The SARS-CoV-2 virus and the resulting COVID-19 pandemic has drastically changed the way we interact with each other. In a time of this salient pathogen threat, individual differences in how we avoid contagion become more visible. Research on disease avoidance behaviors showed that they are related to several individual characteristics, one of them being disgust sensitivity. Interestingly, disgust sensitivity to body odors in particular (body odor disgust sensitivity, BODS) has recently been studied in more detail and seems to be important for avoidance behaviors. This is understandable as olfaction helps in recognizing and evading the (often invisible) threat of disease. In this project, we used online surveys to investigated the relationship between BODS and disease avoidance during salient pathogen threat (COVID-19 pandemics). We collected data in three waves between April 2020 and June 2022, in various locations around the world. Wave 1 (N = 2068) was done in Italy and Sweden; wave 2 (N = 4595) in Canada, Chile, Hong Kong, Kenya, Nigeria, Mexico, New Zealand and the United Kingdom (UK); wave 3 (N = 2893) in Australia, Colombia, India, Italy, Nigeria, Sweden and UK. Participant completed the BODS questionnaire and answered questions about attitudes towards and concern about behaviors related to COVID-19 (e.g., wearing masks, avoiding contact with strangers etc.). We used Bayesian parameter estimation and model comparison to study the relationship between BODS and attitudes towards COVID-19. In all three datasets, participants who reported greater body odor disgust sensitivity were also more concerned about COVID-19 pandemics. Our findings support the idea that body odor disgust is relevant to disease avoidance by showing that it is related to attitudes about disease spread limiting behaviors during a salient pathogen threat situation. These studies were funded by the Swedish Research Council.
