Passengers on public transport systems should avoid talking to one another or on the phone in order to minimize the risk of spreading COVID-19, the French National Academy of Medicine said.
“The mandatory wearing of masks on public transport, where social distancing is not possible, should by accompanied by one very simple precaution: avoid talking and making phone calls,” the academy said in a statement.
Academy member Patrick Berche said on BFM TV on Saturday that talking is fine if the car is nearly empty, but if passengers are tightly packed, they should not converse or talk on the phone.
“It is not an obligation,” he said, “it is a recommendation.”
The academy is not an official advisory body. It can respond to government questions but also issues recommendations, which sometimes go against official policy.
The academy, which was founded in 1820, criticized a recent government recommendation to wear only surgical masks in public, rather than masks made of fabric.
“The proposed tightening of regulation (on masks) is based on a precautionary principle but it lacks scientific proof,” the academy said.
It said that fabric or homemade masks are efficient against the spread of COVID-19 as long as they are worn correctly, and that most infections occur in situations where people take off their masks.
“Such a change in recommendations concerning a practice with which the entire population had become familiar, risks sparking incomprehension and could revive doubts about the soundness of official policies,” the academy said.
