A delusional man who was sexually disinhibited and thought he was on a TV show turned out to be suffering from what’s believed to be the first case of coronavirus-related psychosis, according to UK doctors.

The 41-year-old man presented to emergency in April with grandiose thoughts and in a highly aroused and sexually disinhibited state, report doctors from King’s College and Guy’s and St Thomas’ Hospitals in London.

The man had woken up feeling agitated, telling his wife he felt he was going to die. Thinking he was unable to lie or hide the truth, he disclosed to her homosexual encounters and “uncharacteristic” sexual behaviours.

While in emergency he inappropriately touched staff, tried to anoint other patients with water and obsessively wrote down every personal interaction and bodily sensation, the doctors wrote in BMJ Case Reports.
