1. A system comprising:
an arch-shaped air outlet configured to couple to a first region of a bed and to provide air to generate an arch-shaped air curtain, the arch-shaped air outlet comprising an air outlet port arranged along the arch-shaped air outlet, wherein the system further comprises a space between the arch-shaped air curtain and the bed, wherein the arch-shaped air curtain and the bed form a substantially complete enclosure, and wherein the arch-shaped air outlet is configured to allow access to the space between the arch-shaped air curtain and the bed through an inside of the arch-shaped air outlet;
an arch-shaped air inlet configured to couple to a second region of a bed and capture air from the arch-shaped air curtain and from outside of the arch-shaped air curtain, the arch-shaped air inlet comprising an air inlet port arranged along the arch-shaped air inlet, wherein the arch-shaped air inlet is configured to allow access to the space between the arch-shaped air curtain and the bed through the inside of the arch-shaped air inlet;
one or more air outlet conduits coupled to the arch-shaped air outlet;
one or more air inlet conduits coupled to the arch-shaped air inlet;
one or more devices that motivate air flow, coupled to the air inlet conduit and the air outlet conduit; and
a filter or pathogen deactivation unit coupled to the air outlet conduit configured to reduce pathogens in the air flowing through the air outlet conduit;
wherein an air flow out of the arch-shaped air outlet is less than an air flow into the arch-shaped air inlet;
wherein one or more of a portion of the first region of the bed and a portion of the second region of the bed is between a head of the bed and a foot of the bed, wherein the bed comprises four sides comprising the head, the foot, a first side extending from the head to the foot, and a second side, opposite the first side, extending from the head to the foot.
