Don't understand how we are all negative

[kissmelittleass]

My teenage ds tested positive on the 18/2 ( not in uk) myself Dh and other three children were told to go for a test the following day, results all negative.
Nine days later ( Saturday gone) we all had another test and results again were all negative!
We are now allowed out from tomorrow as is my son who tested positive, what I don't understand is how we were all negative when positive ds shares a room with his sibling.
My son made me a cup of tea the night before he got symptoms, I also gave him a hair trim same night so lots of contact.
He was also playing around with his younger sister night before, anyone he had been in contact with through work also tested negative?
Obviously delighted we were all negative but don't understand how when this virus is so contagious we all dodged it? Anyone have any idea?!

Some great explanations/theories here but basically we know nothing about this virus it's a 50/50 it seems 🤷‍♀️
My son was told he probably contracted the virus about three days before his onset of symptoms and was tested on first day of symptoms, the rest of the household ( five of us) were tested the following day therefore according to what my son was told we were tested on day four of him contracting the virus and I'm assuming if the rest of us were a symptomatic then we would of received a positive result and not a negative result that we all got !?

My partner was positive and I had two negative tests and we had been sexually active the day before he tested positive.

I don't understand this timeframe. If he tested positive on day 3 (nobody can know this was day 3 with certainty unless he was a hermit by the way), then it would take on average 3-7 days got him to infect any of you and can take up to 14 days. Any of you could also have been infected before him and passed it on. Why were you all getting a test the day after he did, that makes no sense?

@MRex We are not in the UK different advice/regulations as I've previously already stated!!! We were tested the day after him because that's what we were told to do by track and trace and then you get tested again ten days after the positive person's first onset of symptoms.
He was told he probably caught the virus three days before he developed symptoms!!! but 3-5 days before symptoms is the normal, but what do I know 🤷‍♀️I'm only repeating what track and trace told us and also our GP who called us! Obviously different to the UK

It's the same virus, the infection timeframe from all the research is 3-14 days exposure, most common is 3-5 days. That isn't affected by what country you're in unless you think there's a different variant changing timeframes. The point is that you can't say for sure he didn't infect you based on a test only 1 day after he got symptoms, nor does that tell you if any of you had it before and recovered. Have you had the 10 day test results yet?

Could be false positive for ds.

Less likely to be false negative for you as it’s all of you.

Or could be that you have built up immunity of one kind or another (either antibodies or T cells)

More common than you think. I tested positive on Xmas Eve. I was not ill as such and tested only because I lost taste and smell. I did not distance from dh or the dc’s during our 10 day isolation. I cooked Xmas dinner and interacted with the family as normal, played board games watched tv together, slept in same bed as dh etc. None of them got any symptoms. DH just did an antibody test which came back negative so very unlikely he caught it.

@MRex yes we did we were all negative

Ah good, unlikely any of you caught it then. Does your son speak quite quietly?

I think there is a statistic which says only 10% of those whom are positive, are responsible for 90% of further spread. The thing is, they do not yet know how to identify these "superspreaders", I think they are doing research on that now.

I read somewhere that one country (can’t remember) is trialling testing immediate contacts of the positive case, if none are positive then they aren’t a super spreader and they can leave it at that.

If main contacts are positive then they isolate further contacts and go harder for this person as they may be a super spreader. Not sure if I’m remembering this 100% correctly. The key for long term management of this virus surely is to identify these super spreaders very quickly.

@MRex He wouldn't be a loud talker tbh he's certainly a quieter talker than my daughter!

@kissmelittleass it seems to work randomly! My neighbour got it over Christmas, lives with her DH and x3 kids two of whom are adults. None of them got it yet her son in law who had visited around the time she got it and lived in a different household caught it from her! He didn’t give it to his wife or children.

We have 7 in our house, well 8 as my mum in our bubble, she is extremely vunreable.

I got it early last year, no one got it.
My dd got it just before xmas, again no ine else got it.

My sister got it, went through her whole house.

My cousin got it shared a bed with her dh he never got it.

No rhyme ir reasson

I shared a bed with my husband, cuddled my children and no one caught covid off me.
