The national count of confirmed swine flu cases rose to more than 21,000 this week. That's 3,000 more than last week. And the CDC reports the number of deaths went up from 44 to 87 this week.
Dr. Herbert DuPont directs the Center for Infectious Diseases at the UT School of Public Health. He says the numbers in and of themselves aren't alarming.
"The number of deaths is actually very small compared to a normal flu season. What's surprising is we're talking about June in Texas with hundred-degree weather and influenza — that's the shock."
That's because influenza thrives in cool, dry weather. DuPont says during the humid summertime, the virus tends to go away.
But DuPont says because of the large number of cases in Texas, people should keep their guard up.
"Kids are getting it at camps that they go to and individuals are getting exposed at school. So I think for another month, until the weather really gets hot across the country, we're going to be seeing cases of swine flu."
DuPont says you should try to maintain a distance of six feet between you and anyone who exhibits symptoms. Also cover your mouth when coughing and wash your hands frequently.
Wisconsin, Illinois and Texas have had the mostÎ¾reported cases of swine flu.
