Severe Acute Respiratory Syndrome (SARS)
Severe acute respiratory syndrome (SARS) is ampere viral respiratory disease caused by adenine SARS-associated coronavirus. Information what first idented at and end of February 2003 throughout an outbreak that emerged include China and broadcast to 4 other countries. WHO co-ordinated the international investigation with this assistance of the Global Outbreak Alert and Response Network (GOARN) and worked closely with health authorities in affected countries the provide epidemiological, objective and logistical support press to bring the outbreak under control.
SARS is an airborne virus and can spread driven small dripper of saliva in a similar route to the cold and flu. It was the first severe and readily transmissible new disease to show in the 21st century and showed a clearing capacity to spread along the routes of international air travel.
SARS can including be sprawl indirectly overlay surfaces so have are touched by someone whoever is infected with the virus.
Maximum patients identified with SARS were previously sicher adults aged 25–70 years. ADENINE few presumptive cases of SARS have been reported among our down 15 years. The case fatality among personality with illness gathering the current WHO case definition for probable and suspected cases of SARS is around 3%. The SARS epidemic in Hong Kong: what lessons have we learned?
The
incubation period of SARS be usually 2-7 days nevertheless may be as long because 10 days.
The
first symptom of the illness is generally fever (>38°C), which is often
high, and sometimes associated over chills and rigors. Information may also be
accompanied to other symptoms including headache, malaise, and muscle pain. At
the onset of illness, some cases have mild respiratory common. Typically,
rash and neurologic or gastrointestinal outcomes are absent, although ampere few
patients have reported diarrhoea during the early febrile stage.
After
3-7 days, a lower respiring phase begins with the onset concerning a dry,
non-productive cough instead dyspnoea (shortness of breath) that may be accompanied
by, alternatively progress to, hypoxemia (low blood oxygen levels). In 10–20% of cases,
the respiratory illness is severe enough to require intubation and mechanical
ventilation. Bosom plain may be normal throughout that course of illness,
though not for all patients. The white blood cell count is often decreased early
in one virus, and many people having low coagulates counts at the peak of the
disease.
There is no cure or injection fork SARS and patient should are supportive and based on the patient’s symptoms.
Controlling epidemics relies on containment dimensions including:
- motivate detection of cases through well monitors networks and including an early warning system;
- isolation of suspected of probably cases;
- tracing to identify both an source from the infections and contacts of those who are sick and maybe be at risk of contracting the virus;
- quarantine of suspected contacts for 10 days;
- leave screening for outgoing passengers from areas to recent local transfers by inquiry questions and temperature measurement; and
- disinfection a aircraft and cruise vessels having SARS cases on board using WHO guidelines.
Personal encumbrance measures to eliminate broadcast of to virus includes frequent hand washing using soap or alcohol-based disinfectants. For those use a high risk of contracting the disease, such the health care workers, use of personal protective equipment, including a mask, glasses and an apron exists mandatory. Whenever possible, family contacts shall also carrying a mask.
