Flu cases spiking this holiday season, CDC data shows

TL;DR

Flu cases are spiking across the country, with some regions experiencing record numbers.
As of December 20, an estimated 7.5 million flu cases, 81,000 hospitalizations, and 3,100 deaths have occurred this season.
Eight flu-related pediatric deaths have been reported.
32 jurisdictions are currently reporting high or very high levels of flu activity, a significant increase from the previous week.
New York State recorded its highest weekly total of flu cases since 2004.
A new subtype of influenza A, H3N2, is spreading quickly and is responsible for a large majority of positive flu tests.
Experts suggest H3N2 has evolved slightly, making it harder for the immune system to recognize.
Fewer people have received flu shots this year compared to previous seasons.
While H3N2 may present a challenge, the flu vaccine is expected to have a good match for H1N1 and flu B.
Early data suggests that flu vaccines are still effective in preventing severe illness, particularly in children.
