Covid-19 has fostered a strong level of industry-wide collaboration in the effort to eradicate it.

In June, Royal Caribbean Group and Norwegian Cruise Line Holdings joined forces to form a Healthy Sail Panel focused on ensuring that health plans given to the US Centers for Disease Control and Prevention encapsulate best insights on health, science and engineering.

The group, which is led by former Utah governor Mike Leavitt and physician Dr Scott Gottlieb as co-chairmen, was due to offer initial recommendations by the end of August as an "open-source" collaboration.
