SARS

An overview of the and its significance

The severe acute respiratory syndrome (SARS )is a viral infection characterized by often high fever , malaise , and a dry cough with dyspnea that can lead to hypoxemia and death . It is caused by a new form of the coronavirus never before seen in humans . Coronaviruses are a group of viruses that have distinctive crown-like spikes . The mainly spread by close person-to-person contact . After two to seven days , SARS patients may develop a dry cough with most developing pneumonia

The risks factor of having

SARS are close contact within the previous 10 days with a probable case of SARS , recent travel within the previous 10 days to a reported affected area . Its main symptoms of SARS are high fever , combined with a dry cough , shortness of breath , or breathing difficulties .There are three possible diagnostic test are done . The blood sample is being tested if there is an infection when it was first recognized and again 3 weeks later . With regards to the treatment of SARS , there is no proven effective treatment for SARS . There have been different treatment approaches used throughout the affected countries The WHO and the CDC have established a number of guidelines aimed at stopping transmission of the disease

Mechanism behind the disease and the physiological processes disrupted by the disease

The illness usually begins with a high fever (temperature greater than 100 .4 degrees F . The fever is sometimes associated with chills or other symptoms , including a headache , a general feeling of discomfort , and body aches

Some people also experience mild respiratory symptoms at the outset Approximately 10-20 percent of patients have diarrhea . About 3 to 7 days later , dry cough and difficulty breathing may develop . Most people recover within 1 to 2 weeks . However , about 10 to 20 develop severe difficulty breathing , resulting in insufficient oxygen in the blood worldwide , about half of these people need assistance with breathing . In addition to these symptoms , SARS may be associated with other symptoms including : loss of appetite , malaise , confusion , rash and diarrhea Severe respiratory illness may occur before abnormalities are noted on chest X-ray . At the outset , the illness may be very mild

The signs and symptoms in young infants and children may not follow the exact pattern that is seen in adults . Consequently , doctors are on the lookout for a typical forms of presentation in very young infants . In adult patients with SARS , there is usually a fever , which may be accompanied by chills and other symptoms such as headache and general body aches . In the early stages of the illness , patients may have these nonspecific symptoms (headaches and general body aches

A novel coronavirus , severe acute respiratory syndrome coronavirus (SARS-CoV , has recently been identified as the causative agent of severe acute respiratory syndrome (SARS . SARS-CoV appears similar to other Coronaviruses in both vision structure and genome organization . It is known for other Coronaviruses that the spike (S ) glycoprotein is required for both viral attachment to permissive...
