(Reuters) — The World Health Organization (WHO) said on Monday it expects to get more detail soon on the potential impact of a new coronavirus strain, as a slew of countries closed their borders to Britain over fears about its spread.
There is no evidence the mutated variant of the virus increases the severity of the disease, although it is more transmissible, WHO top emergency expert Mike Ryan said, citing UK analysis.
Maria Van Kerkhove, WHO technical lead for COVID-19, said scientists are looking at the body’s antibody response to the virus and she expects results in the coming days and weeks.
At the briefing, Ryan said countries were acting out of a “precautionary principle” in reaction to the variant and said that was “prudent”.
The announcement on Saturday evening by UK Prime Minister Boris Johnson prompted countries across Europe and around the world to close their borders to the UK, over fears that the new strain could spread further.
