What is the prognosis of malaria?
If diagnosed early and if the appropriate antibiotics are available and used, the prognosis of malaria is very good.
Worldwide malaria is responsible for 500,000-800,000 deaths per year. The majority of victims are young children from sub-Saharan Africa. Death is usually due to lack of available treatment or access to treatment.
P. falciparum tends to be the species causing the most complications and has a high mortality if untreated.
Cerebral malaria, a complication of P. falciparum malaria, has a 20% mortality rate even if treated.
Is there a malaria vaccine?
There is currently no vaccine available to prevent malaria. Due to the diversity of the Plasmodium species and the P. falciparum species being the most deadly parasite, most efforts are currently directed toward a P. falciparum vaccine.
In 2013, an early stage vaccine trial showed some success.
Can malaria reoccur after treatment?
P. vivax and P. ovale can hibernate in the liver and cause relapsing disease weeks or months after the patient is symptom free.
