Hand-Foot-and-Mouth Disease: Rapid Evidence Review

Hand-foot-and-mouth disease is caused by human enteroviruses and coxsackieviruses. Outbreaks can occur in the spring to fall and are common in North America, and most cases occur in patients younger than 10 years. Hand-foot-and-mouth disease is transmitted by fecal-oral, oral-oral, and respiratory droplet contact. Patients present with a low-grade fever, a maculopapular or papulovesicular rash on the hands and soles of the feet, and painful oral ulcerations. Lesions usually resolve in seven to 10 days; however, in rare cases, patients may have neurologic or cardiopulmonary complications. The differential diagnosis for childhood rashes and oral enanthems is broad and includes erythema multiforme, herpes, measles, and varicella. Treatment is supportive and directed toward hydration and pain relief as needed with acetaminophen or ibuprofen. Oral lidocaine is not recommended, and antiviral treatment is not available. The best methods to prevent the spread of hand-foot-and-mouth disease are handwashing and disinfecting potentially contaminated surfaces and fomites.
