In Greece’s refugee camps, when Aaminah put infrared thermometers to the children’s foreheads, she was shocked to see them scream and drop to the floor.

“We realised it was making them think of a gun to the head," she says. "We had to demonstrate by putting the thermometers on our own heads first to calm them down."

Aaminah is a doctor based in London who volunteered for us several times in 2015 and 2016, working in refugee camps in Slovenia and Greece and providing vital healthcare for people fleeing conflicts in the Middle East.

Europe's refugee crisis started to gather momentum three years ago and remains a huge humanitarian emergency - there are currently 63,000 refugees in Greece alone. Doctors of the World works in several camps across Greece to provide comprehensive primary healthcare, including mental health and sexual health services.

During Aaminah's three-month stint on the Greek island of Chios, where people would arrive on dinghies to seek safety in Europe, she saw patients aged between five months and 84 years. One of her patients was a 13-year-old boy in a wheelchair. “Every person I met had lost someone they loved," she says.

Many of Aaminah's refugee patients showed acutely psychotic symptoms, as they started to process everything they had been through. “I dealt with seven psychiatric emergencies in less than three months" she says. "One woman tried to commit suicide three times."

Our work in Greece, and in refugee camps across Europe, is made possible by volunteers like Aaminah. You can watch a video about her time in Chios here and read her blog about her stint in Slovenia here.
