Summary

Severe acute respiratory syndrome (SARS) is a novel febrile illness linked to a new coronavirus, spreading globally with significant mortality. Current management focuses on supportive care and infection control due to a lack of specific therapies.

Area of Science:

* Infectious Diseases
* Virology
* Public Health

Background:

* Severe acute respiratory syndrome (SARS) emerged in China in 2002.
* The outbreak rapidly spread internationally, causing over 8000 cases and 750 deaths.
* A novel coronavirus, SARS-associated coronavirus (SARS-CoV), was identified as the causative agent.

Purpose of the Study:

* To summarize current knowledge on SARS epidemiology.
* To detail clinical features and transmission modes.
* To outline effective infection control strategies.

Main Methods:

* Review of existing literature and epidemiological data.
* Analysis of clinical case reports.
* Assessment of transmission dynamics.

Main Results:

* SARS-CoV is the etiologic agent of SARS.
* Transmission primarily occurs via large droplet spread.
* The disease presents with febrile respiratory illness and has a notable mortality rate.

Conclusions:

* No specific antiviral therapy is currently available for SARS.
* Supportive care is the cornerstone of patient management.
* Stringent infection control measures are crucial to contain SARS outbreaks.
