This article lays out the perception of the odorous phenomenon, with the objective to inspire reflection concerning the significance of these phenomenon and their relationship with infectious processes in the hospital environment. A documental analysis was performed, searching the contents of 5503 Complementary Nursing Observations, referring to the perception of the Nursing Team before odorous situations, their interpretation through registration of the taxonomy of smells and decision-making procedures towards the 160 clients submitted to the Overnight Surgery Clinics in a University Hospital. The data show that of the 5503 observations, 2557 referred to odorous phenomenon, and of these, only 91 characterized the qualified odorous phenomenon, focusing on corporal secretions. In the hospital space, denial, occulting, and olfactory silence are evidenced. This, without a doubt, impedes the real evidence of the risk of infection. We recommend advancing the study and practice of bodily and environmental hygiene, as well as of the materials used in the health care services to promote health. We also recommend developing new conceptions and modalities of approaching olfactory perceptions, their sensations and implications in view of healthier living
