Infectious respiratory particles exhaled by Clade IIb Mpox virus-infected macaques
copies/L respectively). Most virus-laden particles (from macaques and air within the isolator) were coarse particles (>7 μm); during peak viral emission, 94%-97% of exhaled particle viral copies and 87%-97% of air within the isolator ones concentrated here. Infectious viruses were present in the exhaled coarse particles of macaques and, in some cases, in particles from the air within the isolator, but not in fine particles. This study provides evidence supporting the airborne transmission of MPXV and suggests that respiratory coarse particles may play a more significant role than fine particles in driving this mode of transmission.
