Subject: Re: [ACIPC_Infexion_Connexion] RAT for post covid infection
Hi Leanne,
I hope you’re doing well.
People who have tested positive for SARS-CoV-2 can have detectable virus in upper respiratory secretions for up to 3 months. However, the virus is no longer replicating – and it is highly unlikely individuals are infectious – after around 10 (mild-moderate illness) to 20 days (severe illness) after developing symptoms.
So people who have recently recovered from COVID-19 may test positive on the RAT and the result may be a true positive depending on the timeframe. But this doesn’t mean they are infectious (same as with PCR test).
If a person who had COVID develops symptoms again, and it has been three months since their first infection, they should get a PCR test as it is possible to become reinfected with SARS-CoV-2.
NSW Health recommends against asymptomatic testing (such as surveillance testing) for 6 months after a person has recovered from COVID due to the possibility of a positive result (again, could be true positive but person not infectious). I can’t find a similar recommendation for Victoria but I think this is a good guideline to use.
Cheers
Crystal

Hi All,
Just wondering if anyone has heard data regarding false positive RAT in those that have had covid-19.
We have been informed it is pointless to use RAT on those that have had the virus as they often show false positive results ,
Appreciate all feedback
