What the world knows about his protest and the toll it has taken on his health is thanks to the courage of fellow prisoners at the Combinando del Este prison in Havana who have been able to provide information to Martinez's colleagues at the Hablemos Press news agency (CIHPRESS).
In retaliation, prison officials have started retaliating against other prisoners they believe are responsible for the leaks, according to a new report from CIHPRESS.
Political prisoner Jorge Bello Domínguez said prison officials have denied him needed medical care.
"The guards have told me that counter-revolutionaries don't deserve medical care," Bello said. "The increased repression against me is related to the information I am offering on the health of journalist Calixto Ramón Martínez Arias."
Other sources have asked CIHPRESS to not reveal their names, according to the latest report.
