Welcome to another video of simplified. This
video is about the new coronavirus disease, which has been declared a global health emergency
by The World Health Organization (WHO). This disease named Covid -19 by WHO has killed
more than 3,000 people worldwide following an outbreak in the central Chinese city of
Wuhan. More than 98,000 cases of the infection have been reported globally, most of them
~ 80,000 in China. Outside China, cases are reported in more
than 90 countries. ~80% of those cases are from just three countries: the Republic of
Korea, Iran and Italy. Recently, 30 cases have been reported in India
as well, out of which 3 have recovered. This video will be in the form of answer to
frequently asked questions such as what is coronavirus disease, how it is different from
seasonal flu virus. At the end of the video, we will see the guidelines provided by WHO
to protect ourselves. First obvious question is
What is coronavirus? According to the WHO, coronaviruses are a
family of viruses that cause illnesses ranging from the common cold to more severe diseases
such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome
(MERS). Coronaviruses are zoonotic, meaning they are
transmitted between animals and people. The name coronavirus comes from the Latin
word corona, meaning crown or halo. Under an electron microscope, the image of the virus
looks like a solar corona. What is Covid-19 – the illness that started
in Wuhan? The first report of the Wuhan coronavirus
came on December 31 2019. The novel coronavirus, is a new strain that had not been previously
identified in humans. Little is known about it, although human-to-human
transmission has been confirmed. Scientists aren’t certain where this virus originated What are the symptoms this coronavirus causes?
The most common symptoms are fever, tiredness, and dry cough. Some patients may have nasal
congestion, runny nose, sore throat or diarrhea. These symptoms are usually mild and begin
gradually. The virus can cause pneumonia. In severe cases there can be organ failure.
Some people become infected but don’t develop any symptoms and don’t feel unwell despite
having the virus. What is the amount of time between infection
and the onset of symptoms. Current estimates – range from one to 14 days.
Most infected people show symptoms within five to six days.
Who are the most affected people? Older people, and those with underlying medical
problems like high blood pressure, heart problems or diabetes, are more likely to develop serious
illness. Your chances depend on a range of factors
like age, sex and general health you are in. The death rates were lowest for the under
30s – eight deaths in 4,500 cases. Is the virus being transmitted from one person
to another? The disease can spread from person to person
through small droplets from the nose or mouth when a person with the disease coughs or exhales.
These droplets land on objects and surfaces around the person. Other people then catch
this disease by touching these objects or surfaces, then touching their eyes, nose or
mouth. It is spread via droplets not air.
Can CoVID-19 be caught from a person who has no symptoms?
The risk of catching COVID-19 from someone with no symptoms at all is very low. However,
many people with the disease experience only mild symptoms, particularly at the early stages.
It is therefore possible to catch COVID-19 from someone who has, for example, just a
mild cough and does not feel ill. Why is this worse than seasonal flu?
Both COVID-19 and flu cause respiratory disease and spread the same way, via small droplets
of fluid from the nose and mouth of someone who is sick.
However, there are some important differences between them.
First, COVID-19 does not transmit as efficiently as flu, from the data we have so far.
The second major difference is that COVID-19 causes more severe disease than seasonal flu.
While many people globally have built up immunity to seasonal flu strains, COVID-19 is a new
virus to which no one has immunity. That means more people are susceptible to infection.
Globally, about 3.4% of reported COVID-19 cases have died. By comparison, seasonal flu
generally kills far fewer than 1% of those infected.
Third, we have vaccines and therapeutics for seasonal flu, but at the moment there is no
vaccine and no specific treatment for COVID-19. Are antibiotics effective in preventing and
treating the new coronavirus? No, antibiotics do not work against viruses.
Is there a vaccine, drug or treatment for COVID-19?
Not yet. However, those affected should receive care to relieve symptoms. Most patients recover
thanks to supportive care. Recovery depends on the strength of the immune
system. Many of those who have died were already in poor health.
However, more than 20 vaccines are in development. How can I help protect myself?
Avoid close contact with people who are sick. Cover your mouth while coughing, and maintain
a distance of at least 1 meter (3 feet) from people who are coughing or sneezing. Avoid touching your eyes, nose, and mouth
with unwashed hands. Wash your hands often with soap for at least
20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer that contains
at least 60% alcohol. Thoroughly cook meat, eggs etc. Stay aware of the latest information on the
COVID-19 outbreak, available on the WHO website and through your national and local public
health authority. The silver lining is the low observed mortality
rate of Covid19, at 3.4% globally, as per the WHO based on the available data till date.
This rate is lesser than previous outbreaks like SARS or MERS. More than 55,000 people
have recovered from Covid-19 till now. Most people who become infected experience
mild illness and recover, but it can be more severe for others. Take care of your health
and protect others by taking necessary protective measures.
Also, share with authority if recently traveled to infected countries. Hope you found this video informative.
Thanks for watching.
