The World Health Organization (WHO) has released travel advice amid concerns over the Omicron COVID-19 variant.

People aged 60 and over, or those who have not been vaccinated should postpone travel to areas where transmission is possible.

 Many countries have banned flights to the following countries: South Africa, Mozambique, Botswana, Zimbabwe, Lesotho, Eswatini, Namibia, Nigeria, Malawia and Egypt.

Any travelers who have traveled to these 10 no-fly countries in the past 14 days must quarantine at the hotel at the point of arrival. All international travelers, both vaccinated and unvaccinated, must be tested at the airport where they arrive. Then self-isolation is needed until the result is obtained for COVID-19.

In Russia, it is quite difficult to determine Omicron COVID-19, due to the fact that tests show only a positive or negative result for a common virus. It is possible to identify the Omicron COVID-19 strain only 2-3 days after collecting samples in specialized laboratories that work with this particular strain.
