Viral inhibitors are substances that are designed to prevent the replication and spread of viruses within the body. These inhibitors can target various stages of the viral life cycle, such as attachment to host cells, penetration into cells, replication of viral genetic material, assembly of new viral particles, and release of viruses from infected cells. They can be developed as antiviral drugs or vaccines to treat or prevent viral infections. Viral inhibitors play a crucial role in the field of virology and are constantly being researched and developed to combat the spread of viral diseases.
