All three were unvaccinated and had underlying health conditions such as coronary heart disease, diabetes and high blood pressure, according to officials.
On Tuesday, Shanghai’s health commission reported another seven Covid deaths, aged between 60 and 101 and all had underlying ailments.
The city reported 3,084 symptomatic cases and 17,332 asymptomatic infections Tuesday, according to the statement.
The death toll appears strikingly low against the vast number of cases — since March 1, more than 390,000 people in Shanghai have been infected, and by the official count, no one had died of Covid until Sunday.
Shanghai’s low official death toll has raised questions among some experts outside mainland China, especially given the vaccination coverage among the elderly in Shanghai is not that much higher than that of Hong Kong.
Jin Dongyan, a virologist at the University of Hong Kong, said Shanghai’s low death toll is partly a result of how Covid deaths are counted in mainland China.
“The methods used by Hong Kong and the mainland to calculate deaths are completely different. Over 90% of the Covid deaths reported in Hong Kong will not be counted on the mainland,” he said.
In Hong Kong, a person is counted as having died of Covid if they were confirmed to have contracted the coronavirus less than 28 days before their death — even if they died of suicide or road accidents, Jin said.
“On the mainland, if the deceased had underlying ailments, most of them would be categorized as having died of other diseases instead of Covid,” Jin said.
This is only the second time mainland China has reported Covid deaths this year. Last month, the northeastern province of Jilin reported two deaths — the first in more than a year. Throughout 2021, mainland China reported only two Covid deaths, both in January.
Chinese officials and state media have attributed the country’s low death toll to the supposed success of its zero-Covid strategy, often contrasting it with the hundreds of thousands of deaths reported in Western countries.
But increasingly, the low official death toll is also raising questions among many Shanghai residents over whether it is justified to impose the kind of stringent measures that have upended the lives of millions of people.
The reported deaths come as the metropolis of 25 million people continues to endure a grueling lockdown, which has ground the vibrant, bustling business hub to a virtual halt.
Residents have been confined to their homes for three weeks and counting, with many complaining of food shortages, lack of medical access, poor conditions at makeshift quarantine camps and heavy-handed measures such as separating infected children from their parents.
On China’s heavily censored social media, users have resorted to creative ways to express growing discontent toward the prolonged lockdown, including posting under seemingly irrelevant hashtags that deliver veiled criticism or sarcasm. But those hashtags are often censored too after they draw widespread attention.
On Sunday, the latest censored hashtag on Weibo, China’s Twitter-like service, is the first line from China’s national anthem: “Stand up! Those people who refuse to be slaves!”
