Answers:
Severe acute respiratory syndrome or SARS is a respiratory disease in humans which is caused by the SARS coronavirus.
Initial symptoms are flu-like and may include: fever, myalgia, lethargy, gastrointestinal symptoms, cough, sore throat and other non-specific symptoms. The only symptom that is common to all patients appears to be a fever above 38 °C (100.4 °F). Shortness of breath may occur later. Symptoms usually appear 2–10 days following exposure, but up to 13 days has been reported. In most cases symptoms appear within 2–3 days. About 10–20% of cases require mechanical ventilation.
SARS may be suspected in a patient who has:
Any of the symptoms including a fever of 38 °C (100.4 °F) or more AND
Either a history of
Contact (sexual or casual) with someone with a diagnosis of SARS within the last 10 days OR
Travel to any of the regions identified by the WHO as areas with recent local transmission of SARS (affected regions as of 10 May 2003 were parts of China, Hong Kong, Singapore and the province of Ontario, Canada).
A probable case of SARS has the above findings plus positive chest x-ray findings of atypical pneumonia or respiratory distress syndrome.
Antibiotics are ineffective. Treatment of SARS so far has been largely supportive with antipyretics, supplemental oxygen and ventilatory support as needed.
There was initially anecdotal support for steroids and the antiviral drug ribavirin, but no published evidence has supported this therapy. Many clinicians now suspect that ribavirin is detrimental.
In December 2004 it was reported that Chinese researchers had produced a SARS vaccine. It has been tested on a group of 36 volunteers, 24 of whom developed antibodies against the virus.
A 2006 systematic review of all the studies done on the 2003 SARS epidemic found no evidence that antivirals, steroids or other therapies helped patients. A few suggested they caused harm
