General bacterial and protozoal outbreaks of infectious intestinal disease reported to HPS in 2017

During 2017, three general outbreaks of shiga-toxigenic Escherichia coli (STEC) were reported; these were due to three different serogroups one each of O157, O145 and O26. This is comparable to the number of STEC outbreaks seen in previous years, with an average of five outbreaks per year over the previous five years (2012-2016).
