Is.COVID-19 virus similar to SARS?
This new coronavirus is similar to SARS-CoV, so it was named SARS-CoV-2 The disease caused by the virus was named COVID-19 (COronVIrusDisease-2019) to show that it was discovered in 2019
Everything you need to know about SARS
was the result of infection by a coronavirus that scientists named SARS-associated coronavirus . SARS-CoV is related to SARS-CoV-2, the virus that causes COVID-19 infection.
While COVID-19 is currently affecting people around the world, no reports of new casesTrusted Source of SARS have surfaced since 2004.
spread to over 24 countries before health authorities managed to contain it. Nevertheless, between November 2002 to July 2003, there were 8,098Trusted Source cases worldwide and 774 deaths.
In the United States, there were eight laboratory-confirmed cases and no fatalities. All eight people who the illness affected had traveled to areas where SARS was prevalent.
What is SARS?
A coronavirus is a common form of virus that typically leads to upper respiratory tract illnesses, including the common cold.
Seven Trusted Source different kinds of coronavirus can infect humans. Four of these are common, and most people will experience at least one of them during their life.
The three other coronaviruses cause:
- SARS
- Middle East Respiratory Syndrome (MERS)
- COVID-19
The three most recent coronaviruses have all emerged since 2002 and are more likely to be life threatening than the previous ones.
Spread
Experts believe that coronaviruses, such as SARS-CoV, spread through close human contact and in droplets from coughing and sneezing. The viruses may be airborne or travel in ways that scientists do not yet know about.
The body likely absorbs the respiratory droplets through the mucous membranes of the mouth, nose, and eyes.
Ways of transmitting the virus may include:
- hugging and kissing
- sharing utensils for eating and drinking
- speaking to others within a distance of 3 feet
- touching someone directly
If droplets from one person land on an object such as a door handle or a telephone, someone else can pick up the virus if they touch these items.
In 2015, scientists Trusted Source found evidence that SARS-CoV might survive on a dry surface for extended periods, possibly for several months.
Causes
was a zoonotic disease, meaning it was of animal origin but passed on to humans.
The Centers for Disease Control and Prevention (CDC) note that 75%Trusted Source of emerging infectious diseases come from animals, including rabies and Ebola. Most zoonotic diseases originate in wild animals rather than pets or domestic animals.
Some animals can carry a virus without becoming sick because their bodies are accustomed to the virus. This fact means they are likely to have immunity.
Viruses can change, however. If a virus changes through contact with another type of animal, it can become unpredictable and possibly dangerous.
When a new virus first emerges, people do not have immunity. In time, the immune system develops antibodies for the new virus, and these antibodies equip it to fight the resulting disease.
When swine flu (H1N1) first appeared in 2009, for example, there were concerns that a pandemic could develop. Now, it is one of the seasonal flu strains that pharmacists include in the annual flu vaccine. Many people also have immunity to H1N1.
In 2019, a new coronavirus, which scientists identified as SARS-CoV-2, began making people sick in China. This is the virus causing the current COVID-19 pandemic.
