In addition to your comprehensive fact-check, I might add this could be further enhanced by discussing the importance of proper mask usage and fit. The effectiveness of masks is significantly influenced by how well they fit and are worn. The Harvard Health article notes that "surgical masks are helpful, but less protective, partly because they do not fit snugly." Ensuring a snug fit over the nose and mouth without gaps is crucial for maximizing protection. Moreover, combining mask usage with other preventive measures, such as vaccination, hand hygiene, and physical distancing, offers a more comprehensive approach to reducing virus spread.
