Nevada County reported its first flu death of the season Friday.
Earlier in the day, the California Department of Public Health said the flu deaths are happening earlier in the season than normal. They also said those who have died have all been younger than 65 years of age.
The state agency says the H1N1 virus is similar to the one that caused an epidemic a few years ago. The strain affects people the same whether or not they have compromised immune systems or underlying health issues.
The state has only confirmed seven deaths statewide that were caused by complications from the flu, including one in Sacramento and one in San Joaquin counties.
Health officials say this flu season has been more severe than seasons past.
