(NBC News) -- The flu is here and it is deadly.
Reports of flu-related hospitalizations and deaths are increasing throughout the country and this year more young adults are falling ill.
From Florida to Michigan, the Northeast to Northwest, people are rolling up their sleeves as fear of catching the flu is spreading almost faster than the virus itself.
There has been a spike in cases with twenty-five states now reporting widespread flu activity.
Medical experts say the germ swap that typically occurs after winter break could contribute to even more flu.
"We may see an increase within a week because people are just being exposed to it more," said Dr. John Svenningsen of Allina West Health.
H1N1, which primarily targets young and middle-age adults has dominated this flu season.
"We are seeing people who are generally healthy in their 30s, 40s and 50s come down with very serious flu related illness and in some cases need life support," Dr. Matthew Davis of the University of Michigan Health System said.
Flu shots offer the best protection from the virus and may weaken symptoms if you still get sick.
Flu season typically peaks from January to February.
