welcome to another MedCram lecture one of the things that's in the news and

様態の副詞

hopefully goes away real soon is the corona virus epidemic from 2019 as it

turns out it started on the last day of 2019 and has been with us in 2020 let's

talk a little bit about corona virus that virus that seems to have come from

Wuhan China let's talk a little bit about what's going on and the updates so

it seems as though this virus came from as we mentioned Wuhan China they've

seemed to have pinpointed this to an animal market in fact a number of the

people that were hospitalized and we'll talk about that article in The Lancet

came from this animal market and as of January 25th 2020 they estimate about

1300 people have been infected and about 41 people to date as of January 25th

have died and of course this number is expected to go up where is it spread to

well other than China and Asia this has spread already to Australia France and

the United States specifically two cases one in Chicago a woman in Chicago and a

man in Washington State and we'll talk more about that we expect that to go up

but what really is going on with a corona virus and why is this one so

different so we've known about corona viruses for a long time it's an RNA

virus so we know that and let's face it there's our there's corona viruses all

over the place in humans and they usually cause the common cold what's

unusual about this one is that this one seems to have jumped from one that is

already in an animal to that being in a human so there's tons of corona viruses

that infect animals but what has seemed to have happened here for the first time

as this one has jumped into a human that a human hasn't seen before and how could

that happen well it could be from a mutation and

that's typically what happens is there's a mutation in the protein in this virus

that allows it to bind to human proteins and that

allows the virus to get inside of the cells of humans and if it can replicate

then it can spread throughout that human body and then perhaps spread to another

human body so what needs to happen there has to be a mutation and that mutation

is already there in the animal and then there has to be close contact with that

animal either living with that animal or eating that animal to get that mutated

virus that normally lives in an animal into the human being so when that virus

then gets into the human being it's got to be able to replicate so that there's

more viruses and then it has to be able to spread to another human being and

that is what's gonna cause an epidemic so how does that happen well there's got

to be replication as we just said and they believe that that virus can

replicate inside the human and then how does it spread to another human as

opposed to just another animal spreading it to another human well the way that

you get an epidemic is with replication occurring inside that person that index

infected person and then it spreads how would it spread well it could spread by

airborne so that's why you'd want to wear a mask or close contacts so a loved

one contaminated surfaces so that's why you'd have to wash your hands very

carefully or rarely fecal contamination but these are the things that you can

attack to prevent the spread of this virus but we've seen this before and

where have we seen this corona virus type of thing happening before well you

all may remember SARS back in 2002 this was from bats which is where the virus

was infecting a mammal called civets and then they being eaten or living close to

humans fortunately we haven't seen any more infections since 2004 but that was

a big thing back in 2002 then MERS which have to do with the Middle East have to

do with camels viruses that lived in the camel and if you ate the camel or drank

the camel's milk you could get this type of infection now

the new one is humans with this infection called n Co V which is what

they're calling it now so n Co V is the new coronavirus that's coming out of

Wuhan China 2019 and that has gone into humans but the question is who did it

come from what is the host so what they did was

they sequenced this virus in the Journal of medical virology and we'll put a link

to this article in our description below so you can see it what they did was they

sequenced this RNA and they compared it to 200 other RNA virus coronaviruses

that are known to infect animals and the one they came up with which was a match

that was pretty close was one in snakes and so what their conclusion was and we

don't know that this is in fact true but this was their conclusion was that in

the wuhan animal market there must have been a snake that had a mutated corona

virus which they're now calling n co v somebody either ate it or was close to

it or somehow got contact with it and that virus just started to replicate

inside of that person and that person spread it and as we'll see in The Lancet

article which will also put a link to in our description below

they found a whole family that had this virus that were hospitalized and we'll

talk about the symptoms and the mortality and things of that nature here

coming up in our second video this is what they think is going on in China

with a corona virus and this is big news right now because millions and millions

of people are quarantined in China as I'm making this video so in our next

video we'll talk about the symptoms and what they're doing for treatment

vaccines and what you can do to prevent you getting this corona virus thanks for
