It looks like most folks have joined

So thank you again for all of you for joining

us for our virtual media availability today

Um we will uh start with brief opening remarks from

um Carl Williams and Kimberly Clement and then we will

open it up to questions

So please hold all questions till the end

You're welcome to either raise your hand or uh put

your questions in the chat box and we will do

our best to get to as many as we can

in the short time we have available

We are recording um the uh recording of this availability

will be available afterwards if you would like it

Um so we with that we'll go ahead and start

with our opening remarks

Hi everybody

Uh thanks for joining

My name is Carl Williams

I'm the state public health veterinarian in the communicable Disease

branch of the Division of Public Health

And uh again I appreciate you being here

So we're here to talk about the cluster of junta

virus cases that was initially reported by the World Health

Organization associated with travel on a cruise ship

Uh what we know about this is that there are

Uh patients that have become infected with Andes virus which

is a particular type of junta virus that is unique

to Argentina

People have become sick uh and 3 people have died

none of them have been Americans

The most recent update from the World Health Organization is

from May 8th and you can find detailed information about

the outbreak there

And there were Americans on the ship that have been

uh repatriated back to Nebraska which is where they remain

except for two that have gone on to Emory University

So there are about 17 Americans that are still in

Nebraska and being assessed and they may remain there or

they may

Actually come home to their home states and we are

still in communication with our federal partners on that to

determine exactly what's going to happen uh but that is

kind of the status of the situation at the moment

And I think we'd be happy to take any questions

that you have unless uh Yeah and we just start

there

Yeah thank you Carl

So um whoever has questions you're welcome to either put

it in the chat or uh raise your hand and

we will go one at a time

Hi can you hear me Yes go ahead Lucy

Hey so um right now I think we're just kind

of wanting to know is this kind of a concern

that North Carolinians need to be uh focused on right

now I think that there's a lot of misconception um

as far as how uh dangerous it might be to

the public right now

Sure

I think a little bit of perspective and background on

these viruses might help

Uh these are not new viruses

So you may or may not remember the original outbreak

of hantaviruss pulmonary syndrome in 1993 in the Western United

States in the Four Corners region

That was caused by a particular junta virus called Sin

Nombre virus and it did uh cause a large number

of cases including fatalities

Um so this is a disease that's likely been present

in North America for some time but most cases are

from the Western United States

It's rare to see it in the eastern United States

but what we know Because this became reportable in 1995

including in North Carolina we all the states have been

doing surveillance for Hunta virus since then

We've only had one case identified in North Carolina and

that was in 1995

That was with another junta virus that we think was

Monongahela virus

There have been cases in Florida associated with Black Creek

Canal viruses and What I'm getting at here is there

are a lot of different types of hantaviruses and not

all of them occur in the United States and most

of them don't occur in North Carolina

In fact again in the Southeast it's an extremely rare

disease

These viruses also co-evolve with their rodent reservoir

So it's not like Andes virus is going to become

established in the United States

This is something that is concerning if you live in

Argentina

Or you travel there

Uh likewise if you travel to or visit the Four

Corners region or parts of California where this disease is

endemic yes it could be a concern but it's really

not something we'd Suggests that people should worry about here

in North Carolina

It's something we've known about for a long time

In fact the original outbreak of Andes virus was first

characterized in Argentina in 1996 so these are not new

viruses

Thank you

We'll go to our next question which I believe is

Anna King

Yes so really quickly um we did see that uh

there were some who were able to return home but

were not required to quarantine um as much as I

guess encouraged

Why is that And can we expect that to continue

with I think the one person who was on the

boat from North Carolina or on the cruise ship from

North Carolina

Yes our understanding is that there were some people including

some people from the United States that left the ship

early and they have returned to their home state

They did it in advance of the State Department coordinated

repatriation and you can find press release notices from California

and Virginia about this

However once the State Department became involved and the rest

of the American citizens were identified they were handled as

a group

So they were all first taken to Boffett Air Force

Base and then University of Nebraska Medical Center which is

where they all remain again except for two that were

transported onto Emory

And I don't know outside of the person who is

from North Carolina where the rest of them are from

Presumably they will those plans are being made with their

respective states

Those plans including uh quarantining or not quarantining

So the CDC is not using the word quarantine uh

but they are uh keeping them uh for a risk

assessment and clinical monitoring at Nebraska and the people are

free to stay there if they wish to

We'll go to our next question in the chat from

Patricia

She's asking if there's any additional details we can share

about the North Carolina resident

So no at this point we're not sharing any information

about the person

We'll go to our next question in the chat

Are we able to confirm if the North Carolina resident

is positive or simply being monitored in Nebraska and will

that passenger continue to be monitored there or at home

So They are being monitored in Nebraska

If they stay there they will continue to be monitored

and if they come home they would be monitored by

their respective local health department

They have not been tested as far as I know

but I would say that testing for hantav virus is

rapidly evolving new diagnostics are being developed as we speak
