GENEVA, Oct 30 (Reuters) - COVID tests should be more widely
used in international travel than quarantines, the chair of the
World Health Organization's Emergency Committee, Didier Houssin,
said on Friday.
Top emergency expert Mike Ryan earlier said that travelling
was now "relatively safe" with a "relatively low" risk.
He also said it was difficult to do scientific work on the
origin of the virus, first identified in China last December, in
a "politically toxic" environment.
