ABSTRACT
Background: the airplane environment presents special characteristics which include: dry air, high density of occupants,
and exposure to environmental microbiota. The transmission routes of infectious diseases on aircraft are
similar to transmission patterns in community settings.
Material and methods: a descriptive, observational study was carried out. The pH and chlorination of the water
were measured, Pur Test
® Home Water Analysis rapid tests and Testlab
® reagents were used. Water was cultured
using PurTest
® Home Water Analysis transport medium. Two tap water samples were taken from two bathrooms
inside the plane.
Results: in the sampled sites, alkaline pH predominated and there was no residual chlorine data. There was growth
of Bacillus cereus in the two sampled sites.
Conclusion: the purification of water through chlorination is essential in all regions; chlorine is a relatively cheap
and easily applied element.
