Upon arrival in ZZZZ; we experienced some health and safety concerns.  Everyone that interacted with us was in full PPE but the most concerning part was we were followed by a guy that sprayed some chemical into the air around us.   Some type of fogging machine - no idea what the chemicals were.   They even had another person spray a liquid chemical onto the floor after we walked through customs.  (That was the only point where we were actually inside a building).   They transported us in an airport bus that also had a strong chlorine smell to it.Arrival at the hotel was like a scene from the movie Outbreak.   The entire inside of the hotel is drenched in a white powder substance (probably from fogging) and carpets/floors haven't been cleaned or vacuumed in weeks.  Room floors were covered in dust; lint; and other crumbs. Trash bags were all over the hotel hallways.  To add to the chemical list; we were even given chlorine tablets to drop in the toilet prior to defecation.Food was delivered to the room as you were not allowed to leave your room during the entire stay.  Although we were supposed to have set times for food drop-off; it was never consistent.   Coordinating your international sleep around their food delivery was impossible.   Some people like to sleep upon arrival at XA:00 pm to catch some of your previous WOCL - in that case your dinner sits outside and potentially spoils.I'm writing this report a couple days later as I still have a slight sore throat that developed during the layover.   The Captain has had similar symptoms along with congestion.   It's unlikely we contracted COVID as we all tested negative the morning of that trip but do think it could be related to all the chemical/cleaning agents they used around us.
Air carrier First Officer reported multiple concerns with the COVID-19 sanitizing protocols used at the layover airport and hotel in a foreign country.
