This article from BBC News shares the story of one family from Pakistan who came to the UK to seek medical treatment for one of their children, leaving their eldest son behind with his grandmother in Pakistan. The grandmother later became ill and placed the boy in an orphanage where he is now "stuck" due to the COVID-19 pandemic.
"The family had been desperately trying to get him a visa [to bring him to the UK], but all the offices have been closed due to the pandemic," says the article. "We are hoping that someone will do something and take him from that place," said the boy's father. "There is no possible way of social distancing, there are hundreds of children. They are already three times over the capacity."
