35K, or 65K including (as the CDC does, other upper respiratory stuff that is flu related) is a lot, but not a huge number.
Here are the stats, per year.
Number of deaths for leading causes of death:
* Heart disease: 652,091
* Cancer: 559,312
* Stroke (cerebrovascular diseases): 143,579
* Chronic lower respiratory diseases: 130,933
* Accidents (unintentional injuries): 117,809
* Diabetes: 75,119
* Alzheimer's disease: 71,599
* Influenza/Pneumonia: 63,001
* Nephritis, nephrotic syndrome, and nephrosis: 43,901
What makes this different, and what worries people is:
a) a 30% fatality rate, striking mostly people in the 20s-30s, which is for some reason unknown, a pandemic marker. Most flu deaths in that normal 35K year to year deal is very young (babies) and very old (infirm) persons. The real killer strains target and kill the MOST HEALTHY persons in the population, as this one is doing.
b)Speed of movement. It moved very fast, no doubt at this time, its beyond control - thank airplanes for that, and in this case, Spring Break in Mexico, where most of the US cases came from.
c) swine based. There are two types of flu viruses that can make the jump from animal hosts to humans that wind up killing. One is from pigs, the other from birds (Avian flu). Like the 1918 pandemic, swine based ones tend to be worse.
d) airborne. The worst kind. Look, viruses are a long established life form on this planet. Way older than humans. And like all life forms, as Malcomb in Jurrasic Park would have it "Life finds a way." They mutate, change, evolve even. If it would cross with an avian strain, it would be very bad. Airborne viruses can live for a while outside the hosts, and that is very dangerous.
e) OK, one for the old people here. When do you get flu shots? Late fall right? Because the flu season tends to be when? Winter. January/Feb tend to be the height of the infections. This one is starting in early spring, so it could continue into summer, and again, somehow (and no one understands why) the viruses that can survive into summer tend to have the worst effects.
Its not time to panic yet, but its good to be prudent. And its nothing to pass off. Sure, we get them all the time, but when they start to rock and roll, well.
The 1918 pandemic killed some 25 million people in the first few weeks, or about the death rate for AIDS in the 25 year history of that virus.
