Non-polio enteroviruses infections are respiratory infections similar to cold spreads from person to person. Non-polio enteroviruses affect millions of people worldwide each year, and are often found in the respiratory secretions (e.g., saliva, sputum, or nasal mucus) and stool of an infected person. Coxsackievirus A16 is the most common cause of hand, foot, and mouth disease (HFMD) in the United States.
The treatment for enterovirus infections is mainly supportive and designed to reduce the symptoms caused by the various enterovirus types. In most of these cases, the baby only develops a mild illness, but rare cases can lead to severe infection. Non-polio enterovirus infection is very common, and it is likely that pregnant women may be exposed to someone with the illness. Like most adults, pregnant women who develop an infection with one of the non-polio enteroviruses will likely have no symptoms of the infection or have only mild symptoms.
