What is the incubation period for SARS?
The time between getting infected and the start of symptoms (the incubation period) is about two to seven days but occasionally has been up to 14 days.
What are risk factors for SARS?
SARS-CoV can infect a person regardless of their health status or age group. However, it was clear that some people were at increased risk during the 2002-2003 outbreak. This included people over the age of 50 (some reported mortality rates of about 50%), pregnant women, and those with underlying diabetes, heart disease, or liver disease. A major risk factor is simply close association with any person infected with SARS-CoV since the virus can be spread through droplets sprayed into the air by coughing, sneezing, or even talking.
Other risk factors include the following:
- Recent travel to mainland China, Hong Kong, or Taiwan or close contact with ill people with a history of recent travel to these areas
- Employment in an occupation at risk for SARS-CoV exposure, including a health-care worker with direct contact with a patient having SARS-CoV, or a worker in a laboratory that contains live SARS-CoV
- Relationship with a cluster of cases of atypical pneumonia without an alternative diagnosis
