SHOOT: Levels of infection are higher in summer than for an ordinary winter season. That's troubling; it's portentous for when winter returns.
Confirmed cases of the new H1N1 virus, known as swine flu,
in the British capital more than doubled to 1,794 yesterday from
a week earlier, the Health Protection Agency said. The pandemic
bug is transmitted more easily than seasonal flu among people
younger than 50 because no one has natural immunity against it. In England and Wales, there were 29.6 cases of flu-like
illnesses per 100,000 people last week, the college said. That
compares with 11.4 per 100,000 the previous week and 6.5 the week
before that. In the southern region, the incidence of flu-like illness
last week was about four times higher than the 10-year average
for summer, according to the college’s report. Flu typically
peaks in England in January, and the rate reported for the
southern region by the college’s flu surveillance network,
comprising 420 doctors, was the highest in five months. |
