I’m sitting in the Newark airport and having a sandwich at the Earl of Sandwich (it’s the only place I can sit down here, it seems). There was a sign as I came up the ramp for “PI” stating that “He’s a child isn’t a diagnosis”, implying that your child’s cold could be a sign of “PI”. As I’m sitting here eating this club sandwich, there’s another sign outside the restaurant also for “PI” or “Primary Immunodeficiency”.
Primary immunodeficiency is a condition that affects (at best estimate) about 1 in 100 000 births. There are at least 5000 people that see that sign every day. Of those 5000 people, a much lower number of them will have children and even lower still, the number of those individuals who have a child less than 1 year old. In 20 days (almost a month), that sign would be applicable to a single individual if they were all infants under the age of 1. How many days would it take to pick up one case of PI? Probably more than 6 months to a year. Important? Yes. Because PI or SCID (Severe combined immunodeficiency) can result in DEATH before the age of one year if untreated.
