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

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
