Understanding infections related to handling healthcare waste products is of critical importance and the application of simple and low-cost strategies remain a priority in low-income and middle-income countries to protect healthcare workers. We examined the potential effect of relative humidity (RH), air temperature and ultraviolet irradiation (UI) to establish an efficient and effective way to facilitate disposal of medical waste. Literature is emerging on the effect of high RH and high temperature, which would increase airborne mass deposition and decrease the viability of viruses in both airborne particles and on surfaces. On the other hand, severe acute respiratory syndrome coronavirus-2 has been proven to be susceptible to UI when suspended in air like other coronaviruses. An innovative approach utilizing environmental conditions might represent an effective and efficient way to ensure better and sustainable protection of the healthcare workers in low-resourced settings.
了解与处理医疗废物相关的感染至关重要,在中低收入国家,应用简单且低成本的策略仍然是优先事项,以保护医护人员。我们研究了相对湿度(RH)、空气温度和紫外线照射(UI)的潜在影响,以确定一种有效且高效的方法来促进医疗废物的处理。关于高 RH 和高温的影响的文献正在不断涌现,这将增加空气中颗粒的质量沉积,并降低空气中的病毒颗粒和表面上病毒的存活能力。另一方面,严重急性呼吸综合征冠状病毒-2 已被证明像其他冠状病毒一样,在空气中悬浮时易受 UI 影响。利用环境条件的创新方法可能代表了一种有效且高效的方法,可以确保在资源匮乏的环境中更好和更可持续地保护医护人员。
