According to the CDC weekly flu report, there is barely any flu around except in the southeast (Georgia and somewhat in Alabama). Since the Southeast is often the first area in the country to report flu cases, I suspect that by January we’ll be seeing it move across the country.
This year’s flu is primarily type A (the “novel H1N1”, formerly known as “swine flu”, but more prominently AH3N2).
The currently available vaccines do “cover” the currently-circulating viruses.

For those of you who use the homeopathic nose, Influenzinum, you may start taking it, one dose weekly.
