This causes the host. information highlighted below and resubmit the form. This explains why a virus that causes illness in a cat may not affect a human. everyone has it at sometime. There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some of these drugs stop DNA synthesis, preventing the virus from replicating. The non-peer-reviewed study found that the two viruses have similar viability in the environment, however, the study determined the novel coronavirus could survive up to three days on stainless steel and plastic surfaces. Antivirals are also available to treat infection with HSV, hepatitis B, hepatitis C, influenza, shingles, and chickenpox. Viruses are curious things.
