The certificate of recovery must state the date of the first positive test, and indicate that the passenger has passed the disease and is not infectious-contagious at the present time, and the country where the certificate was issued. They may submit a certificate of recovery provided that more than 11 days have elapsed since the first positive NAAT test was performed. This certificate shall be valid for 180 days thereafter.
If it is not possible to obtain it in these languages, it must be accompanied by a translation into Spanish by an official body.
