A virus detection system is provided for receiving electrical signals that change quantitatively based on an amount of virus, via a communication line, from a measuring device equipped with graphene sensors that output the electrical signals that change quantitatively based on the amount of virus contained in samples collected from subjects and that associate the electrical signals with identification information for each subject. The virus detection further analyzes the amount of the virus contained in the samples collected from each of the subjects based on changes in the electrical signals outputted from the graphene sensors; and sends, via the communication line, analysis results on the amount of virus contained in the samples collected from each of the subjects to the communication terminal pre-registered to each subject.
