Coronaviruses are a family of hundreds of viruses that can cause fever, respiratory problems, and sometimes gastrointestinal symptoms too. In humans they’re typically spread via airborne droplets of fluid produced by infected individuals.
First described in detail in the 1960s, the coronavirus gets its name from a distinctive corona or ‘crown’ of sugary-proteins that projects from the envelope surrounding the particle. The 2019 novel coronavirus is one of seven members of this family known to infect humans, and the third in the past three decades to jump from animals to humans.
How did the recent outbreak of corona virus occur?
The recent out break of corona virus is believed to ave occurred in markets of illegal wildlife in the central Chinese city of Wuhan. Chinese health authorities ans WHO(World Health Organization) are investigating the out break of corona virus.
severe acute respiratory syndrome (SARS-CoV)
SARS was first recognised as a distinct strain of coronavirus in 2003. The source of the virus has never been clear, though the first human infections can be traced back to the Chinese province of Guangdong in 2002.
Snakes were originally suspected as a potential source for the outbreak, though other experts have deemed this unlikely and proposed bats instead.
What are the symptoms of a corona virus?
People who are older or have existing medical conditions, such as heart disease, may be at higher risk of serious illness. This is similar to what is seen with other respiratory illnesses, such as influenza.
Coronaviruses can cause a variety of symptoms in different animals. While some strains cause diarrhoea in pigs and in turkeys, most of the time infections can be as same as bad cold, causing mild to moderate upper respiratory problems such as a runny nose and sore throat and dry and unbearable cough.
How does corona virus spread?
Researchers are trying very hard to understand how SARS-CoV-2 spreads between humans.
It’s likely to be transmitted in droplets from coughing or sneezes, and the virus has a two- to 14-day incubation period. That means one could be infectious for quite a while before symptoms like fever, cough, or shortness of breath emerge.
How to avoid catching the coronavirus?
- Avoid close contact with people who are sick. Maintain at least three feet distance between yourself and anyone who is coughing or sneezing.
- Avoid touching your eyes, nose, and mouth even if you are not infected by cold and cough.
- Clean all of your tech equipment. Just like your hands, your smartphone and keyboard and headphones and anything else gets germs on it.
- Wash your hands often with soap and water for minimum 20 seconds, especially after going to the bathroom, before eating, and after blowing your nose, coughing, or sneezing.
According to preliminary estimates from the Centers for Disease Control and Prevention, the 2019–2020 flu caused 19 million to 25 million illnesses and up to 25,000 deaths. The Covid-19 numbers are harder to calculate because it’s not yet clear how many people are infected.
