In cases of<unk>  where influenza A or B are thought to be causative agents, patients who are seen within 48 hours of symptom onset may benefit from treatment with oseltamivir, or zanamivir, or peramivir. Respiratory syncytial virus (RSV) has no direct acting treatments, but ribavirin is indicated for severe cases. Ribavirin has also been known to be used as a treatment for Parainfluenza Virus, and Adenovirus. Herpes simplex virus and varicella-zoster virus infections are usually treated with acyclovir, whilst ganciclovir is used to treat cytomegalovirus. There is no known efficacious treatment for pneumonia caused by SARS coronavirus, MERS coronavirus, or hantavirus. Other forms of care are largely supportive like oxygen supplementation, treatment of comorbidities, and controlling other symptoms, fever and cough, with medications.
