An infectious disease specialist in the Bronx is helping to clear up questions surrounding the Legionnaires' disease outbreak. 

Dr. Edward Telzak, an infectious disease specialist from St. Barnabas Hospital, says that the borough's Legionnaires' outbreak is something to be concerned about, but that it's not rare. He says that while it usually occurs sporadically, it happens often enough that patients with pneumonia routinely receive antibiotics for Legionnaires' too. 

Telzak also offers reassurance about the two deaths associated with the outbreak. He says Legionnaires' typically only becomes fatal in people who have an underlying medical condition that creates other complications.

He adds that there is no evidence that Legionnaires' disease is spread person to person, and people should not be worried about drinking the water supply.
