Final answer:
PPE adequacy can be compromised by inaction of authorities, equipment shortages, and inadequate infrastructure like water, sanitation, and hygiene practices.
Step-by-step explanation:
Three factors that prevent PPE adequacy are often tied to inaction, shortages of equipment, and underlying determinants such as inadequate infrastructure. Specifically:
- Inaction by authorities can lead to a delay in response to emerging threats, resulting in a lack of preparedness and insufficient stockpiles of necessary personal protective equipment (PPE).
- Equipment shortages occur when the supply chain is disrupted or unable to meet the sudden surge in demand, as seen during the initial phase of the pandemic in 2020.
- Underlying determinants, including inadequate water, sanitation, and solid waste disposal, along with improper hygiene practices, can undermine the effectiveness of PPE and contribute to its insufficiency.
