The original cases were in low income people who had been born outside the US but whose children were born in the US according to the paper.
Baffles me that someone would write something so definitively yet not expand on it in any way at all.
Not saying you're wrong (I have no idea), but what a low-effort comment. I'm curious, you seem (or claim, at least) to know something, can you help me satisfy my curiosity?
> The outbreak involved 13 people across four households in Kansas City and spanned 1 year. While a majority of the seven adults identified were born outside the U.S. in a country that had experienced a multidrug-resistant TB outbreak with the same genotype in 2007-2009, most of the six children were U.S.-born, noted Elizabeth Groenweghe, MPH, of the Unified Government Public Health Department in Kansas City, and colleagues in the Morbidity and Mortality Weekly Report.
So it's either been a latent infection in someone in the first household or they traveled to their home country and brought it back, or something.. it's likely the local health department knows the exact lineage and route it took but they avoid publishing the full details for obvious reasons in this climate.
But if that is what happened, then why not publish those details? If that isn’t what happened, then why not publish those details? Facts are always preferred to conjuncture.
