Patient's Query

Hello doctor,

I tested positive on a rapid antigen test one month back and negative by day nine. I need to retake a rapid antigen test to return to the western country. Can I safely assume I will continue to show up as negative? I am worried that the rapid antigen test will somehow pick up the COVID-19 that I had over a month ago, even though I tested negative by day nine. Can it reappear?

Hello,

Welcome to icliniq.com.

You have already tested negative, and the chances of again becoming positive are negligible. Let us hope for the best.

Patient's Query

Hello doctor,

So, what level of immunity do I have? I was vaccinated thrice and had a breakthrough infection. With the omicron infection positive, can I assume that I am immune for the next few weeks? I am worried about suddenly testing positive as I am surrounded by many people.

Answered by Dr. J. N. Naidu

Hello,

Welcome back to icliniq.com.

Indeed you are well protected with good antibody levels. Generally, only the elderly are vaccinated three times as antibody production is low. You have taken extra care to get three doses, so the chances of testing positive are almost nil. As you are so worried, I suggest you try to keep away from those who have fever and cough. Use a mask when new people are around you. Immunity should last at least a year and not weeks.

I wish you the very best.

Same symptoms don't mean you have the same problem. Consult a doctor now!
