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.
