Flu Cases on the Rise

The number of people suffering from the flu in the U.S. is almost 10 times higher than last year in some cities. In Boston, the city has declared a public health emergency and will begin offering free flu vaccinations. Health authorities said flu season usually starts in December, but began in November this year. The particular flu strain going around --H3N2 -- has a reputation for causing fairly severe illness, especially among the elderly.
