In addition, the age group with the highest infection rate in Ingham County is 20-29 at 28%. Ages 30-39 trails behind, at 19%.

"Statewide, this is where we're seeing the highest number of cases," Vail said. "When we look at those cases by rate, rather than just percent, we see the 30-39 age group is the highest age group, followed by 20-29 and 40-49."

This is also impacted by vaccination rates.

"When we get into that 30-39 and 20-29 age group, we see some of our lower vaccination rates, as well," Vail said.

In the past week, 3,743 cases of COVID-19 were referred to the department. In addition, there are 47,951 cumulative cases, with 8,758 of those active.

"We have a significant surge in cases," Vail said. "The highest percent positivity we've seen."

There are a total of 587 deaths, Vail said. Three of those deaths happened since Jan. 4. The cumulative case fatality rate is 1.3%.

According to data from Sparrow Hospital and McLaren Greater Lansing, 174 COVID-19 hospitalizations are on the hospital floor, 40 in ICU and 28 ventilated.

"Omicron hit and we are on our way up with hospitalizations, ICUs ventilation," Vail said. "You can see this overall general trend in emergency department visits ...We are getting some really high numbers there."

In January alone, 45% of cases in Ingham County are Caucasian, 16% African American, 4% Asian and 17% identified as other race. For every 100,000 African Americans, 1,989.7 are infected. For every 100,000 Caucasians, this rate is 878.3.

"We have a market difference in our Caucasian population versus our African American population," Vail said. "That's over 100% difference."

In 2021, December had the highest number of deaths in a month. It is the second-highest month of deaths overall since the beginning of the pandemic.

In January 2021, 18.4% of cases are active and 80.4% are recovered.

Of people ages 16 and up, 76% are vaccinated. Vail said that 71.9% of all eligible Ingham County residents have received at least their first dose.

"Vaccination rates are creeping up quite slowly in almost every age group, except for the 18-24 age group ... where we're just not making a lot of progress," Vail said. "That explains the higher number of cases in the 20-29 and 30-39 age groups."

In addition, nearly one in every 10 Michiganders were reported with COVID-19 in 2021.

The department will be hosting vaccination events with Michigan State University in the next few weeks. There will be more details about where and when at a later date.
