Malaria is primarily spread when an infected mosquito bites a non-infected person. The malaria parasites travel through the bloodstream and travel to the liver. After the parasites mature, they multiply in red blood cells, destroying them.

Malaria is not contagious person to person.

Symptoms are delayed, first occurring 7-30 days after infection and generally last 6-10 hours and cycle every 2 to 3 days. Malaria symptoms include shivering, fever, headache, vomiting, sweating, seizures, and fatigue. When left untreated, malaria can become severe and cause death.

Malaria transmission occurs across 87 countries and territories.  The map below, provided by the Centers for Disease Control and Prevention, shows an approximation of the parts of the world where malaria transmission occurs.

Atovaquone:Proguanil is a more affordable, generic form of Malarone that is just as effective.

Atovaquone:Proguanil (generic Malarone) works by interfering with the growth and reproduction of the malaria parasites in the body. Atovaquone and proguanil work together to target different stages of the parasite's life cycle, making it an effective prophylactic medication.

Atovaquone:Proguanil (generic Malarone) is effective against most types of malaria, including Plasmodium falciparum, which is the most common and dangerous form of the disease.

Although the exact dosing instructions will be provided by your healthcare provider, in general, it is recommended to start taking atovaquone:proguanil (generic Malarone) 1-2 days before entering the malaria zone, continue taking it daily during your stay, and then continue for 7 days after leaving the area.

While this medication helps prevent malaria, it does not provide protection against mosquito bites. It is still important to take additional measures to avoid mosquito bites, such as using insect repellents, wearing long sleeves and pants, and staying in screened or air-conditioned accommodations.
