- And our Medical Reporter, Lorie Johnson,

joins us now again tolook at some key questions

around the Coronavirus.

So Dr. Fauci is warning that another round

of the Coronavirus is inevitable.

One problem we could have

is that the World HealthOrganization says people

who have recovered from COVID-19

actually might not be immune,

so they may get the disease again.

Why is that now?

- Well, we were hoping,Efrem, that this particular

Coronavirus, COVID-19,would be more like SARS

which was kind of aone-and-done type thing.

SARS came on the scene, scared everybody,

that's a Coronavirusvery much like COVID-19,

and a vaccine was developed for it,

everybody was ready for it to come back,

and we never saw it again, thank God.

It never came back, stillhas never come back.

And so, a lot of scientistswere hoping COVID-19

would be like that,

but now it looks likeCOVID-19 is going to be more

like the four Coronavirusesassociated with the common cold,

which we know come backevery cold and flu season.

And one of the main reasonsscientists believe that COVID-19

is going to come back in thefall is because we're now

looking at the SouthernHemisphere, Australia,

where it's now starting tobe their fall and winter,

and oftentimes whathappens this time of year

in the Southern Hemisphere,

is exactly what we see when itcomes fall and winter for us,

and sure enough COVID-19 isrearing its ugly head there.

So we have every reason to expect

that it's going to come back.

Now as far as being immuneto it when it comes back,

let's say you have COVID-19 right now,

and you have the antibodies,and scientists say,

well, that probably means you're immune,

then don't get a false sense of security

that you're gonna beimmune all the way back

in this coming November,

because we've seen with so manyCOVID, rather Coronaviruses,

that the immunity, theantibodies in our body,

only last a couple of months.

With MERS, which is another Coronavirus

which is not very many cases every year,

but we do see them inMiddle Eastern environments,

those antibodies can last up to two years,

and we know with thingslike the chicken pox

the antibodies can lastan entire lifetime,

but it looks like our antibodies for this

may or may not lastlonger than two months.

Scientists don't like to say anything

unless it's been tested,

and we really don't know right now.

So the World Health Organizationis telling countries,

whoa, whoa, whoa, tapthe brakes a little bit,

don't start issuing thesecards that say you're immune,

because your immunity might not last,

and some of the tests might be faulty.

- Another thing we were talking about,

this was at our dinner table last night,

a dog tests positive for COVID,

what precautions shouldpeople now be taking

with their animals?

- Right, now this issomething we've been wondering

since day one, is what about our pets?

And so, in Chapel Hill, NorthCarolina, the family dog,

their pet, did testpositive for Coronavirus,

and so it does look likehumans can pass it to pets

and other animals, but it looks right now,

the CDC says the chance is very low

of pets passing it to humans.

In North Carolina what happened

was the mom, the dad, and oneof the children in this family

had COVID-19 and weretaking part in a study

at Duke University, and aspart of the study they tested

the whole entire family,

and the mom said, "Hey, youknow, our pug is acting really

"weird, it's not eating,that never happens,

and it has this really weird cough."

So scientists decided totest all the family pets,

both dogs, both cats, and a lizard.

The dog came backpositive and it turns out,

they're always in its face,it eats off of their plates,

it sleeps with one of the family members,

and so the CDC did comeout with these warnings

that say if you have pets,

restrict them frominteracting with other animals

when outside, try tokeep your cats indoors,

restrict pets from interactingwith other animals,

particularly if you, trynot to go to a dog park,

try not to go to public parks

where there might be otheranimals and people there,

and also keep the dogs on a leash.

If you're sick with COVID,try to avoid interacting

with your pets, but if you do have it

and you have to interact withyour pets, then wear a mask,

and wash your hands before doing so.

It seems like it's a little over the top,

but gotta keep our critters safe,

and by the way the pugrecovered on its own.

And we did see a lion and some tigers

at the Bronx Zoo test positive,

and it looks like thatone of the zoo workers

gave the COVID-19 to them,

but all the animals are doing fine now.

- Excellent, excellent.

Let's talk about exercisein terms of helping

to prevent the Coronavirus.

What can we be doing?

- Well, it turns outthat exercise is great

for fighting the Coronavirus.

University of Virginia researchers found

that when you do exercise, itactually produces a powerful

antioxidant that fights off what's known

as Acute Respiratory Distress Syndrome,

which as you might imagine isa very serious lung disease,

and this antioxidant also protects,

not just the lungs, especially the lungs,

but also other organs,as well, with the heart.

And so, we see that somany, 99% of people who die

from COVID-19 have other problems.

And so we talked earlier aboutthis coming back in the fall,

one way to protect ourselvesfrom that second wave

that we might see in the fall,

is to start exercising, cardio exercise,

and then also weight lifting really helps.

And also, Efrem, great for mental health,

because we know a lotof people are suffering

with all kinds of mentalhealth issues, right now.

- That's why I refuse togive up working (laughs).

- Yeah!

- Yes indeed, thank you, Lorie.

- There you go.- Much appreciated.
