A 'how did we catch it' conundrum?

[ApolloandDaphne]

This is like one of those mind bender puzzles

3 couples met and had dinner at someone house on Saturday. All tested negative on LFT then.

One member of each couple tested positive on Thursday. The second member of one couple tested positive on Saturday. The other two have been testing negative this week.

None of us had been around each other before Saturday.

So who was it that passed on Covid initially?

Can it be carried and transmitted by someone but not show up on tests?

The two who didn't get it have both been working outside the hoe , one in an office and one in a school, so would be most, likely to have been in contact with it.

While you are pondering this maybe you can work out that only my husband out of the 4 of us had covid 2 weeks ago?

Our whole family had covid. Youngest DD had a positive PCR so we knew beyond doubt. However LFTs continued to remain negative until 72 hours past symptoms. Also the NHS blue/white LFTs never showed positive. Even though we 100% had it. I thought all this was known since December. LFTs are not fool proof. Only FlowFlex showed positive for us, not the blue/white ones.

This just demonstrates how futile testing is. Sensible decision to stop providing these tests for free!

Are the flow flex the nose only ones and the blue/white ones the nose/throat ones?

The numbers are so ridiculously high at the moment, it's possible that you all got it from different things and not necessarily the dinner party.

I.e someone could have got it Saturday in the supermarket. Someone else got it on a train Monday morning.

It's just a coincidence you had positive lfts on Thursday?

It is possibly pure coincidence.

DS started symptoms Thursday, negative LFT Thursday and Friday, negative PCR Friday but he’s definitely positive today on LFT.
If he can be be negative on PCR with symptoms then someone asymptomatic can definitely be negative on LFT.

My dad has quite obviously had Covid. But has tested negative on LFT all the time

DH and DS have had the same symptoms and also tested negative

I've no symptoms and not tested at all

@ApolloandDaphne - yes that's correct. The FlowFlex are also short sticks.

My DD takes a taxi to school. The lady who drives her called me to say she had covid symptoms but was testing negative so wasn't sure what to do. I asked her if she could find a FlowFlex and test with it. No surprise - she was positive.
