First case of flu confirmed in the city

How do this year's numbers compare with last year's flu season, the most severe in decades, which contributed to the deaths of an estimated 80,000 people?

Officials said they are investigating the three cases.

According to the CDC website, vaccines are recommended to contain H1N1, H3N2 and Victoria lineage-all different types of influenza.

Flu viruses are classified by A, B, and C. The influenza A virus is the source of widespread infections because it can mutate much faster than the other versions and is carried by birds to humans and other animals. Overall, approximately 882 cases have been confirmed in Louisville Metro this flu season, which is up from just 179 cases confirmed at the same time in the previous flu season.

Flu is most commonly spread through close contact, coughing and sneezing.

Hu did not know how numerous people who died or were hospitalized had been vaccinated against the flu.

To help promote personal health and wellness, get an annual flu vaccine.

Despite the spike in cases, this is the typical pattern seen, and is on par with what was seen past year as well, said Khan. She was diagnosed with H1N1 and meningitis before her death.

Practicing good hand hygiene is the No. 1 precaution individuals can take to protect against the flu virus and other germs.

Flu vaccinations aren't ideal but will reduce your chances of becoming ill. This year's vaccine is well matched to the circulating strains of flu and a lot of vaccine is available, Brammer added. Seven of the largest US companies reported paying out nearly half a billion dollars because of last season's flu, according to Jason McGorman, an analyst at Bloomberg Intelligence.

Kentucky reports Louisville is one of the hardest-hit areas right now, with more than 550 confirmed cases recently and 882 cases overall this flu season. The agency gets statistics early in the new year, Hu said. He also urged those with symptoms of the virus to avoid visiting the elderly or vulnerable people while ill.
