Make the world you need.
>>> IT STILL APPEARS TO BE RARE Make the world you need.
>>> IT STILL APPEARS TO BE RARE
THAT AN ASYMPTOMATIC INDIVIDUAL
TRANSMITS ONWARD.
WHAT WE WANT TO BE FOCUSED ON IS
FOLLOWING THE SYMPTOMATIC CASES.
IF WE FOLLOWED ALL THE
SYMPTOMATIC CASES BECAUSE WE
KNOW THIS IS A RESPIRATORY
PATHOGEN, IF WE ACTUALLY
FOLLOWED ALL THE SYMPTOMATIC
CASES, ISOLATED THOSE CASES,
FOLLOWED THE CONTACTS AND
QUARANTINED THE CONTACTS WE
WOULD DRASTICALLY REDUCE — I
WOULD LOVE TO GIVE A PROPORTION
OF HOW MUCH TRANSMISSION WE
WOULD STOP.
>> THE WORLD HEALTH ORGANIZATION
YESTERDAY CASTING DOUBT AND
CAUSING CONFUSION ABOUT THE
SPREAD OF THE CORONAVIRUS
THROUGH ASYMPTOMATIC INFECTIONS.
YOU HEARD A TOP OFFICIAL CALLING
ASYMPTOMATIC TRANSMISSION RARE.
THE NEW CONCLUSION WAS DRAWN
FROM CONTACT TRACING DATA FROM
SEVERAL COUNTRIES.
HOWEVER, PRELIMINARY EVIDENCE
FROM THE EARLIEST OUTBREAKS
INDICATED THE VIRUS COULD SPREAD
FROM PERSON-TO-PERSON CONTACT
EVEN IF THE CARRIER DID NOT HAVE
SYMPTOMS.
NOW THE W.H.O. SAYS WHILE
ASYMPTOMATIC SPREAD CAN OCCUR,
IT IS NOT THE MAIN WAY IT IS
BEING TRANSMITTED.
THE COMMENTS ARE RAISING
QUESTIONS FROM LEADING HEALTH
EXPERTS.
THE DIRECTOR AT THE HARVARD
GLOBAL HEALTH INSTITUTE BLAMED
THE W.H.O. FOR CREATING
CONFUSION, TWEETING OUT
COMMUNICATION FROM THE W.H.O. IS
NOT STELLAR AND SUCH
COMMUNICATION SHOULD BE
ACCOMPANIED BY DATA.
HE CALLS THE ASYMPTOMATIC SPREAD
THE ACHILLE’S HEEL OF THE
OUTBREAK.
QUESTIONS ALSO RISING OVER WHY
THE AGENCY RECENTLY CHANGED ITS
GUIDANCE ON WEARING MASKS.
PREVIOUSLY THE W.H.O.
RECOMMENDED ONLY HEALTH CARE
WORKERS, PEOPLE WITH COVID-19
AND THEIR CARE GIVERS WEAR
MEDICAL MASKS.
ON FRIDAY THE W.H.O. CHANGED ITS
GUIDANCE AND NOW IS ADVISEING IN
AREAS WHERE THE VIRUS IS
SPREADING HEALTHY PEOPLE SHOULD
WEAR FABRIC MASKS WHEN UNABLE TO
SOCIALLY DISTANCE.
LET’S TRY TO MAKE SENSE OF THAT,
JOINING US PROFESSOR AND VICE
PRO VOES FOR GLOBAL INITIATIVES
DR. EZEKIEL EMMANUEL.
AND COHOST OF THE PODCAST AND
MAKING THE CALL AND AUTHOR OF
THE NEW BOOK ENTITLED "WHICH
COUNTRY HAS THE BEST HEALTH
CARE".
ALSO WITH US, "MORNING JOE"
CHIEF MEDICAL CORRESPONDENT
DR. DAVE CAMPBELL.
GOOD MORNING, GOOD TO HAVE YOU
BOTH WITH US.
DR. EMMANUEL WE’LL START WITH
YOU.
WHEN THE W.H.O. SAYS
ASYMPTOMATIC TRANSMISSION IS
RARE WE’VE BEEN TOLD FOR THESE
MONTHS NOW THAT PART OF THE IDEA
OF STAYING AT HOME IS YOU COULD
HAVE CORONAVIRUS AND NOT KNOW IT
AND JUST THE ACT OF GOING TO A
GROCERY STORE OR RESTAURANT YOU
COULD BE SPREADING IT TO PEOPLE
WITHOUT KNOWING IT.
WHAT DID YOU MAKE OF THE W.H.O.
COMMENTS YESTERDAY?
>> WELL, I THINK THE OFFICIAL
WENT OVERBOARD COMPARED TO WHAT
THE ACTUAL OFFICIAL DOCUMENT,
WHICH I HAVE HERE, SAID.
SO IF YOU ACTUALLY READ THE
DOCUMENT CAREFULLY, IT SAYS THAT
THERE ARE THREE STUDIES THAT
LOOK AT SPREAD WITHOUT SYMPTOMS.
PART OF THE PROBLEM, AND THIS IS
WHAT THEY DIDN’T MAKE CLEAR IS,
ASYMPTOMATIC SPREAD IS WHEN YOU
NEVER DEVELOP SYMPTOMS.
YOU CAN ONLY TELL THAT AT THE
VERY END.
ONE OF THE THINGS WE KNOW IS
THAT A LOT OF PEOPLE ARE MOST
INFECTIOUS, ONE TO THREE DAYS
BEFORE THEY HAVE SYMPTOMS.
THEY LOOK ASYMPTOMATIC BECAUSE
THEY DON’T KNOW THEY HAVE THE
DISEASE BUT THEY CAN STILL
SPREAD IT.
WHILE THEY’RE NOT TRULY
ASYMPTOMATIC BECAUSE THEY
EVENTUALLY DEVELOP SYMPTOMS BUT
THEY LOOK ASYMPTOMATIC.
SO IF THEY WERE MORE CAREFUL
THEY WOULD HAVE SAID YOU CAN
SPREAD IT WHEN YOU’RE PRE-
PRE-SYMPTOMATIC AND DEVELOP
SYMPTOMS AND THAT MAKES IT
EASIER TO TRACE.
BUT PEOPLE WITHOUT SYMPTOMS CAN
SPREAD THE DISEASE, THAT’S THE
IMPORTANT POINT.
PEOPLE WHO HAVEN’T DEVELOPED
SYMPTOMS YET, HAVE THE VIRUS,
CAN SPREAD THE DISEASE ARE MOST
INFECTIOUS AND THEN GO ON TO
DEVELOP SYMPTOMS.
SO WE HAVE TO BE VERY CAREFUL
WHEN PEOPLE DON’T HAVE SYMPTOMS
AND GO OUT WITH A MASK, MAKE
SURE THAT YOU’RE STAYING 6 FEET
AWAY, BECAUSE YOU COULD HAVE THE
VIRUS, YOU DON’T KNOW YET.
AND YOU COULD DEVELOP SYMPTOMS.
AND THAT IS A KEY PROBLEM.
IT WAS A VERY CONFUSING
STATEMENT.
TRUE ASYMPTOMATIC PEOPLE WHO
YOU’LL KNOW AFTER TWO WEEKS,
YES, THEY MAY BE AT LOW LEVEL.
BUT BY THE WAY THE W.H.O.
STATEMENT DOESN’T SHOW THEY’RE
AT LOW LEVEL.
THEY SHOW THEY SPREAD FROM 0% TO
14% DEPENDING ON THE STUDY.
I THINK THAT WAS A VERY
CONFUSING AND UNHELPFUL
STATEMENT THE WAY SHE SAID IT.
AND I THINK SHE IS RIGHT THAT
CONTACT TRACING CAN REDUCE THE
SPREAD, BUT, YOU KNOW, YOU’VE
GOT TO BE A LITTLE MORE PRECISE
IF YOU’RE GOING TO MAKE A MAJOR
STATEMENT TO THE ENTIRE WORLD
ABOUT HOW THIS DISEASE IS BEING
SPREAD.
>> DR. CAMPBELL, I THINK THIS IS
ONE OF THE MANY MOMENTS THAT
AMERICANS HAVE HAD OVER THE LAST
FOUR MONTHS WHERE THEY’VE GONE,
WAIT A MINUTE, WHAT?
WHAT DOES THIS MEAN FOR ME?
WHERE DO I GO WITH THIS
INFORMATION?
ASYMPTOMATIC VERSUS
PRE-SYMPTOMATIC, WHAT DOES THAT
MEAN AND WHAT ARE OUR
IMPLICATIONS TO GO OUT AND
RESUME OUR BUSINESSES AND LIVES
AGAIN?
>> IT HAS NOTHING TO DO WITH
GOING BACK OUT AND RESUMING OUR
LIVES OR ANY CHANGE, I SHOULD
SAY.
WHEN WE SPEAK OF
PRE-SYMPTOMATIC, IT IS AS IF WE
NEED TO BE CLAIRVOYANT AND KNOW
THAT THOSE INDIVIDUALS WILL
EVENTUALLY DEVELOP THE SYMPTOMS
OF COVID-19, THE MOST WELL KNOWN
ONES AND THE SEVERE ONES ARE
COUGH, FEVER, SHORTNESS OF
BREATH.
YOU DON’T KNOW, I DON’T KNOW,
WHETHER TODAY I MAY BE IN THE
BEGINNING STAGES OF HAVING
COVID-19, NOT KNOW IT, AND BE
VERY CONTAGIOUS AS DR. EMMANUEL
SAYS.
THOSE ARE PRE-SYMPTOMATIC
INDIVIDUALS.
THOSE THAT ARE ASYMPTOMATIC MAY
HAVE THE DISEASE IN THEM, THE
VIRUS FLOATING THROUGH THEIR
SYSTEM AND NEVER DEVELOP
ANYTHING OTHER THAN PERHAPS MILD
SYMPTOMS.
SO THE DISTINCTION BETWEEN TRUE
ASYMPTOMATIC AND THOSE THAT ARE
PRE-SYMPTOMATIC AND GOING TO GET
SICK IS KEY.
AND THE SPEAKER WAS MAKING A
POINT EARLY IN THIS PROCESS OF
IDENTIFYING THIS INFORMATION,
AND IT WAS USEFUL, BUT IT WAS
VERY CONFUSING.
I THINK ALL OF US HAD TO WATCH
HER REPORTING A FEW TIMES AND
THEN READ THE WORLD HEALTH
ORGANIZATION STATEMENT TO TRY TO
FIGURE OUT AND PARSE OUT THE
DISTINCTION SHE WAS TELLING US.
IT WAS IMPORTANT THAT SHE WAS
STRESSING OVER AND OVER AGAIN,
THAT MASSIVE TESTING OF THOSE
WITH SYMPTOMS IS GOING TO BE THE
MOST VALUABLE TO IDENTIFYING
THOSE THAT ARE LIKELY TO BECOME
SECONDARILY INFECTED.
SO IT WAS JUST A LITTLE SNIPPET
OF INFORMATION THAT GOT US ALL
IN A TIZZY YESTERDAY BUT IT
CLEARLY WASN’T THE INTENTION.
THERE WAS SOMETHING THAT WASN’T
SPOKEN AND DR. EMMANUEL YOU MAY
WANT TO SPEAK TO THIS, SEE IF I
HAVE IT RIGHT.
IT’S THE VIRAL LOAD THAT ALSO
HAS SOME RELATIONSHIP TO HOW
CONTAGIOUS OR INIF HE CANNIVE
YOU ARE.
WE KNOW RIGHT BEFORE YOU BECOME
VERY SICK WITH A FEVER AND
COUGH, THE DAY YOU’RE GOING TO
BECOME SICK WITH COVID-19 YOU’RE
VERY CONTAGIOUS, YOU HAVE A LOT
OF VIRUS BEING SHED FROM YOUR
RESPIRATORY SYSTEM AND IF THE
VIRAL LOAD TURNS OUT TO BE
HIGHER IN THOSE THAT ARE VERY
SICK AND LOWER IN THOSE THAT ARE
