the next level up would be diseases most americans have never heard of like benghi fever which has beenated or well controlled in the united states for, you know, decades. these suddenly are re-emerging. the problem, judge, is that lots of doctors, including myself, aren't going to be suspicious when they see a patient come in that it is denghi fever or some, you know, kra i zi tropical disease we don't usually see here. on the most serious front, you have two things. one is if you have measles as an example. or if you have unvaccinated children with chickenpox. these can spread very rapidly. you could have an epidemic disease and it does put people at risk. who is most at risk? it's goen to be the elderly, the very young, someone's immune compromised. say they're undergoing chemotherapy. they have congestive heart failure. and the worst, the nightmare we talked about this amp is going to be tuberculosis that's drug resistant. there isn't enough follow-up to make sure they're taking this multidrug regime to make sure they're curing tuberculosis. they might miss a drug or a few weeks. wi
