welcome to another MedCram update so first things first we have 427 deaths
-
and 20600 confirmed cases and again we look at this ratio here not as saying
-
that this is a death rate or a fatality rate it's just a ratio of confirmed
-
deaths divided by confirmed cases but as we predicted the total recover has gone
-
up and I refer you once again to the dashboard at the Johns Hopkins
-
University de site for the Wuhan coronavirus so there are a lot of things
-
to go over today first of all there was a paper that was trying to calculate the
-
RO or the basic reproduction number this is basically if the virus is in somebody
-
how many people does that virus get passed on to
-
you
-
and I will put a link to the in a description shows about 2.2 for
-
23.5 8 is the number which is respectable number measles is of course
-
one of the worst it's about 14 or 15 next big thing three new cases in
-
California and currently California has about six out of the eleven cases in the
-
United States and that's not surprising given that California is probably the
-
biggest destination from Asia to the United States the second death outside
-
of China if you want to consider hong kong out of china was in a relatively
-
young gentleman although apparently this guy had underlying illness other big
-
thing in the news patient in Washington state was released to home isolation and
-
the key here is home isolation so they don't say much about him however the
-
thing that I would like to know is whether or not he's virus free why did
-
he go home on home isolation and is in fact is he's still infectious and he's
-
just not sick enough to be in the hospital and that's a that's an
-
interesting question to note but we'll have to see I've gotten a lot of
-
comments asking about stuff from China like mail or packages we just talked
-
about yesterday how on a door handled they were able to pick up the RNA of the
-
corona virus on PCR and I've seen at least two or three articles now with
-
experts biologists looking at the corona virus and saying that mail from China is
-
fine now we bring up bats so there seems to be some disagreement among scientists
-
when this originally came out there was a study that showed that the Wu Hank
-
rotavirus was very similar and probably most similar to that found in snakes
-
there seems to be some additional data that it could be from bats the news
-
there are more evacuations coming and the US government is going to be taking
-
those two Air Force bases since that seemed to work out well for March Air
-
Reserve Base in Southern California a Travis Air Force Base seems to be one of
-
the ones that's targeted they need to have big enough places where they can
-
have single rooms to isolate and as we mentioned yesterday in our video there
-
was two people on germán flight to Germany with German
-
nationals that tested positive for the corona virus finally in weird news
-
Pakistan is bucking the trend they're good or resumed flights with China which
-
leave a lot of people scratching their heads because they believe that Pakistan
-
is in no way able to deal with a corona virus outbreak there they do note in
-
some of the articles that I read that there is a pretty strong relationship
-
between China and Pakistan of recent notes China has loaned them billions of
-
dollars for infrastructure right now there are no cases in Pakistan and what
-
about the fact that this is a year that the Olympics are occurring in the Summer
-
Olympics in Tokyo so the question isn't where are we gonna be when the summer
-
comes around and I will put some links in the description of epidemiologists
-
hoping that the summer is a slowdown because generally these viruses don't do
-
very well in the summertime but remember this is a completely novel virus to the
-
human body and the diamond Princess cruise ship is in complete quarantine
-
just off the coast of Japan and that's because there was one person in late
-
January that tested positive for the Wu hen Khurana virus and currently there
-
are seven people on board that are ill of course that's not too surprising if
-
you've been on a cruise ship you'll know that you're bound to get somebody that's
-
ill the testing is not going to be completed on these people until Tuesday
-
night okay the next thing I want to talk about is they check that this patient
-
out in Washington State and found that he definitely tested positive in his
-
stool for the RNA for this wuhan corona virus well this reminded people of what
-
happened back in 2002 with SARS and as you may recall and you'll also link to a
-
paper that describes this that there was a whole outbreak I mean hundreds of
-
people were exposed to one man having the SARS virus and where is this gonna
-
happen and and that's the next thing we got to talk about is public restrooms
-
public bathrooms there's some good evidence even that
-
Chinese are agreeing that this is a potential issue as to how this thing can
-
be spread just the flushing of the toilet itself that can also aerosolize
-
things just by flushing so the question is what do you do well I've got no
-
studies can't tell you for a fact that this works but here's some steps that I
-
think you may want to consider number one is avoid public bathrooms if
-
possible number two wash hands and what I would
-
say here is use paper towels if possible to touch anything in public bathrooms so
-
walking into the bathroom usually it's a push you can use your foot obviously you
-
want to have a barrier between you and the toilet seat when you're done if you
-
can you probably want to close the toilet cover so if you flush it doesn't
-
aerosolize of course that's gonna be for you not to spread it's that someone else
-
but of course you can't prevent other people from doing that washing your
-
hands for at least 20 seconds okay some people say sing happy birthday and
-
you're mine twice to get to 20 seconds I would also carry hand sanitizer you
-
would not believe how many times you touch your face you scratch your nose
-
you put your finger in your mouth these are all entryways another big thing if
-
you have children teach them all of these things so the second thing I
-
wanted to get to really quickly was this Lancet article where they included now
-
99 which is the most to date people with pneumonia with the Wuhan coronavirus and
-
the average age here was 55 years old 67% men 50% chronic disease 83% had
-
fever 82% had coughed 31% had shortness of breath
-
interestingly only 2% had diarrhoea 17% had a RDS and 11% died as opposed to the
-
original paper which said 15% now we're getting a little bit more granular
-
because we have more n now this brings us to another interesting thing which
-
was the prediction score for those that were going to die followed something
-
called an M u L B Estie a score for viral pneumonia and
-
I'll include that in the description below it's a very nice article and what
-
did it look for well there are a number of things that you could look for in
-
these patients to help tell you is this one that's going to die or is this
-
someone that's not going to die number one was multi lowbar infiltrates number
-
two was lymphocytes less than 0.8 number three was bacterial co-infection number
-
six was someone who had hypertension which I'll abbreviate HTN number seven
-
was age greater than sixty years of age so for multi lowbar infiltrates they got
-
five points and you want to have the least amount of points possible for low
-
lymphocytes they got four points for bacterial infection four points acute
-
smoker three points if you were a quit smoker two points hypertension was two
-
points in age greater than sixty was two points so I'll give you some examples
-
here if you had zero points your chances of dying from viral pneumonia was 0.47%
-
if you had six points it was two point nine percent if you had twelve points it
-
was fifteen percent and if it was twenty two points and of course this can go up
-
to as high as twenty two points but it was basically greater than 69 percent
-
and this was a very nice prediction method to determine in a viral pneumonia
-
if someone would die and it followed it pretty closely even for other viruses
-
so the one that I see a lot comments is this coronavirus and HIV and
-
this probably started out because of a paper that was uploaded to bio
-
rx IV not too long ago that found by looking at the RNA that there were four
-
regions in the novel coronavirus that looked like they had come from HIV and
-
this was a paper that was not peer-reviewed it was uploaded to a
-
particular part of the site where those papers can go before they get reviewed
-
by other scientists there was a disclaimer in that area that
-
specifically said that but the conspiracy theories abounded and I have
-
to admit I saw it as well and I was concerned about it because of what the
-
implications could mean these HIV stretches were coding for gp120 which is
-
involved potentially in the binding site of cd4 cells so what they actually found
-
out two of those areas are actually found in bat coronavirus okay so it's
-
normally there and the other two one is found in HIV but it's only six amino
-
acids long and I don't think that based on the number of matches that they have
-
to go through the fact that you would find something that matches six amino
-
acids would be a wash statistically speaking nevertheless this paper was
-
removed Sunday by the author's saying that they could have relook at this but
-
people will say well why are we using HIV meds then in this current outbreak
-
why are they trying it and why are people getting better on the HIV meds
-
well this is not a new theory back when SARS broke out in 2002 they also used
-
HIV medications well why well because corona virus is an RNA virus and HIV is
-
also an RNA virus and so so in the machinery and getting RNA viruses into
-
species that have DNA primarily they're going to be very similar and they may
-
help it of course we already have it we know that it's relatively safe and so
-
there's these questions about people being readmitted to the hospital people
-
who have recovered yet they get sick again only to have to end up on this
-
well I haven't seen any cases out there of this
-
particularly if you see any I would love to hear from you please put actual case
-
reports in there there was the the gentleman in the Philippines who did die
-
but you've got to realize that a lot of these people who have viral infections
-
will get secondary bacterial infections and in fact I see this all the time
-
personally in my practice is people will come in to the hospital with severe
-
bacterial pneumonia but if you check their history they've had a viral
-
infection prior to that that they've got better from the virus moves in it de
-
nudes the respiratory epithelium and then the bacteria moves in as an
-
opportunistic infection so these people being readmitted to the hospital could
-
be opportunistic infections of bacteria well you say well what about the fact
-
that a lot of these people have decreased white blood cells I mean
-
couldn't this be the virus tearing up cd4 cells T helper cells well if you
-
look back at that article that I was talking about with the viral pneumonia
-
is you'll see that part of the way they differentiate is that many times
-
regardless of the viral pneumonia there's going to be a lymphocyte count
-
that's low in fact that was one of the criteria that we used in figuring out
-
whether or not the patients actually have a higher risk of dying that
-
remember that was the MU L B sta score and these people that are being
-
discharged from the hospital as part of their criteria at least in China is that
-
their viral loads are undetectable they cannot detect the virus on PCR so the
-
point of this is be careful there's a lot of theories out there that may be
-
based on less than scientific data and I guess I'll take this opportunity to
-
thank everyone for all of the nice comments I'm glad that this is helpful
-
thanks for joining us and remember what we said about hand-washing pray for this
-
to turn around and we will see you next time
