In early 2020, a new virus began making headlines due to the unprecedented speed of its worldwide transmission.
From its origins in a food market in Wuhan, China, to countries as far-flung as the United States and the Philippines in December 2019, the virus (officially named SARS-CoV-2) has led to rising deaths with hundreds of thousands Has influenced Now the toll is over 17,000.
The disease caused by infection with SARS-CoV-2 is called COVID-19, which is for coronovirus disease 2019.
Despite the global panic in the news about this virus, you are unlikely to contract SARS-CoV-2 unless you are in contact with someone with SARS-CoV-2 infection.
Expose some myths. Read on to know how this 2019 coronovirus spreads, how it is similar and different from other coronaviruses, and how to prevent it from spreading to others if you suspect that you have contracted this virus.
What are the symptoms?
Doctors are learning new things about this virus every day. So far, we know that COVID-19 may initially cause no symptoms for some people.
You can take the virus for 2 days or 2 weeks before you notice the symptoms.
Some common symptoms that have been specifically linked to COVID-19 include:
shortness of breath
having a cough that gets more severe over time
a low-grade fever that gradually increases in temperature
These symptoms may become more severe in some people. Call emergency medical services if you or someone you care for have any of the following symptoms:
blue lips or face
persistent pain or pressure in the chest
The full list of symptoms is still being investigated.
COVID-19 versus the flu
We are still learning about whether 2019 coronovirus is less deadly than seasonal flu.
It is difficult to determine because the total number of cases (including mild cases in people who do not seek treatment or undergo an investigation) is unknown. However, early evidence suggests that this coronovirus causes more deaths than seasonal flu.
In the joint phase, an estimated 0.06 to 0.1 percent of people who developed the flu died in the 2019-2020 flu season (as of March 14, 2020). According to the Centers for Disease Control and Prevention (CDC) Trusted Source, this compares to 1.2 percent of confirmed cases of COVID-19 in the United States.
Here are some common symptoms of the flu:
runny or stuffy nose
What causes coronaviruses?
Coronaviruses are zoonotic. This means that they develop in animals before they develop into humans.
For the virus to move from animal to humans, a person has to come in close contact with an animal that gets an infection.
Once the virus develops in people, the coronavirus can spread from person to person through respiratory drops. It is a technical name for a wet thing that moves through the air when coughing or sneezing.
Viral material seeps into these droplets and can be inhaled into the respiratory tract (your windpipe and lungs), where the virus can then cause infection.
The 2019 coronavirus is definitely not associated with a specific animal.
Researchers believe the virus may have been passed from bats to another animal – either snakes or pangolins – and then transmitted to humans. This transmission is likely in the open food market in Wuhan, China.
