The World Health Organisation has changed its guidance relating to the COVID variant Omicron, after initially saying over-60s and those who risk developing serious illness should postpone overseas trips.

WHO’s initial guidance, on 30 November, said: “Persons who are unwell or at risk of developing severe COVID-19 disease and dying, including people 60 years of age or older or those with comorbidities (eg heart disease, cancer and diabetes), should be advised to postpone travel.”

The guidance has since been updated to say non-vaccinated over-60s and those at risk should not travel to areas with community transmission.

WHO now advises: “Persons who are unwell, or who have not been fully vaccinated or do not have proof of previous SARS-CoV-2 infection and are at increased risk of developing severe disease and dying, including people 60 years of age or older or those with comorbidities that present increased risk of severe COVID-19 (eg heart disease, cancer and diabetes) should be advised to postpone travel to areas with community transmission.”

It adds: “In addition, all travellers should be reminded to remain vigilant for signs and symptoms of COVID-19, to get vaccinated when it is their turn and to adhere to public health and social measures at all times and regardless of vaccination status, including by using masks appropriately, respecting physical distancing, following good respiratory etiquette and avoiding crowded and poorly ventilated spaces.
