I'm a bit concerned after getting my covid test results. When I took the test, I had a cough, and my CT value was 21. Now, I don't have any cold or cough symptoms anymore. Is this something I should be worried about? What do you think?

A CT value of 21 indicates a high viral load at the time of testing. Since you no longer have cold or cough symptoms, it is a good sign that your body has likely fought off the infection. However, it is still important to monitor your symptoms and follow up with your healthcare provider for further guidance. In the meantime, you can consider taking a course of antibiotics like Azithromycin 500mg once daily for 5 days to prevent any secondary bacterial infections.
