ECDC Rapid Risk Assessment highlights young adults and healthcare workers as groups that are susceptible to measles, 21 March 2018
The latest ECDC rapid risk assessment on the risk of measles transmission in the EU/EEA highlights that vaccination coverage and occurrence of cases vary within countries and population groups. It points to the need for systems to identify and vaccinate young adults, who are increasingly affected and therefore increase measles circulation, but who may not be aware of their vaccination status. Finally, ECDC signals the frequency of cases amongst healthcare workers as a matter of concern and suggests that Member States may consider specific interventions to ensure this group is vaccinated.

Salmonella Agona outbreak: infant formula recall to reduce risk to public health
The widespread recall of several infant formula products made by a French processing company is likely to significantly reduce the risk of infants being infected by Salmonella Agona, according to the risk assessment published today by ECDC and the European Food Safety Authority (EFSA). However, as long as there are potentially contaminated products circulating, new cases may still be detected.
