The boss said the nucleic acid test was negative. How should I reply?

Make it clear that you can reply to the boss "Thank you for your concern. My nucleic acid test results are negative.

"Nucleic acid detection is a method to detect COVID-19, and negative means no infection.

Your reply can tell the boss that you are not infected with COVID-19 at present.

In addition to nucleic acid testing, you can also pay attention to maintaining protective measures, such as wearing a mask and washing your hands frequently to avoid contact with the environment and people who may be infected with the virus.

This can protect the health and safety of yourself and others.
