Complications
Enteroviruses occasionally cause severe complications, especially cardiac and neurologic complications. These include the following:
- Myocarditis
- Aseptic meningitis: Nonpolio human enteroviruses are the leading recognizable causes of aseptic meningitis, accounting for 80-92% of all cases in which a pathogen is identified. Certain enteroviruses (eg, coxsackie B virus 5; echoviruses 6, 9, and 30) are more likely to cause meningitis outbreaks, while others (coxsackie A virus 9, coxsackie B viruses 3 and 4) are the cause of endemic aseptic meningitis.[27]
- Meningoencephalitis
- Sepsis[28]
- Hepatitis
- Disseminated intravascular coagulation
- Paralysis
Coxsackievirus infections in pregnancy have been associated in several studies with increased rates of type 1 diabetes mellitus in the offspring. Additionally, maternal coxsackie B virus infection during pregnancy may increase the rate of cardiac anomalies.[29] Enteroviral infection acquired during the first trimester of pregnancy may result in spontaneous abortion
Prognosis
In general, the systemic and cutaneous manifestations of enteroviruses in immunocompetent individuals are self-limited. Cutaneous lesions heal without scarring. Mortality rates ranging between 0-42% in the neonatal period. Risk factors for severe infection are as follows:
- Prematurity
- Maternal viral symptoms at delivery
- Symptoms in the first week of life
- No specific antibodies (acquired by placental transfer) of the infecting serotype in the neonate[2]
A few cases of prolonged or recurrent hand-foot-and-mouth disease (HFMD) have been reported. In 1964, Evans and Waddington[30] reviewed a large outbreak in South Wales. They described a relapsing course occurring over 2 years in one patient.
