Increase in COVID-19 Cases in South Lyon and Fenton Region

Oakland County Health Division, Livingston County Health Department and Genesee County Health Department report a steep increase in COVID-19 cases in the South Lyon and Fenton areas since mid-July among individuals 15–19 years-old.  Some of the cases reported attending large indoor and outdoor gatherings, including graduation parties and prom like events, during July.

“We need parents and young people in our community to recognize the risk they take to their own health and that of their family and friends when attending gatherings without taking precautions,” Leigh-Anne Stafford, Health Officer, Oakland County Health Division said. “We can work together across our communities to contain the spread and I urge parents to be aware of activities your kids attend.”

“When attending both indoor and outdoor gatherings, it is important to stay six feet from others and wear a mask,” Dianne McCormick, Health Officer, Livingston County health Department said. “Socializing responsibly could help quickly turn things around.”

“When individuals cooperate with Health Departments to complete contract tracing and case investigations, it goes a long way to stopping the spread of COVID-19,”John McKellar, Health Officer, Genesee County health Department said. “No one wants to be the one who spreads COVID-19 to someone who becomes very ill or dies.”

Preliminary information indicates a significant increase in cases among high school age students and those numbers could change as case investigation continues in the three counties. In Oakland County, COVID-19 cases among 15–19-year-olds in the South Lyon area increased from three cases during late-June to mid-July to 42 from mid-July to early August. Similar trends for this age group have been observed Countywide in Livingston and Genesee counties. For Livingston County, cases increased from three cases during late-June to mid-July to 19 from mid-July to early August and in Genesee County, cases increased from 19 during late-June to mid-July to 94 from mid-July to early August.

The three health departments are conducting case investigations to identify individuals who have potentially been exposed. Initial information has determined that 15 – 19-year-olds from Oakland Livingston and Genesee attended at least six large gatherings.
