Is there any monitoring of nucleic acid sealing?

Yes.

If nucleic acid testing is required, it means there is a risk of infection. There is a risk until the test results are available. In order to better control the epidemic, surveillance is installed.

Nucleic acid is the general term for deoxyribonucleic acid DNA and ribonucleic acid RNA. It is a biological macromolecular compound polymerized from many nucleotide monomers and is one of the most basic substances of life.
