Hong Kong International Airport (HKIA) has provided a glimpse into what international airport procedures might look like once we're traveling again, and a lot of disinfection technologies are involved.
The busy Asia airport claims it's the first in the world to trial a live operation of CLeanTech, a full-body disinfection booth.
The short, but thorough, process sees those passing through undertake a temperature check before entering a small booth for the 40-second disinfection and sanitizing procedures.
According to the airport authority, the inside of the facility contains an antimicrobial coating that can remotely kill any viruses and/or bacteria found on clothing, as well as the body, by using photocatalyst advances along with "nano needles."
The individual is also sprinkled with sanitizing spray for "instant disinfection" inside the booth, which is kept under negative pressure, an isolation technique used in hospitals and medical centers, to prevent cross-contamination.
While CLeanTech is at present only being used on staff who undertake public health and quarantine duties for passenger arrivals, the fact that it's being trialed at one of the world's busiest airports suggests facilities like this may be used more widely in the near future.
However, it's worth noting that, as this system aims to disinfect a person's clothes and skin externally, it may not be effective when it comes to detecting those already infected with coronavirus who are not displaying any symptoms.
To help prevent person-to-person spread, many airlines are instructing people to wear masks.
Along with CLeanTech, the airport authority is also testing antimicrobial coating that will see an invisible coating which destroys all germs, bacteria and viruses being applied at all passenger facilities at Hong Kong International Airport.
This includes handles and seats, smart check-in kiosks and check-in counters, baggage trolleys and elevator buttons.
Once the trial is complete in May, a decision will be made on whether this measure will be implemented permanently.
Along with this, autonomous cleaning robots are being used to continuously disinfect public areas and passenger facilities at HKIA.
