Just for example: All the hysteria about getting a flu shot this year? Great that you did, but a new strain has ALREADY mutated.

Although there are reports this new strain is showing up in as many as 20 per cent of flu viruses isolated from U.S. patients in recent weeks, Dr. Tam says its apparent spread is not cause for alarm.
"We do expect some cross protection," Tam told CTV, noting its closeness to the A/Fujian virus, which is targeted in this year's shot. "We are only mid-way through flu season ... We still recommend that people get their flu shots."
But there are some reports of vaccinated nursing staff in Ontario coming down with a flu-like illness at rates higher than should be expected.
And that suggests protection against the new strain may, in fact, be minimal.
Dr. Donald Low admits it's unknown how much protection this year's flu shot offers.
"We don't know yet just how much protection that the vaccine we provided this year is going to provide protection against this new strain."
Unfortunately, it could take until the end of flu season, likely sometime in May, before scientists will be able to provide a better answer.

And, another problem: infectious disease (nosocomial infection) is a growing problem in hospitals. Drug-resistant bacteria and virulent infections (as in norovirus, the "cruise ship virus") are hitting hospitals hard. See:

Hospital acquired infections are a leading cause of death in the U.S.. One in twenty patients can expect to get an infection that is unrelated to their condition upon admission. Consumers Union supports public disclosure of hospital-acquired infection rates so that consumers can choose the safest hospitals and hospitals will have an incentive to improve infection control efforts.

Sadly, our policy makers are too shortsighted to link environment with health. Only when their loved ones die from disease outbreaks will they realize, and by then it will be too late for all of us.
