Virus survival on nine fomites at room temperature (RT) and at 4 °C. PEDV was applied on fomite materials or in control wells followed by storage at RT (▲) or at 4 °C (■). The surviving virus was eluted after various time periods and titrated. Decay of infectious virus was rapid at RT but delayed when stored at 4 °C. Black dotted line represents detection limit of TCID₅₀ assay, which is 2 × 10² TCID₅₀/mL. Data presented are average of three values (± SEM) obtained from independent assessments at each time point indicated.
