Contagious Stomach Bug Spreading Across MI: CDC

MICHIGAN — Cases of a nasty stomach bug known as norovirus have spiked in recent weeks across Michigan and several other states, according to recent data published by the Centers for Disease Control and Prevention.

Norovirus is a contagious virus that causes vomiting and diarrhea. The virus is the "most common cause of foodborne-disease outbreaks," the Michigan Department of Community Health said.

The virus is often spread through direct contact with an infected person, eating food or drinking liquids contaminated with the virus or touching contaminated surfaces, the CDC said.

According to CalciNet data published through the CDC, Michigan has had one outbreak from Sept. 1, 2023-Jan. 31.

The Michigan Disease Surveillance System recorded 156 norovirus cases in the past four weeks.

When infected with norovirus, symptoms usually begin 12-48 hours after first exposure and last for one or three days, the Mayo Clinic said. In addition to vomiting and diarrhea, symptoms include nausea, stomach pain, fever and muscle pain.

There is no treatment for norovirus.

About 19 to 21 million norovirus illnesses are reported in the United States each year, according to the CDC. Most illnesses commonly occur between November and April. Norovirus causes about 109,000 hospitalizations each year and 900 deaths, most commonly among older adults, the CDC said.

To prevent the spread of norovirus, the CDC recommends washing your hands with soap and water, cleaning and disinfecting surfaces with bleach and thoroughly washing laundry. Officials also advise washing fruit and vegetables, thoroughly cooking seafood and not preparing food or caring for others when sick.
