Most Hii regions emit large amounts of energy at infrared wavelengths. Dust grains absorb a major fraction of the total energy emitted by the O stars, and this is reradiated in the infrared. The dense Hiicondensations seen by aperture synthesis radio observations are strong 20-µm infrared sources. The dust is probably mixed with the ionized gas in these sources. There are also infrared sources that are not radio sources; these may be protostars. Infrared emission has also been found from many OH/H2O maser sources associated with Hiiregions.
