Rapid responses are electronic comments to the editor. They enable our users
to debate issues raised in articles published on bmj.com. A rapid response
is first posted online. If you need the URL (web address) of an individual
response, simply click on the response headline and copy the URL from the
browser window. A proportion of responses will, after editing, be published
online and in the print journal as letters, which are indexed in PubMed.
Rapid responses are not indexed in PubMed and they are not journal articles.
The BMJ reserves the right to remove responses which are being
wilfully misrepresented as published articles or when it is brought to our
attention that a response spreads misinformation.
From March 2022, the word limit for rapid responses will be 600 words not
including references and author details. We will no longer post responses
that exceed this limit.
The word limit for letters selected from posted responses remains 300 words.
But with a contact tracing App it should be possible to work out both prodromal infectious status and subsequent infectious profiles.
The data might also address the ‘random’ choice, as taken in Australia, to notify contacts >15 minutes of joint location.
The sub 15 minutes contact group warrant some follow up, and perhaps density of contact can be integrated with location and transmission rates?
The anecdote that one football match in Italy served to distribute covid19 widely might also be useful to research; not least as we plan to strategically step out of lockdown into a brave new world. One where the public domain will be managed very differently from the public omnibus, train, street, clubs, and public houses to stadiums!
There will then be some science to give the answers needed, beyond empirical personal space, air volume exchange rates, and metro air filtration.
There is much work to be done, and the standards being set now in Italy for public transport will be useful to research with these new contact Apps and outcomes.

I suspect the answer is in the press.

Busy times, and academically exciting.
