Eight out of 10 questioned said when they travel, they are very much concerned about viruses, bacteria and germs. Around 28 per cent consider aircrafts to be germy.

Cleanliness in airports, hotels and restaurants is also a major concern for people, and 55 per cent of respondents said that they wash their hands more frequently while travelling.

Besides this, many travellers carry their personal cleaning accessories, towels, sheets and shower shoes, with them when they are going out for a trip. Clean toilets are taken as a mark of a tremendous airport.
