Given that the global supply of personal protective equipment (PPE) is insufficient during the pandemic, the World Health Organization recommends minimizing the need for PPE through telemedicine, physical barriers such as clear windows, allowing only those involved in direct care to enter a room with a COVID-19 patient, using only the PPE necessary for the specific task, continuing use of the same respirator without removing it while caring for multiple patients with the same diagnosis, monitoring and coordinating the PPE supply chain, and discouraging the use of masks for asymptomatic individuals.[25]
