Some air carriers, including Spring Airlines and Juneyao Airlines, will gradually resume services in Shanghai from Monday, given a decline in the number of daily positive infections in the city.

Juneyao Airlines said it will restart its route from Shanghai to Longyan, East China's Fujian Province, on Monday, the first regular route for the carrier starting from Shanghai. The company said the rest of flights from the city will gradually resume depending on the situation.

The airline carried out several charter flights and temporary passenger flights departing from Shanghai since the beginning of May to meet the demand of work resumption.

Spring Airlines will resume flights between Shanghai and Kunming, in Southwest China's Yunnan Province, on Wednesday, with one flight scheduled daily.

According to the requirements of Shanghai, those who need to take a flight to leave the city must hold a negative nucleic acid test result within 48 hours and a negative antigen test result within 24 hours. Passengers entering Shanghai by plane are also required to present a negative nucleic acid test result within 48 hours.

Shanghai plans to restart business and services activities in phases from Monday, with shopping centers, supermarkets, pharmacies, wet markets, catering and hairdressing services to resume offline operation in an orderly manner, city officials said on Sunday.

Shanghai has further pushed forward the resumption of production, with nearly half of the 9,000 industrial enterprises above designated size having already resumed work.

The city reported 166 locally transmitted cases of COVID-19 and 1,203 local asymptomatic infections on Saturday, the Shanghai Health Commission said on Sunday morning.

Shanghai has closed half of the city-level makeshift hospitals and 95 percent of the 288 makeshift points in schools are no longer in use. The officials said that with cases declining gradually, patients treated at makeshift hospitals in Shanghai have dropped to about 50,000, one fifth of the peak number when the epidemic was at its worst.
