Exposed to covid, chances I have it?

[studioapartment]

Hi, can someone explain to me the risks of me having covid?

I live alone, and so I am part of a bubble household with a good friend who house shares with two others. I saw my friend on Tuesday, Wednesday, Thursday, Friday. On Friday morning she took a test as was due to undergo an operation... it came back positive! (Friday 11th)

On the Monday night, two of them went out for dinner in a small restaurant that wasn’t socially distancing. They then caught public transit home. One of these friends tested positive for covid in April, and my close friend was ill at the time so assumed she’s caught it off her flatmate (a doctor).

I took an antibody test through work in October and had antibodies. I know that it was in March when I had all the symptoms is when I had covid but didn’t know at the time. So I may or may not have some level of immunity, depending on if they went since October.

I took a test on Saturday-Negative. Both of the flatmates in my friend’s initial household also tested Negative.

I have two lateral flow tests through work. I was going to use them before going to stay with relatives on the 23rd for Christmas.

What are the chances I have covid and it’s not developed yet? If both lateral flow tests come back negative, shall I go to my relatives house or could I still have covid?

The key info that is missing is what you did you n what environment on Tues Weds Thurs Fri.

If you need to isolate as a result of that contact you should act as though you have it and not put others at risk, irrespective of test results.

You shouldn't be at work for example.

Oh no of course- I am isolating for the 10 days since last contact with the case!

Oh ok. If ten days since last contact you will be fine by Christmas according to the new rules. Hopefully covid got the memo that the government want it to stop being infectious by day 11 now!!

If you had antibodies they don't just go and you have nothing, your body would react very quickly to Covid should you be exposed again as you have an immune memory response that can produce antibodies again(strain:mutation etc permitting) quickly

A person is contagious 2 - 3 days before symptoms show - has your friend had symptoms show yet? This may be scuppers off they're asymptomatic however.
