Five London bus workers have now died with Covid-19, according to a trade union.
The deaths were called a "terrible tragedy" by Unite and regional secretary Peter Kavanagh said the union will assist the family "in every possible way during this terrible time".
He said: “Unite has been working continuously with Transport for London (TfL) and the operators to ensure the safety of drivers and others in the industry who are performing a heroic job in getting NHS and care workers to their places of work.
“These measures include deep cleaning of buses, additional cleaning of touch points, the sealing of screens around the driver, the provision of hand sanitiser for all and placing the passenger seating closest to the driver out of bounds.
“I have been in direct contact with the Mayor of London who shares our view that bus drivers must be fully protected."
Mr Kavanagh said Unite is holding daily meetings with TfL to explore further safety improvements.
He added: "We are absolutely committed to doing everything in our power to make the driving of buses safe during this unprecedented crisis.
“We are also calling on the Government to make provisions for transport workers in terms of personal protective equipment.”
Transport for London has been approached for comment.
