NVSN conducts active, prospective, population-based surveillance for ARI * among children and teens aged <18 years at seven U.S.
The 2 surveillance systems used in Davidson County to assess the impact of influenza disease were the New Vaccine Surveillance Network (
NVSN) and the Emerging Infections Program (EIP).
Differences in the rate estimates between the
NVSN and the EIP systems likely result from the different case-finding methods and the different populations monitored.
The end-of-season hospitalization rate for
NVSN in the previous three seasons ranged from 3.5 (2006-07) to 7.0 (2004-05) per 10,000 children aged 0-4 years.
To summarize rotavirus activity through May 3, during the current 2007-08 season, CDC analyzed data from the National Respiratory and Enteric Virus Surveillance System (NREVSS) and the New Vaccine Surveillance Network (
NVSN).

In years 2000-2006, the end-of-season hospitalization rate for
NVSN ranged from 3.7 (2002-03) to 12 (2003-04) per 10,000 children aged 0-4 years.
Pediatric hospitalizations associated with laboratory-Confirmed influenza infections are monitored in two population-based surveillance networks, the Emerging Infections Program (EIP) and the New Vaccine Surveillance Network (
NVSN).
In addition, no influenza-associated hospitalizations from the EIP or
NVSN surveillance systems have been reported to CDC and no influenza-related pediatric deaths have been reported through the National Notifiable Diseases Surveillance System.
During 2000-2005, the end-of-season hospitalization rate for
NVSN ranged from 3.7 (2002-03) to 12.0 (2003-04) per 10,000 children aged 0-4 years.
During October 30, 2005--March 4, 2006, the preliminary laboratory-confirmed influenza-associated hospitalization rate for children aged 0-4 years in the New Vaccine Surveillance Network ([paragraph][paragraph]) (
NVSN) was 2.1 per 10, 000.
