It is just too uncedible and incredible that such diseased human WMD's are being dispersed all over the USA without diagnosing or treating these diseases.
I have been seeing reports about the infected victims for years.
This administration has clearly lost control completely.
In the article it is stated that the new strains of TB are more difficult and cost hundreds of thousands and months to treat.
Isn't it ironic that the original native Americans were invaded back in the 1600's and contaminated with diseases from the invaders. And now We are suffering the same fate !
