Some good news has been reported in regards to the Andrew Speaker saga. It turns out his TB is not XDR-TB, or extremely drug resistant, but simply multiple-drug-resistant MDR-TB. This means that he may be treatable and anyone who may have been infected would also be treatable. This reduces the risk of a catastrophic outcome.
What this doesn't change is that Mr. Speaker willingly, and with full knowledge of his actions, risked the health and lives of hundreds of people to get back to the US when ordered by the CDC to quarantine himself in Italy. Mr. Speaker is still guilty of gross negligence, but at least the potential victims of his selfish behaviour have less to worry about now.
