Abstract Echovirus type 33 (E33) is a relatively uncommon enterovirus. An E33 outbreak during the winter of 2000 in New Zealand led to 75 virologically‐confirmed cases of E33 infection (2.6 cases per 100,000 individuals). Sixty‐six (88%) of the 75 patients were aged <30 years, with the highest rates of infection recorded in Maori and Pacific ethnic groups. Overall, 47 (84%) of 56 patients whose cases were analyzed had either aseptic meningitis or encephalitis. Central nervous system involvement was more common after infancy (43 of 45 non‐infant patients vs. 4 of 11 infants [relative risk, 2.6; 95% CI, 1.5–4.3]). Two infants died, including a neonate with fulminant hepatitis. Independent of symptom duration, neutrophil‐predominant pleocytosis was detected in 17 (41%) of 41 cerebrospinal fluid specimens. Virus isolates could not be definitively typed by antibody neutralization testing but were identified as E33 by partial sequencing of the VP‐1 capsid gene. The isolates were closely related to strains from Australia and Oman. Molecular typing, together with a serotype‐specific E33 PCR, improved the speed and effectiveness of the outbreak investigation. © 2003 by the Infectious Diseases Society of America
