Answer:
The main difference between latent and virulent viruses is that latent viruses remain dormant or inactive inside the host cell, while virulent viruses actively replicate and cause disease.
Latent viruses can remain inside the host cell for extended periods without causing any symptoms. These viruses do not actively replicate, but instead, integrate their genetic material into the DNA of the host cell. Examples of latent viruses include the herpes simplex virus, which can cause cold sores and genital herpes, and the varicella-zoster virus, which causes chickenpox and can later reactivate to cause shingles.
Virulent viruses, on the other hand, actively replicate and cause disease in the host. They can cause symptoms ranging from mild to severe and can lead to the death of the host. Examples of virulent viruses include the flu virus, HIV, and Ebola virus. These viruses actively replicate within the host, causing damage to the host's cells and tissues and triggering an immune response that can further damage the host's body.
