On April 3, 2020, Cross confirmed through his Facebook page that he had tested positive for the COVID-19 virus, and was ill, but is recovering. Cross later reported on Twitter that he has lost the use of his legs, but his doctors have told him he should fully recover. Physicians told him his COVID-19 disease triggered an episode of Guillain–Barré syndrome that caused the nerves in his legs to stop functioning properly. On October 18, 2020, during an interview with CBS Sunday Morning, Cross described what COVID-19 is like for him, in his first public appearance since contracting the virus. The effects of COVID 19 still linger as Cross considers himself a "Long Haul" survivor. Cross advocated the wearing of masks and is eager to tour again.
