It is the family of viruses that causes respiratory issues in humans. They are called “corona” because of the crown-like spikes on the surface of the virus. Severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the common cold are examples of COVID_19(coronavirus) that cause illness in humans.

 It was first reported in China in December 2019. It has since spread to every country in the world. 

Where do they come from? 

Coronaviruses are often found in bats, cats, and camels. The viruses live in but don’t infect the animals. Sometimes these viruses then spread to different animal species. The viruses may change (mutate) as they transfer to other species. Eventually, the virus can jump from animal species and begin to infect humans. In the case of SARS-CoV-19, the first people infected are thought to have contracted the virus at a food market that sold meat, fish, and living animals. 

Coronavirus is likely to spread: 

The virus travels in respiratory droplets released into the air when an infected person coughs, sneezes, talks, sings, or breathes near you.

You can also get coronavirus from close contact (touching, shaking hands) with an infected person and then touching your face. 

Persons at greatest risk of contracting COVID-19 include those who: 

Live in or have recently traveled to an area with ongoing active spread. 

Have had close contact with a person who has a laboratory-confirmed or a suspected case of the COVID-19 virus. close contact means a distance maintained of about 3 meters.

Are you over the age of 60 with pre-existing medical conditions or a weakened immune system? 

COVID-19 symptoms vary from person to person. Some infected people don’t develop any symptoms (asymptomatic). In general, people with COVID-19 report some of the following symptoms: 

Fever or chills. 

Cough. 

Shortness of breath or difficulty breathing. 

Tiredness. 

Muscle or body aches. 

Headaches. 

Net loss of taste or smell. 

Sore throat. 

Congestion or runny nose. 

Nausea or vomiting. 

Diarrhea. 

Situation in 2019 (covid-19)

At the start of covid 19, everybody knows it is a deadly virus and millions of people lost their lives. nobody knows about what is this and what is the treatment for this virus. 

salute all the medical staff all over the world who serve the people at that time even though most of the doctors and other medical staff were also affected and many lost their own lives. 

only precautions we know about this virus, stay at home, wash our hands, etc. 

In 2022 things are better but corona is not gone.
