Nebulizers (wet or jet) are one of the commonly used aerosol-generating medical devices and generate small particles that can spread to a larger distance than a normal breath. 1 The particles can also stimulate the patient's or any by-stander's cough mechanisms, which increase the risk of disease spread. This risk is linked not only to patients in medical facilities (offices, emergency departments, etc) who proved infected but to any patient with respiratory symptoms regardless of their infectious status. In conclusion, given that MDI/VHC has been shown to be as effective in numerous clinical situations, switching from nebulization to MDI/VHC treatment should be another important step that pediatricians can take in reducing COVID-19 spread, particularly among health caregivers.
