Resumen
The main objective of this article is to develop a methodology to detect, assess and prevent biosecurity-related risks. Currently, the main risk found in our daily life is COVID-19, which has triggered a serious global pandemic. As a result, economic and social activity has suffered a decline in its development and evolution compared to previous years. All activity has come to a standstill and we are in a process of improvement that needs time. With the help of this methodology, focused on cruise traffic, it will be possible to identify the greatest existing threat and the process by which this high level of risk occurs. Once identified, a series of measures can be proposed to mitigate and prevent the risk, in order to make the port a safer place. The main aim is to recover cruise traffic as soon as possible, as it makes an important contribution to the tourism sector and to the cities and countries where cruise ships call.
