Eating before saliva collection may interfere with detection of SARS-CoV-2

A new study, published on the medRxiv* preprint server, has aimed to determine if children's diet impacts the detection of SARS-CoV-2 virus in saliva. Scientists performed diagnostic tests to detect this virus using real-time self-collected specimens provided by five healthy children. The samples were collected before and after eating selected foods. The specific time of collection of samples after eating were 0 minutes, 20 minutes, and 60 minutes after eating.
