Sacramento County health officials now confirm 24 people between the ages of 18 and 64 have died of the flu so far this season.  

Those reported to have died include 13 women and 11 men. Those reported to have died include 13 women and 11 men. 

However, some who died from H1N1 did not have underlying conditions, and were both relatively young and healthy.  

"We are concerned that young and healthy individuals are not getting vaccinated, because their demographic group is not typically severely impacted by influenza.  What is different with H1N1, compared to the other strains, is that we are seeing severe disease in young and healthy people," said Sacramento County Public Health Officer, Dr. Olivia Kasirye, in a press release. 

Ninety-eight are in hospital intensive care units.  

Last year, only 16 people died of the flu in Sacramento County.

Three strains of influenza are currently circulating in Sacramento County - H1N1 (which is a flu A strain), Influenza A and Influenza B. The good news is that the flu vaccine, which is still readily available, covers all three strains of the flu that have been detected.   

The California Department of Public Health and the Centers for Disease Control and Preventionrecommend annual influenza vaccinations for everyone six months of age and older, including pregnant women. And they say that it is not too late to get a vaccination this year.
