Bacteremia is more likely to occur in immunologically compromised patients (eg, those with HIV / AIDS) and in patients with a hemolytic condition (eg, sickle cell anemia, malaria, Oroya fever), who are also more likely to develop a focal infection, such as infectious arthritis, osteomyelitis, pneumonia, endarteritis (eg, infected aortic aneurysm), endocarditis, urinary tract infection, cholangitis, and meningitis.
