journals that publish urgent topics
Some journals are known for rapid publications, e.g. PeerJ (30 days to first decision). Some publishers offer various venues for &quot;accelerated publications&quot;, e.g. this list at Taylor &amp; Francis. There is another list here.
In general, you could simply ask the editor of any journal from your domain beforehand whether they would grant you an exceptionally speedy submission process for reasons pertaining to an emergency issue. It is possible that they will consider such a request.
