What is the primary preventive measure against bronchiolitis?

The primary preventive measure against bronchiolitis is the promotion of hand hygiene and the avoidance of sick individuals. Bronchiolitis, often caused by respiratory syncytial virus (RSV), primarily spreads through respiratory droplets and contact with contaminated surfaces. By incorporating effective hand hygiene practices, such as regular handwashing with soap and water or using alcohol-based hand sanitizers, the likelihood of transmission can be significantly reduced. Additionally, keeping distance from individuals who exhibit respiratory infections helps minimize exposure to pathogens that can lead to bronchiolitis.

Although immunization against RSV is an important consideration, especially for high-risk infants, it is not universally recommended for all infants as a routine preventive measure. The use of antiviral medications is generally not applicable to bronchiolitis management and is more suited to other viral infections. Regular physical activity, while beneficial for overall health, does not specifically prevent bronchiolitis and is not targeted at controlling the spread of respiratory viruses. Thus, promoting hand hygiene and avoiding close contact with infected individuals remain the most vital strategies in preventing bronchiolitis.
