Description

While the risk for severe malaria in endemic areas is greater in children, the risk is different for a nonimmune individual. This has implications for tourists from developed countries who travels to an endemic area. The authors are from the TropNetEurop and SIMPID surveillance groups.


 

Patient selection: nonimmune patient with falciparum malaria

 

Outcomes in severe malaria:

(1) cerebral malaria

(2) prolonged hospitalization

(3) death

 

Risk factors for severe malaria:

(1) age >= 40 years of age, with significant risk if >= 70 years of age (Table 2, page 993).

(2) female gender (for cerebral malaria)

(3) failure to take chemoprophylaxis

 

where:

• In the discussion an age >= 60 ("old age") was considered a risk factor for severe malaria. In the implementation I will assign 1 point for 40 to 59, 2 points for 60 to 69 and 3 points for >= 70 years of age.

• The discussion on page 994 links comorbid disease to age and the risk of severe disease, but this did not appear to be included in the data analysis. I will add severe comorbid disease as a risk factor in the implementation.
