All About Corona Virus?

what is corona virus?

Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that can range from mild to lethal. Mild illnesses include some cases of the common cold (which is caused also by certain other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS, and COVID-19. Symptoms in other species vary: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are as yet no vaccines or antiviral drugs to prevent or treat human coronavirus infections.

How Does the Virus Look?

Why it is Named As Corona?

The name "coronavirus" comes from the Latin corona, which means crown or halo. It refers to the fringe around microscopic virus particles that have spiky edge resembling a royal crown. They are commonly found in animals, but there are seven coronaviruses that are zoonotic, meaning they can jump from animals to humans. 

ORIGIN OF COVID-19?

In the public mind, the origin story of coronavirus seems well fixed: in late 2019 someone at the now world-famous Huanan seafood market in Wuhan was infected with a virus from an animal.

The rest is part of an awful history still in the making, with Covid-19 spreading from that first cluster in the capital of China’s Hubei province to a pandemic that has killed about 80,000 people so far.

Stock footage of pangolins – a scaly mammal that looks like an anteater – have made it on to news bulletins, suggesting this animal was the staging post for the virus before it spread to humans.

But there is uncertainty about several aspects of the Covid-19 origin story that scientists are trying hard to unravel, including which species passed it to a human. They’re trying hard because knowing how a pandemic starts is a key to stopping the next one.

How does it affected on Human?

The virus is spread through droplets transmitted into the air from coughing or sneezing, which people nearby can take in through their nose, mouth or eyes. The viral particles in these droplets travel quickly to the back of your nasal passages and to the mucous membranes in the back of your throat, attaching to a particular receptor in cells, beginning there.

Coronavirus particles have spiked proteins sticking out from their surfaces, and these spikes hook onto cell membranes, allowing the virus’s genetic material to enter the human cell.

That genetic material proceeds to “hijack the metabolism of the cell and say, in effect, ‘Don’t do your usual job. Your job now is to help me multiply and make the virus’,

Symptoms of COVID-19?

The COVID-19 virus affects different people in different ways.  COVID-19 is a respiratory disease and most infected people will develop mild to moderate symptoms and recover without requiring special treatment.  People who have underlying medical conditions and those over 60 years old have a higher risk of developing severe disease and death.

Common symptoms include:

• fever
• tiredness
• dry cough.

Other symptoms include:

• shortness of breath
• aches and pains
• sore throat
• and very few people will report diarrhoea, nausea or a runny nose.

People with mild symptoms who are otherwise healthy should self-isolate and contact their medical provider or a COVID-19 information line for advice on testing and referral.

People with fever, cough or difficulty breathing should call their doctor and seek medical attention.

HOW TO BE AWARE OF COVID-19?

Practicing hand and respiratory hygiene is important at ALL times and is the best way to protect others and yourself.

1.When possible maintain at least a 1 metre (3 feet) distance between yourself and others. This is especially important if you are standing by someone who is coughing or sneezing. Since some infected persons may not yet be exhibiting symptoms or their symptoms may be mild, maintaining a physical distance with everyone is a good idea if you are in an area where COVID-19 is circulating

2.Wash your hand at least 10 to 20 times in a day.

3.Stay at home dont go outside.

4.Always wear a mask while going outside.

5.Maintain social distance.

6.Eat just cooked food.

7.Dont exposed yourself into a corona affected area.
