Therefore, during my whole time at the AIRPORTS, I have never removed my MASK and my FACE SHIELD, I have always kept my distance from other people, especially in queues, and I refrained from going to the toilet because the aerosol spray from the flushes could spread the virus in the air.
I just went to the toilet at the AIRPORT only one time, in São Paulo, so I made sure to be wearing sunglasses to protect my eyes, washed my hands thoroughly, and disinfected my handbag with SANITISER after leaving the restroom.
I must stress out that the boarding and disembarking queues were very well-run in all flights with proper SOCIAL DISTANCING, except when I arrived in Brasília, where the passengers were all huddled in a bus to go from the AIRPLANE to the AIRPORT.
By the way, talking about AIRPLANES, I have discovered in my research that the air within the aircraft cabins can be cleaner than an operating theatre due to the HEPA FILTERS.
Indeed, HEPA is an acronym for HIGH-EFFICIENCY PARTICULATE AIR and these filters can capture 99.5% of all particular pollution, including viruses and germs.
Besides it, the ventilation system of most aircraft allows the air of the cabin to be completely renovated every three minutes with a blend of filtered air with fresh outside air.
This was surprisingly good news because they meant that the aircraft cabins’ were not as dangerous as I was expecting them to be.
However, it must be highlighted that the WHO states that "adequate ventilation is just ONE of the preventive measures", which means that other measures like SOCIAL DISTANCING, wearing MASKS and other PERSONAL PROTECTIVE EQUIPMENT (PPE) and HAND HYGIENE should also be adopted.
In my case, I have travelled wearing a MASK (which was demanded by all airlines I have flown with during this trip) and a FACE SHIELD, which I have only removed to eat.
