Prophylaxis is the most important measure for decreasing the incidence of PCP, it but does not guarantee protection. Table 4 below delineates the CD4+ indications for starting prophylaxis with regard to the patient's age or status.

PCP prophylaxis should be started in all infants aged 6 weeks who were born to HIV-infected mothers. It should be continued until HIV infection has been ruled out.
