We report a molecular typing and epidemiologic analysis of Pneumocystis carinii pneumonia (PCP) cases diagnosed in our geographic area from 1990 to 2000. Our analysis suggests that transmission from patients with active PCP to susceptible persons caused only a few, if any, PCP cases in our setting.

Five cases of pneumocystis carinii pneumonia were diagnosed in adult patients following intensive chemotherapy in the Royal Group of Hospitals haematology unit, Belfast, within a space of six months. The common features and the risk factors contributing to the increased susceptibility of these patients are discussed, as are the likely mechanisms of transmission of infection.
