A very rough start to Vietnam however one of the best countries we’ve seen with so much to do ,we loved exploring the slightly chaotic city of Hanoi but also the very relaxed and peaceful city of Hoi An
They’re only dangerous if the place doesn’t have proper hygiene practices and pre treatment checks in place. UV light filters make it low risk. It’s just feels like someone lightly tickling the bottoms of your feet if you can handle that? Have a great trip. 👍
