FLINT, MI -- Flint residents once concerned about lead levels in their drinking water now face a new fear with increased cases of Legionnaires' Disease in Genesee County.

Gov. Rick Snyder announced Wednesday, Jan. 13, a spike in cases of Legionella bacteria has been discovered in Genesee County following the switch to Flint River water as the city's main drinking source.

The state said 87 cases, 10 fatal, occurred in the Flint area from June 2014 to November 2015, but said there's no evidence of a clear link between the outbreak and the water system change that's caused an uproar over elevated lead levels found in Flint children.

However, the Virginia Tech university professor who spent months studying Flint's water problems says the failure to treat Flint River water to make it less corrosive could have set off an outbreak of Legionnaires' disease here.

Rachael Mingo was at the Flint Fire Department picking up free water on Wednesday. Mingo said she has been so concerned over the water, she hasn't used it at her house in more than a year.

"I have been totally paranoid about it. It's disgusting and it's not fair," Mingo said. "I think it's inhumane and I hate to point a finger at anybody, but anybody who can do this kind of stuff to innocent people? People who aren't even educated to know about these kinds of things."

Mingo said she and er 1-year-old and 3-year-old children have been tested for lead, but she hasn't had her water tested yet. With the new concerns over the Legionnaires' Disease, Mingo said she also plans to have her water tested for the bacteria. She said she no longer bathes her children in the water.

"We just haven't been using it at all except to flush the toilet and was our hands," Mingo said. "I give my kids a bath once a week in Detroit when I'm going to church. To not be able to use it, they don't even get bath time. Kids love bath time and to not even be able to give that to them out of fear."

Flint resident and water activist Melissa Mays said she is "heart-broken" that information on the outbreak wasn't shared prior to Wednesday.

"This is horrifying and shocking because it proves we are not even safe to shower." Mays said.

Lavonda Baker said she has lived in Flint her whole life and is scared of what the water is doing to her body.

"I'm 57-years-old and ever since I have been drinking it I've been getting sick and getting spots all on my arms," Baker said. "I'm constantly buying water and buying water and buying water and it's bad you have to do it and we have to drink it."

April Ewing was loading free water into her car at the fire department on Wednesday night as well. Ewing feels scared about the news of a spike in Legionnaires' Disease cases in the county. She said she hasn't had her water tested since the Flint water crisis began.

"I want to, so bad," Ewing said. "I want to know."

The Michigan Department of Health and Human Services on Wednesday released its June 2015 initial report on the outbreak that investigated the first 45 cases reported between June 2014 and March 2015.
