City has no asymptomatic cases

SHANGHAI has no asymptomatic cases of COVID-19 under medical observation at present, the local health commission said yesterday.

The city started reporting updates on asymptomatic cases daily based upon requirements from the National Health Commission, Zheng Jin, a spokeswoman for the Shanghai Health Commission, told reporters.

There have been 11 passengers arriving in Shanghai from overseas whose nucleic acid test results were positive, yet who showed no obvious symptoms at that time, said Zheng. They were sent to designated fever clinics for quarantine and medical observation.

One was declared not infected, while the rest later developed clinical symptoms and were confirmed as infected based on epidemiology history, laboratory tests and imaging examination.

“Strict prevention and control measures have been imposed on such cases, including transferring them to designated clinics for medical observation and to designated medical treatment institutions immediately for quarantine and treatment if they are confirmed as infected,” Zhang said.

“Asymptomatic cases will be discharged from hospital only when their nucleic acid test results are negative twice,” she said.

“They are required to undergo a 14-day quarantine and medical observation after being discharged from hospital.

“They will be visited by medical workers on the second and fourth week after being discharged from hospital for subsequent medical checks.”

“Screening of close contacts of asymptomatic cases will be enhanced and monitoring of people from key countries and venues will be strengthened,” she added.
