Transcript for Whooping Cough on the Rise?
As we head into flu season it's important to remember that this is also a time when other respiratory infections such as. Whopping -- that's right -- cop become more prevalent in fact in recent months we are seeing a rise in cases of -- -- across the country. So what does this mean for pregnant women and newborns and what can -- -- to reduce the risk. Joining us with more on this is ABC medical contributor doctor -- -- Customer it's great to see -- I do need a lot of people will be very surprised to hear that whopping -- is a danger again. Right it's making itself known again it comes every three or five years it's endemic -- it's all around us. Most -- we don't hear about it because most people are vaccinated. Young children are vaccinated but this last year there were 27000. Cases. And deaths. Deaths in little tiny tiny newborn babies so it is not a disability -- had no threat because fewer people are getting back -- but maybe one and one of the things is that. People are trying to prolong vaccinations as a whole issue would vaccinations and autism which was never proven. So. Kids are not getting vaccinated number one or they're delaying the vaccinations and they're getting it in the time. But we're learning just how right enters this -- explain to us first exactly when we'll -- cup is a bacterial infection. It's known as the -- because you have these coughing fits and it fits -- to like vomiting. To weight loss to breaking ribs that's also -- arguably and then. When you try to get air hit you get that there won't sound because there's -- inside. The Chinese called the hundred day. Flu because the coffin. Goes on for a hundred days and this is this can be fatal if a newborn so contracts in adults it's unusual to be fatal but -- it can knock you out and you -- these states happen in the middle of the night elect in in. Newborn newborn. And anyone talk about it's very very bad about is this about it right -- real focus of the healthcare community right now right as most pregnant women. Probably have had a -- -- they they were vaccine when they -- kids right. Under questionable whether they had that -- street -- to get -- -- in adolescence and and it wears off anyhow so now the idea is if we can this is brand new right if -- -- vaccinated women. Even during pregnancy that's the new part second or third trimester. The immunity will go to the baby the baby will be prevented. We tried something called cocooning before which was to immunize the mother right after delivering in the hospital. And if everybody around everybody the grandparents that's new one because they weren't recommending this for people over 65. The CDC change that now over 65 grandparents. Housekeepers nannies siblings. Everyone -- share and basically surrounding this baby in a cocoon of people that can't. Bring in and transmit the disease and more effective has that -- it's hard to get everybody wrecks that could mean hasn't been great because the issue is. Not everybody goes forward and -- we were talking that's a lot of vaccination and if you have one missing link that's it for another current idea say listen let's focus on the mother room let's immunize the mother during pregnancy get the passive immunity to the baby and then the baby's. Basically -- Because there is no vaccination for a newborn found that newborn -- -- you start to injections a little bit -- right right so someone's -- pregnant mother is injected with this -- right the idea is that the baby will receive some benefit that's right now says that -- -- holding true that's true mr. -- -- so and that's news this CDC just in June allowed pregnant women. To be vaccinated. That's great out there are certain outbreaks in certain pockets of the country right now that I have one going on right now in Suffolk County Long Island here in New York. Just started up California had a huge many potholes in California in 2010 and that was linked to perhaps they'll a group of teenagers that hadn't had the -- -- -- and. You know there's this whole movement -- and -- parents. Not unionizing spacing out the immunizations I remember one patient Tommy don't ever let your patient not get. The pertussis vaccine because her baby almost died I mean a lot of kids end up being hospitalized in developed pneumonia as what is the what do you see what is the -- even as antibiotics. Something like as it -- -- but -- it takes a while to work and the big -- is also diagnosing it because doctors are so used to seeing this and by the time you make that it starts off really simple just a runny -- a little cold -- goes up about a week it -- And then all of a sudden these -- -- and -- do you sell the that in no way they just keep on getting worse and worse and worse. They be loses weighed -- -- to turn blue. If it had seizures I mean the list goes on so it's easy to miss the beginning because -- beginning is that right all right -- -- -- -- the tests come back and everything else to write right thank you so much I don't know -- that's important information.
