Treatment may be given to relieve symptoms an when necessary, to address anemia.

The prevalence of infection is higher during epidemics - between and with seroconversion rate of 3- (4). Als Rezeptor dient das Erythrozyten-P-Antigen, das von verschiedenen Phänotypen unterschiedlich stark exprimiert wird.
