Michigan schools are scrambling to build plans for what to do if a student or community member is diagnosed with the potentially deadly new coronavirus.

School districts around the state are meeting with county health departments and preparing protocols that address everything from potential school closures to continuing school through online services if the outbreak were to reach Michigan.

There have been no confirmed cases of the new coronavirus in Michigan, though state health officials said recently that hundreds of people were being monitored.

One district that already has taken action is Novi Community School District in Oakland County, which has a large enrollment of students with family connections to China, Japan and South Korea, three countries with large coronavirus outbreaks.

In late January, Novi instituted a policy that students returning from trips anywhere overseas must stay out of school for two weeks, said Novi Superintendent Steve Matthews. So far, one student who returned to Michigan from a trip to China was kept out of school for two weeks, but has since returned to class, Matthews said.

Coronavirus cases now top 80,000 worldwide, with 2,666 confirmed deaths in China, and 34 in other countries, according to a World Health Organization update Thursday. The virus, which appears to have originated in China, has spread to 33 countries, including the United States.In China, schools nationwide have been closed since late January in an effort to stop the spread of the virus, which is passed like the common cold and flu. Japan announced Thursday that all that nation’s schools would be closed through late March to try to halt the spread of the virus.
