Background Respiratory hygiene, especially in context of COVID-19, is of upmost importance. Healthcare professionals (HCPs) play an important role in the prevention of infections. Their perceptions of the subject are needed to tailor effective communication and training on prevention. Methods 20 French HCPs were questioned about their perceptions on respiratory hygiene and infections, by the means of recorded semi-structured interviews and a focus group. The interviews and focus group were transcribed then analysed through lexicometric and thematic content analyses. Results HCP discourse revolved around the use of face masks, the prevention and the characteristics of respiratory infections and the means to prevent them.COVID-19 excepted, HCPs considered respiratory infections as benign. They associated respiratory hygiene to the observance of cough etiquette, the preservation of lung health, the act of protecting oneself and others, and the adherence to safety protocols. Main barriers to good practices were organizational ones, such as the lack of consultation and mobilization of HCPs in the development of preventive measures, suboptimal information sharing and the physical and relational constraints of face masks. They advised means of improving communication and information promotion. Conclusion Since the pandemic crisis, HCPs have developed a better awareness about the prevention of respiratory infections. Except for COVID-19, respiratory infections are mostly considered as benign. Barriers and facilitators evoked by HCPs will help to build national communication and tools.< Réduire
