This study, involving 51 people, evaluated a PCR method, which detected viral genomic material within 35 nasal swabs taken from personnel after up to eight hours exposure to infected animals. Only one of 23 people who was PCR-positive immediately after exposure to FMDV-infected animals remained positive the following day, indicating a low risk of prolonged carriage of virus in the nasal cavities.
