Malaria, also known as a febrile disease, is one of the world's most dangerous infectious diseases. Once infected, affected individuals require medical treatment with antimalarial drugs. A distinction is made between malaria tropica and malaria tertiana. Malaria is caused by different pathogens. These pathogens are single-celled parasites known as Plasmodium. Five species of Plasmodium can cause malaria in humans: Plasmodium falciparum and Plasmodium vivax are considered the most dangerous malaria parasites, followed by Plasmodium knowlesi, Plasmodium malariae, and Plasmodium ovale. Is Malaria contagious? No, malaria is not transmitted from person to person, except in rare cases such as: Blood transfusions or contaminated needles Transmission from an infected mother to her unborn child Organ transplants How is Malaria transmitted? The main mode of transmission of Plasmodium falciparum, Plasmodium vivax, Plasmodium knowlesi, Plasmodium malariae, and Plasmodium ovale is through the bite of an infected Anopheles mosquito, which injects the malaria parasite (Plasmodium) into the bloodstream. These mosquitoes are primarily active at dusk and during the night. 2. Malaria Symptoms How soon do the first symptoms appear after a malaria infection? Malaria symptoms usually develop 7 to 30 days after infection, but in some cases they may not appear until several months later. What are the typical symptoms of Malaria? This tropical disease is often mistaken for flu or a norovirus infection, particularly in the early stages, as the symptoms – such as chills, high fever, headache and aching limbs, a feeling of weakness, tiredness, as well as nausea, vomiting and diarrhoea – are very similar. However, unlike the flu or a gastrointestinal virus, malaria – depending on the Plasmodium species – can lead to complications such as seizures, kidney failure, circulatory collapse and anaemia within the first 24 hours, which can even be fatal if left untreated. As a general rule, anyone who has come into contact with one of the aforementioned Plasmodium species is at risk of contracting malaria. action medeor supplies health centers in the Democratic Republic of the Congo with essential malaria test kits, enabling local communities to be tested for this dangerous disease.

This is caused by so-called hypnozoites, a dormant form of the parasite that can remain in the liver for extended periods before becoming active and triggering typical malaria symptoms. 3. Distribution and Risk Groups In which countries is the risk of malaria infection particularly high? Malaria is widespread in many tropical and subtropical regions of the world. The disease is especially prevalent in African countries such as the Democratic Republic of the Congo, Malawi, and others, followed by parts of Asia and South America. Travellers occasionally bring the disease back to European countries, including Germany. Who is particularly at risk of infection? Children and pregnant women are especially vulnerable to malaria infection and its potentially severe consequences. Why are poor communities particularly affected by malaria? Alongside AIDS, tuberculosis, and cholera, malaria is considered one of the so-called diseases of poverty. The disease is most common in countries where access to adequate sanitation, healthcare services, and health education is limited. For many people, particularly in sub-Saharan Africa, the costs associated with travelling to health centres or hospitals, as well as the expenses for diagnosis and treatment, remain out of reach. Many families struggle to meet even their most basic needs and cannot afford essential healthcare. This is where action medeor, the “Emergency Pharmacy of the World,” steps in. Through the provision of medicines, diagnostic tools, medical equipment, and support for local healthcare facilities, action medeor helps improve access to life-saving healthcare services for vulnerable communities around the world. Pregnant women and children are among the groups most at risk of malaria infection. Archive photo: Fabrice Mbonankira/action medeor/Fairpicture 4. Prevention and Treatment How can i prevent myself from infection with the Malaria parasite? Anyone planning to travel to a tropical or subtropical country is at increased risk of contracting malaria. Plasmodium falciparum and Plasmodium vivax are among the deadliest malaria parasite species both within and outside Africa. Therefore, anyone planning to travel to countries in Africa, India, or South America should seek advice from a tropical medicine institute or travel health specialist before departure. These experts can provide guidance on appropriate preventive medication and travel health measures. Preventive antimalarial drugs can significantly reduce the risk of infection. In addition to drug-based prevention, exposure prevention is essential. Sleeping areas should be protected against mosquitoes by using window screens and mosquito nets. Mosquito repellents can also help and are often best purchased locally. Furthermore, wearing light-colored, long-sleeved clothing and long trousers can reduce the risk of mosquito bites and help protect against malaria infection. Malaria can be reliably diagnosed using rapid diagnostic tests. However, there is still no vaccine available against this life-threatening disease. Archive photo: action medeor Is there a vaccine against Malaria? No, there is currently no officially approved vaccine against this tropical disease. However, tropical medicine institutes and research organizations have been working on the development of a malaria vaccine for many years. Can Malaria be cured? Yes, malaria is curable if it is diagnosed and treated in time. Anyone who suspects they may have contracted malaria should seek medical attention immediately, ideally from a specialist in tropical medicine. Rapid diagnostic tests can support an initial diagnosis. What does the treatment involve? Treatment may include: Artemisinin-based combination therapies (ACTs) for Plasmodium falciparum (the most dangerous form of malaria) Chloroquine in regions where the parasite remains sensitive to this medication Preventive medication for travellers visiting malaria-risk areas 5. What measures does action medeor take to combat Malaria? The guiding vision of action medeor is that no one should have to suffer from or die of a disease that is preventable or treatable. This includes malaria. To achieve this goal, the humanitarian aid organization based in Tönisvorst supplies everything needed to prevent, diagnose, and treat malaria - from mosquito nets and rapid diagnostic tests to life-saving medicines. These essential resources are delivered directly to the places where they are needed most, particularly health centres and hospitals. In addition, action medeor carries out important health education and awareness-raising activities in affected regions, helping communities understand the risks of malaria and how to protect themselves from this potentially life-threatening disease. action medeor supplies health centres, hospitals and pharmacies in Africa with medicines that are effective against malaria parasites.

For decades, action medeor – the Emergency Pharmacy of the World – has been providing vital assistance in tropical and subtropical regions around the globe. The organization has implemented projects such as this malaria treatment initiative in the Democratic Republic of the Congo projects such as this malaria treatment initiative in the Democratic Republic of the Congo, supplying essential medicines, medical equipment, and technical expertise. Making diseases like malaria preventable and treatable for everyone is at the heart of our mission. However, we depend on support to continue this work. Help us deliver life-saving medicines to remote communities and strengthen the fight against malaria. Together, we can help save lives and improve access to healthcare where it is needed most.
