Worldwide situation. General considerations
The WHO (World Health Organization) announced the end of the Coronavirus health emergency on May 5, 2023. However because the virus is still in force, it is convenient to review some tips before boarding. See current country restrictions.
Due to the advancement of vaccination worldwide, documentation and testing restrictions have been eliminated in many countries. In fact, in several countries they no longer even ask for a vaccination certificate, but still, there are a few countries that request the vaccination certificate or the affidavit of health or some antigen test or RT-PCR.
Therefore it is always important to ask and arrange details with the airline and, if necessary, with the Newark New Jersey airport (EWR)
as well as, in the case of international flights, with the embassy or consulate near the final destination, and also with the countries involved for connecting flights, if any.
