COVID-19 outbreak is hitting Shanghai "harder than authorities have publicly disclosed"

Via the Wall Street Journal (Journal is gated but there is the link if you can access it):

• Many patients have died in recent days at a large Shanghai elderly-care hospital that is battling a Covid-19 outbreak, according to people familiar with the situation, a sign that a new wave of infections is hitting China’s financial capital harder than authorities have publicly disclosed.
• Shanghai’s government hasn’t reported any Covid-related deaths or outbreaks in its hundreds of elderly-care centers since cases began climbing in the city in March.

This from overnight:

• Shanghai will lockdown areas with cases for 10 more days

Its not only Shanghai, outbreaks in China are across multiple cities and regions.
