The new Covid variant of Omicron is currently spreading rapidly around the world.
At present, patients have been identified from five of the world’s most populous continents, and the number of countries where patients have been diagnosed has risen to 24.
In the past 24 hours, Omicron infections have been identified in Brazil, South America, as well as Nigeria, Norway, Ireland and Saudi Arabia.
All of these infected people have returned to their home countries after visiting African countries.
The World Health Organization (WHO) has advised people over the age of 60 who have not received the Kovid vaccine to avoid traveling to countries where there may be a social outbreak of omicron.
The organization says it also applies to adults with chronic non-communicable diseases.
They also point out that the spread of the new variety from country to country cannot be controlled simply by imposing large-scale tourism restrictions targeting countries.
The World Health Organization (WHO) warns that such restrictions could discourage countries from making new discoveries about the epidemic, which could lead to global health catastrophes.
