Nebraska health officials say another person who had the H1N1 flu virus has died.

Health officials based in North Platte say a Lincoln County man in his 30's who didn't have a chronic underlying health condition has died. Because of privacy laws, officials said they can't release the man's name or other details.

His death is the 12th in the state with ties to H1N1.

The state's chief medical officer says flu activity has dropped, but urges Nebraskans to remain vigilant.

Officials say most people have been able to recover at home from the flu strain without needing medical care.

Those who have trouble breathing or experience other serious complications are advised to consult a health care provider.
