Yersinia Isolates 2020

Monday 21st June 2021


The year 2020 has been unusual at best for everyone and the enteric data for 2020 will always stand apart from other years due the multiple effects of our COVID 19 response on our national data.

When NZ locked down at the end of March 2020, diagnostic laboratories staff and resources were given over to the task of establishing and performing testing for COVID 19. Therefore diagnostic laboratories were actively discouraging referral of other, more routine work. This coupled with people staying home in small bubbles; not eating out; and not being able to readily access face-to-face medical assistance meant that for a period of two months there were very few enteric pathogens received at ESR for typing.

Once NZ moved back to Alert Level 2, enteric testing and isolate referral gradually recommenced and Yersinia numbers returned to the levels expected compared with previous years suggesting that the vast majority of NZ cases are locally acquired.
A comprehensive review of Yersiniosis in New Zealand was published by ESR staff in Pathogens in February 2021:
