Concept #1: Acute vs. Persistent Viral Infections

Practice: An infection in which the virus is continually present in the body is referred to as:

Practice: Diseases of short duration frequently followed by long-term immunity are referred to as:

Practice: Which of the following viral infections is considered an acute infection? (Answer choices show the name of the virus and the time it remains present in the body).

Concept #2: Acute vs. Persistent Viral Infections

Practice: Which of the following statements about acute viral infections is false?

Practice: A vaccine to a virus allows the body to be exposed to the virus and not get sick. This allows the body to recognize the virus and better fight the virus if the person does become infected. How would a vaccine help someone deal with a virus which causes an acute infection?

Concept #3: Acute vs. Persistent Viral Infections

Practice: Varicella is an acute infectious disease commonly known as chicken pox. This disease is caused by a DNA virus that causes a moderate to severe body rash that stays dormant in the body after the rash. The virus can be reactivated years or decades later creating a rash known as shingles. What type of infection is occurring when the virus is dormant in the body for years?
