The World Health Organization (WHO) calls for an essential 42-day monitoring period for all passengers on board. This step is taken as an effective pandemic response to identify and control the health condition of individuals exposed to the risk of a global outbreak. Details such as the methods of monitoring, specific transportation platforms, and timelines are yet to be disclosed.

Japan heavily depends on sea and air transportation for both domestic and international affairs. Consistent monitoring of traveler's health is an essential layer of protection for its densely populated urban areas. The call from WHO implies potential alterations in Japan's transportation and health policy that could affect its socio-economic aspects as well.

In the US and EU, disease control strategies revolve around strict health and safety measures as well. Presently, they rely on a short-term quarantine period along with symptomatic and a-symptomatic testing. A 42-day observation period would be a significant shift in approach if implemented.
