Not taking any chance of being infected by any type of airborne diseases, all aircraft inbound from international destination will be sprayed by disinfectant.
This picture just to show you one of the aircraft at the Heathrow airport being sprayed for disinfection. Upon arrival, all passengers are required to stay on their seats for some time to allow ground crews to carry out the disinfection processes. I just wondering how much the airport charge airlines for the disinfection processes. The disinfection process will reduce the chances of any diseases from spreading.
