Two separate lawsuits have been filed over the deadly Legionnaires' disease outbreak in Harlem. Both lawsuits claim construction companies failed to protect workers from unsafe conditions that led to the spread of the disease.

About one in 10 people who get sick from Legionnaires' disease die from the disease due to complications from illness, CDC said.

A fifth person has died as a result of the Legionnaires’ disease outbreak in Harlem, which has sickened more than 100, health officials said.
