So MIL could have it and be contagious now?
Yep, she should get a PCR ASAP and you'll know for certain when it comes back. Sometimes (though v v rarely) it can be inconclusive because they dropped it.
The odds of spreading the new variant in households is a touch lower and with boosters, your elderly relative will hopefully be okay. If its inconclusive today, then there is a chance she is positive but not contagious today (if its only been 24 hours).
Our timeline last year:
DP got the PCR test midday 22nd
Got the inconclusive 23rd midday
Infected the first person on evening 23rd.
Did another PCR as DP had a nasty cough/chest infection on 24th and I insisted he redo it as it was too suspicious - at this point he was certain inconclusive = negative.
Infected the other two on 25th when the results came through as positive - despite knowing this they turned up anyway for a Covid Christmas party (prevaccine at that point, so they figured getting it all together was better 😅).
Hope that helps. I know it's hard but try not to worry ❤️
This variant is definitely a lot milder, it's affecting tissue higher up in the lungs, not attacking the tissues in the nose, is a lot more like a common cold and with double vaccination no one has died, with boosters, the infection chance is also really tiny. We also have better treatments for Covid now, very few people who are in good health and catching it are even going into hospital.
