Malaria is a life-threatening disease caused by parasites that are transmitted through the bite of an infected mosquito. It is one of the leading causes of death worldwide and is especially prevalent in tropical and subtropical regions. Symptoms of malaria include fever, chills, headache, nausea, anemia, and in severe cases, organ failure and death. Treatment for malaria includes a combination of drugs, preventive measures, and mosquito control.


The symptoms of malaria usually begin 8 to 25 days after being bitten by an infected mosquito. Symptoms can include fever, chills, sweat, headache, nausea, vomiting, muscle aches, and tiredness. In some cases, malaria can cause seizures, mental confusion, coma, and death. In pregnant women, malaria can result in miscarriage, premature delivery, and death for both mother and baby.


The known causes of malaria are the bite of an infected Anopheles mosquito, contaminated food or water, infected blood transfusions, and mother-to-child transmission during pregnancy. The female Anopheles mosquito is the principal vector for malaria. The mosquito carries and transmits the Plasmodium parasite, which is responsible for causing malaria. When the mosquito bites, the parasite is transferred from its saliva into the bloodstream of the person. The parasite then invades and multiplies inside the red blood cells, causing the symptoms of malaria.

Risk factors

The main risk factors for malaria include:

  1. Living or traveling in areas where malaria is common.
  2. Having a weakened immune system due to certain medical conditions or certain medications.
  3. Poor access to healthcare, particularly in rural areas.
  4. Engaging in activities that expose an individual to mosquito bites, such as camping, fishing, and staying outdoors for extended periods of time.
  5. Living in a house without window screens or other means of mosquito control.
  6. Not using protective measures such as insect repellent, wearing long sleeves and pants, and using bed nets.
  7. Sharing needles when using illegal drugs.


The diagnosis of malaria can be done by examining a blood sample under a microscope to look for the presence of malaria parasites. A rapid diagnostic test (RDT) may also be used to detect the presence of antigens to the malaria parasite. The RDT is a fast, simple and sensitive test that can provide results in as little as 15 to 20 minutes. Other tests such as PCR (polymerase chain reaction) can also be used to detect the presence of malaria in the blood sample.


There are four major subtypes of malaria, which are caused by different species of Plasmodium parasites. These subtypes include Plasmodium falciparum (the most deadly form of malaria), Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae. Plasmodium falciparum is the most virulent form of malaria, and it can cause severe and potentially fatal complications. Plasmodium vivax is the type of malaria that is most commonly found in travelers going to tropical areas. This form of malaria is generally less severe than P. falciparum, but can cause relapses in some patients. Plasmodium ovale is usually milder than P. falciparum and P. vivax, and is most commonly found in Africa and West Asia. Plasmodium malariae is the least common type of malaria, but can still cause severe illness and death.


The treatment options available for Malaria typically depend on the severity of the infection, the species of Plasmodium causing the disease, and where it was contracted. Generally, treatment options include antimalarial medications such as chloroquine, quinine, mefloquine, primaquine, artemether-lumefantrine, doxycycline, atovaquone-proguanil, and proguanil-chloroquine. Other treatments may include intravenous fluids, oxygen, and anticonvulsants. In some cases, supportive care and close monitoring may be needed.


There are several steps that can be taken to reduce the risk of Malaria:

  1. Use insecticide-treated mosquito nets to sleep under at night
  2. Reduce standing water around the home to reduce mosquito breeding grounds
  3. Use insect repellents containing DEET and dress appropriately to reduce exposure to mosquitoes
  4. Wear long-sleeved clothing and pants when outdoors to reduce exposure to mosquitoes
  5. Take anti-malarial drugs when traveling to a malaria-risk area
  6. Get treated for malaria quickly if symptoms appear
  7. Reduce the number of areas with standing water by draining ditches, dikes, swamps, and other areas
  8. Use light traps, mosquito coils, or other methods to reduce mosquito populations
  9. Spray insecticides indoors to reduce the number of mosquitos
  10. 0. Educate people about the importance of preventative measures, such as using insect repellent, wearing protective clothing, and avoiding standing water.

Gender differences?

Yes, there are gender-specific differences in the presentation and management of Malaria. Women typically experience more severe symptoms from the disease and are more likely to develop complications. Additionally, pregnant women and their unborn children are particularly vulnerable to the effects of malaria, as well as other mosquito-borne diseases. In terms of management, there are particular gender-specific differences in access to care, opportunities for prevention, and adherence to treatment. In many countries, women have less access to diagnosis and treatment options due to socio-economic and cultural factors. Women may also be deterred from seeking treatment due to fear of stigma or lack of knowledge. Furthermore, women often have less access to prevention strategies such as insecticide-treated bed nets and indoor residual spraying, as these programs are often administered in a household manner, where male members of the household may have more control. Ultimately, accounting for gender differences in the management of malaria is critical to achieving effective and equitable treatment outcomes.


Nutrition plays an essential role in the management of malaria. Nutritional deficiencies can increase the susceptibility to malaria and make individuals more vulnerable to potentially fatal complications. Malaria can impair the body’s ability to absorb essential nutrients. Malnourished individuals are at a higher risk of becoming infected with malaria, developing more severe symptoms, and having a poorer prognosis if infected. Thus, maintaining a healthy balanced diet with adequate amounts of essential nutrients is important in the prevention, treatment, and management of malaria. This includes increased intakes of iron, zinc, and other essential vitamins and minerals which help to enhance the body’s natural immunity and ability to fight off infection. Additionally, adequate access to food, specifically energy-dense foods and good sources of protein, is essential for the treatment and recovery of malnourished individuals. Providing sufficient energy, along with a nutrient-dense diet, helps to replenish nutrient stores and optimize the body’s ability to fight off malaria.

Physical Activity

Physical activity has been shown to have an indirect effect on malaria. Regular exercise can strengthen the immune system which will help protect against malaria. Additionally, staying active and alert can help people to avoid contact with mosquitoes that carry malaria. Outdoor physical activity also reduces the amount of standing water around the area, which helps to decrease the amount of mosquitoes and reduces the risk of malaria transmission.
