SHANGHAI, China - Not only is there no cure for COVID-19, there's also still no cure for boredom. 

That noise is of people screaming and shouting out of frustration from the balconies of one of Shanghai's largest residential compounds after days of coronavirus lockdown in the biggest Chinese city with no clear end in sight.

Under China's "zero-COVID policy" a five-day lockdown was planned to combat a rise in cases. That began on March 28th. Some of the city's 26 million residents have been confined to their homes ever since, and are not allowed to go out and get what they need.

A video circulating on social media shows people yelling from their windows after being confined to their homes for seven days in Zhongyuan Liangwancheng, one of the biggest residential compounds in the city.

The man who filmed the video can be heard saying that within five minutes, the entire area was screaming. In a mix of Shanghainese and Mandarin he said,  "That entire building is screaming. This is Zhongyuan Liangwancheng. Everyone is screaming. Damn. Just now. Five minutes ago, not that many people were screaming. Now all of a sudden, everyone is screaming. Damn. (PAUSE) Damn. If it continues to be like this, I can tell you, something will go wrong. What's the root problem? Because all people here they don't know how long this situation will last. There needs to be some standard or a detailed statement. Nothing. Being in lockdown for seven days, staying at home, cannot go outside of your door, not even talking about a ban on going out of your compound. This can't work, something will go wrong."

Earlier in the month, residents of the Top of City compound in Jing'an district also had a similar spontaneous screaming session.

Another resident reportedly said of the massive audible response, "isolation with no clear end in sight is stressful."

In Shanghai, more than 200,000 cases but no deaths have been reported in the latest wave of coronavirus infections which prompted the shutdown starting March 28.

The government eased restrictions by announcing residents of areas with no cases for at least two weeks can leave their homes starting Tuesday. It said they could go to any other area that also had no new cases during that time but were urged to stay home when possible. Such “prevention areas” have about 4.8 million people, The Paper reported, citing city officials. It said all but 500,000 of those were in less densely crowded suburbs. An additional 1.8 million people in “control areas” with no new cases in the past week are allowed out but can't leave their neighborhoods, the report said. Another 15 million people in “quarantine areas” that have had infections in the past week still are barred from leaving their homes

After Shanghai announced a 3 -tiered lockdown, Jinshan District published the first batch of communities listed as precautionary and controlled areas. Residents in the precautionary area can enter and exit the community once per day with a pass to purchase necessities.

The closed area and controlled area are to remain isolated, and staff and volunteers are on duty 24 hours a day to strictly prevent residents from entering or leaving. Supplies are delivered to the entrance of these communities before being relayed to households by volunteers and community workers.

The Fumin Community in Zhangyan Town, Jinshan District is one of the precautionary areas. After the lockdown was lifted, the largest supermarket in the town opened for business at noon.

Flour, rice and instant noodles were sold out instantly. Meat, fruit and other non-staple food supplies were more abundant. The supermarket said it will extend operating hours and resupply.

Dongfeng New Village in Zhangyan Town is also a precautionary area. Its iron fences have been removed, and residents can enter the community with a latest negative nucleic acid test result and an entry pass, but only one person of one household can go out once a day.

Lane 173 on Xinhua Middle Road belongs to the controlled area. In order to prevent residents from entering the area by mistake, the junction of the two zones was separated with an iron fence, and the residential areas along the street were also cordoned off.

Meanwhile, the U.S. has ordered all non-emergency staff to leave our consulate in Shanghai, which is included in the lockdown.

The State Department also issued a series of advisories for other Americans in China's largest city, to help ensure they have the supplies they need, especially in the case of more unexpected restrictions.
