Shigella Isolates 2017

Wednesday 22nd March 2023


Shigella referral numbers have again increased this year with isolates confirmed from 239 cases compared with 156 in 2016, and 112 in 2015.

Shigella sonnei biotype g remains the most common NZ type, with the emergence of Shigella flexneri 6 Boyd 88 and Shigella flexneri 1b pushing our historically most common type - Shigella sonnei biotype a - to 4th most common for the year. We note that a travel history which includes Tonga appears associated with Shigella flexneri 1b.
