To track progress toward achieving the goals of the Childhood
Immunization Initiative (CII), CDC publishes quarterly a tabular
summary (Table_1) of the number of cases of nationally
notifiable
diseases preventable by routine childhood vaccination reported
during
the previous quarter and year-to-date (provisional data). In
addition,
the table compares provisional data with final data for the
previous
year and highlights the number of reported cases among children
aged
less than 5 years, who are the primary focus of CII. Data in the
table are reported through the National Electronic
Telecommunications
System for Surveillance (NETSS).

Number of reported cases of nationally notifiable diseases preventable by routine childhood vaccination -- United States,

* Data for 1995 are final and for 1996 are provisional.
+ For 1995 and 1996, age data were available for >=94% of cases, except for 1996 age data for measles, which were
available for 89% of cases.
& Invasive disease; H. influenzae serotype is not routinely reported to the National Notifiable Diseases Surveillance System.
Of 277 cases among children aged <5 years, serotype was reported for 95 cases, and of those, 31 were type b, the only
serotype of H. influenzae preventable by vaccination.
@ Because most hepatitis B virus infections among infants and children aged <5 years are asymptomatic (although likely to
become chronic), acute disease surveillance does not reflect the incidence of this problem in this age group or the
effectiveness of hepatitis B vaccination in infants.
** Five suspected cases with onset in 1996 have been reported to date. One additional suspected case with onset in 1995 is
under investigation.
