Hepatitis B vaccination coverage among Iranian children aged 15-26 months in 2006.

This study in 2006 estimated the hepatitis B virus (BHV) vaccination coverage in the Islamic Republic of Iran at the national and district levels in urban, rural and remote populations of 41 university health service areas. Of 21 905 children recruited to the study, vaccination coverage based on vaccination card records was 100% in 14, 15 and 10 of the 41 university areas for the 1st, 2nd and 3rd doses of HBV respectively. National levels of HBV1, HBV2 and HBV3 coverage were 98.9%, 98.8% and 98.4% respectively. The lowest HBV vaccination coverage rate was 90.7% (in a remote district). HBV vaccination coverage was at an acceptable level in Iranian children.

Sentinel hospital-based surveillance of rotavirus diarrhea in iran.

BACKGROUND: Rotavirus is the most common causes of severe, acute diarrhea during childhood and is an important cause of morbidity and mortality in developing countries. We established active hospital-based surveillance of childhood diarrhea to assess the scope of severe rotavirus disease in Iran. METHODS: From May 2006 through April 2007, prospective surveillance of rotavirus diarrhea among children aged <5 years was conducted in 5 sentinel hospitals in Iran. Stool samples were tested for rotavirus using a commercially available enzyme immunoassay, and rotavirus-positive samples were genotyped using reverse-transcriptase polymerase chain reaction. RESULTS: Of 2198 children admitted to the hospital for acute gastroenteritis, 1298 (59.1%) had stool samples test positive for rotavirus by enzyme immunoassay. Of the rotavirus episodes, 85% occurred during the first 2 years of life, with the peak prevalence of severe rotavirus disease occurring from September through January. Among the 110 rotavirus-positive samples that were genotyped, G4P[8] was the most commonly detected rotavirus genotype (30.9% of strains). Other commonly detected genotypes included P[8] with G nontypeable (21.8%), G4 with P nontypeable (13.6%), G1[P8] (10.9%), and G2[P4] (5.5%). CONCLUSIONS: Rotavirus is the most common cause of severe diarrhea in Iran, which indicates that safe and effective rotavirus vaccination in Iran is a public health priority.
