Increased #pathogenicity {in animal models} and #transmission of #SarsCoV2 #Omicron #XBB19 #sublineage, including #HK3 and #EG51, BioRxIV, https://www.biorxiv.org/content/10.1101/2024.06.10.598324v1?rss=1

HK.3 and EG.5.1 exhibited greater pathogenicity than XBB.1.9.1 and BA.2 in H11-K18-hACE2 #hamsters. Our studies provide insight into the newly emerging #pathogens HK.3 and EG.5.1.

-- En relación con la #Covid19, explicó en un artículo publicado en la página web del Minsap, que en los últimos dos meses del 2023 y los días transcurridos del 2024 se ha identificado principalmente la presencia de tres #subvariantes de #Ómicron: #XBB15, #XBB19 y #XBB116, clasificadas por la OMS como de interés o bajo vigilancia.
