Medical care in Romania is generally not up to Western standards, and basic medical supplies are limited, especially outside major cities.
Romania's currency is the "leu" (plural "lei") (it means "lion" in Romanian). It is the descendant of a Dutch currency that was used in this area in the 17th century.
Most visits to Romania are trouble-free but you should be aware of the global risk of indiscriminate international terrorist attacks, which could be against civilian targets, including places frequented by foreigners.
