What is Coronavirus Pandemic (COVID-19) ?

The 2019–20 coronavirus pandemic is an ongoing pandemic of coronavirus disease 2019 (COVID-19).
It is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

The outbreak was first identified in “Wuhan, Hubei, China, in December 2019“.
An investigation was launched in early January 2020. The cases mostly had links to the “Huanan Seafood Wholesale Market” and so the virus is thought to have a “zoonotic” origin.
The virus that caused the outbreak is known as SARS-CoV-2, a newly discovered virus closely related to “bat“

Report of World Health Organization (WHO)

Coronavirus disease (COVID-19) is an “infectious disease“caused by a newly discovered coronavirus.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment.
Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
The best way to prevent and slow down transmission is be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face.
The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).
At this time, there are no specific vaccines or treatments for COVID-19. However, there are many ongoing clinical trials evaluating potential treatments.

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.

Prevention Steps

To prevent infection and to slow transmission of COVID-19, do the following:

Wash your hands regularly with soap and water, or clean them with alcohol-based hand rub.
Maintain at least 1 metre distance between you and people coughing or sneezing.
Avoid touching your face.
Cover your mouth and nose when coughing or sneezing.
Stay home if you feel unwell.
Refrain from smoking and other activities that weaken the lungs.
Practice physical distancing by avoiding unnecessary travel and staying away from large groups of people.
Efforts to prevent the virus spreading include travel restrictions, quarantines, curfews, event postponements and cancellations, and facility closures.

Current case

As of 26 March, more than 471,000 cases of COVID-19 have been reported in more than 190 countries and territories, resulting in more than 21,200 deaths and more than 114,000 recoveries.
