Fighting the coronavirus pandemic is hard, in fact it seems impossible. Doctors, nurses, carers and paramedics around the world are facing an unprecedented workload in overstretched health facilities, and with no end in sight. They are working in stressful and frightening work environments, not just because the virus is little understood, but because in most settings they are under-protected, overworked and themselves vulnerable to infection.The risk to doctors, nurses and others on the front lines has become plain: Italy has seen at least 18 doctors with coronavirus die. Spain reported that more than 3,900 health care workers have become infected. In dire times such as these, people are trying their best to show their appreciation to the frontline workers. Here are some images -- from clapping for them to singing for them.. A 'thank you' in any way goes a long way around.
