Antibiotics: their true place in the treatment of viral disease.

The use of antibiotics in viral diseases of childhood is discussed. If bacterial infection is likely, either as superinfection or as part of the differential diagnosis, then antibiotics should be given. The antibiotic of choice for each illness is considered. Respiratory infections are common. The diagnosis and treatment of streptococcal pharyngitis is compared with viral pharyngitis. Penicillin is indicated if the bacterial infection is possible. If there is difficulty in distinguishing between croup and epiglottitis, then chloramphenicol or ampicillin should be given. Otitis media and pneumonia caused by viruses are difficult to differentiate from their bacterial counterparts, and antibiotics are indicated. By contrast, antibiotics are not used in bronchiolitis or asthma. Antibiotics are contraindicated in gastroenteritis even if caused by bacteria. Prolongation of the carrier state or superinfection may then occur. Interpretation of the biochemical and bacteriological findings of the cerebrospinal fluid is important in distinguishing viral meningitis and encephalitis from bacterial meningitis. If bacterial meningitis is possible, then antibiotics should be used. The indications for antibiotics in viral diseases of the skin, eye, joints, heart and parotid are also discussed.
