Answers
Answer:
Severe acute respiratory syndrome-related coronavirus is a species of coronavirus that infects humans, bats and certain other mammals. It is an enveloped positive-sense single-stranded RNA virus that enters its host cell by binding to the angiotensin-converting enzyme 2 receptor.

Answer:
Severe acute respiratory syndrome, or SARS, is a contagious and potentially fatal respiratory illness.
SARS is caused by a type of coronavirus, called SARS-associated coronavirus (SARS-CoV). It is related to SARS-CoV-2, the virus that causes COVID-19 infection.
SARS first appeared in China in November 2002 and was identified in February 2003. It spread to over 24 countries before it was contained.
From November 2002 to July 2003, there were 8,098 cases worldwide and 774 deaths.
The United States (U.S.) saw eight laboratory-confirmed cases and no fatalities. All eight people had traveled to areas affected by SARS.
Strong levels of global cooperation ensured that the threat of SARS was dealt with swiftly, and the spread of the disease was effectively contained.
Since May 2004, no new cases have been reported.
What is SARS?
SARS is extremely contagious, and many wore face masks during the last outbreak in 2002.
The SARS coronavirus (SARS-CoV) causes SARS. A coronavirus is a common form of virus that typically causes upper-respiratory tract illnesses. The common cold results from a kind of coronavirus.
Six different kinds of coronavirus are known to infect humans. Four of these are common, and most people will experience at least one of them at some time in their life.
The two other types cause SARS and Middle East Respiratory Syndrome (MERS). These are less common but far more deadly.
Before SARS appeared, coronaviruses had not been particularly dangerous to humans, but they had been known to cause severe diseases in animals.
As a result, scientists first thought that animals transmitted SARS-CoV to humans. They now believe that an animal virus changed into a new, more deadly strain.
Causes
Droplets from coughing and sneezing and close human contact likely transmit the SARS virus. The respiratory droplets are probably absorbed into the body through the mucous membranes of the mouth, nose, and eyes.
This could be through:
hugging and kissing
sharing utensils for eating and drinking
speaking to someone within a distance of 3 feet
touching someone directly
A person with the virus can spread the infection by leaving respiratory droplets on objects, such as door handles, doorbells, and telephones. These are then picked up by someone else.
The virus is likely to remain active in the environment for several days.
