WASHINGTON (AP) — Health and Human Services Secretary Sylvia Burwell says the federal government could have performed "much better oversight" of the Dallas hospital where two health care workers caught Ebola after treating the first U.S. patient with the disease.

Burwell says the government is taking more steps to help prevent the spread of infection at the hospital, including more intensive training for workers and a 24-hour site manager to oversee how equipment is being put on and taken off.

Burwell's remarks Wednesday on NBC's "Today" echo comments made Tuesday by Dr. Tom Frieden, director of the Centers for Disease Control and Prevention.

The Texas health department said Wednesday that a second health care worker at the Dallas hospital has tested positive for the disease.
