The Kentucky Department for Public Health (DPH) today reported to the Centers for Disease Control and Prevention (CDC) that the flu activity level in the state has increased to regional, the second highest level of flu activity. The activity levels for states are tracked weekly as part of the CDC’s national flu surveillance system.
Regional activity is defined by CDC as outbreaks of influenza or increases in influenza-like illness and recent laboratory confirmed influenza in at least two but fewer than half the regions of the state with recent laboratory evidence of flu in those regions. The previous activity level was sporadic, the lowest level indicating activity. Nearly all flu cases at this time are due to novel H1N1 flu (swine flu), as seasonal flu has not yet begun to circulate.
