    The outbreak and spread of infectious and contagious diseases such as Covid-19, which is currently affecting the world population, especially Ecuador, highlights the inadequate handling of regulations regarding biosafety measures such as personal and object disinfection everyday use in a home. The objective of the research is to develop a mechanism that allows the continuous disinfection of a bathroom, through the application by spraying of disinfectant chemicals that are not harmful to health and thus guarantee a healthy home for the occupants, reducing the risk of contagion of diseases. intestinal and respiratory; and at the same time offering a comfortable method of disinfection. Methodologically, the sampling was carried out on surfaces of 6 houses of interest at the level of the home bathrooms in Cuenca - Ecuador, using swabs. Stuart medium was used to transport the samples. Bacterial identification was carried out using the semi-automatic RapID one method and conventional biochemical tests to determine the existence of pathogens. In addition to conducting a review of the state of the art for the selection of the best disinfectant and in turn the appropriate disinfection mechanism. Among the results obtained, the presence of pathogens is observed in the following percentages, 55% Escherichia coli, 18% Proteus mirabilis, 15% Enterococcus faecalis, 5% Klebsiella aerogenes, 5% Staphylococcus coagulase negative and 2.5% Morganella morganii in the different areas of the bathrooms where the samples were collected. The best disinfectant is determined to be quaternary ammonium used by means of a mist disinfection mechanism. The presence of microorganisms in areas that are used on a daily basis has consequences for the health of the inhabitants, for this reason, it is advisable to use quaternary ammonium to carry out the disinfection mechanism by nebulization, which is capable of eliminating 99.9% of these agents, guaranteeing a healthy environment without causing damage to its habitual occupants.
