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.
Not clear if triggering the app to report symptoms automatically leads to a test?
One assumes it would or we could have a large number of people repeatedly self isolating for 2 weeks without knowing if anybody is ill with covid. Please can this be clarified.
We are not yet being told what percentage of tests are positive, what is thought to the the false negative rate and how many are asymptomatically spreading from pyramid 4 data.
