Give a short paragraph on SAARS
Answers
here is ur answer
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.
SARS is a viral respiratory illness that first emerged in China in November 2002, and later spread through international travel to 29 countries worldwide causing large outbreaks in Hong Kong; Taiwan; Singapore; Hanoi, Vietnam; and Toronto, Canada. According to the World Health Organization (WHO), from November 2002 to July 31, 2003, there were 8,098 cases of SARS; of these, 774 died.
On October 1, 2003, the Centers for Disease Control and Prevention (CDC), reported that there were 164 probable and suspect SARS cases in the United States, of which only eight had laboratory evidence of SARS. There were no deaths due to SARS in the US. Most of the U.S. SARS cases were among travelers returning from other parts of the world with SARS. There were 11 suspect and probable SARS cases investigated by the Minnesota Department of Health; many of these individuals had an alternative diagnosis that could explain their symptoms.
