Signs and symptoms of SARS include flu-like nonspecific symptoms including fever, chills, and malaise. Symptoms develop within a week of infection with the virus. Infected people become ill within a week of exposure. The next associated symptoms include signs and symptoms of atypical pneumonia with respiratory distress, shortness of breath and dry cough.
