Can you compare different countries? The revised official guidelines came after consultation with experts at universities in Zurich, Bern and Geneva, Swiss broadcaster SRF reported.
The new advice applies to young children who show no s of illness while older children must videochat roulette avoid contact with grandparents. Dr Koch advised only "brief contact with grandchildren", not family get-togethers, babysitting, or spending time with children outside the home.
However, not all experts concur with the Swiss government's findings. Sounding a note of caution, Germany's chief virologist Christian Drosten told Austrian broadcaster ORF that there was insufficient data to say conclusively that massachusdttes children could not transmit the virus. He said the question of whether children contracted the virus, and if so how they might pass it on, was answered differently in different studies.
Advice in the UK remains that children should not have contact with grandparents. At a daily news briefing this week, Health Secretary Matt Hancock was asked by a member of the public when she would be allowed to hug her grandchildren again.
Universitty Hancock said he "fully accepts" the sext bot of getting together with family but that it was important that "people who are vulnerable continue to be protected". The UK's chief medical adviser, Chris Whitty, has warned that for some vulnerable groups close contact with family may continue to be a risk for some time.
