Why it is so important for the body to be protected against viral pathogens?

Certain viral pathogens can lead to death. Viruses like Human Immunodeficiency Viruses (HIV) are not considered lethal on their own but lower your body's ability to fight infections, and over time cause Acquired Immunodeficiency Syndrome (AIDS). If infected by this virus you could be killed by the common cold. That is why it is important to be protected against viral pathogens.
