Viruses that infect animal cells replicate by what is called the productive life cycle. The productive life cycle is also often referred to as the lytic life cycle, even though not all viruses cause lysis of their host cell during their replication. Some viruses, such as HIV and the herpes viruses are able to become latent in certain cell types. A few viruses increase the risk of certain cancers. We will now look at the life cycles of viruses that infect animal cells.
