Via interferons. Virally infected cells produce and release small proteins called interferons, which play a role in immune protection against viruses. Interferons prevent replication of viruses, by directly interfering with their ability to replicate within an infected cell.
Can you have a chronic viral infection?
Varicella-zoster virus, measles virus, HIV-1, and human cytomegalovirus are examples of viruses that cause typical persistent infections. A chronic infection is a type of persistent infection that is eventually cleared, while latent or slow infections last the life of the host.

Egress (Release) The last stage of viral replication is the release of the new virions produced in the host organism, where they are able to infect adjacent cells and repeat the replication cycle.
Why do viral infections make you tired?
The authors of an earlier study suggest that the symptom of fatigue after a viral infection is due to inflammation in the brain. Viruses cause the immune system to respond and attack them. This response causes stress and inflammation in the body.
