Abstract
Zhuhai Special Economic Zone, although distant from Wuhan City and Hubei Province, the source of novel coronavirus pneumonia, is facing a challenge. Most of Zhuhai's 1.89 million citizens are migrants who live and work in Zhuhai but return to their hometowns for the Spring Festival. On 2nd February 2020, Zhuhai citizens returned to Zhuhai for work, including many from Hubei Province. The first three cases of novel coronavirus pneumonia in Zhuhai were diagnosed on 20th January 2020. This number increased substantially after the Spring Festival; by 7th February 2020, 76 patients had been diagnosed and many more asymptomatic close contacts had been isolated for medical surveillance. The first three cases in Zhuhai had travelled from Wuhan, and over 78% of Zhuhai's 2019-nCoV patients are imported cases. The Government of Zhuahi has now cancelled all religious activities to avoid population gatherings. Zhuhai is a tourist destination, and all tourist attractions have been closed during the emergency. Public transport was reduced to <5% on 7th February 2020, encouraging residents to walk, ride bicycles or drive private cars. Zhuhai citizens are required by law to wear masks in public; residents can register their names online for masks from the Government of Zhuhai. Macau Special Administrative Region is close to Zhuhai, and all passengers travelling to Macau from Zhuhai are required to complete health declaration forms and undergo a body temperature test. University classes are now held online only, so students remain at home. Entry of outsiders is prohibited in all residential districts, and all residents undergo temperature checks before entering or leaving their residential districts. Citizens returning to Zhuhai from Hubei Province are required to isolate themselves for 14 days (Figure 1). In hospitals, information has been collected from medical staff with relatives in Hubei Province, and those who have had contact with Hubei residents since 11th January 2020 are required to isolate themselves at home. In clinics, patients with body temperatures >37.3°C are sent to fever clinics for examination, and clinic patients are forbidden from entering inpatient departments without instruction. Before being accepted for radiological imaging, clinic patients are required to complete a 2019-nCoV screening form. Each hospital department has reserved at least two wards for emergency isolation. Medical staff's mobile phones, spectacles, pens and stethoscopes are disinfected, and disinfection of lift buttons, public toilets and waiting-room benches has been increased. Training of cleaning staff has been strengthened, and the quality of protective clothing for cleaning staff has improved. For doctors, morning handover meetings have been reduced or are completed online. People are not permitted to eat meals in the hospital canteen; meals have to be eaten alone. To prevent waste of infection prevention equipment, users are required to register their names before using devices, and medical staff have to register real names before using equipment. Every morning and afternoon, medical staff report their body temperature to the infection control department. In addition, Communicable Disease Control (CDC) staff send respiratory samples from themselves for virus detection after completing each epidemiological investigation. In surgical departments, surgical procedures on suspected patients are assigned to particular surgical groups. Medical shelters have been established by Zhuhai People's Hospital for identified close contacts. Shelters are responsible for classifying contact types and stratifying the level of risk. If clinical suspicion of infection is found in screened cases, they are sent to hospital immediately. Shelters are equipped with medication, physicians and a team of chefs. Channels have also been established for immediate transportation of close contacts and supply of medication. A psychological service has been established to address the anxieties of isolated persons. Zhuhai CDC has established 10 emergency response teams for epidemiological investigation, case report, specimen collection, epidemic site disinfection, close contact management, emergency monitoring, health education, risk assessment, technical guidance, etc. Inspectors detecting the virus wear protective clothing, including N95 masks and goggles. Medical staff have been sent to bus stations, quays, rail stations and airports to undertake screening. Fever clinics in Zhuhai operate ‘around the clock’. Zhuhai Health Bureau staff have inspected all medical institutes and drinking water production plants in Zhuhai. Zhuhai, as an important part of Guangdong–Hong Kong–Macau Great Bay, faces major challenges due to its large immigrant population. However, much has been learned from this emergency, and we hope that some of our experiences will assist others in planning responses in their regions. The authors wish to thank Zhuhai CDC for providing the necessary support for this study. None declared.
