From: A new long-term sampling approach to viruses on surfaces
(A) The number of positive findings of eight sticker values and swab values determined by plaque assay from four independent experiments performed in duplicate. Virus titer concentrations ranging from 108 to 104 were used for artificial, direct contamination of paper-based stickers and routine cotton swabs. (B) The quantification of artificially contaminated plain-paper stickers (n = 32) with virus P100. The sampling material was contaminated with known virus titers ranging from 108 to 102 PGN/100 µL to cover a broad recovery range. The x-axis plots the inserted quantity of viral genomic matter (PGN/100 µL) and the y-axis plots the recovered viral genomic matter from respective sampling materials.
