The Dead & Company planned to headline the massive Playing In The Sand beach front festival in Cancun, Mexico this weekend even though drummer Bill Kreutzmann had to drop out due to a heart condition got scuttled with the news that guitarist John Mayer tested positive for COVID-19.  That development led to the group deciding it couldn't perform at the opening weekend (1/7-10). Shortly after that, it was announced that the entire event was being called off "...due to additional COVID-19 cases amongst multiple artists and staff".  While refunds for the festival itself will be arranged, many of the thousands already there or en-route will probably be out the costs for hotel rooms and flights unless they secured 'for any reason' cancellation insurance.
