The Ministry of Health has today updated its advice for those who experience COVID-19 symptoms more than 28 days after having had COVID-19.
If a person develops new COVID-19 symptoms, and it is 29 days or more since their previous infection, it is possible that they are experiencing a COVID-19 reinfection and they should get tested.
This reflects a change from earlier advice which was that people would not need to re-test if they had tested positive for COVID-19 within the past 90 days.
Anyone taking the test should upload their results to MyCovidRecord. Should they test positive, and it has been more than 28 days since they last had COVID-19, they will need to isolate for 7 days.
This is because there remains a small chance of catching COVID-19 again within 90 days of a first infection, especially if it is a different variant or sub-variant.
If it is 28 days or less since a recent infection, a test is not needed.
The Ministry of Health is constantly reviewing the national and international evidence on reinfections. However, evidence and infection rates vary greatly between countries and the data is very sparse.
New Zealand’s experience with COVID-19 has taught us a lot about how effective public health measures are at protecting us from other airborne viruses, such as the flu. Let’s keep practising these throughout winter to keep ourselves and our communities safe.
Book your flu vaccination if you have not already done so. The flu vaccine is free to anyone 65 and older, Māori and pacific people 55 and over, and for children aged 3-12.
