Welcome to Dr. David Eifrig's Health & Wealth Bulletin.
This is Weekly Update.
Right now, we're in the midst of one of the worst flu seasons on record.
In fact, about 31.5 cases out of every 100,000 hospitalizations are because of the flu.
That's one of the highest numbers that we've seen.
Unfortunately, we still have about 11 to 13 weeks left, meaning that this flu season can
get even worse.
Already, we have 30 children who have died of the flu in the U.S. and the number of adults
is still untold.
We won't really know until the end of flu season.
Now the reason the flu is so dangerous is because of how quickly it mutates.
So the flu virus comes in one of three types.
There's type A, type B, and type C. Type A is the most dangerous – that's the one that's
responsible for so many epidemics like we're seeing right now.
So that's the kind we're going to focus on today.
Now the flu virus gets its name from two proteins on the outer shell of its envelope.
There's the H protein and the N protein.
The H protein, hemagglutinin, comes in 18 different types.
The N protein, neuraminidase, comes in 11 different types.
Now these two proteins are important because they both help determine how infectious the
flu is and how quickly it can spread once it's inside your body.
The combinations of these two are why we get different strains like H1N1 or H3N2, which
is what we're seeing right now.
Now H3N2 is one of the most dangerous types out there because of how quickly it spreads
and how many complications it can bring.
Now this might also be why we're seeing such low effective rates for the vaccine.
Here in the U.S. they're estimating about a 30% effectiveness, but in places like Australia,
it's only about 10% effective.
Now, one thing to keep in mind is: don't let this dissuade you from really getting your
flu shot every year.
In fact, one study out of the Uniformed Services University of the Health Sciences demonstrated
that getting your flu shot actually lessens the severity of your symptoms.
They looked at a group of folks who had the flu, about 72% of whom were vaccinated.
Those who'd been vaccinated had a far lower chance of having a fever, they had fewer upper
respiratory problems, and overall their symptoms were far less severe.
This is very important because we want to make sure we get as much protection as we
can, even if we do get the flu.
Another point to keep in mind here is that about 80 to 85% of all children every year
who die from the flu were unvaccinated, so it's especially critical to get your flu shot
if you're a child, if you're an adult over 65, or if you're someone with a compromised
immune system because you certainly need that help fighting off the flu.
So if you're having symptoms of the flu, it's important to know if you have the flu or simply
another cold.
Remember, the cold is also a virus, so it's very similar in the way it presents.
In fact, both colds and flu give you a cough, sore throat, runny nose, body aches, headaches,
fatigue, sometimes even fever.
But it's important to remember that colds usually come with a stuffy and a runny nose
and they come over a period of time – you can feel yourself getting sick.
With the flu, the key is a very rapid onset of symptoms.
If this is the case for you, you certainly want to go to your doctor and talk to them,
especially if you're in one of these immune compromised groups.
If that's the case, your doctor may recommend antiviral medications.
These are special medicines designed to fight the flu but they're only really effective
if given within the first 48 hours.
That's why keeping an eye on your symptoms and getting help immediately is really important.
That's it for now.
