What is it about?
The best anatomical sites for collecting COVID-19 test samples were found to be the nasopharynx and nostrils in our comparison study. We evaluated the performance of saliva, nostrils, throat swab, and the usual standard nasopharynx. Patients themselves collected the saliva and nostril samples.

Why is it important?
The study showed the technical feasability of using different parts of the anatomy for sample collection. The nasopharynx cannot always be accessed for sample collection so it is important to know that alternative sites can be used.
Perspectives
Navigating the rapidly changing knowledge of the disease, while providing fresh data and insights for the scientific and policy community to make informed decisions, was challenging.
