The recent outbreak of Yellow Fever in Brazil has prompted changes to border requirements from a number of other South American countries, in an effort to stop the spread of disease. This includes countries who may previously have had no requirements at all or had restrictions based only on entry into the country and not on airport transit. Another example of things changing! Don’t be caught out at borders because you haven’t had the appropriate immunisations. Not only is it time consuming but it can also be costly. We recently heard of travellers who hadn’t seen a travel health specialist before going overseas and who were not allowed to board a flight from one South American country to another because they hadn’t had the Yellow Fever vaccination. They had to change plans and fly somewhere completely different instead. Costs included new airfares, non-refundable accommodation fees in one country and more accommodation costs in the new. Not covered by insurance.
