Within the context of the West Nile virus outbreaks, an ECDC mission was conducted at the end of the transmission season to support the Greek authorities regarding further response and prevention activities on West Nile virus infections.
In May 2011, the European Commission asked ECDC to estimate the change in total exposure risk to hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV) during reproductive cell handling and storage for secondary parties, if the current scheme of testing at each cell donation would change to testing partner donors of reproductive cells once or twice a year.
Following a request by the Romanian government, ECDC conducted a second follow-up country visit to Romania covering HIV, sexually transmitted infections (STIs) and hepatitis B and C from 11–13 May 2011.
Following a request by the Estonian government, ECDC performed a follow-up country visit to Estonia covering HIV and sexually transmitted infections (STIs) from 11–13 October 2010.
Following an unusually large and widespread outbreak of West Nile virus, ECDC and the WHO Regional Office for Europe conducted a joint visit to Romania to review the risk assessment of the virus in Romania.
