China’s aviation regulator recommends cabin crew on charter flights to high-risk destinations should wear disposable diapers and avoid using the bathroom to reduce the risk of infection.

The advice comes in a 38-page list of guidelines for airlines to prevent the spread of coronavirus, Bloomberg reports. The sixth edition echoes similar instructions in previous, less lengthy versions.

The Civil Aviation Administration of China said the recommendation applies for charter flights to and from countries and regions where infections exceed 500 in every one million people.

The diaper advice is in a section on personal protective equipment, which also recommends the following for cabin crew:

Medical protective masks, double-layer disposable medical rubber gloves, goggles, disposable caps, disposable protective clothing, disposable shoe covers.

Flight crew should wear masks and goggles, but they don’t need diapers.

Other advice for the flights includes dividing the cabin into “clean area, buffer zone, passenger sitting area and quarantine area,” separated by disposable curtains.

The last three rows should be designated as an emergency quarantine area, CAAC said.

A group of 74 students checks in at Chongqing Jiangbei International Airport in October for a Hainan Airliines charter flight to Manchester, northern England.
