Coronavirus Epidemic Update 27: Testing accuracy for COVID-19 (CT Scan vs. RT-PCR), California Cases

February 27, 2020


welcome to another MedCram update let’s
talk about California and testing but before we do let’s just review total
confirm eighty 2164 total deaths 2800 oh one total recovered thirty two thousand
eight hundred and ninety seven we see more of a continuation of what we’ve
been seeing in the past let’s go to the world ometer we gonna talk a little bit
about testing today and also the positivity rate and UK they have well
over seven thousand tests of which only thirteen are positive and that’s a very
low positivity rate of course in Italy where they actually have an outbreak
they’ve done over nine thousand tests of which only four hundred and seventy are
positive it’s about a five percent positivity rate in France two point two
positivity rate in Austria 321 tests of which two are positive and then in the
United States notice we’ve only done four hundred and forty five concluded
tests of which fourteen are positive and that’s around three point one positivity
rate these tests are not as sensitive as you may think that you’re going to be
surprised that the sensitivity on these tests are only around seventy percent
and so it is possible to have a negative test and to still be infected with the
corona virus we see that there are so far 334 new cases and one death in South
Korea and the number of confirmed cases expected to jump in the coming days as
health authorities have started testing more than two hundred and ten thousand
members of this church and Daegu if we look at the numbers coming out of China
and the rest of the world in terms of the total deaths that seems to be
leveling off and if we look at the number of daily new cases outside of
China that has hit its highest amounts ever on February 26 with daily cases of
569 I want to go to a local site Eyewitness News
here in Southern California a new case that has been detected in Northern
California in a resident who has not traveled overseas
couple things that I want you to be aware of this patient is a resident of
Solano County turns out that Solano County is the home to Travis Air Force
Base where Americans returning from overseas were quarantined the patient
was transferred back on February 19th so that was about a week ago from
undisclosed hospital to UC Davis health and that is the hospital in Sacramento
for the University of California Davis patient had already been intubated was
on a ventilator and was given droplet precautions orders because of an
undiagnosed and suspected viral condition so there are other viruses
that can do this now at the time it seems as though UC Davis had asked the
CDC for testing but this was not done at the time and if you go to the CDC
website it tells you what their requirements are for testing although
they do put a disclaimer that they will look at a case-by-case basis but
essentially unless you traveled to Wuhan or that part of China they weren’t
really going to be doing that kind of testing so it’s unclear how eventually
UC Davis was able to get CDC to test this patient but they did and eventually
on Sunday the CDC ordered the Cova 19 testing of the patient at that time the
patient was put into airborne precautions what does this mean it means
that anybody going into that room had to have an n95 mask and had to go into
contact isolation precautions that means they would have to wear a gown gloves
they may even have to wear I wear protection if they were not able to do
that then they would have to go under something called poppers where they
basically go in with a mask that was vented from Sunday to Wednesday it took
for the CDC to confirm finally that the patient’s test was positive the small
number of employees were to go home and monitor their temperature for any kind
of fever or things of that nature and the key here is to recognize
apparently this patient had no travel to that part of the world they go on to say
here at this time the patient’s exposure is unknown it’s possible that this could
be an instance of they call community spread of kovat 19
which would be the first time that this has happened in United States
it’s also possible however they said that the patient may have been exposed
to a returned traveler who was infected of course this brings up the issue of
anybody that comes when with fever or signs and symptoms of a viral illness
and shortness of breath could be potentially a carrier of this novel
coronavirus and that’s why it’s really important to have lots of personal
protective equipment at hospitals where they belong instead of running out at
hospital so it’s really important that hospitals have the ability to acquire
personal protective equipment because you don’t want to show up to a hospital
where the employees there or the doctors or the nurses don’t have the adequate
amount of protection so that they don’t pass the virus on to anybody else that
might show up at that hospital so please do not take masks and protective
equipment from hospitals for your own use but this really brings up a big
issue and that is how do you test people for coronavirus how do you know quickly
whether or not this person that’s coming in has this virus obviously if we see
here in this case it took them from Wednesday when they actually got the
causative test all the way from Sunday when they first order the tests you can
see that that’s not the optimal situation especially when we add to the
situation that this test is not really that sensitive meaning that if you have
a negative test you can absolutely rule it out so enter a study that I think is
going to be important and that is this science Daily News article which talks
about this article that was just published in radiology called CT
provides the best diagnosis for kovat 19:00 I will put a link to it in the
description below basically what they did is in China they looked at over a
thousand patients and they did this reverse transcriptase polymerase chain
reaction which is what rt-pcr stands for this is where you look for the actual
RNA of the patients and compared it to the classical findings that they see on
CT scan here’s another news item of the same article so title as CT provides
best diagnosis for kovat 19 and it says the study from China shows that chest CT
demonstrates better sensitivity than this blood test looking for the actual
pcr of the virus remember that halfway through the
epidemic last month they changed the criteria in the definition for the
diagnosis of kovat 19 so you can see here in a study of more than a thousand
patients that was published in the journal article radiology which we link
to so you can look at it for yourself chest CT actually outperformed lab
testing in the diagnosis of 2019 novel coronavirus and this was looked at in
Wuhan China so it’s important to understand that you have to make an
early diagnosis of kovat 19 if you’re going to isolate and you’re going to
prevent the spread of that disease as we talked about earlier in a early jam
article 41 percent of patients who contracted Co vyd 19 did so in the
hospital and the majority of those 41 percent were healthcare workers
according to the latest guidelines by the Chinese government the diagnosis
must be confirmed by reverse transcriptase polymerase chain reaction
or the gene sequencing they say here however that those throat samples are
only about 30 to 60 percent positive at initial presentation having a low
sensitivity implies that there’s going to be a lot of people who will be
negative initially and you’re gonna miss those people those people are going to
come through into your hospital and potentially infect other people
specifically people who are there to help and causing them to be taken out of
work and put into isolation most likely and so they say here that early
diagnosis of copán 19 is crucial for the disease treatment and control compared
to rt-pcr that is the genetic testing they say here that chest CT imaging may
be a more reliable practical and rapid method to diagnose and assess kovat 19
especially in the epidemic area so why did they think that well let’s take a
look and see this there was over a thousand patients who
underwent both CT chest and rt-pcr tests from January 6 to February 6 and what
they did was they looked at all of those people who had a positive PCR and there
was about six hundred and one of those and everybody that had a positive CT
scan and there was eight hundred and eighty eight of those and then they
asked the question well what’s the sensitivity what’s the specificity and
what’s the accuracy and what they found was that about eighty one percent of
patients with a negative rt-pcr but a positive CT scan were reclassified
as highly likely or probable cases with kovat 19 based on the comprehensive
analysis of clinical symptoms typical CT manifestations and dynamic CT follow-ups
what they mean by that they were getting worse and they were consistent they also
found in a lot of these that the initial tests may have been negative but that
follow-up tests turned positive confirming in a lot of these cases the
original CT findings let’s review those results the results showed that 59
percent of these patients that they tested had PCR results that were
positive eighty eight percent had positive CT scans they said that the
sensitivity and this is something that you want to be very very high in this
situation because something that is very sensitive means that if it is negative
you can practically rule it out and as it turned out that sensitivity of chest
CT was 97% based on positive rt-pcr results in patients with negative rt-pcr
results seventy-five percent of those patients had positive CT findings and of
those forty eight percent were highly likely cases so what we’re seeing here
is that CT scans may be the way to get a quick screening of whether or not your
patient with fever is likely to have kovat 19:00 but the question is what are
the findings on CT it’s good enough to know that you should get a CT but what
is it that you should be looking for I’m going to link in the description below
a youtube video describes the findings on CT scan of known cases of copán night
and that concludes our update for today realize that many of these videos are
made the evening before they get released because I still am working in
the intensive care unit seeing patients every single day and so this is
something that I do at the end of the day because we as healthcare providers
are on the front line and we have to be prepared thanks for joining us

    Thanks for all the effort. It is highly appreciated, We can all be thankful of the enormous effort of the medical staff in Wuhan and others that are currently figuring out how to treat this. It will greatly help in getting this under control eventually. I'm not looking forward to the effects of this pandemic though. This also explains the recurrence of Covid=19 in some recovered patients. If they were diagnosed with the RNA test found negative and released. But with Iran incapable of containing this it will be pretty impossible to contain. Even with all the restrictions on their travel. In some places this will be grim as well due to the fact that everyone has to get equipment at the same time. Stocks in Med supply companies look promising. How do they do on Wallstreet? With some luck you'll be infected with a long living non lethal variant of this, as most flu's evolve, but yeah. Don't stress 😉

    "The U.S is ready and prepared" Don't worry. That's why as of now I think it's safer to live in China and or Taiwan. It's as if the U.S is a third world country. Maybe Healthcare and the WHO should be looking at Youtube! Why is it that The people watching this seem smarter then the U.S politicians and the WHO?? ANYONE going in for any flu like symptoms should be given a mask. In an ideal world, they would be required to wear one. IF the U.S were really prepared ALL hospitals would be required to wear masks. oh yeah were all out!!! I can see a potential disaster happening. The dumb patient thinks he or she has corona… goes to doctor with no mask…. Doctor says its only a flu unless you been to China… Sends person home.. with a high R0….. you know he story. You can't make this stuff up!!!! Even in movies they aren't that stupid… or are they???

    Since the virus binds to ACE-2 in the GI tract as well, would it make sense to PCR test anal swabs instead of mouth or nose swabs? Seems a strange question, but aren't there more ACE-2 receptors there than in the throat or nose? Nasal and throat swabs rely on viral flow exhaled from the lungs, no?

    Here of course you're going to see more and more people test positive especially in California and Texas this is where the people were taken from the Diamond Princess cruise ship they should have gone through a mandatory 30 day quarantine here in the United States the minute they're playing touchdown on American soil however over 300 people on board a plane that had 14 infected known cases what is allowed to go back to their families and homes throughout the United States now these families are reporting illness as well everyone was told originally that a 14-day quarantine. Was sufficient but we know for a fact that 27 days is proven to show up time and time again in many patients not showing any symptoms of the virus until approximately the 27th day meaning of 14 day quarantine is useless not to mention the fact that on the Diamond Princess the very word quarantine should have never been used many doctors and scientists have agreed that the Diamond Princess was nothing more than a floating petri dish on the water because the passengers on board were forced to re breathe the same air over and over circulated throughout the ship by their air conditioning system whether you were on the first deck or the top deck you were breathing the same air so any sick people on board with spreading the virus through the air vents two other passengers whether they were quarantined to their rooms or not remember over 600 people were confirmed to have the virus on board the Diamond Princess there's over 3,000 people on board a cruise ship I guarantee you we will find out that every solitary person on board that cruise ship was infected and these are the people that were sent back to the US particularly 300 people on one plane from The Diamond Princess with 14 known infected cases on board one plane alone the CDC person in charge requested that her name not be put on the flying manifest she left the state department overrule her decision and let the plane fly back to the US knowing full well how serious this virus is

  • Reply James Conway February 27, 2020 at 9:12 pm

    Keep in mind many people were only given a throat swab at best as a test for this virus throat swabs are only effective if the person is already showing symptoms of the illness you can very easily come back with a false negative even though the person has the virus many people with this virus are known as carriers meaning they carry the disease around and spread it without knowing themselves they are infected many do not show any symptoms at all until approximately the 27th day of infection meaning of 14 day quarantine. Is useless everyone that is suspected of having this virus needs to have 3 blood tests and those blood tests must be done within a 30 day. Of time it is best to have the person in a sealed controlled are environment meaning that they cannot possibly spread it from person to person all health workers that are treating patients all this coronavirus illness need to be in a full hazmat suit with its own breathing apparatus remember this is an airborne disease paper mask do not I repeat do not stop the transmission of this disease a person does not have to sneeze on you they do not have to cop on you they don't have to touch you you only have to be in the same room as a sick person in order to come down with this virus I cannot emphasize enough it is Airborne

    I’ve been reading these daily, thank you for your videos. The linked article listed the CT scans as 86 % specific, but in pts with a history of possible exposure to Covid 19. I was wondering at the value of the CT scan for random pts with no epidemic exposure in their history, how specific would these results be considered? The person tested in Northern California was only tested with the PCR test after the persistence of the health care providers. Likely prior to the CT there was less caution with isolation techniques. I work in a hospital, I kind of shudder thinking about this.

  • Reply nicola voiculescu February 27, 2020 at 9:18 pm

    But what if after a positive CT scan you quarantine a patient that doesn’t have Covid 19 with other patients that have the disease. Wouldn’t there be a risk that the patient without the disease will get infected on top of the disease he already has, placing him in a potentially more dangerous situation ?

    Hello everyone, maybe you know some information, but I still want to say it again because I want more people to know. I am Chinese living in France, and the people here seem carelessly and unconcerned. A single RNA test is not reliable , and sometimes it takes four or five tests to determine the presence of the virus, although we sure that he is the patient. Patients often have mild or asymptomatic symptoms and do not require special treatment, but need isolation and basic medical care, this is why there are so many simple stadium-renovated hospitals in China. Until the vaccine is made, the only way is to wear a mask and stay away from the crowd, because you don't know who the patient is, and it is contagious even during the incubation period. If you have a mask, wear it when you go out , even if you think you are healthy.

    OK…I have a problem with this whole mask thing!! We have a CDC, a WHO, and so-called emergency planning people who are in charge of being prepared! Why are they not properly stocked? Was this scenario never thought of? I have a hard time believing that! Who dropped the ball making everyone ill-equipped? I am not going to set myself on fire to keep the ball droppers warm! NOPE! Maybe if they were shorthanded, someone should have opened a business to manufacture the supplies they would need. Oh, it is cheaper in China? Then should have bought many, many more!!! How irresponsible!! Disgustingly mismanaged and I am so mad at the idiotic carelessness that I have lost all faith in the "experts". But I have increased faith in them f-ing things up even more! The more who wear maks have a less chance to contract it and then require hospitalization in the first place. Sorry, the general public is the frontline! I think the managers of this stuff should go wipe their butts with their degrees and go lick some doorknobs! I most certainly do not want their disastrous vaccines either! Thay fail there too!

    In the first known case of community spread of Coronavirus our wonderful govt. agency, the CDC, screwed up Twice. First, they sent out defective test kits so hospitals couldn't test locally and had to send to the CDC for testing. They they refused to test a patient UC Berkeley suspected, since he didn't meet the criteria.

    The criteria is you were to China or contacted someone who was. So this guy hasn't – but has been walking around, possibly spreading the disease since it can spread without symptoms. But the CDC woudln't test him since they have Old criteria and want to pretend, for Political reasons, that this only comes from China. Stupid. Community spread means people who have nothing to do with China are now spreading it, so it can no longer be backtraced and isolated.

    Do NOT depend on your government to protect you. They are fine at bombing people but not so much at doing anything for Americans.

    Wait until coronavirus spreads and millions of Americans don't get testing or healthcare due to its Insane Bankrupting cost – causing it to spread even more. When enough "I hate free healthcare" people die of it, they might change their mind on Decent national healthcare that every Other civilized nation has.

    We are going to pay for the world's most Expensive (but not better) healthcare system if coronavirus spreads since many won't seek hideously expensive treatment as they spread the disease. (And Ca, right next door, now has non-China Community spread.)

    Coronavirus is Much more transmissible than flu, 20X more likely to kill you. It can live on surfaces for 9 days and is an aerosol.

    Meanwhile, WASHINGTON—The White House is taking steps to better coordinate messaging on the coronavirus outbreak, instructing senior officials to seek approval from Vice President Mike Pence’s office before speaking publicly about the epidemic, according to people familiar with the directive.

    Sounds like "Move on, nothing to see here."

    For those who would mention the 'reinfection' case in Japan, you have to know that respiratory Coronaviruses are prone to re-emergence (aka after recovery, the virus stays inside the cell undetected, and can reemergence when the immune system weakens again, like stress), like Feline Coronaviruses. This might be a huge issue because vaccination for FCV only prevents the symptoms, not the infection and the spread of the natural virus.

    On the plus side, COVID might end the entire Antivaxx campaign altogether, as herd immunity cannot protect against that kind of protection (as morbid as it may sound)

  • Reply Moonshot AudioVisual February 27, 2020 at 10:25 pm

    It wasn’t that they didn’t have the protective equipment, it’s that the CDC refused to test the patient and they didn’t know they needed to use the protective equipment. Should we now expect all hospital staff to be using airborne virus protocols whenever meeting any new patient reporting flu-like symptoms? Or any patient at all? Tools and procedures are worthless if you don’t use them until after it’s too late.

    There is something majorly wrong in America with our medical testing costs!! I have health insurance through my husbands employer. We now pay half of our premiums and still I can’t afford health care! I had a simple sonogram of my kidneys and had to pay out of pocket $350. That is absolutely insane! I can’t imagine how much a CT will cost much less hospital stay with a deductible of $6,000.

    Singapore's Changi Airport is a major SE Asia hub, at least in practice. My trip ATH->Phuket involved an 8 hour stop-over there. There should be an additional factor for the transmissibility function, one that is akin to temperature in a chemical reaction. Singapore's high 'temperature' would increase the spread rate. I hope the models are sophisticated enough to recognize this.
