I'm on the mailing list of the Virginia Commissioner of Health, who sends me emergency notes whenever they get new information. So far, that communication link has been quiet.
This is what I know to date.
- H1N1 has been working its way around both in wintertime south of the equator, and even in the "off flu season" north of the equator. Mostly though its been making its way around in the south.
- The virus managed to make its way into a flock of turkeys in a South American country. That isn't good. Whenever a bug like this can readily jump species, it can pick up genetic material from unusual sources. So the myriad possibilities have just expanded quite a bit.
- The mortality rate by age group for seasonal flu is typically a U-shaped curve, with babies and the elderly most likely to die. The scary 1918 H1N1 was a W-shaped curve, with the healthiest having their immune systems attack the lungs. (Not good...) This H1N1 - for now - is a bit unique. It's partway in-between a U-shaped and an L-shaped curve. It seems that the elderly have some residual immunity to this due to their exposure to the 1918 H1N1, and its myriad echo waves through subsequent decades. So THIS is why the press has been making a big deal about young people being at risk. It's less about the morbidity of this H1N1, and more about the folks in the population likely to catch it.
- School is starting, and yet we're months away from the first H1N1 vaccinations becoming available. Fasten your seatbelts!
