Viral inactivation renders viruses unable to infect. Many viruses contain lipid or protein coats that can be inactivated by chemical alteration.

[ 6 ] Viruses use the host's cells to replicate and this makes it difficult to find targets for the drug that would interfere with the virus without also harming the host organism's cells.
