Two more deaths have been linked to the Legionnaires' Disease outbreak in Genesee County.
Monday's update brings the total number of deaths to 12 and a total of 91 Legionnaires' cases for the 2014 and 2015 outbreaks.
Legionella is a type of bacteria that grows best in warm water such as potable water systems (hospitals, large buildings), hot tubs, cooling towers, and decorative fountains. When people are exposed to the bacteria, it can cause legionellosis, a respiratory disease that can infect the lungs and cause pneumonia. The bacteria can also cause a less serious infection called Pontiac fever. Legionella is not transmitted person to person.
The increase in Legionnaires' Disease happened around the same time Flint switched its water source.
But health officials have not confirmed a link between the two.
