In August 2009, the historic Typhoon Morakot brought extreme rainfall and resulted in flooding which spread throughout southern Taiwan. This study compared the difference between fungal concentrations before and after the disaster in selected homes of the Tainan metropolitan area, which were hit hardest by the catastrophe. A group of 83 households available from a prior cohort established with random sampling out of a regional population in southern Taiwan was contacted successfully by telephone. Twenty-five of these reported to have suffered from floods of various degrees at this time. Around 2 weeks after the event, at which time most of the remedial process had been completed by self-efforts and public health endeavours, 14 of these 25 (56%) agreed to participate in measurements of the airborne microbial concentrations. The averages (standard deviation) of the total culturable fungal concentrations in children's bedrooms and flooded rooms were 18,181 (25,854) colony-forming units per cubic metre (CFU/m(3)) and 13,440 (11,033) CFU/m(3), respectively. The airborne fungal spore levels in the 2 above-mentioned indoor sites were 221,536 (169,640) spores/m(3) and 201,582 (137,091) spores/m(3), respectively. The average indoor/outdoor ratios in the children's bedrooms were 4.2 for culturable fungi and 1.4 for fungal spores. These values were higher than the respective values measured in the same homes during the previous year: 1.1 and 0.6. In terms of the specific fungal profile, the percentages of Aspergillus spp. increased significantly in both the indoor and outdoor environments after the event. To this date, this study is among the limited research that has been conducted to quantitatively demonstrate that fungal manifestation is likely to persist in flooded homes even after seemingly robust remedial measures have been put into place. Studies to examine the potential health implications and effectiveness of better remedial technology remain much needed.
2009 年 8 月，历史性台风“莫拉克”带来了极端降雨，导致洪水泛滥，蔓延至台湾南部。本研究比较了受灾最严重的台南都会区选定家庭在灾害前后真菌浓度的差异。通过电话成功联系到了一组 83 户家庭，这些家庭是从台湾南部一个区域人群中随机抽样建立的一个先前队列中选出的。其中 25 户家庭报告说此时遭受了不同程度的洪水。事件发生后大约两周，大多数补救工作已经由自我努力和公共卫生努力完成，这 25 户家庭中有 14 户（56%）同意参与空气中微生物浓度的测量。儿童卧室和被洪水淹没房间的总可培养真菌浓度的平均值（标准差）分别为 18181（25854）个菌落形成单位/立方米（CFU/m3）和 13440（11033）CFU/m3。上述两个室内地点的空气中真菌孢子水平分别为 221536（169640）个孢子/m3和 201582（137091）个孢子/m3。儿童卧室的室内/室外比值平均为可培养真菌的 4.2 和真菌孢子的 1.4。这些值高于前一年在同一家庭中测量的值：1.1 和 0.6。就特定真菌谱而言，事件发生后，室内和室外环境中的曲霉属 spp.的百分比均显着增加。到目前为止，这项研究是为数不多的定量证明即使采取了看似强有力的补救措施，洪水淹没的房屋中真菌仍可能持续存在的研究之一。仍然需要研究检查更好的补救技术的潜在健康影响和有效性。
