I definitely don't think it should happen until the antibodies test is available. I have what's in all probability a moderate form of COVID-19 (it doesn't feel moderate but I haven't had to go into hospital and hopefully won't now) and I could only have caught it from my DD2 (8), who had had been really unwell with what had been diagnosed as a 'respiratory virus', high temperature, chest pain, headaches, and aches and pains all over. Back then, they were only asking whether people had been to 'infected areas overseas' or been in 'direct contact with a confirmed case'
No cough or not much so it never occurred to me that it might be different from the nasty virus I was recovering from (a normal winter virus).
5 days later, I ended up with a horrendous cough., and that was two and a half weeks ago. I've had some very scary moments, with bad chest pain, really horrible coughing fits and times when I've been almost unable to breathe due to a build up up sputum which the coughing doesn't get rid of, I've had to forcibly clear it, puking or with decongestants. Now I can't keep food down.
I haven't even been tested, so I don't know for sure that it's COVID-18 though I can't think what else it could be. I've had good support from NHS 111 and our surgery, however. My DH once called 999 when it looked like I was losing consciousness. He was called back by paramedics who talked him through ways to help me breathe again.
I wouldn't want my DDs back in school until I know that I'm not at risk from this, I wouldn't want the same thing happening again!
