This is really important, especially in countries where flu season is coming.
At the same time, I’ve been reading papers in top journals about various clever technologies to do rapid (ie <60 minutes) detection of pathogens for years. The latest was using crispr [1]. None of them seem to have left the lab, PCR is still it.
Final point, nanopore sequencers are ideal for rapid home testing, and you get the actual sequence. They are a bit too expensive unfortunately.
