for all individuals travelling abroad it is an excellent idea to carry a safety card with you at all times, especially if certain medical conditions or religious beliefs need to be communicated - ahead of traveling, print out a small card with these details.

a local phone number
one emergency contact such as close friend or next of kin
nationality
consulate phone number and address
medical insurance plan information
pertinent medical conditions or relevant religious affiliations

for the highest level of effectiveness these details can be printed in both in english and in portuguese with one language on each side.
