Severe acute respiratory syndrome coronavirus (SARS-CoV or SARS-CoV-1) is a strain of virus that causes severe acute respiratory syndrome (SARS). It is an enveloped, positive-sense, single-stranded RNA virus which infects the epithelial cells within the lungs. The virus enters the host cell by binding to angiotensin-converting enzyme 2.
- Signs and symptoms
Severe acute respiratory syndrome is a viral respiratory disease of zoonotic origin caused by severe acute respiratory syndrome coronavirus, the first identified strain of the SARS coronavirus species severe acute respiratory syndrome–related coronavirus. The syndrome caused the 2002–2004 SARS outbreak. Around late 2017, Chinese scientists traced the virus through the intermediary of Asian palm civets to cave-dwelling horseshoe bats in Xiyang Yi Ethnic Township, Yunnan. SARS was a...
SARS produces flu-like symptoms and may include fever, muscle pain, lethargy, cough, sore throat, and other nonspecific symptoms. The only symptom common to all patients appears to be a fever above 38 °C. SARS may eventually lead to shortness of breath and pneumonia; either direct viral pneumonia or secondary bacterial pneumonia. The average incubation period for SARS is 4–6 days, although rarely it could be as short as 1 day or as long as 14 days.
The primary route of transmission for SARS-CoV is contact of the mucous membranes with respiratory droplets or fomites. While diarrhea is common in people with SARS, the fecal–oral route does not appear to be a common mode of transmission. The basic reproduction number of SARS-CoV, R0, ranges from 2 to 4 depending on different analyses. Control measures introduced in April 2003 reduced the R to 0.4.
SARS-CoV may be suspected in a patient who has: 1. Any of the symptoms, including a fever of 38 °C or higher, and 2. Either a history of: Contact with someone with a diagnosis of SARS within the last 10 days or Travel to any of the regions identified by the World Health Organization as areas with recent local transmission of SARS. 3. Clinical Criteria of Sars-Cov Diagnosis Early illness: equal to or more than 2 of the following: chills, rigors, myalgia, diarrhea, sore throat Mild-to ...
There is no vaccine for SARS, although immunologist Anthony Fauci mentioned that the CDC developed one and placed it in the US national stockpile. That vaccine, however, is a prototype and not field-ready as of March 2020. Clinical isolation and quarantine remain the most effective means to prevent the spread of SARS. Other preventive measures include: 1. Hand-washing with soap and water, or use of alcohol-based hand sanitizer 2. Disinfection of surfaces of fomites to remove viruses 3. Avoiding
As SARS is a viral disease, antibiotics do not have direct effect but may be used against bacterial secondary infection. Treatment of SARS is mainly supportive with antipyretics, supplemental oxygen and mechanical ventilation as needed. While Ribavirin is commonly used to treat SARS, there seems to have little to no effect on SARS-CoV, and no impact on patient's outcomes. There is currently no proven antiviral therapy. Tested substances, include ribavirin, lopinavir, ritonavir, type I interferon

SARS coronavirus 2 (SARS-CoV-2) is a positive-sense, single-stranded RNA coronavirus which causes the disease COVID-19. It used to be known as 2019 novel coronavirus (2019-nCoV) by the World Health Organization (WHO). The virus started the 2019–20 coronavirus outbreak. The first suspected cases were reported to the WHO on December 31, 2019.

Severe acute respiratory syndrome (SARS) was an atypical pneumonia. It started in November 2002 in Guangdong Province, in the city of Foshan, of the People's Republic of China. The disease was caused by the SARS coronavirus (SARS CoV), a new coronavirus. It was also a part-time STD, it can be spread through both sexual and casual contact.
