German schools, reopened a month ago, have seen no major coronavirus outbreaks

But there have been few transmissions within schools themselves, health experts say, and although the number of new daily cases in Germany has been rising, schools haven’t been identified as a driver of infections.

“It’s looking promising,” said Johannes Huebner, president of the German Society for Pediatric Infectious Diseases. “There have not been any major outbreaks yet. Single cases, but they seem to be manageable.”

While Germany’s full-throttle return to class may provide some assurance for those fretting about school returns in the United States and elsewhere, health experts note that it’s still just the early days — and they warn about extrapolating too much. They say the risk associated with reopenings has a lot to do with the levels of the virus circulating in a community.

“The important thing is you have to keep the number in the community low,” said Huebner, who is also head of the infectious-disease department at Munich’s Dr. von Hauner Children’s Hospital. “This is where the United States will have problems.”
