WHO動画(英語):Novel coronavirus (2019-nCoV)~新型コロナウイルスについて

2月 20, 2020


WHO が出している、新型コロナウィルスに関する情報動画です。


ちなみに、このビデオの後、WHOは 新型コロナウィルス感染症 を「COVID-19」(コウヴィッ ナインティーン)と正式に命名したようですね。


以下に、YouTubeの英語字幕の内容を転載します。 だいたい、話している単位で改行しています。


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 and Latin is called Corona
and that’s how these viruses get their name

there are different types of corona viruses
that cause respiratory and sometimes gastrointestinal symptoms

respiratory disease can range from the common cold to pneumonia
and in most people the symptoms tend to be mild

there are some types of corona viruses that can cause severe disease
these include the severe acute respiratory syndrome coronavirus
first identified 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 and live animal market in the city of Wuhan

the disease has since spread from those who were sick to others including family members
and health care staff

there are many 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 increase contact between humans and animals

for example
murska v is known to be transmitted from camels
and Tsarskoe V from civet cats

the animal reservoir of the 2019 novel coronavirus is not known yet

how is it transmitted

the exact a mix 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

people most at risk of infection from the novel coronavirus
are those in close contact with animals
such as live animal market workers
and those who are caring for people infected with the virus
such as family members or healthcare workers

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

treatment and vaccines are in development

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 covering your mouth and nose when coughing or sneezing
with a medical mask tissue or flexed elbow
avoiding close contact with those who are unwell

the appropriate use of masks and personal protective equipment
especially in a healthcare setting

washing hands regularly with soap and water
or alcohol-based hand rub

actions that can be taken to prevent infection from an animal source include
avoiding unnecessary unprotected contact with animals

washing hands after contact with animals or animal products
and ensuring that animal products are cooked thoroughly before they’re consumed

it’s important to stay home if you’re feeling unwell

but if you have a fever cough and difficulty breathing
seek medical care early

and share your previous travel history with your healthcare provider

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
