What is the evidence for droplet transmission for SARS-CoV-2?

A guest post from Dr Evonne Curran

The disputed airborne mode of transmission in this pandemic requires further scrutiny. Researchers have thus far focused on presenting a case for airborne transmission1 rather than disputing that the ‘primary’ mode of transmission for SARS-CoV-2 is via droplets2.

Can you GES which carbapenemase caused this CPE outbreak?

An unusual and interesting outbreak of CPE was published recently in Clinical Infectious Diseases. Several key points: don’t rely solely on a PCR detecting the “Big 5” carbapenemases (NDM, KPC, OXA-48, IMP, VIM) – at some point you need to test for phenotypic carbapenemase activity; WGS can really help us in unravelling complex transmission routes; and covert plasmid propagation within and between species is a reality.
