Long-term survival of salmon-attached SARS-CoV-2 at 4 degree as a potential source of transmission in seafood markets

Several outbreaks of COVID-19 were associated with seafood markets, raising concerns that fish-attached SARS-CoV-2 may exhibit prolonged survival in low-temperature environments. Here we showed that salmon-attached SARS-CoV-2 at 4{degrees}C could remain infectious for more than one week, suggesting that fish-attached SARS-CoV-2 may be a source of transmission.
