MADISON (WKOW) -- State health officials say Wisconsin residents may not have seen the last of H1N1.
State influenza coordinator Tom Haupt says state health officials will watch closely for signs of swine flu after college students return from spring break. Haupt says the state has plenty of vaccine and officials are reviewing lessons from the past year so they can communicate better.
The state Department of Health Services confirmed more than 2,600 cases in November and December. Since then the outbreak has faded with only 112 cases confirmed between January and mid-March.
Experts caution that pandemics historically come in three waves, and a third wave of the flu has yet to strike.
