Human Papilloma Virus (HPV) infection is considered an epidemic and can lead to lethal cancers. It is assessed that the risk of sexually active women to be infected sometime in their lifetime is nearly 80%. Prevalence of cervical cancer and high mortality rates, especially in developing countries, are alarming and require immediate attention.
What co-factors have been identified to have roles in the progression of human papilloma virus infection to cervical cancer?
HPV viruses have a distinct capability to evade confrontation with the human immune system? Give three basic virus properties responsible for this capability.
What is the role of vaccination in the management of HPV infections?

In your own words, provide a short summary of the HIV replication cycle. 5. Why is reverse transcriptase an important enzyme in the replication cycle of HIV? 6. In the chapter about enzymes, we have discussed how drugs are basically inhibitors. There are currently a multitude of Antiretroviral therapy (ART or ARV) options available to people living with HIV (PLHIV) so that the viral replication is suppressed and does not progress to AIDS. What do you think these drugs target? Discuss briefly. 7. SARS-CoV-2, the virus that causes CoVid-19, belongs to the Coronaviridae family. Viruses under this family have a genome made of single-stranded positive-sense RNA. Is this similar to the viral genome of HIV?
