WHO Epidemiological Brief 16: Measles outbreaks, rotavirus surveillance and response to importation of wild poliovirus
For the period January – June 2011, of the 49 countries in the European Region that reported measles data, 39 countries reported a total of 24 493 cases of measles. Due to spread from countries that are experiencing large measles outbreaks, countries that have been measles‐free for many years are now challenged with re-occurrence of the disease.
In 2010, through the WHO/Europe established sentinel surveillance network for rotavirus in six countries, 6 207 children with acute diarrhoea were enrolled and tested for rotavirus. Of these, 2 337 (38%) were rotavirus positive. This proportion on a country‐level ranged from 27% (Azerbaijan) to 48% (Ukraine). The proportion of children who were rotavirus positive increased from 24% among infants aged 0‐5 months to 45% among children aged 12‐59 months. Based on these data, it is evident that rotavirus accounts for a substantial proportion of diarrhoea hospitalizations in all countries within the WHO/Europe network.
