Varies: Malaria reactivation from latent infection form plasmodium ovale or plasmodium vivax can occur three years after an infection. Symptoms in patients with subclinical parasitemia have been reported decades after the initial infection.
Dr. Ed Friedlander

For a lifetime: Especially if not treated, it can keep coming back for decades. We saw this in our World War II personnel long after they returned.

The exposed ones: Malaria is known as tropical disease as it is more prevalent in the tropical climate. People who are exposed to the anopheles mosquitos, known to transport the pathogen of malaria will be more at risk. It's recently been published that people who were born in malaria endemic areas but moved out of those later and now visiting them again, are, in fact, at the highest risk for malaria.

1 week to few months: Malaria symptoms show up a week to a few months after being infected by a mosquito bite. Fevers, chills, fatigue, swelling of the spleen, etc... Usually occur. With medical treatment, the symptoms should go away in a couple of weeks. However, without treatment, and depending on the strain of malaria parasite, an infected person can have symptoms for a few years, up to a few decades.

Dr. Martin Raff
Infectious Disease 56 years experience
Lengthy: Untreated, if not dead, they may last a lifetime. You develop low grade immunity and compensatory mechanisms to deal with damage, but this is seldom cured on its own. Treated appropriately, symptoms will begin to regress within hours of initiation of therapy, but if not fully treated for the extraerythrocytic stages of disease, may recur up to 20 yrs or more after therapy for acute illness.
