Understanding Malaria 

Malaria is a parasitic infection spread by mosquitoes. When an infected mosquito bites a person, it transmits the Plasmodium parasite into their bloodstream. There are five species of Plasmodium that can infect humans, with P. falciparum being the most dangerous. 

Malaria is prevalent in many tropical and subtropical regions, including large areas of Africa and Asia, Central and South America, Dominican Republic and Haiti, parts of the Middle East, and some Pacific islands. 

It’s essential to check the malaria risk for your specific destination before travelling. The risk of contracting malaria can vary depending on factors such as the time of year, altitude, and specific location within a country. 

Recognising Malaria Symptoms 

Even with proper prophylaxis, it’s crucial to be aware of malaria symptoms. These symptoms usually appear between 6 to 30 days after you’ve been bitten by an infected mosquito – but sometimes it can take up to a year for symptoms to start. 

Malaria can be hard to spot, but the common symptoms include: 

  • A high temperature, sweats and chills 
  • Headaches and feeling confused 
  • Feeling very tired and sleepy 
  • Feeling and being sick, tummy pain and diarrhoea 
  • Loss of appetite 
  • Muscle pains 
  • Yellow skin or whites of the eyes 
  • A sore throat, cough and difficulty breathing 

These symptoms can be similar to flu symptoms, which is why it’s important to inform your doctor about your travel history if you experience these symptoms during or after travel to a malaria-endemic area. You should seek medical attention immediately if you suspect malaria, as early diagnosis and treatment are crucial for preventing severe complications. 

The Importance Of Malaria Prophylaxis 

Malaria prophylaxis refers to the preventive measures taken to reduce the risk of contracting malaria. These measures include taking antimalarial medications, mosquito bite prevention, and awareness of malaria symptoms. 

Taking precautions against malaria is crucial for several important reasons. Firstly, malaria can be fatal if not treated promptly. Additionally, some strains of malaria are becoming resistant to certain medications, making prevention even more critical. It’s also important to note that malaria symptoms can appear weeks or even months after exposure, which can complicate timely treatment. Therefore, prevention is more effective and less risky than treating an active infection. 

Proper malaria prophylaxis can significantly reduce your risk of contracting the disease, ensuring a safer and more enjoyable trip to malaria-endemic regions. It’s an essential part of travel health that should not be overlooked. 

Antimalarial Medications 

There are several antimalarial medications available for prophylaxis. The choice of medication depends on factors such as the destination, duration of stay, medical history, and potential side effects. 

Atovaquone/Proguanil (Malarone) 

Atovaquone/Proguanil, commonly known as Malarone, is a popular antimalarial medication due to its effectiveness and ease of use. It is particularly effective against most malaria strains, making it a reliable option for travellers heading to malaria-endemic regions. One of the key advantages of Malarone is that it tends to cause fewer side effects compared to other antimalarial drugs. Additionally, the course is relatively short, requiring you to start the medication just 1-2 days before travel and continue it for only 7 days after returning. 

However, Malarone does have some drawbacks. The medication must be taken daily, which can be less convenient for some. Despite this, Malarone remains suitable for most travellers, particularly in areas with chloroquine-resistant malaria. 

Doxycycline 

Doxycycline is an antibiotic that also serves as an effective antimalarial. It is widely used due to its versatility, making it a good option for travellers visiting various malaria-endemic areas. Besides its antimalarial properties, Doxycycline also provides protection against some other travel-related illnesses, offering additional benefits for those concerned about a range of potential health risks while abroad. 

The main downsides of Doxycycline include the requirement for daily dosing, which can be inconvenient for long-term travellers. It can also increase sensitivity to the sun, posing a risk of sunburn, and may cause gastrointestinal side effects in some individuals. 

Mefloquine (Lariam) 

Mefloquine is a long-acting antimalarial medication favoured by travellers who prefer the convenience of weekly dosing. Its efficacy in most malaria-endemic areas makes it a valuable option for those planning extended stays in regions where malaria is prevalent. The weekly dosing schedule is a significant advantage for those who find daily medication regimens cumbersome. 

However, Mefloquine is associated with a higher risk of neuropsychiatric side effects, such as anxiety, depression, and vivid dreams. Due to these potential side effects, it is not suitable for individuals with certain mental health conditions or seizure disorders. 

Chloroquine 

Chloroquine is one of the oldest and most well-known antimalarial drugs. It has been widely used for decades and is generally well-tolerated by most individuals. One of its main advantages is the convenience of weekly dosing, which makes it easier to adhere to the medication schedule during travel. 

However, the effectiveness of Chloroquine has been severely limited due to the widespread resistance that has developed in many malaria-endemic regions 

It’s crucial to consult with your doctor or a travel clinic to determine the best antimalarial regimen for your specific situation and destination. 

Mosquito Bite Prevention

While antimalarial medications are essential, preventing mosquito bites is equally important. Here are some effective strategies: 

  • Use EPA-registered insect repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol, or 2-undecanone. 
  • Wear protective clothing such as long-sleeved shirts, long pants, and socks, especially during peak mosquito hours (dusk to dawn). 
  • Sleep under insecticide-treated bed nets, particularly in accommodations without adequate screening or air conditioning. 
  • Use indoor insect spray, mosquito coils, or plug-in insecticide vaporizers in your accommodation. 
  • Choose accommodations with air conditioning or proper window and door screens when possible. 
  • Treat clothing and gear with permethrin or purchase permethrin-treated items for extra protection. 

Remember, mosquitoes that transmit malaria typically bite between dusk and dawn, so extra precautions during these hours are crucial. 

Special Considerations 

Certain groups of travellers may need to take extra precautions or consider alternative prophylaxis strategies: 

  • Pregnant women: They are at higher risk of severe malaria and should, if possible, avoid travel to malaria-endemic areas. If travel is necessary, consult with a doctor for appropriate prophylaxis options. 
  • Children: They are particularly vulnerable to severe malaria. Ensure they take appropriate antimalarial medications and are protected from mosquito bites. Some medications may need to be adjusted based on the child’s weight. 
  • Long-term travellers and expatriates: People staying in malaria-endemic areas for extended periods may need to adjust their prophylaxis strategy. 
  • Individuals with pre-existing medical conditions: Certain health conditions may influence the choice of antimalarial medication. Always inform your healthcare provider about any pre-existing conditions. 

After Your Trip 

It’s important to remember that malaria prevention doesn’t end when you leave the endemic area. Here are important steps to take after your trip: 

  • Continue taking your antimalarial medication as prescribed after leaving the malaria-endemic area. The duration varies depending on the medication, but it’s typically 1-4 weeks. 
  • Monitor your health for up to a year after your return. If you experience any symptoms of malaria, even months after your trip, seek medical attention immediately and inform your healthcare provider about your travel history. 
  • If you’ve been taking long-term prophylaxis, consult with your healthcare provider about when and how to safely discontinue the medication. 
  • Consider getting a check-up if you’ve been in a high-risk area for an extended period, even if you don’t have symptoms. 
  • If you’re planning future trips to malaria-endemic areas, review your experience with your current prophylaxis and discuss any concerns with a healthcare provider.
