We've all seen the news of desperate migrants trying to cross the channel. But few people know about the conditions people are living in. This is a humanitarian crisis on our doorstep and western governments are turning their backs on it. I know because I’m a nurse in Calais, giving medical support to migrants who have fled their countries because of war and persecution and are now living in horrendous conditions. Whole families are crammed into small tents with poor access to food and water, leading to all sorts of terrible health problems. These include serious skin problems, gangrene, breathing difficulties, diarrhoea and scabies. Many have shattered bones after falling from trucks, have been slashed by razor wire climbing fences or have been beaten up. Some are extremely vulnerable, including children and pregnant women. With needs ever increasing, it is charities and not governments that are picking up the pieces, providing essential medical consultations and psychological support for the many migrants traumatised by their experiences.
