Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms including a high fever, headaches, and body aches typically occur two to
seven days after infection by the virus. SARS is more serious in elderly patients. This
information suggests that the reproductive cycle of the SARS virus is -
A. lysogenic, because the virus is a coronavirus.
B. lytic, because the virus causes respiratory illness
C. lysogenic, because the virus primarily affects older people.
D. lytic, because of the quick onset of symptoms after infection.
