LONDON, July 29 (Reuters) - There is no silver bullet on
testing which could allow quarantine-free travel, British
culture minister Oliver Dowden said, responding to calls from
the boss of Heathrow Airport for more testing to boost travel.
"It's not the case that you can simply test somebody and be
sure that they don't have the disease. It can incubate over a
period of time so there's not a silver bullet of just testing
immediately at the border," Dowden told the BBC on Wednesday.
