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 pair of construction companies overlooked safety concerns, causing a “completely preventable” outbreak of Legionnaires’ disease in New York City that's killed at least five people and sickened dozens more, according to lawsuits filed on Wednesday.
