Joey (Host): It's an annual concern, so we're discussing
respiratory illness season.
Our guest is Dr.
William Chasnoff.
He's an internal medicine and infectious disease physician as well as as Senior
Vice President and Chief Health Systems Design officer for BB Healthcare.
This is the BB Healthcare podcast.
Thanks for joining us.
I am Joey Wahler.
Hi, doctor.
Welcome.
William Chasanov, DO: Hi Joey.
How are you?
Joey (Host): I'm good yourself.
William Chasanov, DO: I'm doing great.
Thank you.
Joey (Host): Excellent.
Well, we want to help as many people as possible to also do great
during this cold and flu season.
So to get us started, what exactly does respiratory illness season mean to
you, and when does it typically occur?
William Chasanov, DO: respiratory season is when we start to see
an increase in the number of.
Those of us that unfortunately get sick from respiratory illness, especially
viruses around where we are right now in January, for instance, this time of
the year, normally we start to see this in the United States around October
and generally runs through April.
we really look to see how many people start to get sick from what
we all know as the flu or COVID or some other respiratory viruses.
Joey (Host): Gotcha.
So let's differentiate with each of the most common such illnesses.
Let's start with the flu.
What are the, common symptoms there?
William Chasanov, DO: Yeah, so most people with a flu end up having fever.
I think it's really important, Joey, to just state that what
I'm saying are common symptoms.
Not everyone may have these symptoms, even though they may be common.
so fever is one of the most common, complaints that people have.
Body ACHE's, which is what we also call as myalgia.
people will generally develop a cough.
They can have trouble breathing as well.
And then.
What we would also expect some nose congestion, stuffiness,
sometimes a sore throat.
Those are generally the common symptoms that we see with the flu.
Sometimes people do end up getting an upset stomach.
sometimes people end up with nausea, and occasionally, throwing up as well.
Joey (Host): Then there's RSV, which if you could first remind us,
what does that stand for Actually?
William Chasanov, DO: Yeah, thank you So, It is a mouthful, but it
stands for Respiratory Sensual Virus.
And we, do acronym that as RSV to make it easier for
Joey (Host): What a great idea by whoever came up with that.
William Chasanov, DO: very much so.
Joey (Host): And so what are the typical signs of that?
William Chasanov, DO: as you're gonna see, there's a theme here, Joey,
RSV or Respiratory Sensual Virus.
Tends to be more of respiratory symptoms, but as we just talked about, those
symptoms could match similar to the flu, meaning congestion of the nose.
Stuffy nose could be also, trouble breathing.
Cough could also be fevers as well, which makes it sometimes very difficult
to determine in the two viruses we've talked about being the flu or influenza
and RSV to determine which is which.
Joey (Host): Alright.
Then of course we have COVID.
19.
How prevalent have you seen it to be so far this year?
William Chasanov, DO: COVID is still around.
this year in particular, we are seeing more of the flu, more of
the flu than we are for COVID.
We are still seeing some RSV in the area as well.
Joey (Host): And so what are the real distinguishing factors for COVID for
those who maybe haven't had to deal with it for a while and have forgotten
from back when it was far more common?
William Chasanov, DO: Well, when COVID first hit the scenes And we were all
trying to understand what this new virus.
Is, was continues to be.
Joey, it's interesting because some of the hallmark features of COVID
that seemed to not be as prevalent as they were, if you remember, was
a loss of sense of taste and smell.
With the strains changing through COVID throughout the years and
throughout the seasons, that tends to be a symptom, That is less common.
But if that does occur in the symptoms such as the stuffy nose, the fevers,
shortness of breath, that could be a hallmark feature of COVID-19.
Some of the other things that we have identified with COVID and again.
Maybe not as common as they used to be.
some people did develop rashes with CID, while you could develop a rash with RSV
And also with flu or influenza, it seemed to be at a higher chance of having that
happen with COVID, although that's also decreased with time headaches could
happen in actually all three of those viruses that we've just talked about.
Still tend to, correlate a little bit more with COVID than the other two.
So you can see that it's very hard sometimes, even as a, infectious disease
physician, as a nurse, as someone, who is taking care of individuals
to know is this flu that I'm dealing with, is this RSV, is this COVID?
Or there are other viruses that are less commonly talked about that could cause
some of those similar symptoms as well.
Joey (Host): Understood.
So speaking of COVID, has it changed the way you and yours think about or
even address respiratory illness season?
Anything that's changed on your end year to year?
William Chasanov, DO: COVID has changed a few things.
COVID has changed a few things for all of us, and BB Healthcare is in Sussex County,
which is one of the counties in Delaware.
I know that you are aware that, Joey and other's.
But I would state that beyond just Sussex County, Delaware, I think
COVID has changed several things of how we, manage, respiratory virus.
And I'll be very specific around what I mean for that.
One of those things is that COVID does for the right people, it does
have some treatment opportunities.
for instance, RSV has more limited treatment opportunities for medication.
I mean, And we know that the flu virus, if caught early enough, and
medication is started soon enough, may actually decrease the, length of
someone having symptoms with the flu.
So COVID has reminded us that.
Some of these respiratory illnesses we do have treatments for, And that it is
important in the right circumstance too.
Maybe not just wait at home and eat your chicken noodle soup and try
to, have your hot tea and be in bed.
it may be worth reaching out to your healthcare physician or provider to see if
there's something else that can be done.
I think another way that COVID has changed how we look at respiratory illness
season is through the surveillance, methods that we look to see if
quote we are in respiratory season.
And what I mean by that.
Have numbers increased of those who are sick with either the flu or COVID or RSV
or some of those other unnamed illnesses or viruses that we've mentioned before.
we know that as the Centers for Disease Control in state public health
agencies continue to survey to say.
There's more flu cases now.
There's more COVID cases.
Now.
There's also a, I will say unglamorous surveillance
called wastewater surveillance.
That has become more of the standard, not just in Delaware or in Sussex County, but
throughout our country, to also tell us if it looks like the incidence of respiratory
illness is starting to increase.
And if I can be more specific Joey, and understand that there
are listeners that I do not want to have turned off from the podcast.
but we're talking about sewage water and surveillance from, areas
that may not have been a priority.
Surveillance before COVID.
Joey (Host): All right, so that's all part of how This is tracked so that you
have an idea of where things stand in terms of where the season begins and ends.
And during.
That particular season.
How about the numbers for those that will experience some sort
of a respiratory illness, doctor?
And are there any trends this year, be it locally or nationally?
What are you seeing so far?
William Chasanov, DO: Yeah, it's a great question.
I think it's also important, Joey, if I may, to say that some of
these viruses are actually, under closer surveillance than other's.
So what I mean by That is.
While COVID-19, which may seem like an eternity ago, but was really just a
few years ago, had its own surveillance tracking through public health agencies.
The Center for Disease Control Academic Centers were tracking the number, of
those who were unfortunately infected with COVID-19 or passed away from it.
The same thing happens for the flu.
RSV and some of the other viruses.
we don't have as much data around, and I think that that's important.
So we basically use the trends of flu or influenza in order
to determine when respiratory season starts and when that ends.
So some of the trends that we're seeing, We know that the Center
for Disease Control always puts out a map in surveillance data
on a weekly basis for the flu.
I believe it's actually called Flu View, and anyone has access to that information.
It is not only infectious disease physicians or epidemiologists, anyone
should be able to go on through that site and look at those trends.
we saw that the United States, is having a moderate to severe flu season.
It also appears that.
About two weeks ago, we may have peaked from the incidence of flu for the
nation, so for the whole United States.
But here in Delaware we are a bit behind And we are still having, a
high incidence of flu in other respiratory illnesses as well.
So I think that's an important point that even though it appears that
the United States, the numbers are starting to trend down different.
Regions and geographies may not be trending down.
And right now, as of January 22nd, Delaware is not one of those.
Joey (Host): And picking up on that doctor, what factors influence
whether a season is mild or severe?
William Chasanov, DO: Yeah, I, I actually think of three main factors,
although there are several other factors.
The one is the virus itself.
what strain of the viruses are in circulation at the time?
certain strains of viruses are more contagious than other's.
That is just the life, of a virus and how it continues to adapt to its environment.
number two.
I would say would be the climate.
We know that when it's cold outside And we have a colder, season, especially this
time of the year, most of us are inside.
Most of us tend to congregate more inside than in the summertime where
we may be, out riding the bike or, or walking and, and outside more.
there's also some literature that supports that respiratory viruses are more stable.
They actually are more hearty, in the cold environment than in
the warmer environments as well.
And then one of the other important factors are vaccines.
and vaccinations are not all equal and they're not foolproof.
so for instance, The most common circulating strain of the flu virus
right now in this part of our season, which some have quote dubbed super
flu, if you have heard that, is a strain that, is in the flu vaccine,
but it is not specific for that strain.
So the flu vaccine tends to be less effective this year than some of the
other years where the flu vaccine, is out.
Joey (Host): Couple of other things.
As an infectious disease physician, what role from your experience do vaccines
play in the prevalence of disease?
Spread And the severity of illness.
And what role does BB play, would you say, in monitoring and responding to that?
William Chasanov, DO: Vaccines are extremely important.
They're important for an individual, to protect themselves against, for
instance, the flu, if appropriate, because not everyone is eligible for an
RSV vaccine for RSV, And also for COVID.
I also wanna state that as an individual, it is important to assess
if there's a benefit to receive those vaccines for one, right?
So should I have the flu vaccine this year?
Should I have, and do I qualify for an RSV vaccine this year?
Same thing for COVID.
The more individuals in our community that are able to obtain and qualify
for those vaccines or are eligible for those vaccines, there is
something called herd immunity.
And what I mean by That is.
As an individual, I get a vaccine to protect myself.
But as more and more individuals in the community get a vaccine,
we protect the entire community.
We can potentially stop in this case, serious respiratory
illness from spreading further.
And from actually, Developing complications from these illnesses
or to stop individuals from getting as ill as they possibly could have
if they had not received the vaccine.
Joey (Host): And finally, in summary here, what would you say is the most
important thing for our audience to know about fighting these illnesses in season?
If they had to keep one thing in mind, what should it be?
William Chasanov, DO: So make sure that you are taking care of yourself and you
are seeking the help that you may need.
It is also important to realize that no matter what virus we just talked
about, Joey, they are all contagious, some more contagious than other's, but
they are all contagious by, coughing and sneezing, which unfortunately
the virus And the illness it causes.
Makes people do so, wash your hands if need be.
Try to stay away from other's if you're very sick.
And if you need to seek attention, please seek healthcare attention by your primary
care physician through a walk-in center or an emergency department, in order
to make sure that you are taken care of and you know all your treatment options.
Joey (Host): great advice indeed.
Well folks, we trust you are now more familiar with respiratory illness season.
Dr.
Chasnoff, keep up all your great work.
Stay healthy and ' thanks so much.
Again,
William Chasanov, DO: Thank you, Joey.
It's been a pleasure.
Joey (Host): same here.
