2019 Novel Coronavirus – A quick overview.

January 26, 2020

in December 2019
there was a cluster of pneumonia cases in China investigations found that it
was caused by a previously unknown virus now named the 2019 novel coronavirus in
this video we’ll take a quick look at what’s currently known about the virus
keep in mind that this is a new virus and what’s known about the virus now
might change in the future corona viruses are a large group of
viruses they consist of a core of genetic material surrounded by an
envelope with protein spikes this gives it the appearance of a crown crown in
Latin is called Corona and that’s how these viruses get their name there are
different types of corona viruses that cause a number of human diseases such as
respiratory and sometimes gastrointestinal disease the respiratory
disease can range from the common cold to pneumonia and in most people the
symptoms tend to be mild however there are some types of corona viruses that
can cause severe disease these include the severe acute respiratory syndrome
coronavirus in China in 2003 and the Middle East respiratory syndrome
coronavirus that was first identified in Saudi
Arabia in 2012 the 2019 novel coronavirus was first identified in
China it initially occurred in a group of people with pneumonia who’d been
associated with a seafood market in the city of Wuhan the disease has since
spread from those who were sick to others including family members and
healthcare staff there are hundreds of cases at present and the disease has
spread within China and also to a number of other countries so where did the
virus come from it’s known that corona viruses circulate in a range of animals
sometimes these viruses can make the jump from animals to humans this is
called a spillover and could be due to a range of factors such as mutations in
the virus or increased contact between humans and animals for example MERSCoV
is known to be transmitted from camels and SARSCo V from civet cats. the
animal reservoir of the 2019 novel coronavirus is not known yet. How is it
transmitted? the exact dynamics of how the virus is transmitted
is yet to be determined, in general respiratory viruses are usually
transmitted through droplets created when an infected person coughs or
sneezes or through something that has been contaminated with the virus so how
does the disease present? Well, from what is known so far there can be a number of
symptoms ranging from mild to severe there can be fever and respiratory
symptoms such as coughing shortness of breath. In more severe cases, there’s been
pneumonia kidney failure and death. The mortality rate is not known yet how can
we tell whether someone is infected the infection can be diagnosed by a test
called PCR or polymerase chain reaction this test identifies the virus based on
its genetic fingerprint there is currently no specific medication for the
virus and treatment is supportive care there’s currently no vaccine to protect
against the virus. How do we prevent transmission of the virus? This new virus
currently has a limited geographic spread, however there are a number of
standard hygiene practices that have been recommended to protect against
infection and further spread. These include washing hands, regularly covering
your mouth and nose after coughing or sneezing ,avoiding close contact with
those who are unwell the appropriate use of masks and personal protective
equipment, especially in a healthcare setting. Actions that can be taken to
prevent infection from an animal source include avoiding unnecessary contact
with animals washing hands after contact with animals or animal products and
ensuring that animal products are cooked thoroughly before they’re consumed.
That’s a quick look at this emerging infectious disease. Given that this
outbreak is evolving rapidly what’s known about this virus can change,

    Shouldn't the test be RT-PCR since it's an RNA virus?

  • Reply Thom Sieloff January 25, 2020 at 1:56 pm

    Do not be deceived. There is a patent for this coronavirus which was issued in 2018. Patent No. 10130701
    Filed July 23rd 2015, issued Nov 20th 2018.
    By the Pirbright Institute.

    If this CoV becomes pandemic, the only safe way to go into public will be with wrap-around safety glasses, the proper mask covering mouth & nose, disposable gloves and perhaps even a disposable gown, among other precautions…

    In what way is there not a death rate if there are statistics on cases and deaths? Why are you giving people advice on avoiding animals for a disease that is spreading from person to person?

    How does it have a "limited geographic spread" (3:22) when he said they don't understand how it's transmitted?

  • Reply Ianassa91 January 26, 2020 at 8:54 pm

    It's now known to also transmit via eyes, so you should cover your eyes too when in close proximity of people. Bunch of Wuhan medical staff got infected because they only covered their nose and mouth with a mask.
