Anyone planning a trip overseas should always check the travel advisory for their destination country for any restrictions on entry, quarantine requirements on entry, or other relevant travel advice.
In addition to taking standard travel precautions, and in order to avoid being quarantined or denied re-entry into your home country, you are also advised to check the latest COVID-19 update on the International Air Transport Association website, which includes a list of countries and restriction measures.
While traveling, all parents should follow standard hygiene measures for themselves and their children: Wash hands frequently or use an alcohol-based sanitizer with at least 60 per cent alcohol, practice good respiratory hygiene (cover your mouth and nose with your bent elbow or tissue when you cough or sneeze and immediately dispose of the used tissue) and avoid close contact with anyone who is coughing or sneezing. In addition, it is recommended that parents always carry a hand sanitizer, pack of disposable tissues, and disinfecting wipes.
Additional recommendations include: Clean your seat, armrest, touchscreen, etc. with a disinfecting wipe once inside an aircraft or other vehicle. Also use a disinfecting wipe to clean key surfaces, doorknobs, remote controls, etc at the hotel or other accommodation where you and your children are staying.
