A person who develops malaria symptoms will have to act quickly for a diagnosis. A special doctor, such as an infectious disease specialist, will perform a series of tests to determine whether he or she has malaria.

The cause of malaria is commonly a bite from an infected mosquito, although it is also possible for a person to contract this disease through a blood transfusion, shared needle, or at birth if a mother is infected.

Though it's impossible to entirely eliminate your odds of infection, knowing the risk factors of malaria and taking steps to minimize them is your best chance of prevention. Here are five common malaria risk factors.

The treatment of malaria for a particular patient is determined by three key factors: the species of the infecting parasite; the patient’s clinical situation, for instance, age or pregnancy; and drug susceptibility.

If you have malaria, it may seem like you have a flu, because symptoms are similar. Malaria symptoms commonly begin about 10 days after you've been bitten by an infected mosquito, but they can take months to show.

Malaria is a disease that causes approximately 1 million deaths each year. With this in mind, you should begin preventative measures as soon as possible if you're planning to visit an area that's known for malaria.
