British pilot no longer suffers COVID-19
A 43-year-old British pilot, who was once Vietnam’s sickest coronavirus patient, was declared completely free of COVID-19 on Monday evening.
He was admitted to the Ho Chi Minh City Hospital for Tropical Diseases with damaged lungs on March 18.
His conditions deteriorated shortly after that, putting him in a coma and his life in jeopardy a few times.
Doctors once thought only a lung transplant would save him from death.
But medication and other medical care gradually improved his health in the following weeks.
The Scotsman was transferred to the intensive care unit at Cho Ray Hospital on May 22, still comatose and with severely damaged lungs, after being cleared of the coronavirus following his treatment at the Ho Chi Minh City Hospital for Tropical Diseases.
He has waken up from the coma and made a marvelous recovery since, with his lungs nearly restored.
The patient was transferred from the intensive care ward to the physical rehabilitation unit of Cho Ray Hospital on June 21.
He is still in treatment at Cho Ray Hospital for his mobility functions to prepare for his flight back to Scotland on July 12.
Doctors say he can be discharged from the hospital with no quarantine needed.
