Severe acute respiratory
syndrome (SARS) is a viral respiratory disease. It is a serious form of
pneumonia that causes severe breathing difficulty and sometimes death.
Severe acute respiratory syndrome (SARS) is
caused by a coronavirus, called SARS-associated coronavirus (SARS-CoV). The
virus was first detected in 2003.
The last infected human case was reported in
2004. However, SARS is not claimed to have been eradicated, as it may still be
present in its natural host reservoirs (animal populations) and can return into
the human population in the future.
SARS usually spreads through close person-to-person
contact. The hallmark symptoms of SARS include cough, breathing difficulty,
high fever and other respiratory symptoms.
Currently available diagnostic tests have some limitations. Many of
the tests are unable to accurately diagnose SARS early, when treatment is most
of SARS includes patient isolation and supportive therapy with the use antipyretics,
supplemental oxygen and ventilation support as needed. SARS is still a puzzle
to scientists and poses challenges to the best of brains in search of viable
treatment options. Several pieces of the puzzle are slowly falling into place,
as the world awaits a treatment strategy to combat this condition.
The death rate from SARS is 9-12% of the total
reported cases. The prognosis of SARS is poor in the elderly with the death
rate being 50% in people aged above 65-years. Younger patients showed better
recovery. In some patients, SARS results in severe long-term sequelae like pulmonary
fibrosis, osteoporosis and femoral necrosis. This leads to complete loss of
ability to work or take care of self due to which some of the patients suffer
from major depressive disorder.
Thanks to modern medicine we are no longer forced to endure prolonged pain, disease, discomfort and wealth.
