A Tamarindo massage by a masseuse wearing a mask gives you peace of mind while you enjoy your massage. Similarly, wear one yourself for even more protection. Also, it's a good idea for both you and your masseuse to get your massage outdoors, or in a room with good air-flow. In any case, I wouldn't be too worried as we are not aware of a single case of COVID-19 anywhere in the area! So, relax and enjoy your massage your auto-immune system will lover it.
