Solar disinfection (SODIS) could be a key to providing a clean, hygiene water for birthing uses, but the recommended climate zone is limited, the microbial indicators are related to gastrointestinal illness and not wound infections. SODIS feasibility was investigated to remove Escherichia coli from turbid water at temperatures less than 50 °C in Lexington, KY. Increasing turbidity from 0 to 200 NTU decreased E. coli inactivation from 5 to 1 log. With the same experimental protocol, more than 4-log inactivation of Staphylococcus aureus and Staphylococcus epidermidis (common human-skin microorganisms related to serious post-partum infections of both mother and child) was achieved at different turbidity levels with a maximum, in-bottle temperature of 49.2 °C after 5.5 h. The thermal inactivation of the bacterial indicators was assessed without UV radiation and turbidity in water at 37 and 47 °C. Skin bacteria were inactivated completely after 9.5 h at 47 °C, but only 58% removal happened for thermo-tolerant E. coli. These results suggest that SODIS application may be expanded geographically to treat water for hygiene purposes. However, as E. coli is also capable of causing wound infections, UV with thermal inactivation may be required to produce safe hygiene water by SODIS outside of recommended latitudes.

太阳能消毒 (SODIS) 可能是为分娩提供清洁卫生用水的关键，但推荐的气候区有限，微生物指标与胃肠道疾病有关，与伤口感染无关。在肯塔基州列克星敦，研究了 SODIS在低于 50 °C 的温度下从浑浊水中去除大肠杆菌的可行性。将浊度从 0 增加到 200 NTU 将大肠杆菌灭活从 5 log降低到 1 log。使用相同的实验方案，金黄色葡萄球菌和表皮葡萄球菌的灭活超过 4-log（与母婴严重产后感染相关的常见人类皮肤微生物）在不同浊度水平下达到，5.5 小时后瓶内温度最高为 49.2 °C。在 37 和 47 °C 下，在没有紫外线辐射和水中浊度的情况下评估细菌指示剂的热灭活。皮肤细菌在 47°C 下 9.5 小时后完全灭活，但耐热大肠杆菌仅发生 58% 的去除。这些结果表明 SODIS 的应用可能会在地理上扩展到出于卫生目的处理水。然而，由于大肠杆菌也能引起伤口感染，因此 SODIS 在推荐纬度之外可能需要具有热灭活功能的紫外线来生产安全的卫生用水。
