Influenza (Flu)
Influenza, “flu,” is a contagious respiratory illness caused by influenza viruses. Symptoms can include fever, headache, extreme tiredness, dry cough, sore throat, and muscle aches. Flu season in Los Angeles County is typically the first week of October through the end of March. However, flu circulates throughout the year. Depending on the season, age, and prior health conditions flu can be serious and/or life-threatening. Nationally, flu can cause between 9-35 million cases and on average 200,000 hospitalizations each year. The CDC estimates that anywhere from 5-20% of the population can get the flu each year. In Los Angeles County with more than 10 million residents, that means anywhere from a half a million to 2 million cases of flu can happen each season. 

Everyone 6 months of age and older should get a flu vaccine as soon as vaccine is available each fall.  Since the virus changes each year it is necessary to receive a new influenza vaccine each year.

Health Officer Order Information
In 2013, the Los Angeles County Department of Public Health and Health Officer issued an order to protect health care personnel from influenza and lower the risk of the transmission to patients. This order remains in effect. Additional information HERE.
