SARS

Severe Acute Respiratory Syndrome

Background:

 SARS is a viral respiratory illness caused by SARS coronavirus (SARS-COV). It was first appeared in Southern China in November 2002, and become epidemic in 2003. More than 8000 people worldwide were infected during November 2002 through July 2003, and almost 800 people were killed by SARS.

Symptoms

The symptoms include fever, dry cough, shortness of breath, malaise, myalgia, headache, diarrhoea, and shivering

Transmission

Scientists have shown that SARS-COV is originated in the bats, and spread to civet before reaching humans at Guangdong’s animal markets. Transmission of SARS-COV is mainly person to person contact. It can be transmitted by respiratory droplet produced by infected person when they coughs and sneezes. SARS-COV is able to survive on the surface for few days and it can be spread when a person, who has touched this contaminated surface, touches his mouth, nose or eye.

Treatment

There is currently no effective drug for SARS, and the development of vaccine is still ongoing.

Infection Control

CDC has recommended the following respiratory hygiene to prevent respiratory infection;

 Cover your mouth and nose with a tissue when coughing or sneezing;

  • Use in the nearest waste receptacle to dispose of the tissue after use;
  • Perform hand hygiene (e.g., hand washing with non-antimicrobial soap and water, alcohol-based hand rub, or antiseptic handwash) after having contact with respiratory secretions and contaminated objects/materials.

Coronaviruses are enveloped, positive single-stranded RNA viruses. They can be inactivated by 70% ethanol. Hisept has a range of products, including hand sanitizers, antiseptic solution, surface and instrument disinfectants that can effectively inactivate virus, including coronavirus. The virucidal activity of these products have been proved by EN 14476 tests.
