<Emphasis Type="BoldItalic">Pneumocystis Jirovecii</Emphasis> Pneumonia: Current Knowledge and Outstanding Public Health Issues

Antiretroviral therapy and cotrimoxazole prophylaxis have caused a decline in Pneumocystis jirovecii incidence in developing countries since the 1990s. Nevertheless, Pneumocystis jirovecii pneumonia (PCP) remains the primary AIDS-defining disease around the world. Much about the disease remains unknown, including its global burden, best diagnostic practices, the frequency of drug resistance, and the risks associated with Pneumocystis colonization. This review describes current knowledge about Pneumocystis infection and highlights areas where new research could benefit public health.
