6 hours, especially in the evening.
✅ 3. Sleep Under a Mosquito Net
Most safari lodges and camps in Tsavo East provide insecticide-treated mosquito nets over the beds. Ensure you:
✔ Use the net properly tucked under the mattress.
✔ Avoid touching the net while sleeping to prevent mosquitoes from biting through.
✔ Check for any holes or tears before bedtime.
✅ 4. Wear Protective Clothing
To minimize mosquito bites:
✔ Wear long-sleeved shirts and pants, especially at night.
✔ Choose light-colored clothing, as mosquitoes are attracted to dark colors.
✔ Treat clothes with permethrin, an insect-repelling chemical.
✅ 5. Choose Your Accommodation Wisely
✔ Stay at lodges or tented camps with mosquito protection measures, such as screened windows, ceiling fans, and mosquito coils.
✔ Avoid sleeping outdoors without proper mosquito protection.
✅ 6. Avoid Peak Mosquito Activity Hours
Mosquitoes that transmit malaria are most active from dusk to dawn. Reduce your risk by:
✔ Staying indoors during peak hours if possible.
✔ Using air conditioning or fans to deter mosquitoes.
✔ Sitting near a campfire or citronella candles, which naturally repel mosquitoes.
4. When is Malaria Risk Highest in Tsavo East?
The risk of malaria fluctuates throughout the year, depending on rainfall patterns.
✔ High Risk: During the rainy seasons (March-May & November-December) when standing water increases mosquito breeding.
✔ Lower Risk: During the dry season (June-October & January-February) when mosquitoes are fewer due to limited water sources.
💡 Tip: If you’re particularly concerned about malaria, consider visiting during the dry season, when the risk is lower.
5. What to Do if You Develop Malaria Symptoms?
If you experience fever, chills, or flu-like symptoms after visiting Tsavo East:
✔ Seek medical help immediately – Malaria progresses quickly if untreated.
✔ Request a malaria test at a local hospital or clinic.
✔ Start treatment promptly – Malaria can be treated with artemisinin-based combination therapy (ACTs).
💡 Tip: If symptoms appear after returning home, inform your doctor that you traveled to a malaria-endemic area.
6. Myths About Malaria in Tsavo East
❌ Myth: Only locals get malaria – Reality: Travelers are also at risk without proper precautions.
❌ Myth: Malaria vaccines exist – Reality: There is no widely available malaria vaccine for travelers.
❌ Myth: Wearing bug spray alone is enough – Reality: Mosquito nets, protective clothing, and antimalarial meds provide better protection.
7. Final Tips for a Safe Safari in Tsavo East

FAQs
1. Are malaria cases common among safari tourists in Tsavo East?
💡 Answer: Malaria cases among safari tourists in Tsavo East are relatively rare, especially for those who take proper precautions such as taking antimalarial medication, using insect repellent, and sleeping under mosquito nets. Most safari accommodations also implement mosquito control measures, reducing the likelihood of infection.
2. Do mosquitoes bite during the daytime in Tsavo East?
💡 Answer: The mosquito species that transmit malaria (Anopheles mosquitoes) are most active at night (dusk to dawn). However, other mosquito species can bite during the day, though they are not malaria carriers. To avoid all mosquito bites, it’s still advisable to wear long clothing and use repellent throughout the day.
3. Can I rely on mosquito repellent alone to protect against malaria?
💡 Answer: No. While mosquito repellent is an important defense, it should be used in combination with antimalarial medication, bed nets, and protective clothing. DEET-based repellents (30-50%) are the most effective, but they alone cannot provide 100% protection.
4. What should I do if I forget to take my antimalarial pills before my trip?
💡 Answer: If you forget to start your antimalarial medication before traveling, begin taking it as soon as you remember. Some antimalarials, like Malarone (Atovaquone-Proguanil), can still be started 1-2 days before entering a malaria area. However, other medications like Mefloquine require 2 weeks of pre-travel use.
If you have already arrived in Tsavo East and haven’t taken any preventive medication, focus on mosquito bite prevention and seek medical advice on whether post-exposure treatment may be necessary.
5. Do children and pregnant women face higher malaria risks in Tsavo East?
💡 Answer: Yes. Malaria can be more severe in children, pregnant women, and elderly travelers because of their weaker immune systems. Pregnant women, in particular, face higher risks of complications, and many doctors recommend avoiding malaria-prone areas if possible.
If travel is unavoidable, strict malaria prevention measures should be followed, and certain antimalarial medications may not be suitable during pregnancy. Always consult a doctor before traveling.
6. Do malaria mosquitoes breed inside safari lodges and tents?
💡 Answer: Malaria mosquitoes typically breed in stagnant water sources and prefer outdoor areas near rivers, swamps, and puddles. Most safari lodges in Tsavo East regularly spray insecticides, install mosquito screens, and provide treated mosquito nets, reducing the chance of mosquitoes breeding indoors.
To stay extra safe:
✔ Keep your tent or lodge windows closed at night.
✔ Use a mosquito coil or spray repellent before sleeping.
✔ Avoid leaving lights on inside your tent, as they can attract insects.
7. Can I get vaccinated against malaria before visiting Tsavo East?
💡 Answer: No, there is no widely available malaria vaccine for travelers. The malaria vaccine (RTS,S) is currently only being rolled out for young children in high-risk African regions and is not part of routine travel vaccinations.
To protect yourself, take antimalarial medication, use insect repellent, and follow mosquito prevention strategies.
8. How does malaria in Tsavo East compare to malaria in other parts of Kenya?
💡 Answer: Malaria risk in Tsavo East is moderate to high, similar to other low-altitude, warm-climate regions of Kenya such as the Masai Mara, Amboseli, and the coastal areas like Mombasa and Diani.
However, malaria risk is much lower in high-altitude cities like Nairobi (1,795m/5,889ft) and Mount Kenya, where mosquitoes struggle to survive due to the cool climate.
If you’re traveling between malaria-free areas (like Nairobi) and Tsavo East, you must start taking malaria precautions before entering the park.
9. Are malaria mosquitoes active all year round in Tsavo East?
💡 Answer: Yes, but the risk is highest during the rainy seasons (March-May & November-December) because stagnant water accumulates, creating ideal breeding conditions for mosquitoes.
The dry season (June-October & January-February) has fewer mosquitoes, making it a better time to visit if you’re concerned about malaria.
10. Can I stop taking my antimalarial medication once I leave Tsavo East?
💡 Answer: No. Most malaria medications require you to continue taking them after leaving a malaria-prone area to ensure any undetected parasites in your system are eliminated.
✔ Malarone (Atovaquone-Proguanil) – Take for 7 days after leaving.
✔ Doxycycline – Take for 4 weeks after leaving.
✔ Mefloquine (Lariam) – Take for 4 weeks after leaving.
Stopping your medication too early puts you at risk of developing malaria even after you’ve returned home.
11. Is malaria treatment available inside Tsavo East National Park?
💡 Answer: No, there are no major medical facilities inside Tsavo East. The nearest treatment centers are in Voi, Mombasa, and Nairobi.
If you develop malaria symptoms while on safari:
✔ Notify your safari guide immediately.
✔ Travel to the nearest hospital or clinic for a malaria test.
✔ If positive, take artemisinin-based combination therapy (ACTs), the most effective treatment.
💡 Tip: Travel insurance covering emergency evacuation is highly recommended in case medical care is needed outside the park.
12. Are herbal remedies or homeopathic treatments effective against malaria?
💡 Answer: No. Herbal or homeopathic remedies do not provide reliable protection or treatment for malaria. The only proven ways to prevent malaria are:
✔ Taking approved antimalarial medication.
✔ Using mosquito repellents with DEET or Picaridin.
✔ Sleeping under treated mosquito nets.
If you contract malaria, seek immediate medical treatment rather than relying on alternative therapies.
13. Can I still donate blood after visiting Tsavo East?
💡 Answer: Most blood donation centers require travelers to wait 6-12 months before donating blood if they have visited a malaria-endemic area like Tsavo East.
This is a precaution to ensure you are malaria-free before donating. If you experience symptoms after your trip, inform your doctor before attempting to donate blood.
14. Are malaria risks the same for short and long visits to Tsavo East?
💡 Answer: Even short-term visitors are at risk of malaria. It only takes one infected mosquito bite to contract the disease.
Whether you’re staying in Tsavo East for one night or a full week, taking malaria precautions is essential.
15. Should I still worry about malaria if I’ve visited Africa before without getting sick?
💡 Answer: Yes. Immunity to malaria does not develop in travelers, even if you’ve been to Africa multiple times without getting sick.
Each visit presents a new risk, so you should always take malaria precautions every time you visit Tsavo East or any other malaria-endemic area.
