Crew members and civilians who were aboard an aircraft carrier in San Diego are being testing for tuberculosis after some crew members tested positive for TB.

In an initial round of tests, some crew members aboard the Ronald Reagan showed positive tests results, prompting officials to test all 4,800 crew and 2,000 civilians who were aboard. The civilians were family members and guests who had joined the crew for a voyage from Hawaii to San Diego, The Los Angeles Times reported.

Capt. Frank Chapman, a Navy doctor, said the Reagan's commanding officer, Capt. Terry Kraft, ordered the entire crew and all passengers screened for TB to "identify everyone who may have been infected and begin any necessary treatment."

The Ronald Reagan had recently returned to San Diego after a six-month deployment to the Persian Gulf.
