I recently tested positive for COVID 19 three days ago, and my report shows a CT value of 19.2. I am almost asymptomatic, with only a slight dry cough and occasional mild headache, but no fever. What does this CT value mean, and when should I get tested again to check if I am negative?

A CT value of 19.2 indicates a high viral load. Despite being mostly asymptomatic, continue strict isolation and monitor symptoms. There is no need to retest immediately unless required for travel or discharge criteria.

I am 5 months pregnant. Today, my husband and I got RTPCR tests done, my report is negative, and his is positive. I am experiencing symptoms like loss of taste and smell. Should I repeat the test? I also had a previous rapid test, which was negative. What should I do next?

Answered by Apollo Doctors

I lost my sense of smell and taste today. I had a fever with body aches starting on the 18th, but I no longer have a fever. I am waiting for my COVID test report. In the meantime, I want to start some medication. Could someone please advise what I should do?

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?
