The incidence and distribution of reported varicella cases in the Rijeka District (RD), Croatia (323,130 inhabitants in 1990 and because of the new administrative distribution 305,505 inhabitants in 1991), from 1977 to 2012 are presented. During this period, varicella is continuously present in the RD and these epidemics appear practically every other year. The highest incidence of 1642 per 100,000 inhabitants was registered in 1987. High incidence was also registered during the interepidemic years, while the lowest 247 per 100,000 inhabitants was registered in 2001. Children between the ages of 5 and 9 years were mostly infected, while 87.7% of the 78,883 registered cases were in those up to 14 years. Varicella manifests most intensively during winter and spring, with a peak in March and April. Males are not significantly more affected (51.1%) than females (48.9%). In the observed period, there was not a single reported case of death connected with the varicella disease.
