Swine flu precautions are justified, Dallas County's health director said Wednesday.
Director Zachary Thompson urged everyone to pay attention to the spreading virus, even though the number of Dallas County cases -- three -- is relatively small.
"I’m very shocked that some people think this is overkill," he said. "This is not overkill. This is serious."
School officials have closed schools -- including all of Fort Worth ISD -- where confirmed or probable cases have been reported. And officials have postponed all public high school athletic and academic competitions until May 11.
Health officials said they hope their efforts keep the outbreak from becoming more serious.
"I realize some people think the media may be overblowing this," Thompson said. "But the issue is, it’s not. It is real. We've seen one death in the state of Texas. That’s why were committed to doing the necessary work for 24-7 responding to this."
The latest news from around North Texas.
Several of Dallas County's probable cases have no connection with Mexico, according to Dr. John Carlo, county health department medical director. It adds to the mystery of how the virus is spreading in Dallas County.
Carlo said it is "really important for the individual to take the precautions and make a barrier for themselves." He recommended frequent hand washing, covering your mouth when you sneeze and keeping a clean area around you.
