A total of 173 students and staff at 41 K-12 school districts have been infected by coronavirus in new school-related outbreaks, according to data released Monday, April 19, by the Michigan Department of Health and Human Services.

The data was collected on Thursday, April 15, and includes preschools and daycares in those buildings

Last week, the state reported 201 infections in new outbreaks at 48 K-12 school districts and three colleges.

The biggest new outbreak involves 21 students and staff at Imlay City Middle School near Lapeer.

K-12 school outbreaks were identified in 28 counties. Below are those outbreaks listed by county.

A cumulative total of 8,559 individuals have been sickened in ongoing outbreaks, the April 19 report says. Ongoing outbreaks include clusters identified earlier but that had at least one additional case in the past 28 days.

Last week, there was a cumulative total of 9,886 cases in ongoing outbreaks.

Most of those ongoing outbreaks involve college communities, and most of those outbreaks occurred outside classroom settings. A total of 7,895 infections linked to ongoing outbreaks have occurred in and around 18 college communities. That compares to 7,827 cases on 23 campuses reported last week.

Among K-12 schools, there were 2,166 staff and students infected in ongoing outbreaks at 269 schools serving pre-K through high school.

The latest list includes buildings with at least one case in the past 28 days.

The largest ongoing outbreaks in K-12 schools: 56 at Ruth Fox Middle School in Lapeer; 54 at Lapeer High School; 50 at Imlay City High School; North Branch Elementary, 48, and East Grand Rapids High School, 45.

Outbreak data for K-12 schools includes only cases in which the student or staff was infected at school or at a school-related function. Those who caught the virus outside of school are not included.

A COVID-19 outbreak is defined as two or more cases with a link by place and time indicating a shared exposure outside of a household.

Below is an online database that allows readers to search outbreak data by school name or by city or county. The number of those infected is a cumulative total since the original outbreak. (Note: Washtenaw County only reports cumulative totals for the past 28 days.)
