Ambulance staff are being put at risk by a lack of protective equipment to guard them against coronavirus, according to a trade union.

The BBC has received written statements from some paramedics who did not want to be identified.
One worker said: "Every day more of our colleagues are being struck down with high temperatures and other symptoms. I feel it's just a matter of time before it's my turn and then I could potentially take it home to my family.
"But if I was to be sent home the guilt would set in – my colleagues are out there dealing with this crisis unprotected and I wouldn't be with them."
Another said: "We take patients to hospital in flimsy paper masks, a plastic thin apron that flaps up in the slightest breeze and gloves. To see the level of PPE that hospital staff are wearing, compared to ours, Read More – Source
