Influenza: check your pulse!

This year influenza is bad. My key test in influenza is not a chest x-ray. It is taking a resting pulse and a walking pulse.

Why? Influenza can cause a walking pneumonia. Walking pneumonia is where the lungs are infected throughout and there is tissue swelling. It is different from a lobar pneumonia. In lobar pneumonia people run a higher fever, look sicker, and on the chest x-ray, that part of the lung is white: infection, not air.

In walking pneumonia, the chest x-ray may be read as normal. This is because all the lung tissue is equally swollen. The swelling means that there is less air space. The person may feel ok at rest. They feel exhausted when they walk because the heart must take up the slack for the missing air space, the swollen lungs. At rest this week one person’s heart rate is 84. After walking it is 124. Normal is 60-100, so 124 is like running a marathon: exhausting and hard on your heart and body.

I have patients saying “I was sick two weeks ago and I am still exhausted.” If their pulse is much over 100 after they walk, they cannot work until it comes down. If they work and wear themselves out, the lungs can’t heal. The treatment is rest. If they are at work with a pulse of 114 or 124, then they risk getting a secondary infection in already damaged lungs. They could die.

Check your pulse at home. Count the number of heartbeats in 60 seconds. That is your pulse. Walk around, sit down, and check again. That is the walking pulse. Over 100 is not normal.

This is a bad influenza. The tamiflu (oseltamivir) helps but works best in the first three days of flu. Check your pulse, be seen, rest and get well.

Random confuse the engine search

A friend and I are using Facebook to message this am and she says she hates that Facebook is mining for advertising all the time. I said we should do a random confuse the engine search every day. Something silly! I searched enamel zebra hamsters first…. And it’s fun to watch the internet try!

What silly search would you use to confuse the big data mining on the internet? Go wild! Confuse your feed!

Influenza 2016

No influenza cases so far this year in my clinic.

I watch the flu map faithfully each week, as I try to get my stubborn patients to get their influenza vaccine. It takes up to two weeks to get them immune, if it works. It works most years about 80% f the time. When it doesn’t work, it’s because either their immune system didn’t respond or because the influenza virus has traded genes enough that the guess six months before on which way it will evolve, is wrong.

Here is the CDC weekly influenza update link: http://www.cdc.gov/flu/weekly/fluactivitysurv.htm.

If you click on the FluView Weekly Influenza Surveillance Report, scroll down. My favorite to show patients are the Outpatient Illness Surveillance, which maps this year’s rise in influenza in the US each week, compared with past years. We are having a late year.

My other favorite is the next one down: ILIState Activity Indicator Map. It changes color each week by state as the influenza reports come in. Arizona turned red this year about a month ago, after Puerto Rico. Red is high activity level. The rest of the country was dark green, low, or light green, but has steadily been turning yellow green, yellow, orange…. Washington State is still green. But now only a few states are green and it’s still on the rise. If we continue to have unseasonably warm sunny days, like the last four days, we might avoid the influenza. But if it gets wet and cold again: boom. Like a sneeze, spreading. This is the first week we’ve had seven red states. I have been wearing a mask in clinic every time I see someone coughing. And I got a cold anyhow, but it is not influenza and I don’t think it’s strep A, thank goodness.

I said influenza is airborne but it isn’t. Or there is controversy. It is at least droplet spread, but sneezes count. Apparently influenza can get to people 6 feet away. Wear your space suit with the oxygen filter to the grocery store. http://www.cdc.gov/flu/about/disease/spread.htm — lots of information about the influenza virus. Is all of it 100% correct? Don’t be silly, this is science, not a religious text: science changes, just like the flu virus.

This year, a CDC alert was faxed to clinic on February 1: http://emergency.cdc.gov/han/han00387.asp. It is all very calm and clinical, with this sentence in the second paragraph: “CDC has received recent reports of severe respiratory illness among young- to middle-aged adults with H1N1pdm09 virus infection, some of whom required intensive care unit (ICU) admission; fatalities have been reported.” I called my son and said, “Get your flu shot now.” If you read the rest, it says ages 20-50 as the “young” and “middle-aged” adults. Not the group that we expect influenza to hit, but that is the group that got hit in the 1918-1919 influenza.

Get your flu shot… be careful out there.

 

I took the photograph two days ago with my phone: Boa was on my lap and I wrapped her in the shawl I’d knit, and she was so relaxed…. that’s how we need to take care of everyone with influenza.
