The aim of this chapter is to draw attention to the importance of international standardization in tourism services with a view to the elimination of barriers to free movement of tourism services and its importance for consumers: visitors in tourism, when the international standards encourage consumers responsibility, enforce their legitimate demands, expectations, safety, and security. This contribution also describes the basic guidelines to prevent the spread of coronavirus in the tourism industry. These measures will contribute to the recovery of the tourism sector and restore the confidence of the traveler. Furthermore, the measures emphasize the possibilities of greater acceptance of international standards for tourism services in the post-COVID-19 period. They will also contribute to faster renewal of individual sectors/tourism services. At the same time, they contribute to reopening and engaging individual destination/countries in international tourism.
