The provisional pilot study shows, the hood offers several potential implications. In terms of healthcare workers' safety, the hood ensures lower close contact with the patients, primarily perform medical and surgical procedures that can potentially generate aerosolized particles include intubation and bronchoscopy. It has been observed that efficient containment can be achieved using simple construction and essential medical equipment by considering pressure differential and airflow patterns. This experiment has several limitations. Due to clinical restrictions during an outbreak, the simulations only presumed the patient lying on bed without any movement around the room. Thus, we are unable to control under any humanenvironment condition, and the air ventilation in the room would have thinned the presence of fluorescent markers on the surfaces. Moreover, the environmental sites sampled represent only a small fraction of the total area. Further studies are required to validate these initial results. The hood protects patients that would be required to undergo several tests differently, radiology, physical therapy, pulmonary, and laboratory. Even in situations where a patient needs to be moved to another facility, the hood could limit the exposure to other patients and hospital personnel. We urged that with the protection provided to both patient and hospital personnel, visitors of the health facility are protected from possible exposure. This result is consistent with other researchers 4-5 that emphasize the need to adapt to the healthcare setting in the wake of the COVID-19 pandemic.
