CHARLOTTE, N.C. -- Across the country, there were 7,000 confirmed cases of the flu, which is double the number of cases we saw this time last year.

And here in North Carolina, we’re also seeing an outbreak of whooping cough.

“If you drink fluids, get enough sleep, exercise, generally you’re okay,” suggested one woman.

But even those of us not prone to sickness is catching the contagious flu virus.

And 13 cases of whooping cough have been reported in Henderson County.

Both illnesses easily spread through tiny droplets when people cough or sneeze. Both are potentially dangerous, especially for children and the elderly.

It’s why a doctor came up with the Sneez app, allowing local parents to track illnesses going around their child’s school.

“We can do better if we share information so we that know what’s going around,” said Dr. Bill Satterwhite.

So far, about 100 Charlotte schools are included.

An elementary teacher we spoke with said putting on hand sanitizer is a proven way to protect herself.

Doctors always urge everyone to wash hands with soap and warm water and get a flu vaccine.
