GRAND RAPIDS, Mich — Across the country, cases of COVID-19, influenza and RSV are increasing with cooler weather and as people gather for holidays. 

In Michigan, the deputy state epidemiologist says the Michigan Department of Health and Human Services is seeing increases week after week for the past few months. 

"CDC is seeing nationally, again, nationally, seeing some of the highest numbers of COVID wastewater concentrations that they've seen, at least over the last 12 months," said Joe Coyle, deputy state epidemiologist. 

In Michigan, and the Midwest, Coyle said there may be higher than average levels detected in wastewater than certain areas of the country. 

"I don't think we are over our peak yet, necessarily, for RSV, definitely not over our peak for COVID, and influenza is just starting," said Coyle.
