Malaria is a well-known tropical disease that affects millions of people worldwide. While it is commonly associated with countries in Africa, Asia, and Latin America, malaria is also present in some parts of the United States.

Understanding Malaria: Malaria is a life-threatening disease caused by parasites transmitted to humans through the bites of infected female Anopheles mosquitoes. These mosquitoes are primarily active during the night, putting individuals at risk while they sleep. The disease can manifest with symptoms such as fever, chills, headache, fatigue, and muscle aches. If left untreated, it can progress to severe complications and even death, particularly among young children, pregnant women, and individuals with weakened immune systems.

Locally acquired malaria in the USA: Malaria cases in the United States are primarily attributed to travel-related infections. Travelers who visit malaria-endemic regions and are bitten by infected mosquitoes can develop the disease and subsequently transmit it to others through local mosquito bites.
The mosquitoes that transmit locally acquired malaria are called Anopheles mosquitoes. These mosquitoes breed in warm, standing water, such as in puddles, birdbaths, and flower pots. They are most active at night.

Prevention Methods:

  1. Mosquito Avoidance: Minimizing exposure to mosquito bites is a fundamental aspect of malaria prevention. Use mosquito nets while sleeping, preferably those treated with insecticides, as they provide an effective physical barrier. Additionally, consider installing window screens and using insect repellents containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin. You can buy some Mosquito Repellent products here.
  2. Antimalarial Medications: If you are traveling to a malaria-endemic region, consult a healthcare professional or a travel medicine specialist well in advance. They can provide you with appropriate antimalarial medications based on the destination, the duration of your stay, and your medical history. Remember to strictly adhere to the prescribed dosage and duration of the medication.
  3. Environmental Control: Mosquitoes breed in stagnant water, so it is essential to eliminate potential breeding sites around your home and surrounding areas. Regularly empty and clean water containers, cover open water storage tanks, and avoid leaving uncovered water sources. Insecticides can be used in standing water bodies where larvae may be present.

  4. Protective Clothing: Wearing long-sleeved shirts, long pants, and socks can provide an additional layer of protection against mosquito bites. Light-colored clothing is recommended, as mosquitoes are attracted to dark colors.
  5. Time and Place Precautions: Be aware of the peak biting times of malaria-transmitting mosquitoes, which are typically during dusk and dawn. If possible, limit outdoor activities during these periods. Moreover, try to stay in accommodations with air conditioning or screened windows and doors to keep mosquitoes out.

Community Efforts: Malaria prevention is not solely an individual responsibility but also requires community-wide efforts. Governments, healthcare organizations, and communities in affected areas play a crucial role in implementing mosquito control programs, distributing bed nets, and ensuring access to proper diagnosis and treatment. Supporting and participating in such initiatives can contribute to reducing the overall burden of malaria.

Symptoms of malaria

The symptoms of malaria typically appear 10-15 days after being bitten by an infected mosquito. However, the symptoms can appear as early as 7 days or as late as 40 days after being bitten.
The most common symptoms of malaria are fever, chills, sweats, headache, muscle aches, and fatigue. In some cases, malaria can also cause nausea, vomiting, diarrhea, and cough.

Prompt Diagnosis

If you have traveled to a malaria-endemic region and develop symptoms such as fever, chills, headache, and fatigue, it is crucial to seek medical attention promptly. Malaria can rapidly progress and become life-threatening if left untreated. Inform your healthcare provider about your recent travel history, as this information will help guide the diagnosis and treatment process.

Diagnosis of malaria involves a blood test to confirm the presence of the Plasmodium parasite. The healthcare provider will determine the species of the parasite, which is important for selecting the appropriate treatment regimen.

Treatment for malaria

The treatment of malaria in the USA typically involves the use of antimalarial medications. The choice of medication depends on several factors, including the species of the Plasmodium parasite, the severity of the infection, and the individual’s overall health.

  1. Chloroquine and Hydroxychloroquine: These medications are commonly used for the treatment of uncomplicated malaria caused by certain species of the parasite. However, due to the emergence of drug-resistant strains of malaria, the effectiveness of these drugs may be limited in certain regions.
  2. Artemisinin-Based Combination Therapies (ACTs): ACTs are considered the most effective treatment for uncomplicated malaria caused by Plasmodium falciparum, the most severe malaria parasite. These combination therapies usually consist of an artemisinin derivative combined with another antimalarial drug. ACTs are highly effective in clearing the parasite from the bloodstream and preventing the development of drug resistance.
  3. Other Antimalarial Medications: In some cases, alternative antimalarial medications may be prescribed based on the specific species of the parasite and drug resistance patterns. These medications include atovaquone-proguanil, quinine, mefloquine, and primaquine. The choice of medication will be determined by your healthcare provider based on various factors.

Current situation of malaria in the USA

In 2022, there were 1,677 cases of malaria reported in the United States. Of these cases, 1,661 were imported malaria and 16 were locally acquired malaria. The locally acquired cases occurred in Florida, Texas, and Georgia.
The risk of getting malaria in the United States is very low. However, it is important to be aware of the disease and take steps to prevent it, especially if you are traveling to a malaria-endemic area.


Although malaria is not endemic in the United States, it remains a concern due to travel-related infections. Understanding the types of malaria and taking appropriate preventive measures can significantly reduce the risk of contracting the disease. If you are planning to travel to a malaria-endemic region, consult a healthcare professional, and adhere to their recommendations for malaria prevention. By staying informed and taking proactive steps, you can protect yourself and contribute to the overall effort of reducing the impact of malaria in the United States.
