A Turkish man, who has been testing positive for 14 straight months, has Türkiye's longest recorded continuous Covid-19 infection, doctors say.

Muzaffer Kayasan, 56, thought he was destined to die when he first caught Covid-19, since he was already suffering from leukemia. 

Fourteen months and 78 straight positive tests later, he is still alive - and still battling to shake off the infection.

Doctors said Kayasan's situation is possibly due to a weakened immune system from the cancer.

Despite being in and out of hospital since November 2020, with nine months in hospital and five months mostly alone in his flat, his spirits have been high.

His prolonged Covid infection has separated him from much of the outside world, including his granddaughter, Azra, who stays in the garden while visiting, talking through the glass back door.

A "positive" person

Coronavirus patients with immunosuppression are at risk of prolonged infection with severe acute respiratory syndrome, according to a study published last year in the New England Journal of Medicine.

Another by the Leukemia & Lymphoma Society shows one in four blood cancer patients do not produce detectable antibodies even after receiving two vaccine shots.

Kayasan's doctor, Serap Simsek Yavuz, infectious diseases and clinical microbiology professor at Istanbul University, said his is the longest case they have tracked and it is being closely monitored for any risk of a mutated variant.

"The case of a patient testing positive for 441 days is not something that has been reported until today," said Cagri Buke, doctor of infectious diseases and clinical microbiology at Acibadem Hospital.

The positive tests make Kayasan ineligible for a vaccine, according to Turkish guidelines that say positive patients must wait for a full recovery to receive a shot.

Kayasan, who lost his sense of taste and smell through the ordeal, has appealed to authorities to at least ease his confinement.

His son, Gokhan Kayasan, said his father had always been a "positive" person - just not in this way.

"We kept saying how positive he is and now the guy turned positive (for Covid) and can't go back to negative," he said.

"He says he got stuck at the red light and can't pass that."
