Native speakers would say "Disaster! I've got Covid!"
How [STRIKE]to[/STRIKE] does one say [STRIKE]it[/STRIKE] formally that one got Covid?
We don't start questions with "How to".
I see people saying "I am tested positive".
If they're saying that, they're not native speakers. You should hear "I have tested positive [for Covid]" or "I tested positive [for Covid]".
I want to say it in the past tense.
Now the person [STRIKE]is[/STRIKE] has recovered.
I am searching for a [STRIKE]better[/STRIKE] good alternative [STRIKE]than[/STRIKE] to "I was tested positive".
One needs to send an email to his boss explaining why he was not able to finish his work on time. Will 'I had tested positive work'?Why do you need to say it "formally"?
I see no need for the past perfect.
Someone has already recovered and no longer Covid positive. I meant it in this context.
There is still no need for a past perfect unless you are relating this to a later past event.
I am not sure what you mean by that. Who is "Someone"?
I am talking in general terms and using third person.
One needs to send an email to his boss explaining why he was not able to finish his work on time. Will 'I had tested positive work'?
You are correct.
Do you mean something like "I (your "someone") couldn't finish the work in time because I had tested positive for COVID-19 (and I had been hospitalized)"?
