SARS-CoV does not act like the other coronaviruses. It's classification is debated by researchers but some put it in group 2. 
Phase I of initial showing of SARS-CoV symptoms :
Fever > 38°C
Phase 2 (3 - 7 days after initial symptoms) Characterized by cough and shortness of breath. Hypoxia can develop in individuals and relative lymphopenia and neutropenia is possible. 
Some patients showed a biphasic course, with apparent recovery followed by worsening of the clinical condition. Mortality was highest in the elderly and lowest in the younger population, and co-existing illness worsened morbidity and mortality. Upwards of 10 - 20% of cases needed ventilation.
