Even though we’re in our 70’s we’re pretty fit so we don’t stress out about health issues when we travel. However, we do check with our Doctors to see what they recommend.
The other resource we use is Centers for Disease Control and Prevention. This site keeps up to date with health issues around the world and has recommendations for vaccinations and anti-malarial medications.
We always carry copies of our prescription medication as well as eye glasses or contact prescriptions – just in case we need to replace these. We’ve found in some countries, the pharmacies don’t need to see the prescriptions but are happy to renew your medicines if you show them the bottle, however, rather be safe than sorry!
