Enterovirus Surveillance— United States, 1988

(MMWR 1988;37:516) CDC RECEIVED reports of 39 nonpolio enterovirus (NPEV) isolates identified in the United States in March through May 1988 from state virology laboratories. Echovirus 9 was isolated most frequently (nine isolates), followed by coxsackievirus B4 (six isolates), coxsackievirus A9 and echovirus 6 (five each), echovirus 11 (three isolates), and coxsackievirus B1 and echovirus 3 (two each). In 1987, the six most common NPEV isolates were echovirus 6 (169 [16%] of the 1084 isolates), echovirus 18 (144), echovirus 11 (125), coxsackievirus A9 (122), coxsackievirus B2 (83), and echovirus 9 (46). These six NPEV types represented 64% of the total enterovirus isolates reported for 1987. CDC Editorial Note: Since 1970, state health department laboratories have submitted reports on enterovirus serotypes to CDC approximately 6-8 weeks after each specimen is submitted for isolation. CDC's NPEV surveillance data show that isolates from March through May predict the types likely to be isolated
