Interesting new Lassa virus lineage out of Togo. Is this a recombinant? https://wwwnc.cdc.gov/eid/article/24/3/17-1905_article …pic.twitter.com/sa4eHWS9Pi

Fascinating if true, given the -ssRNA genome. Divergence levels are pretty high, but a very quick NJ tree + counting nt differences do seem to suggest a recombination-y signal.pic.twitter.com/PAAi7U11Gy
I say recombinant, but that's just me being an idiot - what I meant was a reassortant 
. The former is pretty unlikely, the latter plausible given the bipartite genome.

Figure shows evidence of reassortment, yes, but it's noisy for GPC and NP trees. Those should have been combined into a single tree.

Yup, makes more sense to look at segments individually (to test for reassortments) - unless you have reason to believe recombination could have occured (we see very little / no evidence for that in our 2015 paper)
