It is not passed person to person but is contracted by inhaling droplets of the contaminated water. "The Health Department will evaluate the building's plumbing to look for evidence of Legionella bacteria in the building's water system", officials said.
At least a dozen people were sickened from the disease; one elderly person died.
While state officials continue their investigation of the 14 cases of Legionnaires' disease in the Ashworth Avenue area of Hampton Beach, Nashua health officials said two cases occurred there in August.
The Centers for Disease Control is assisting state health officials in confirming the source of the outbreak.
Test results from other locations in the affected area are still pending.

Officials believe the current overall health risk to the community is low. Groups at highest risk for Legionnaires' disease include people who are middle-aged or older, especially cigarette smokers, people with chronic lung disease or weakened immune systems and people who take medicines that weaken their immune systems (immunosuppressive drugs). "Through regular communication and transparency, we will ensure members of the public have the most up to date information so that they can make the best decisions for themselves and their families".
Legionnaires' disease can not be spread from person to person.
The Department of Health found six of the 13 water tanks at the Saint Nicholas Houses tested positive for elevated levels of Legionella bacteria.
The disease can not be spread through person-to-person contact, nor by drinking contaminated water. Most people get better with early treatment, although they may need to be hospitalized. A spokesperson said there have been fewer than 10 cases reported.
In Nashua, one of the disease victims was afflicted out of state, officials said.
