TYLER (KYTX) - The number of Whooping Cough cases may be going up again.
There's a new, more powerful strain of the virus out there.
This new strain is harder to fight off.
We do know there are nearly a dozen confirmed cases of a new strain that doesn't have a particular bacterium, and that means it's resistant to the current vaccines.
Something some parents find alarming.
Car men Castro spends most Thursday's at the park with her daughter Lay la.
Her daughter's up to date on vaccines, but Carmen hasn't gotten her TDaP booster, which helps her stay protected against the Whooping Cough.
"I've seen about it, but I don't really know much. Just what I've seen on TV," says Castro.
She just found out about the new strain of Whooping Cough that could be worse than the outbreak we saw last year.
We saw case after case pop up in schools in East Texas and across the country.
"I think we'll probably see at least comparable numbers," says Russell Hopkins with NETHealth.
He says the 11 confirmed cases are in New England, but this isn't something researchers haven't seen.
"It's not a novel strain, it has existed in Europe before. We know about it. Just never seen it in the us before," says Hopkins.
The Centers for Disease Control says it needs more information before drawing any conclusions about this particular strand of the virus.
Hopkins says seeing all of these viruses, from the flu to pertussis, increase in numbers could just be part of the natural cycle.
"We go through series when viruses and bacterium alter their DNA and our vaccinations become, or antibiotics, become inefficient and we change them," says Hopkins.
But the idea of a more easily spread virus has Castro thinking about getting vaccinated anyway.
"I wouldn't want anything to happen to her," says Castro.
So this new bug could be what's caused more people to get sick in the past, or it could be something that could lead to more cases in the future.
Hopkins says get vaccinated, since the implementation of the shot, we've seen a 92% decrease in people catching the virus.
There's more research to be done, and that could lead to a new vaccine in the future.
The new bug was first reported in Japan, France and Finland.
A more in-depth study of this new strain is in the New England Journal of Medicine.
