Rebecca Zammit Lupi, a 14-year-old cancer patient, reaches out her little finger towards her father Reuters photographer Darrin Zammit Lupi, for a distant pinkie hug, through a fence, on a terrace at Sir Anthony Mamo Oncology Centre at Mater Dei Hospital, during the Coronavirus disease (COVID-19) outbreak, in Tal-Qroqq, Malta April 6, 2020. It was the first time they saw each other in three weeks, after the onset of the coronavirus outbreak meant that young cancer patients and one of their parents had to remain in lockdown at the hospital for several months. "I was very excited to see my dad through the fence. After countless video calls every night on my laptop, it felt great to see him in person, albeit from a bit of a distance! I had never been away from him for so long even though he tends to travel a lot," said Rebecca. Marisa Ford/via REUTERS SEARCH "REBECCA LUPI" FOR THIS STORY.
