I’m unsure how this links to Italian behaviour being different from ours. Unless you are aiming at continental embraces to say hello - in which case again that makes our statistics here worse by comparison.

So how many of those with the virus have been coughed or sneezed upon? With the group in the Peak District who had a picnic and used a shisha, if just one of them has the virus, they WILL ALL have it now. They will now return to their homes and likely congregate in groups and use a shisha, and they WILL ALL also get it. Just an example of why the transmission via saliva need highlighting. Things like shouting and speaking are likely to spread saliva droplets.
From the past the evidence is that enclosed spaces are a huge factor, especially ships. That would include offices and hospitals. It's not unlikely that merely breathing helps spread it.
Impact of mass gatherings on an influenza pandemic

In conclusion there is limited data indicating that mass gatherings are associated with influenza transmission and this theme is continued with the inclusion of new evidence for the update. Certain unique events such as the Hajj, specialised settings including civilian and military ships- a new theme for this update, indoor venues and crowded outdoor venues provide the primary evidence base to suggest mass gatherings can be associated with Influenza outbreaks. Some evidence suggests that restricting mass gatherings together with other social distancing measures may help to reduce transmission. However, the evidence is still not strong enough to warrant advocating legislated restrictions. Therefore, in a pandemic situation a cautious policy of voluntary avoidance of mass gatherings would is still the most prudent message. Operational considerations including practical implications of policy directed at restricting mass gathering events should be carefully considered.
