Hot tub lung machine.

Published in: Respirology case reports (2020)
Hot tub lung (HTL) is a pulmonary disease where a hypersensitivity pneumonitis is caused by exposure and inhalation of aerosolized non-tuberculous mycobacteria (NTM) traditionally from hot water steam. HTL can affect both immunocompromised and healthy individuals, and diagnosis is dependent on high clinical suspicion in conjunction with high-resolution computed tomography (HRCT) and microbiological evidence. We present, to our knowledge, the only case of HTL occurring from an indoor swimming pool affecting five members of a family, in which one member was not a resident of the household.
