Late on Friday 14 May, ESR reported there had been a weak positive test result from a sample taken in Wellington. A follow-up sample yesterday returned a second weak positive result.
Based on our experience, it is most likely that the two weak positive results are due to recently recovered cases continuing to shed the virus.
In recent weeks three recovered cases who live in the Wellington region have left the Auckland quarantine facility. A further historical case left a Wellington managed isolation facility the same day the second sample was taken.
Additionally, it is possible that one or more recently recovered cases from elsewhere could have flown into Wellington.
ESR consider a single recovered person shedding the virus may be detected in wastewater.
As part of our ongoing precautionary approach, and to help rule out undetected COVID-19 infection, the Ministry is encouraging anyone with symptoms, especially if they are in the Wellington region to get tested promptly.
This advice also applies to recent visitors to the Wellington region. Anyone who develops symptoms consistent with COVID-19 should call Healthline on 0800 358 5453 or their doctor, or visit a testing station to get a test.
