There appears to be an association between asthma onset and exacerbation with cleaning and disinfecting activities in a number of industries, including healthcare

In March 2019 researchers from the USA published the results of their study to assess the association between asthma and related outcomes with occupations and tasks in healthcare workers in the United States. A total of 2,030 individuals were involved in the study. Information on post-hire asthma, current asthma, exacerbation of asthma and symptom wheeze was collected via a questionnaire, together with information on occupation and four healthcare tasks. Results showed that the task of cleaning fixed surfaces was significantly associated with current asthma, moderate exacerbation and symptoms of bronchial hyper-responsiveness. In comparison to nursing assistants, environmental service workers and registered nurses appeared to have a higher risk for current asthma, and licensed practical nurses a higher risk for moderate exacerbation.
