Prophylaxis of Pneumocystis Pneumonia in. Immunocompromised NonâHIV-Infected Patients: Systematic Review and Meta-analysis of Randomized Controlled Trials. HEFZIBA GREEN, MD; MICAL PAUL, MD; LIAT VIDAL, MD; AND LEONARD LEIBOVICI, MD. OBJECTIVE: To assess the efficacy of prophylaxis for Pneumocystis. pneumonia (PCP), caused by Pneumocystis jirovecii (formerly Pneu-. mocystis carinii), for immunocompromised nonâHIV-infected pa-. tients by conducting a systematic review and meta-analysis.
Incubation period for pink eye caused by virus is around 12 hours to 3 days and a person can go back to work or school when the symptoms improve. That would be in 3 to 5 days. For bacterial infection, the person can go back to work 24 hours after antibiotic has been administered and symptoms start improving.
When pink eye is caused by certain bacteria or viruses, the infected person can be contagious for several days to several weeks or more.Fortunately, people do not appear to be contagious during the incubation period  the time between when they are exposed and when pink eye symptoms begin.lease Share!
