Executive summary

​West Nile Fever - Europe
As of 25 June 2015, one human case of West Nile fever has been reported by Bulgaria. This probable case (as per the EU case definition) is the first case reported in the European region for the current transmission season (June to November). ECDC publishes weekly West Nile fever risk maps to inform blood safety authorities regarding affected areas.

Measles - Europe 
2 203 measles cases have been reported in Germany during the first 22 weeks of 2015, according to the latest epidemiological bulletin of the Robert Koch Institute. The outbreak in Berlin, where most cases (1 141) were notified, is subsiding – with 12 reported cases during the last week (down from 156 in week 12). Seven of the 16 German states reported no cases this week, an improvement from week 20 when only two states reported no cases.
 
During the last month, new measles outbreaks were detected in Sweden, Belgium and Lithuania.

Cluster of schistosomiasis - France 
In April 2014, a cluster of Schistosoma haematobium infections was detected linked to exposure in the Cavu river, a natural swimming area in Southern Corsica, France. Epidemiological investigations led to the detection of 110 cases of Schistosoma haematobium infections (as of 25 March 2015), including 33 residents from Corsica. The majority of the cases have been recorded among children or teenagers.
 
These were the first locally-acquired infections of Schistosoma haematobium in the EU. However, geographical distribution of the disease is usually limited so the risk of acquiring the infection exists only for residents and travellers visiting the affected areas that have contact with infested water.

Middle East respiratory syndrome – MERS
Since April 2012 and as of 24 June 2015, 1 373 cases of MERS have been reported by local health authorities worldwide, including 528 deaths. South Korea reported 14 additional cases and 5 deaths over the last week. Overall, the number of new cases reported decreased during the last two weeks.
