Some of the most regularly asked questions we get from clients are about the malaria risks on African safaris. In this guide to malaria, we set out all the facts about this potentially deadly disease. From transmission to prevention to everything in between, we’ll make it plain and simple to understand malaria.
Without wanting to scare you, we want to be sure you know how serious malaria is, and why protecting yourself against it is vital. Know the facts. This will help you to be prepared and stay safe on African safaris.
Malaria is transmitted by the female Anopheles mosquito. The mosquito bites the human and injects the malaria parasite into the blood, from where it travels into the liver and multiplies and changes. The parasites then infect the red blood cells. It is at this point that the person will become symptomatic.
The parasite at this stage can be picked up again by a mosquito that bites the human. It undergoes another lifecycle in the mosquito’s stomach. From there the parasite travels to the mosquito’s salivary glands, and the whole process starts again.

As described above in the lifecycle section, malaria is transmitted by being bitten by the female Anopheles mosquito.
Malaria is not contagious, i.e. it can’t spread from person to person like a cold. It is also not sexually transmitted. And no, you cannot get malaria from drinking contaminated water or eating rotten fruit.
The only other (highly unusual) routes of transmission are from blood transfusions, organ transplants or needle-sharing with an infected person. It can also be passed from mother to child during pregnancy or delivery.
You could also potentially be infected by an imported mosquito. This is possible if one or more malaria-carrying mosquitoes are accidentally transported from their natural home. They could randomly infect people outside a traditional malaria-risk area. This could be possible if you stayed near a major transport route or transport hub.
The symptoms of malaria usually mimic those of flu (tiredness, sweats and chills, headache, painful muscles etc.), and generally include a fever. Nausea, vomiting and diarrhea may also occur. Symptoms usually begin 10 days to a month after infection but, depending on the strain, can present earlier, or as much as a year later.
If left untreated, symptoms can rapidly progress to mental confusion, seizure, kidney failure, coma and death.
Should you feel ill in any way during your stay in a malaria area, or after leaving the area, consult your medical practitioner immediately and be sure to tell them that you’ve been to a malaria-endemic area.
Malaria can only be reliably diagnosed – and which strain it is – on examination of a blood sample under a microscope. The test must be performed without delay. If, however, you are in the middle of nowhere, with no access to a lab, and you present with malaria symptoms, backup treatment should be started while you get to the closest medical facility. Do not delay.
Malaria is treatable, and it is vital to treat it immediately.
While it is possible (and wise) to take standby treatment, such as Coartem®, as part of your medical kit this should not, under any circumstances, be considered as an alternative to seeking medical care. It is indicated for the treatment of uncomplicated malaria and may well treat you, BUT if you have severe malaria it may progress very quickly and require other medicines, such as quinine.
We can’t state it too many times: untreated or improperly treated malaria can be fatal, and it can get severe, quickly.
If you suspect you have malaria, seek medical help immediately.
A number of steps can be taken to keep yourself safe from malaria while on safari in Africa. While none are 100% effective at preventing malaria, combining them all will significantly reduce your risk.
The most effective way of avoiding malaria is to avoid being bitten by mosquitoes. While this sounds impossible when you’re coming to Africa to spend your time outdoors, there are a large number of things you can do to keep the little critters at bay:
See the common misconceptions about malaria, produced by the National Institute for Communicable Diseases.
There are three main options when it comes to anti-malarial medicines. Prophylaxis should be used in conjunction with the non-drug measures mentioned above. The choice of which medicine should be used must be decided on a person-by-person basis in consultation with your medical practitioner.
A number of factors will influence the choice of medicine. These include underlying medical conditions, other medication being taken and tolerance of the chosen prophylactic medicine.
Should you be travelling with children, be pregnant (or wanting to fall pregnant), breastfeeding or have any underlying medical conditions or concomitant medications, it is even more vital to discuss prophylactic options with your doctor or a travel clinic well in advance of your safari.
We advise starting your malaria prophylaxis well in advance, to ensure that you tolerate it. Should you experience side effects, consult your medical practitioner.
Some tradenames: Efracea®; Periostat®; Vibramycin-D®; Vibrox®; Doryx®; Oracea®; Doxymal®
Taken daily (100 mg), starting at least 48 hours before entering the malaria area, daily while in the area, and daily for four weeks after leaving the area.
The most commonly experienced side effects are gastrointestinal (nausea, vomiting, diarrhea). Taking the medication with the biggest meal of the day helps to minimize this. Doxycycline may also cause oesophagitis (burning throat), but swallowing the pill with a large glass of water and staying upright for a while after taking will prevent it.
Doxycycline may interfere with the efficacy of the oral contraceptive pill. Avoid milk/dairy products for a couple of hours as it may affect absorption.
Some tradenames: Lariam®; Mefliam®
Taken weekly (250 mg), starting at least 10 days before entering the malaria area, weekly (on the same day of the week) while in the area, and weekly for four weeks after leaving the area.
Mefloquine is contraindicated in people with a history of epilepsy, cardiac problems or psychiatric problems. The drug may cause psychiatric side effects ranging from mild anxiety and nightmares to, in the most severe cases, psychosis. Report any such side effects to your doctor, as you may need to change to an alternative malaria prophylaxis medication.
Some tradenames: Malarone®; Malanil®; Numal®
Taken daily (250 mg/100 mg), starting 48 hours before entering the malaria area, daily while in the area, and daily for one week after leaving the area.
The most common side effects are headache and nausea, vomiting and/or diarrhea. Again, taking the medicine with a big meal can minimize this.
The highest transmission of malaria occurs in Sub-Saharan Africa – the countries with warm, wet climates.
All of the countries visited on safaris offered by ABS are malaria-endemic (see below for WHO country-by-country classification). It is important, however, to note that in many of the countries (especially South Africa, Namibia and Botswana), only certain parts of the country are malarial, while other parts are completely malaria-free.
Transmission of malaria doesn’t occur in some areas:
Below we include the malaria areas by country, as described by the World Health Organisation's (WHO) International Travel and Health. Please note that in some countries only certain parts are malarial. If you are unsure about where your safari goes or if it includes visits to malaria areas, contact our African Budget Safari consultant and we will happily help you.
