Coxsackie and echoviruses belong to a class known as enteroviruses.
Coxsackie and echoviruses infections are often asymptomatic.
Coxsackie viruses are divided into groups A and B.
Coxsackie A viruses are mainly associated with human hand, foot and mouth disease.
Coxsackie Bviruses can cause mild signs and symptoms, similar to a "cold", but these viruses also can lead to more serious diseases, including myocarditis (inflammation of the heart); pericarditis (inflammation of the sac lining the heart); meningitis (inflammation of the membranes that line the brain and spinal cord); and pancreatitis (inflammation of the pancreas).
Infection is common but most frequent in summer and autumn in temperate climates but all year round in the tropics. They tend to affect those under 16 but adults are also affected. Spread is usually from the faeco-oral route with an incubation period of 2 to 6 days.
Echoviruses, on the other hand, are a cause of many of the non-specific viral infections. It is mainly found in the intestine, and can cause nervous disorders. |
