  • >> Thank you for joining us today.

  • For this briefing to update you on CDC's COVID-19

  • response.

  • We are joined by Dr. Nancy Messonnier, director of

  • CDC's director of National Center for Immunizations and

  • Respiratory Diseases, who will take it over for

  • questions.

  • >> Thank you for the all of CDC's partners for joining

  • us today.

  • I want to explain a change in how we will be reporting

  • our confirmed cases of COVID-19 beginning today and

  • going forward.

  • Specifically we are breaking our case counts into two

  • separate tables.

  • One only tracks people retained by the state

  • department, and the other tracks all other cases

  • through the public healths network.

  • Candidate will continue to update the number CDC will

  • continue to update the numbers every Monday, Wednesday,

  • and Friday.

  • We don't believe the numbers represent what's happening

  • in the community -- as of this morning when you break

  • things up this way, we have 13 U.S. confirmed cases,

  • and 21 infected people when were repatriated.

  • The 21 number includes 18 passengers from the ship --

  • as of yesterday, February 20th, nearly all those who

  • are returned from woo Hahn, China, via state department

  • chartered flight have completed their 14-day quarantine

  • at 4 Department of Defense installations across the

  • U.S. We are truly thankful for those released from

  • quarantine, and wish them well as they return home.

  • As well I would like to thank the men and women on all

  • of the DOD bases and their families.

  • Also would like to thank the Travis Air Force base and

  • joint base San Antonio lackland that have continued to

  • open their doors to the recently returned passengers

  • from there diamond princess cruise ship.

  • In terms of the diamond princess earlier this week 329

  • U.S. citizens returned to the United States aboard two

  • state department chartered flights.

  • So far 18 have tested positive at CDC, there are an

  • additional 10 travelers who tested positive in Japan.

  • Multiple of these patients are receiving care at the

  • hospitals around the bases.

  • Because the passengers on the diamond princess were in

  • close setting we had a significant risk of spread of

  • COVID-19 they are considered at a high risk for

  • infection, and we do expect to see additional cases

  • among the passengers.

  • Also, since many of these passengers are over the age

  • of 60, we're prepared for other medical issues to rise

  • that will require hospitalization.

  • We're going to do everything we can to make their

  • quarantine as easy as possible, while monitoring them

  • to see if they develop illness.

  • Our goal for those people who have been repatriated is

  • to be sure each person is properly cared for and those

  • who need medical care receive it.

  • To ensure this we're working closely with local

  • hospitals and other facilities around the country who

  • are prepared to provide this care.

  • Despite the increase in cases in China, we believe the

  • aggressive travel precautions are working.

  • As I said the number of cases detected through regular

  • U.S. surveillance system as of this morning has

  • increased by 1 to 13.

  • The most recent patient was announced last night by

  • California.

  • The fact we have been able to keep this number low is

  • good news.

  • Especially giving what we're seeing among some

  • countries in Asia that are beginning to experience

  • community threats.

  • This is when cases are detected in the community but

  • it's not known what the source of the infection was.

  • This is being reported from Singapore, south Korea,

  • Taiwan, Thailand, and Vietnam, as well as Hong Kong and

  • Japan.

  • The last countries were issued level 1 travel notices

  • for earlier this week.

  • We're working in close coordination with the state

  • department to keep travelers informed with up to the

  • minute guidance including cruise ship travel.

  • And I would let you know as of late yesterday the state

  • department did post new guidance about cruise ship

  • travel for Americans that guidance is also posted now

  • on the CDC's travel website.

  • We never thought we would detect every passenger

  • returning from China.

  • Given the way it's spreading that would be impossible.

  • We're not seeing it in communities in the United

  • States.

  • It is passage, it will happen at some point in the

  • future.

  • Our goal continues to be slowing the introduction of

  • the virus into the U.S. Dethis buys us more time to

  • prepare our communities for more cases and possibly

  • community spread.

  • The new virus represents a tremendous public health

  • threat.

  • We don't have a vaccine for this novel virus, nor do we

  • have a medication to treat it simply.

  • We are now taking and will continue to take

  • unprecedented aggressive action to reduce the impact

  • this virus will have on communities in the United

  • States.

  • We are working with state, local, and territorial

  • health departments to public health workforce to

  • respond to local case, and the possibility of this

  • outbreak could become an epidemic, or can working

  • closely with healthcare systems across the country to

  • reinforce infection control principles,erse and plan

  • for surges of people seeking and requiring care.

  • Collaborating with supply chain partners to understand

  • what medical supplies are needed and available.

  • This will help CDC when we made need to take more

  • aggressive measures to ensure healthcare workers on the

  • front lines have access to the supplies they need.

  • We're working with business said, hospitals,

  • pharmacies, clinicians, manufacturers and distributors

  • to communicate about the measures and what they can do

  • to get ready.

  • I wanted to direct everyone to information on CDC's

  • website that provides guidance around community

  • mitigation.

  • The guidance that we're pointing to right now is in

  • MMWR on community mitigation guidelines to prevent

  • endemic influenza in the United States 2017.

  • But we're reviewing all of our pandemic materials and

  • updating them to reflect novel coronavirus.

  • These materials were a blueprint for the community

  • prevention we'll use in the United States.

  • If you're watching the news you'll hear about schools

  • shutting down and businesses closing in Asia to reduce

  • the spread of the virus.

  • The day may come when we will need to complement such

  • measures in the U.S. Bay next week we expect to be

  • posting a new web page focused on what the CDC is

  • already doing to mitigate transmission to community.

  • We recognize the uncertainty of the current situation,

  • as always, CDC public health experts strive to make the

  • best recommendations based on the most up to date data.

  • Our guidance will change as we learn more about this

  • virus.

  • When that happens we will share it with you.

  • I'll be happy to take some questions.

  • >> Thank you Dr. Nancy Messonnier.

  • We are taking questions now.

  • Our first question -- what is known about pregnant

  • females and COVID-19 effect on the mother and the

  • child?

  • >> So the concern here is whether or not there is

  • interuterine infection that is confused by transmission

  • from women to unborn babies.

  • There is one recent published article in the land --

  • but in the article there is no evidence of interuterine

  • infection.

  • Now pregnant women experience immunlogical and

  • physiological changes that may make them more at risk,

  • for morbidity and mortality.

  • Right now we have no evidence that the virus is

  • spreading among persons in the United States, in the

  • community, and the risk to general public is low.

  • However pregnant women, should as always, engage in

  • usual preventative actions to avoid infections like

  • washing their hands, covering their cough and avoiding

  • people who are sick.

  • >> The next question is there a timeline as of yet for

  • a peak and disease spread?

  • >> That's a really important question.

  • Right now, we don't have a clear answer for long the

  • outbreak will last in other countries or the U.S.

  • because it's dependent on many things.

  • We are looking closely at the extent of the over

  • throughout China and especially in we Hahn, we're

  • looking at the impact in traveling restrictions, the

  • sustained transmission occurring in other countries but

  • there are uncertainties about this virus.

  • We have to remember that this virus was only first

  • discovered in the beginning of January and still we are

  • in the early days of learning.

  • Now, in the United States there are a number of

  • mathematical modelers that are all working together as

  • they have for many years around infectious disease

  • modeling.

  • This group has been convened with the CDC for work that

  • we've done in the past with influenza, and we're

  • leaning on them now looking at the same data but

  • looking at it differently to try to make predictions

  • how this will rollout in the U.S.

  • I think it is not clear yet that we can be concrete.

  • All we should be saying is we do expect additional

  • cases in the United States, and that the window of time

  • we have thought border measures that slow the spread

  • down we need to use that time well to prepare better.

  • >> The next question when do we expect the travel ban

  • to be lifted?

  • I am hearing that delta is planning to start flights in

  • March.

  • >> Yeah, at this point CDC is continually assessing the

  • situation.

  • And the travel notices are as you know a level 3 travel

  • advisory to China.

  • Level 1 watch travel advisory for Hong Kong and Japan,

  • that is travelers to Hong Kong and other countries

  • should practice usual precautions.

  • We are everyday looking at the global data on where the

  • disease disease is spreading to make sure we are as up

  • to date as possible and our travel notices and working

  • closely with the state department to coincide with

  • them.

  • I understand that delta has made projections, but at

  • this point it is premature for CDC to make predictions

  • as to when the travel bans will be lifted, what we need

  • to focus on now is to continuing to try to slow down

  • the spread of the disease into the United States.

  • >> The next question, a little bitlong.

  • Request Dr. Nancy Messonnier comment on recent article

  • in journal of hospital infection, stating that how many

  • coronavirus such as acute respiratory syndrome, SARS,

  • Middle East respiratory syndrome, or endemic

  • coronaviruses can per ore persist on plastic metal or

  • glass for unto nine days but can be enact vade with

  • surface disinfectant measures.

  • Or within one minute.

  • Other biosidle agents such as .05-.2% benzyl chloride.

  • Or .02% -- are less effective.

  • This hard service survivability information is quite

  • different from most medical advisories have been saying

  • that virus sufferings for only a matter of survives for

  • only a matter of hours off host.

  • >> So the article this is referring to provides a

  • review of 22 separate studies that looked at

  • servability of SARS, MERS, or endemic Corona viruses on

  • surfaces.

  • Each of the studies only looks at different data points

  • not broadly across all the strains or all the

  • possibilities.

  • So, what I would say based on that is even in that

  • data, the virus doesn't seem to survive long on paper.

  • And so one question related to this data is a question

  • of whether packages coming from China are at risk and

  • we continue to believe that's a low risk.

  • A separate question is does the survivability on

  • surfaces, tell us anything about the transmission of

  • the virus.

  • What I would say about that is what the experiments

  • look at is truly whether it is existing on surfaces or

  • not, what it doesn't tell you is whether the virus

  • that's on those surfaces is a risk to the humans in the

  • environment.

  • We obviously want to know that question for SARS, and

  • MERS, but we simply want to know it for the novel

  • coronavirus, and there are studies ongoing to look at

  • the servability, for the new coronavirus.

  • But we are looking every day at the global data to try

  • to determine if it tells us anything about transmission

  • participants.

  • At this point based on what we know about this novel

  • coronavirus, the data says the majority of transmission

  • is occurring through respiratory transmission, as more

  • data is available clearly we'll be updating you on

  • that.

  • >> Next question we have had employees asking if it is

  • safe to travel within the United States via air travel

  • with the coronavirus status.

  • While the coronavirus is not here in the U.S. in large

  • proportions yet, is it safe to air travel?

  • What precautions should an air traveler take right now?

  • >> You think for this question you would think it's an

  • important one.

  • Right now you think there are no reason for people to

  • change their travel plans unless they are traveling to

  • China which again we have a level 3 travel notice or to

  • Hong Kong and Japan where they should be aware and

  • looking at practicing usual precautions.

  • And as I said, there are new recommendations from the

  • state department we are advised by CDC about travel on

  • cruise ships.

  • For air travel at this point we don't recommend anybody

  • else change their plans.

  • In terms of precautionary measures the things we would

  • recommend are the things we always ask in best practice

  • for people to do, especially when traveling.

  • You should avoid close contact with people who are

  • sick.

  • Avoid touching your eyes nose and mouth with unwashed

  • hands, and you should wash your hands frequently.

  • Those are the kind of things you should always be doing

  • to prevent the risk of getting infectious diseases

  • while traveling.

  • Next question.

  • It would be interesting to understand the general

  • audience to the private sector around the following

  • scenarios.

  • If there is a suspected or confirmed case in the

  • office, on the share floor of a corporate office,

  • within the building of a corporate office considering

  • community utilities, elevators, thorough fares and

  • HVAC, within a staff member's residential building,

  • assuming they live in an apartment.

  • >> Yeah thanks, right now in the United States there is

  • no evidence of transmission.

  • But in this window of time that we have, by slowing the

  • spread of the virus this is the time we're asking all

  • of our partners, including private sector business

  • partners to look at their own policies and guidances

  • for infectious diseases so that if we do have community

  • spread in the United States already you don't want to

  • be trying to find out these specific issues when the

  • first case occurs.

  • You want to know ahead of time and what you would be

  • doing.

  • So far, for this virus, it's thought to spread namely

  • person-to-person, from respiratory routes with people

  • who are in close contact, via respiratory droplets when

  • the affected person coughs or sneezes.

  • So surfaces are not thought to be the main mode of

  • transmission.

  • But if you have a patient who is ill we would suggest

  • that you actively encourage sick employees to stay at

  • home, and simply look at your sick leave policies to

  • make sure that they're flexible and consistent with

  • public health guidance.

  • You want separatish --ia want to be able to separate

  • the employees, those with cough or shortness of breath,

  • and emphasizes the importance of respiratory etiquette

  • and hand hygiene for all employees.

  • And of course you should be performing routine

  • environmental cleaning as you heard from the previous

  • question, we know a bit about what kind of cleaning is

  • effective on service surfaces for viruses like this,

  • and those are basic routine cleaning of touch surfaces.

  • Those are the kind of policies and procedures that we

  • would really suggest all businesses pull out and make

  • sure are up-to-date in preparation for the potential

  • for cases more broadly in the United States.

  • >> Thank you.

  • Next question to community acquired bacterial

  • co-infections, EG, secondary bacterial infections

  • contribute to morbidity/mortality of COVID-19 patients.

  • >> I think the premise for the question is that we know

  • from the influenza that bacterial co infections with

  • patients with influenza can do more serious -- and

  • cause morbidity and mortality associated with

  • influenza.

  • So the question is are we seeing the same thing with

  • COVID-19.

  • In the United States we haven't seen any such

  • co-infection, I think it would be a mistake to talk

  • more globally being that we haven't seen it yet.

  • I think it is certainly a possibility, but there is no

  • direct evidence yet as this is a major risk factor.

  • >> Next question.

  • Do hospital acquired bacterial infections contribute to

  • morbidity mortality of COVID-19 patients?

  • >> Yeah, so I don't know again back to the previous

  • question, I don't know that there is any specific

  • substantive data about bacterial co-infections, either

  • hospital acquired or non-hospital acquired associated

  • with coved.

  • There have been unpublished reports of hospital

  • acquired bacterial infections, in critically ilCOVID-19

  • patients, but that is still not validated.

  • I think these are important hypotheses and in the

  • United States, very important for us to maintain

  • impeccable infection control on any U.S. patient, and

  • certainly protect presentation of hospital-acquired

  • infections is a priority for our day-to-daycare and

  • certainly would be a priority for COVID-19 patients.

  • >> Next question, how has the criteria for counting

  • cases changed in China?

  • It changed last week, and we saw the increase in the

  • daily increase.

  • And now it has changed back again to the prior way of

  • counting the cases.

  • >> Yeah, there have been several changes in the way

  • China reported their case.

  • Simply there was a change where they included clinical

  • confirmation without laboratory confirmation, and that

  • met the criteria for a case later this week, that

  • criteria seemed to go back.

  • It does make it a little difficult to look at the

  • trajectory of cases in China, and at CDC we're

  • carefully vaulting the data to make sure we understand

  • if cases are rising at the same rate they had been

  • previously.

  • >> The next question, my colleague heard that CDC was

  • holding a lot of country -- is there different relevant

  • messages in these calls?

  • >>

  • >> I'm not sure I understand this question but we hold

  • a variety of calls with a variety of partners inside

  • and outside the United States.

  • And outside the United States we're holding calls of

  • multiple countries and with multiple of the CDC staff

  • that are embedded in countries as you know, CDC staff

  • has worked for many years in a variety of countries

  • around the globe on a variety of issues including

  • global health security preparedness for those

  • countries, for exactly those kind of events.

  • And the kind of situational awareness and preparedinize

  • information we're providing to you is the same

  • discussion we're having with our CDC staff in countries

  • as well as with the world health organization and

  • country as around the world and globally everyone tries

  • to institute measures to enhance surveillance, control

  • the -- and prepare for potential additional cases.

  • >> Next question, should companies communicate about

  • the virus and its spread?

  • What do you recommend organizations focus on?

  • Should companies be reviewing their sick leave

  • policies?

  • >> So as I said before it's really important the

  • interval of time we have given ourselves that we spend

  • the time well and I would encourage companies to always

  • communicate with their employees, and to look at the

  • CDC's website when we have specific guidance for the

  • private sector and use this opportunity to make sure

  • their company guidance is up to date.

  • >> Next question.

  • Have you suspended business travel to, from, the

  • affected region.

  • Some companies are requiring employees to work from

  • home for a period.

  • Is this advisable?

  • >> As I said before, we have specific CDC guidance on

  • our travel restrictions and those are up on our

  • website, and they wouldn't change, and I would referria

  • to the CDC website where we are very thorough in

  • assessing the risk and also the state department

  • website where they similarly have guidance on travel

  • and where we think Americans including business people

  • should -- what consideration they should give to their

  • travel.

  • >> Thank you Dr., and thank you to all of our partners

  • for calling in today.

  • Please check CDC 2019, COVID-19 website for the latest

  • updates on CDC's response efforts.

  • If you have further questions, please email, EOC event

  • 337 at CDC.GOV.

  • Thank you.

>> Thank you for joining us today.
