Muzaffer Kayasan, a resident of Istanbul, has been in quarantine for more than a year and during this time passed 78 positive tests for COVID-19. The man contracted the coronavirus in November 2020. Since then, he has been regularly tested for infection, and each time the test comes back positive for COVID-19. Doctors attribute this to the fact that the man has leukemia, so his immune system is weak. Most of all, Muzaffer Kayasan is upset because he cannot see his grandchildren and because of such a long isolation, both he and his family suffer, reports mir24.tv.
