<div>In a new study by researchers in the UK, Germany and South Africa, this process is visualized using time-lapse microscopy of a human cell lung line, demonstrating that SARS-CoV-2 can induce cell-to-cell fusion within 6 hours post-infection. Further, the application of neutralizing monoclonal antibodies or convalescent plasma was unable to prevent the spread of the virus by this mechanism, suggesting that removing SARS-CoV-2 from cells permissive of cell membrane fusion could be more difficult than other types of cell.</div>
