Study Corona Part 4 The name “Coronavirus” is derived from the Latin word “corona”.

How was the name “coronavirus” formed?

The name coronavirus is derived from the Latin word “corona” , meaning ‘crown’ or ‘halo’, which refers to the characteristic appearance of virions (the infective form of the virus) by electron microscopy, which have a fringe of large, bulbous surface projections creating an image reminiscent(similar to) of a crown or of a solar corona.

How “coronavirus” is transmitted?

It is said that the “coronavirus” is transmitted primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes.

Study Corona Part 3 Viruses, and the diseases they cause, often have different names.

Did you know the virus and the disease have different names? 

Viruses, and the diseases they cause, often have different names.  For example, HIV is the virus that causes AIDS.  People often know the name of a disease, but not the name of the virus that causes it.

Like wise, “SARS-CoV-2” (Severe Acute Respiratory Syndrome Coronavirus 2) is the virus that causes the disease “COVID-19”.

Why virus and disease are named differently?

There are different processes, and purposes, for naming viruses and diseases. 

Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines. Virologists and the wider scientific community do this work, so viruses are named by the International Committee on Taxonomy of Viruses (ICTV).  

Diseases are named to enable discussion on disease prevention, spread, transmissibility, severity and treatment. Human disease preparedness and response is WHO’s role, so diseases are officially named by WHO in the International Classification of Diseases (ICD).

What is Covid-19?

COVID-19 is a new disease, caused by a newly discovered coronavirus that has not previously been seen in humans.

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.

OUTBREAK

The outbreak was first identified in Wuhan, Hubei, China, in December 2019. The World Health Organization (WHO) declared the outbreak to be a Public Health Emergency of International Concern on 30 January 2020 and recognized it as a pandemic on 11 March.

What is a Pandemic?

A pandemic (Derived from Greek word “Pandemos”. ‘Pan’ means ‘all’ and ‘demos’ means ‘people’) is an epidemic of disease that has spread across a large region, for instance multiple countries, continents or worldwide, affecting a substantial number of people.

Study Corona Part 1 – Coronaviruses are a large family of viruses which may cause illness in animals, birds and humans.

What is “Coronavirus/es” ?

Coronaviruses are a large family of viruses which may cause illness in animals, birds and humans.

Studies has helped to identify different symptoms in different species. In chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea.

And in humans, coronaviruses cause respiratory tract infections that can be mild, such as some cases of the common cold and others that can be lethal, such as SARS – Severe acute respiratory syndrome, MERS – Middle East respiratory syndrome (MERS), also known as COVID-19.

What is “Covid-19″(Coronavirus 2019)?

COVID-19 is an infectious disease caused by a new virus.
The disease causes respiratory illness with symptoms such as a cough, fever, and in more severe cases, difficulty in breathing.

Why is it called “Covid-19” or  “2019 Novel Coronavirus” ?

A series of unknown cause detected in Wuhan, China, was first reported to the WHO Country Office in China on 31 December 2019.

In related to this, on February 11, 2020 the World Health Organization announced an official name for the disease that was causing the ‘2019 novel coronavirus’ outbreak, first identified in Wuhan, China. The name of this disease is “Coronavirus Disease 2019” , abbreviated as COVID-19.

In COVID-19, ‘CO’ stands for ‘corona,’ ‘VI’ for ‘virus,’ and ‘D’ for disease. Formerly, this disease was referred to as “2019 novel (novel refers to new) coronavirus” or “2019-nCoV”. Here, the word Novel is derived from Latin word ‘Novellus’, means, ‘New, Young, Fresh’.

How to check fake coronavirus news and information on WhatsApp

WhatsApp does offer some features which can curb the spread of fake news and is also testing some more to deal with the problem.

Coronavirus, or COVID-19, is spreading fast and wide and not only do we need to take care of our health, we also need to make sure no false information is shared about it. In situations of chaos and pandemic, it is very easy for fake news to spread and most people are not informed enough to ignore it.

At times like these, fake news is not only dangerous, it is also fatal.

WhatsApp had established a system for users to report fake news during polls and also flag any news that seemed dubious. Right now there are a lot of messages doing the rounds on WhatsApp that carry medical information and preventive measures that are not correct and other information that’s wrong and detrimental along with fake numbers of deaths and reported cases.

Messages like these trigger more panic and very often mislead people. WhatsApp has over 1.5 billion users across the world, you can well imagine the impact it can have.

Luckily, WhatsApp does offer some features which can curb the spread of fake news and is also testing some more to deal with the menace.

One of the most basic ways to curb fake news is to carefully check the media such as photos and videos for edits that are misleading. The next thing is to verify the information with various reliable news sources.

In terms of features that have been introduced by WhatsApp to categorically control fake news, take a look at the following:

Forward mark

There is an arrow mark on top of the messages that have been forwarded. With this symbol one can conclude that the sender is not the original source of the message and he too has received this information from somewhere else.

In cases like these, double check anything you have received.

Frequently Forwarded Message

This was one of the new features introduced by WhatsApp last year. The messages in this category have two arrow marks instead of one. This is an indicator that the message has been floating around on the portal for quite some time and will need to be checked all the more.

Forwarding Info

The feature lets a person check the number of times the message has been forwarded. To see this information, tap on the message info option.

Forwarding Limit

WhatsApp has restricted the limit of forwarding messages at a time to 5 as opposed to the 20 earlier. This is probably one of the most effective ways to curb fake news.

If you spot any of these features on a message or a forward you have received, then verify the content before you believe it yourself and pass it on.
