With the local medical system in Nagoya under strain due to the fifth wave of COVID-19 infections in the city, more than 6,000 coronavirus patients have been forced to recuperate at home.

Tasked with monitoring the condition of such patients are local public health centers, which are swamped with work amid the surge in infections.
