Limited resources

Ma Xiaowei, minister of the National Health Commission, said in a signed article on April 18 that China's medical resources are insufficient in general and could collapse if the virus runs rampant.

Data from the commission show there were 2.9 doctors and 3.34 nurses per 1,000 people in 2020, lagging behind a number of developed countries, including Australia, which had 3.8 doctors and 12 nurses per 1,000 people.

Du Bin, vice-president of Peking Union Medical College Hospital and a critical care specialist, said in a study published in June that China only had 3.6 intensive care unit beds per 100,000 people, compared with 34.7 such beds in the United States and 29.2 in Germany.

"There was a large gap between critical care delivery and demand," he said in the co-authored article, adding that the lack of professional critical care health workers further strained capacity.

Shanghai, which is home to renowned hospitals and top medical professionals, has had to seek help from outside amid the current outbreak.

Jiao Yahui, head of the National Health Commission's medical administration bureau, said that as of April 4, more than 38,000 medical workers from 15 provincial-level regions had been sent to the city to help fight the virus.

In a sign of the increasing pressure on designated hospitals, the city announced last week that 6,700 beds in makeshift facilities initially designed to receive asymptomatic or mild cases would be upgraded to accommodate patients with moderate symptoms of COVID-19.

Liang Wanxian, an expert with the commission's virus response task force, said on Friday that relaxing COVID-19 control at present would trigger a "vicious circle". The surging number of severe cases could collapse the medical system and lead to cross-infection among health workers, hampering the provision of other medical services.

Spillover effect

Experts said that as Shanghai is a major transportation hub, COVID-19 cases in the city may spill over to other parts of the country. As a result, it is crucial to uphold dynamic clearance and for the outbreak to be brought under control as soon as possible to reduce its impact.

Shanghai has one of China's most developed and interconnected public transportation systems. As of the end of 2020, the city operated 1,585 public transportation routes with a total length of 9,116 kilometers, according to the Information Office of Shanghai Municipality.

Moreover, Shanghai has 14 municipal highways and seven national expressways connecting to other big cities, including Beijing, Xi'an, capital of Shaanxi province, and Kunming, the Yunnan provincial capital. Shanghai also has 67 roads leading to the neighboring provinces of Jiangsu and Zhejiang.

Shanghai Pudong International Airport is one of the busiest in China. In 2019, it handled more than 76 million travelers, 511,840 flights and over 3.6 million metric tons of cargo.

Xu, from Shanghai Jiao Tong University, said that if the city cannot achieve dynamic clearance of cases, the virus may spill over through human transmission or through goods to other parts of the Yangtze River Delta region and even the entire country.

"This may have a growing negative impact on China's social and economic development. In the short run, life and the economy in Shanghai will be affected by the quarantine measures, but taking the nation as a whole, containing the spread of the virus within a specific region will ensure the rest of the country maintains normal operation," he said.

"Therefore, Shanghai must uphold the dynamic zero-COVID policy. This is a sound strategy that will ensure the stability and growth of the region and the nation," he added.

Wu Huanyu, deputy director of the Shanghai Municipal Center for Disease Control and Prevention, said in an article posted by the city's information office there would be unimaginable consequences if Shanghai did not abide by the dynamic clearance policy.

If the number of infections continued to rise rapidly, the virus could mutate into something more serious, which is a risk that the city could not take, Wu added.

Lessons learned

Experts said expanding the use of rapid antigen tests, enhancing logistical support for people in quarantine, and monitoring quarantined patients with special medical needs are key lessons learned from the outbreak in Shanghai that will ensure the dynamic clearance strategy is carried out effectively.

Zhao Jing, an official at the National Health Commission, said in an interview with Health News, a media outlet operated by the commission, that to cut off the virus' transmission chain, it is crucial to find all infected cases as soon as possible and place them in quarantine.

However, nucleic acid tests, while highly accurate in identifying new cases, can take a considerable amount of time and resources if done routinely and on a large scale. On the other hand, antigen tests, although less accurate, are convenient and produce quick results that are suitable for routine self-checks, Zhao said.

"These two methods are complementary and can help track cases more efficiently," he said. For instance, if a self-test returns positive, medical workers will arrive at that person's door to administer a nucleic acid test, which is more convenient than going door to door or organizing mass screening, he added.

Across the country, antigen tests are not only being used for those in quarantine, they are also acting as a safety precaution for people returning to work.

A shopping mall supervisor in the Hunan district of Shenyang, Liaoning province, said each of its workers were given five testing kits before resuming work. "This made everyone feel safe," he told the district's publicity department.

As of April 13, the National Medical Products Administration had approved 26 antigen testing kits. Last month, the authorities in Guangdong province ordered a stockpile of antigen tests equivalent to 10 percent of the local population to be acquired before April 15. Last year, 127 million people were resident in Guangdong.

In addition to tracking cases, logistical support is crucial to winning the battle against COVID-19.On Saturday, Yang Yuanfei, vice-governor of Changning district in Shanghai, said at a news briefing that more than 1,070 couriers had been hired to transport goods locally.

The district has also set up 18 courier stations to handle everyday needs and has established express channels so that couriers can take nucleic acid tests and get the results quickly.

Logistics companies are also conducting daily random antigen and nucleic acid tests on their employees. "These measures ensure that our couriers can do their jobs safely and that residents receive their deliveries safely," Yang said.

Wu Qianyu, an official at the Shanghai Municipal Health Commission, said on Friday that the city places great importance on helping those with special medical needs during the outbreak, particularly pregnant women and people with underlying health conditions.

Hospitals and other medical facilities have set up quarantine zones to serve these patients, providing prompt medical aid while they wait for COVID-19 test results, she said.

A number of highly capable medical facilities in Shanghai have been selected to focus on treating severe and critical cases in an effort to reduce the mortality rate, Wu added.
