"Probably a combination of warmer weather and things like that, but we really do expect things to pick up and we're actually seeing signs of that around the country."
He says doctor visits for flu-like symptoms in the state are down around 50-percent from this time last year. Welch says flu activity is increasing in other parts of the country and it's only a matter of time before it hits Louisiana.
"We do expect that once it comes, probably withing the next week or two, we're going to see an increase in activity."
With the heart of flu season coming, Welch says it's not too late to get that flu shot.
"It goes to work immediately. You get full protection in about seven days. So there is still absolutely time to get that flu shot and be protected before it gets here."
