my brother is in the marines and right now is in DC on a base. but ticks can carry a disease called limes disease, but they would've mentioned it! limes disease is cureable, it takes about two weeks to clear up completely. my cousin just had it! but if it gets into your blood stream its deadly, im going to guess that he didnt get bitten by a tick with limes disease, because they would've mentioned it, and if he did get bitten by it, it isnt deadly, its just like having a cold.
god bless.
