Enterovirus Surveillance -- United States, 1985

Fifty-six reports were received from state virology laboratories of nonpolio enterovirus (NPEV) isolates identified in March, April, or May 1985. Coxsackievirus B2 was isolated most frequently (18/56), followed by coxsackievirus A9 and echoviruses 6, 7, and 11, with four each, then echovirus 4 and coxsackievirus B5, with three each.

In 1984, the most common isolates were echovirus 9, with 16.7% (266/1,589) of all isolates; echovirus 11, with 9.1%; coxsackievirus B5, with 8.9%; echovirus 30, with 8.3%; coxsackievirus B2, with 7.8%; and coxsackievirus A9, with 7.6%. Reported by Respiratory and Enterovirus Br, Div of Viral Diseases, Center for Infectious Diseases, CDC.

Editorial Note

Editorial Note: A retrospective study of CDC's enterovirus surveillance data from 1970 to 1983 shows that NPEV types isolated in March through May (early isolates) are predictive of types likely to be isolated during the peak enterovirus season (1). In this study, the six most frequent early isolates accounted for an average of 59%, and always more than 50%, of isolates in July through December. Reports of early isolates suggest that coxsackieviruses A9, B2, and B5 and echoviruses 4, 6, 7, and 11 are likely to be common isolates this enterovirus season.
