A measles outbreak in Kentucky has rapidly intensified, with state health officials confirming Thursday that active cases have now climbed to 25 across the commonwealth.

Dr. Daniel Blatt explained what Kentuckians should know about their risk level with hantavirus.

There are six Norton Healthcare locations currently providing the vaccine to kids, and on Thursday, the Breckinridge Lane location alone will give nearly 250 shots to kids ages 12 and up.

Norton Healthcare's Dr. Daniel Blatt says it shows that safety precautions help defend against the virus.
