Whether sex and gender matter to clinical pathways and outcomes associated with COVID-19. Analyses of data, and among 20 countries, it was found that:
- Six provide sex-disaggregated data for numbers of confirmed cases and deaths (China, France, Germany, Iran, Italy, South Korea)
- Seven provide sex-disaggregated data for numbers of confirmed cases only (Austria, Canada, Denmark, Japan, Norway, Sweden, Switzerland)
- No sex-disaggregated data could be located for eight countries (Belgium, Malaysia, Netherlands, Portugal, Spain, United Kingdom, United States of America), although both the Netherlands and Spain informed us that they were in the process of compiling sex-disaggregated data but they were not available at the time of reporting.
- Explanations focus on the immune system and underlying illnesses.
