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. lytic, because the virus causes a respiratory illness
B. lysogenic, because the virus is a coronavirus
C. lytic, because of the quick onset of symptoms after infection
D. lysogenic, because the virus primarily affects older people
