Executive summary

​This issue covers the period from 22 to 28 June 2014 and includes updates on:

West Nile virus

In the past week, Bosnia and Herzegovina reported four new cases of West Nile fever (WNF) from Republika Srpska, all WNV IgM positive. As of 26 June 2014, no WNF human cases were reported in the EU.

During the June-November transmission season, ECDC monitors the situation in the EU and neighbouring countries in order to inform blood safety authorities regarding WNF-affected areas.


There is an ongoing outbreak of measles in the Czech Republic that started in a hospital in Usti nad Labem in February 2014. The outbreak in Catalonia that started in January 2014 is declared over.
During 2014, seven EU Member States have reported measles outbreaks. The target year for measles elimination in Europe is 2015.

 Middle East Respiratory Syndrome Coronavirus

 Since the last CDTR, five additional cases were reported by Saudi Arabia.
Since the beginning of the outbreak in April 2012, 838 cases of MERS-CoV infection have been reported by local health authorities worldwide, including 322 deaths. ECDC published its tenth updated rapid risk assessment on 2 June 2014 and an epidemiological update on 5 June 2014.

Outbreak of Ebola Virus Disease in West Africa

An outbreak of Ebola virus disease (EVD) in West Africa has been affecting Guinea, Liberia and Sierra Leone since December 2013. This is the largest EVD outbreak reported. The risk of infection for travellers is considered very low.
