Listen: United States, Dr Anthony Foudy, National Institute Of Allergy discussed on All Things Considered
"Things considered. Audie cornish. And I melted chain disease that we thought was Radic aided in the US almost twenty years ago is now spreading rapidly. We learned this week that the measles virus is on the rise. And if the trend continues the US is on track to have the worst outbreak on record since the disease was thought to have been eliminated in the US in two thousand measles can be fatal. It can con- Stephanus blindness and even brain damage, Dr Anthony Foudy is the director of the National Institute of allergy and infectious disease. He joins me now to talk about what's behind this spread. Welcome to be with you. So why are the numbers going up such a startling rate? Right now, you know, it's really the unfortunate situation of people not vaccinating their children and the level of coverage in a given community when it falls below a certain critical level, you get the kinds of outbreak. That was seeing but typically in places like new city in the Williamsburg section of Brooklyn where the percentage of a given community. This is a relatively close community civic Jewish community that area that are not vaccinating their children at a rate that would provide that broad umbrella of protection that we call her immunity. Someone enters the community of visit from outside in this case. It was someone who went to Israel and came back from Israel who is infected then you have the kinds of outbreaks that we're seeing I wanna make sure I understand this phrase that you just use the phrase herd, immunity, is it basically the minimum number of people in the community that should be vaccinated in order to prevent the spread of disease right virus? Does not get any momentum in a community. When you have a high percentage of the people who are vaccinated with measles that critic level of herd immunity somewhere around ninety three to ninety five percent since quite extensive really means to be very high twenty drop down to the eighties or even the seventies or even lower where it is now in that community. That's exactly the explanation of why we're seeing the outbreaks that we're seeing you could just put the most recent outbreaking context for us. I know that a lot of outbreaks have happened in small. Communities of people that have a high rate of people who are not vaccinated those outbreaks threaten people who are Sonate. No, if you have accented you as an individual going to be safe if you are in a community in which you're not back Sonate, but there's a low percentage of people who are accented you're not going to be protected, which is exactly what's going on. But if you're fully vaccinated, if you have the two components, which is usually given from twelve to fifteen months of age, and then a booster at four six years. You're protected and durably protected. Do you feel like we are losing the battle against the spread of measles? Well, if things continue the way they are now, I do think that that is an unfortunate consequence of what's going on right now because if people continue to under vaccinate in communities, we're gonna see more outbreaks, and I think the important point is that people sometimes incorrectly and inappropriately think that to get infected with measles. Is a trivial disease. It is not it can be very dangerous because if you look at the history of measles, Pryatta, vaccinations that were available throughout the world. There were a couple of million deaths per year with measles the United States in the mid nineteen sixties they were about two to three million cases of measles and about five hundred deaths per year. So we should not consider measles as an insignificant disease. And that's the reason why was so frustrated when we see the outbreaks that are recurring throughout the country, particularly now, currently the lodge outbreak in New York City, Anthony is the head of the National Institute of allergy and infectious disease. Thank you very much for joining us today to be with you in recent weeks. President Trump has repeatedly claimed the US can't handle the number of migrants coming through the southern border. The system is full can't take anymore. Some employers in the mid west say, they're facing a far different. React. -ality? Iwa public radio's grant girl reports businesses. There are relying on immigrants to help them rebuild a shrinking labor force the comment from the president came during his visit to the US Mexico border in California where more immigrants have been seeking asylum. Well, the immigration system is clearly under strain experts say there's plenty of room for more workers for some businesses. Finding enough workers is."
