X ray has shown poor sensitivity on the contrary, CT scan has shown remarkable sensitivity during the pandemic and has helped healthcare professionals detect and medicate patients suffering from Covid 19

My daughter is 1 year old, and my recent test report came positive. How should I take care of my daughter in this situation to keep her safe?

Answered by Apollo Doctors

My report came negative after 14 days of isolation. I would like to know if any precautions need to be taken and for how long, as I have a 3 year old son. Also, my mother in law and father in law are at home. It has been a total of 17 days now. Is any medication required post COVID? When will smell or taste resume? I had a mild infection with no fever or cold before testing. I am also experiencing leg pain, dryness in throat and nose, and weakness post COVID. Am I still infectious? Blood tests including D dimer were fine and oxygen level is 96+. Please suggest?

Answered by Apollo Doctors

On day 6 after infection, I did an RTPCR test. Today is day 10, and my report has come back with a Ct value of 22/25. I do not have any significant symptoms now, and my sense of smell and taste are normal. Should I be concerned about this Ct value?
