Malaria High Fever: Causes, Symptoms, and Treatment


Malaria is a dangerous disease that affects many people around the world, especially in warm areas. It is caused by tiny parasites and spread by mosquitoes. Malaria is a big problem globally, with millions of cases and hundreds of thousands of deaths every year. One of the important signs of malaria is having a high fever. Understanding the connection between malaria and high fever is important for finding the disease early and treating it effectively.

In this article, we will provide simple and clear information about what causes malaria high fever, what symptoms to look out for, and how it can be treated. By knowing more about malaria high fever, we can help people recognize the signs and get the right help quickly. This can make a big difference in fighting the disease and saving lives.

What is Malaria?

Malaria is a disease that mosquitoes spread. It happens when tiny parasites called Plasmodium enter our bodies through mosquito bites. These parasites travel to the liver and then invade red blood cells, causing malaria symptoms. Malaria is most common in warm areas like Africa, Asia, and parts of Latin America. These regions have lots of mosquitoes that carry the disease, so they have the most cases. The mosquitoes that spread malaria are called Anopheles mosquitoes. When they bite someone with malaria, they suck up the parasites along with the person’s blood. Inside the mosquito, the parasites grow and become infectious. When the infected mosquito bites someone else, it passes the parasites on, continuing the cycle.

Anopheles mosquitoes are a big concern because they usually bite in the evening and at night when people are indoors and more likely to get bitten. To prevent malaria, we need to control these mosquitoes and protect ourselves from their bites. Using insecticide-treated bed nets, spraying insecticides inside homes, and other mosquito control methods can help stop the spread of malaria.

The Link Between Malaria and High Fever:

Having a high fever is a common sign of malaria, which helps us identify the disease. When someone gets infected with malaria parasites, their immune system reacts to fight off the invaders. This immune response causes the body to release special chemicals called cytokines. These cytokines make the body’s temperature go up, resulting in a fever. The rise in body temperature during malaria is actually a good thing. It creates an environment that is not suitable for the malaria parasites to survive and grow. Additionally, the higher temperature helps the immune cells work better to get rid of the parasites.

During a malaria infection, the body’s metabolism increases, producing more energy and heat. This, combined with the effects of the cytokines on the body’s temperature control, leads to a higher body temperature or fever. The severity of the fever in malaria can vary, ranging from mild to high. It is often accompanied by chills and sweating. In some cases, the fever may come and go in a pattern, with periods of high temperature. It’s important to remember that high fever can also be a symptom of other illnesses, not just malaria. That’s why it is important to look for other signs like headache, muscle pain, tiredness, and consider if the person has been to areas where malaria is common.


Understanding the link between malaria and high fever is important for us because it helps us identify the infection early and start the right treatment. Seeking medical help promptly, getting an accurate diagnosis, and taking the proper antimalarial medications can control the infection, relieve symptoms, and prevent serious complications.

Causes of Malaria High Fever:

Malaria high fever happens because of tiny parasites called Plasmodium. These parasites invade our red blood cells and make us sick with malaria, causing symptoms like fever. There are four main types of Plasmodium parasites that can give us malaria: Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, and Plasmodium ovale. Each type can cause different levels of fever.

  1. Plasmodium falciparum is the most dangerous and widespread type. It causes high fever and can lead to severe complications. It’s the one we need to worry about the most.
  2. Plasmodium vivax is another common type. It usually causes less severe symptoms but can give us recurring fevers. That means we might have fever episodes even after getting treatment.
  3. Plasmodium malariae is not as common, and it usually gives us milder and less frequent fevers compared to the other types.
  4. Plasmodium ovale is rare but can also cause fever. It’s similar to Plasmodium vivax and can bring back fevers repeatedly.

The life cycle of these parasites inside our bodies is complex. When a mosquito bites us, it puts the parasites into our blood. They then travel to our liver and multiply. Later, they go back into our bloodstream and invade red blood cells. Inside the red blood cells, the parasites multiply and make more of themselves. This leads to the cells bursting and releasing more parasites into our bloodstream. This cycle of invasion, multiplication, and bursting causes the fever to come and go.

Symptoms of Malaria High Fever:

Malaria high fever is often accompanied by various other symptoms that can help identify the disease. While the specific symptoms may vary among people and depending on the type of Plasmodium parasite causing the infection, there are several common signs to look out for.

  1. Fever: High fever is a hallmark symptom of malaria. It typically presents with chills, rigors (shivering), and sweating. The fever may come in cycles, with periods of spikes followed by temporary relief.
  2. Headache: Many people with malaria experience severe headaches, which can be persistent and throbbing.
  3. Fatigue: Malaria can cause extreme tiredness and weakness, leading to a general feeling of exhaustion.
  4. Muscle and Joint Pain: People infected with malaria often complain of muscle aches and joint pain. These symptoms can be widespread or localized and may vary in intensity.
  5. Nausea and Vomiting: Malaria can cause gastrointestinal symptoms, including nausea and vomiting.
  6. Loss of Appetite: Many people with malaria experience a decreased desire to eat.
  7. Abdominal Pain: Some people may experience abdominal discomfort or pain, which can be associated with enlargement of the spleen or liver.
  8. Diarrhea: In some cases, malaria can lead to diarrhea, which can contribute to dehydration.
  9. Anemia: Malaria can cause a decrease in red blood cells, leading to anemia. This can result in weakness, pale skin, and shortness of breath.
  10. Jaundice: In severe cases, malaria can affect the liver and lead to jaundice, characterized by yellowing of the skin and eyes.

Note that the symptoms of malaria can be different depending on the severity of the infection.

Untreated Malaria Life-Threatening Complications

As malaria progresses, it can cause severe complications, such as:

  1. Severe Anemia: The destruction of red blood cells can lead to a significant decrease in hemoglobin levels, resulting in severe anemia. This can impair oxygen delivery to tissues and organs.
  2. Cerebral Malaria: In some instances, malaria parasites can affect the brain, leading to a condition known as cerebral malaria. It can cause seizures, confusion, coma, and neurological deficits.
  3. Organ Dysfunction: Severe malaria can damage vital organs such as the liver, kidneys, and lungs, leading to organ dysfunction and failure.
  4. Respiratory Distress: Severe malaria can cause acute respiratory distress syndrome (ARDS), which leads to breathing difficulties and can be life-threatening.
  5. Circulatory Collapse: In rare cases, severe malaria can lead to circulatory collapse and shock, requiring urgent medical intervention.

It is important to seek medical attention promptly if malaria is suspected, especially in high-risk areas. Early diagnosis and appropriate treatment can help prevent complications and ensure a faster recovery.

Diagnosis and Treatment for Malaria High Fever:

When it comes to malaria high fever, diagnosing the disease correctly and starting treatment promptly are important for a successful recovery. Doctors employ various methods to diagnose malaria and determine the appropriate treatment approach.


  1. Microscopy: The traditional method of diagnosing malaria involves examining a small sample of blood under a microscope. By looking for malaria parasites in the blood cells, doctors can confirm the presence of the disease.
  2. Rapid Diagnostic Tests (RDTs): RDTs are convenient tools for diagnosing malaria. These tests detect specific antigens produced by the malaria parasites in a person’s blood. RDTs provide quick results, usually within 15-20 minutes, enabling doctors to initiate treatment promptly.


  1. Antimalarial Medications: The choice of antimalarial medication depends on factors such as the type of malaria parasite, the severity of the infection, and any drug resistance patterns in the region. Commonly used antimalarial medications include:
    • Artemisinin-based Combination Therapies (ACTs): ACTs are highly effective and are recommended as the first-line treatment for uncomplicated malaria. They typically consist of a combination of drugs, including an artemisinin derivative, which rapidly kills the malaria parasites.
    • Chloroquine: Chloroquine used to be the primary treatment for malaria. However, its effectiveness has decreased due to the emergence of drug-resistant strains of the malaria parasite, particularly Plasmodium falciparum.
    • Other Antimalarial: Depending on the specific circumstances, doctors may use alternative antimalarial medications, such as mefloquine, atovaquone-proguanil, or quinine, to treat malaria infections.
  2. Supportive Care: In addition to antimalarial medications, supportive care measures can help manage symptoms and aid in the recovery process. These include:
    • Hydration: Drinking plenty of fluids, such as water, helps prevent dehydration, especially if there is associated vomiting or diarrhea.
    • Rest: Getting adequate rest allows the body to recover and supports the immune system in fighting the infection.
    • Fever Management: Over-the-counter medications like acetaminophen (paracetamol) can be used to reduce fever and alleviate discomfort.

Final Thoughts

Malaria high fever is a significant health concern, particularly in regions where the disease is prevalent. Early diagnosis and timely treatment are important for effective management and successful recovery. By understanding the causes, symptoms, and treatment options for malaria high fever, people can take appropriate measures to protect themselves and seek medical help promptly when needed.

Malaria is a mosquito-borne disease caused by parasites, primarily transmitted through infected Anopheles mosquitoes.
