About Malaria

Malaria is a severe, mosquito-borne infectious disease prevalent mainly in tropical regions. The disease is caused by the Plasmodium parasite, transmitted to humans through the bites of infected female Anopheles mosquitoes. After transmission, the parasites migrate to the liver, where they mature and reproduce, eventually affecting red blood cells and causing symptoms. Malaria’s impact is substantial, with millions affected worldwide annually. The disease poses the highest threat in Sub-Saharan Africa, where the most lethal parasite species, Plasmodium falciparum, is prevalent. Despite being a grave health challenge, malaria is preventable and curable, with effective strategies and prescription treatments available.

Symptoms

The typical symptoms of malaria include:

● Fever and Sweating: Malaria often begins with a high fever, accompanied by sweating.
● Chills: Severe chills that may shake the whole body are common.
● Headache and Muscle Aches: These symptoms are similar to those experienced with the flu.
● Fatigue: A profound sense of tiredness is frequently reported.
● Chest Pain and Difficulty Breathing: As the infection progresses, respiratory symptoms can occur.
● Gastrointestinal Symptoms: This includes nausea, vomiting, diarrhoea, and abdominal pain.
● Jaundice: In more severe cases, yellowing of the skin and the whites of the eyes can appear.
● Cognitive Symptoms: Confusion and disorientation may also present in severe cases.
● Anaemia: Due to the destruction of red blood cells by the malaria parasite.

These symptoms generally appear 7 to 18 days after being bitten by an infected mosquito, but can sometimes take longer to manifest.

Diagnosis

Diagnosing malaria involves both clinical evaluation and laboratory tests. Doctors first assess the patient’s travel history to regions where malaria is common and check for symptoms like fever, chills, and flu-like illness. However, a definitive diagnosis requires laboratory confirmation.

The most common method is a blood smear microscopy, where a drop of blood is examined under a microscope to identify malaria parasites. Rapid diagnostic tests (RDTs) are also frequently used; these detect specific antigens produced by malaria parasites and provide quick results. In some cases, polymerase chain reaction (PCR) tests are used to detect the DNA of the malaria parasite, offering higher sensitivity and specificity but are less commonly employed due to their cost and processing time.

Early diagnosis is crucial to begin effective treatment and prevent severe complications. If malaria is suspected, seeking medical attention promptly for testing and starting the appropriate treatment is essential.

Treatments

Prescription medicines play a crucial role in both the prevention and treatment of malaria. They work by killing the malaria parasites that are transmitted through the bites of infected mosquitoes. Here are four commonly prescribed anti-malaria medications and how they help in managing the condition:

Doxycycline Capsules 100mg

How it helps: Doxycycline is an antibiotic that also acts as an effective anti-malaria tablet. It prevents the malaria parasite from multiplying in the blood, thus stopping the infection from developing.
Usage: It is taken daily, starting a couple of days before entering a malaria-endemic area and continued for a few weeks after leaving the area to ensure complete protection.
Benefits: Prevents contraction of malaria when travelling to tropical regions.

Atovaquone and Proguanil 250mg/100mg (Generic Malarone)

How it helps: This combination tablet interferes with the parasite’s ability to reproduce and spread within the body. Atovaquone disrupts the parasite’s mitochondrial function, while Proguanil inhibits dihydrofolate reductase, an enzyme crucial for DNA synthesis in the parasite.
Usage: Taken daily, starting 1-2 days before travel and continued for 7 days after leaving the endemic area.
Benefits: Effective in preventing and treating malaria, especially in regions with chloroquine-resistant strains.

Branded Malarone Tablets 250mg/100mg

How it helps: Similar to its generic counterpart, Branded Malarone offers a powerful combination of Atovaquone and Proguanil. This dual-action approach effectively prevents the malaria parasite from multiplying and spreading within the body.
Usage: One tablet daily, beginning 1-2 days before travel to a malaria-risk area, during the stay, and for 7 days after returning.
Benefits: Highly effective in malaria prevention, especially in areas with drug-resistant malaria strains.

Lariam (Mefloquine) 250mg Tablets

How it helps: Mefloquine works by interfering with the growth of parasites in the red blood cells. It is particularly effective against Plasmodium falciparum, the most dangerous malaria parasite.
Usage: Taken weekly, starting at least one week before travel and continued for 4 weeks after leaving the malaria-endemic region.
Benefits: Provides long-lasting protection and is particularly useful for longer trips to high-risk areas.

These prescription medicines are highly effective in preventing and treating malaria. They work by inhibiting the growth and multiplication of malaria parasites, thus offering travellers and residents in endemic areas vital protection against this potentially deadly disease.

Prevention Strategies

Preventing malaria involves a combination of strategies aimed at reducing the risk of mosquito bites and using preventive medications. Here are some effective steps to help prevent malaria:

● Use of Mosquito Nets Insecticide-Treated Nets (ITNs): Sleeping under ITNs significantly reduces mosquito bites and the risk of malaria. These nets are treated with insecticides that kill mosquitoes on contact.
● Topical Repellents: Apply mosquito repellents containing DEET, IR3535, or Icaridin on exposed skin, especially during evening and night time when mosquitoes are most active.
● Environmental Repellents: Use mosquito coils and vaporizers in living spaces to deter mosquitoes.
● Protective Clothing: Wear long-sleeved shirts and long pants, particularly during the evening and nighttime. Light-coloured clothing is less attractive to mosquitoes.
● Indoor Residual Spraying (IRS): IRS involves spraying the interior walls and other surfaces of a house with insecticides. This kills mosquitoes that rest on these surfaces, thus reducing malaria transmission.
● Medication Before Travel: Consult with a healthcare provider to determine the appropriate chemoprophylaxis medication based on your travel destination. Start the medication before travelling to a malaria-endemic area, continue during your stay, and for a period after returning. Common Medications: Medications like Doxycycline, Atovaquone-Proguanil (Malarone), and Mefloquine are commonly prescribed to prevent malaria.
● Vector Control: This involves treating water bodies with chemicals to kill mosquito larvae, reducing the mosquito population.
● Environmental Management: Remove standing water around living areas to prevent mosquitoes from breeding.
● Travel Precautions: Before travelling to malaria-endemic areas, seek advice from healthcare providers regarding preventive measures and necessary vaccinations.

Awareness of Symptoms: Be aware of malaria symptoms and seek immediate medical attention if symptoms appear, even after returning from a trip.
