* Verocytotoxin-producing isolates (data from PHE’s VTEC Enhanced Surveillance System).

** Data from PHE’s Second Generation Surveillance System (SGSS). These data include salmonella infections for which no serovar result is available (ie non-serotyped salmonella spp.) and which therefore are not directly comparable to data reported before 2015.

¥ This is, in part, due to higher numbers earlier in this season raising the cumulative number of laboratory reports. However laboratory reports for the most recent weeks are comparable to those seen in the other post-vaccine seasons.
