RENO -- Flu cases are on the rise in Washoe County, and health officials are urging people to take precautions.
County epidemiologist Melissa Peek said January and February are typically peak flu season, although the peak has come earlier than in past years.
"It's cold outside and people are indoors more people are attending parties social gatherings," she said.
Health officials said the best way to avoid becoming sick is to get a flu shot. The shot protects against four strains of the flue, including the swine flu. Peek said swine flu is the most-common strain so far this season.
Health tips this flu season include: covering your cough, staying home when sick, getting treatment right away if sick, washing hands often and wiping down surfaces.
Nurse Practitioner Karri Fraczek works at Dr. John LeMieux's practice in Reno said she has seen an increase in both flu and respiratory illnesses.
