The island's health care system will be put to the test as reports of leptospirosis, a bacterial disease, are beginning to emerge. The governor has repeatedly said that he is concerned about a possible public health emergency in the wake of Hurricane Maria, which has led to the deaths of at least 44 people on the island.

In preparation, the U.S. Navy's floating hospital, the USNS Comfort, arrived in Puerto Rico last week. On Tuesday, the 894-foot-long ship departed San Juan for Aguadilla to conduct medical support operations, the Department of Defense said.

The Comfort is said to have one of the largest trauma centers anywhere in the U.S. and maintains up to 5,000 units of blood at any given time for its medical services.

Additionally, U.S. Northern Command deployed resources on Wednesday that include elements of the 633rd Expeditionary Medical Support hospital, which is scheduled to arrive in Aguadilla on Saturday.

Approximately 13,600 Department of defense personnel are responding to hurricane relief efforts across Puerto Rico and the U.S. Virgin Islands.
