Bloomsbury is the latest publisher to confirm it will not be at the physical book fair at Frankfurt in October.
In a note to colleagues, c.e.o. Nigel Newton said: "Bloomsbury intends to participate in the virtual but not the physical book fair. This flows from the consistent application of our policy of putting staff welfare first and as October is the cusp of the flu season and a possible second spike of the coronavirus, I think it would be inadvisable for Bloomsbury to send people by plane, train, bus or car to an international trade fair.
"But we are good at doing things virtually and I am sure we will sell many rights and acquire books in the new way."
Bloomsbury joins HarperCollins, Pan Macmillan and Macmillan US, Bonnier Books UK and Simon & Schuster in withdrawing from the physical event, with many German publishers also saying they will not exhibit this year.
