Influenza (Flu) Surveillance and Links
Flu Surveillance
Influenza Weekly Reports
National flu surveillance updated weekly by the Centers for Disease Control and Prevention.
The Nevada Division of Public and Behavioral Health's Office of Public Health Informatics and Epidemiology works with local health districts and departments to conduct surveillance for influenza-like illness (ILI) and monitor laboratory–confirmed cases of flu. This enables public health professionals to:
  • Identify the beginning and end of each flu season, so communities can plan and respond accordingly.
  • Monitor the level of influenza-like illness in communities to determine the extent of the flu season and variances in influenza-like illness by age.
The term influenza-like illness is used to describe people seeking medical treatment for symptoms consistent with flu infection: a fever over 100 degrees Fahrenheit, a cough and a sore throat.

The only way to absolutely determine whether a person has the flu is through a laboratory test of a culture taken by a doctor. Since most people do not seek medical treatment for the flu and cultures are only collected from a fraction of the people who see a doctor, monitoring for symptoms consistent with flu infection provides a more-accurate representation of flu virus activity.

The few cultures collected by doctors allow public health laboratories to confirm a diagnosis of influenza and determine which flu strain has infected the patient. In turn, public health agencies can gauge which strains of flu are circulating and whether they match the strains included in the flu vaccine.
