A Study to Understand How the Use of Paxlovid Affected the Healthcare Use in People With Pre-existing Conditions.

This is a non-interventional medical chart review study aiming to examine the effectiveness, safety, and treatment patterns of isavuconazole in 5 European countries (France, Germany, Italy, Spain, and United Kingdom). Eligible patients are adults who have been treated with isavuconazole in routine practice at participating sites since 15 October, 2015 or since the date of launch in the country if it is after 15 October, 2015 until 30 June, 2019. As this is an observational study, patients will be treated based on the standard of care at the discretion of their physician. No drugs will be supplied for this study and patients will receive treatment through standard local practice.
