Rates of<unk>  differs depending on<unk>  and speed of ascent. In general, there is about a 0.2 to 6 percent incidence at , and about 2 to 15 percent at . The<unk> er incidence of 6% has been seen when climbers ascend at a rate > 600m/day. It has been reported that about 1 in 10,000 skiers who travel to moderate<unk> s in Colorado develop<unk> ; one study reported 150 cases over 39 months at a Colorado resort located at . About 1 in 50 climbers who ascended Denali developed pulmonary edema, and as<unk>  as 6% of climbers ascending rapidly in the Alps . In climbers who had previously developed<unk> , re-attack rate was up to 60% with ascent to in a 36-hour time period, though this risk was significantly reduced with slower ascent rates. It is believed that up to 50% of people suffer from subclinical<unk>  with mild edema to the lungs but no clinical impairment.
