Question: Is it more dangerous to use public transport to a big event?

Answer passage (source: WHO):
page_title: Q&A: Mass gatherings and COVID-19
section_headers: How large does a meeting or event need to be in order to be a “mass gathering”?
section_content: High profile international sporting events such as the Olympics or World Cups
as well as international religious events such as the Hajj count as mass
gatherings. However, lower profile conferences and events can also meet WHO’s
definition of a mass gathering. An event counts as a “mass gatherings” if the
number of people it brings together is so large that it has the potential to
strain the planning and response resources of the health system in the
community where it takes place. You need to consider the location and duration
of the event as well as the number of participants. For example, if the event
takes place over several days in a small island state where the capacity of
the health system is quite limited then even an event with just a few thousand
participants could place a big strain on the health system and then be
considered a “mass gathering” event. Conversely, if the event is held in a big
city in a country with a large, well-resourced health system and lasts just a
few hours, the event may not constitute a “mass gathering” event.

Reviewer feedback on this answer:
Discusses mass gatherings, but doesn't specify whether mass transportation is safe.
This answer is bad because it doesn’t talk at all about the risk of using public transport, but rather just the risks of mass events in general. Therefore, the answer does not answer the question.

Answer passage (source: WHO):
page_title: Q&A: Mass gatherings and COVID-19
section_headers: Should event organizers arrange screening at venues beyond national government requirements for point of entry (PoE)?
section_content: Temperature screening alone, at exit or entry, is not an effective way to stop
international spread, since infected individuals may be in incubation period,
may not express apparent symptoms early on in the course of the disease, or
may dissimulate fever through the use of antipyretics; in addition, such
measures require substantial investments for what may bear little benefits. It
is more effective to provide prevention recommendation messages to travellers
and to collect health declarations at arrival, with travellers’ contact
details, to allow for a proper risk assessment and a possible contact tracing
of incoming
travellers.
Event organizers should also consider the capacity to undertake this and the
management of suspected cases. However, sporting organizations may have
criteria for participation that are stricter than government requirements for
Ports of Entry into the country that are based on event risk assessment,
including organizers' healthcare capacity.
Any additional screening questionnaires for participation in events need to be
aligned with public health agencies in the jurisdiction. There is a need to
consider how to manage different groups – athletes, officials and spectators,
and the large numbers of individuals likely to arrive at a sporting event from
many oversea countries – and to follow both host country and WHO travel
advice and to
assess whether there is difficulty in obtaining accurate information about the
travel history of those individuals.

Reviewer feedback on this answer:
Discusses how to safely hold mass events, but doesn't specifically mention mass transit.
This answer is bad because it talks about entry points at stadiums and mass gathering events, but doesn’t talk at all about public transportation risks to and from these events.

Answer passage (source: WHO):
page_title: Q&A: Mass gatherings and COVID-19
section_headers: What are the risks arising from public transport to the venue(s)?
section_content: The extra risk from participants and spectators travelling on public transport
in a major city may not be significant compared to the ongoing risk to the
local population using the transport all the time if physical distancing is
not possible on public transport.

Reviewer feedback on this answer:
Specifies that mass events don't increase the existing risk from mass transit.
This answer needs improvement because although it relates to the question, it is vague and needs more details to really answer the question.
