Effect of the H1N1 Influenza Pandemic on the Incidence of Epidemic Keratoconjunctivitis and on Hygiene Behavior: A Cross-Sectional Study

Background: EKC is transmitted chiefly by direct hand contact. It is suspected that the 2009/2010 influenza pandemic influenced hand washing. This study aims to examine the relationship between the 2009/2010 H1N1 influenza pandemic and hygiene behavior. Methods: We compared the EKC prevalence trends before, during and after the 2009/2010 influenza pandemic by using a t-test comparison of EKC sentinel surveillance. Results: During the pre-pandemic period, the incidence of EKC increased from the 21st to the 44th week each year. However, during the pandemic period in 2009, there was no epidemic peak. In the post-pandemic period, the epidemic curve was similar to that in the pre-pandemic period. Compared to the pre-pandemic period, the total number of EKC patients during the pandemic period showed a decrease of 44.9 % (t value = 27.23, p = 0.002). Comparing the pre-pandemic and pandemic periods by age group, we found there to be a significant decrease in the number of EKC patients for all age groups (24.12#t value#27.23, all P,0.05). This finding was most evident in the teenage group (62%) compared to the other age groups (decreases of 29 to 44%). Conclusions: A continuing effort should be made to educate the public on basic infection prevention behaviors in th

Nosocomial rotavirus infection: An up to date evaluation of European studies

Rotavirus (RV) is worldwide considered as the most important viral agent of acute gastroenteritis in children less than 5 y. Since 2006, the availability of anti-RV vaccines has deeply modified the incidence and economic burden of RV infection. In Europe, some countries have introduced an anti-RV vaccination program in the last 10 y. Although community acquired RV (CARV) disease is the most studied condition of RV infection, recently some authors have highlighted the importance of nosocomial RV (nRV) disease as an emerging public health issue. The aim of this review is to summarize the epidemiology of both CARV and nRV, in order to discuss the difficulty of a clear evaluation of the burden of the disease in absence of comparable data. In particular, we focused our attention to European studies regarding nRV in terms of divergences related to definition, report of incidence rate and methodological issues
