MASK PROTECTION: CLOTH VS PLASTIC SHIELDS FOR INFECTION PREVENTION
With the ongoing coronavirus pandemic, the choice between a cloth mask and a plastic shield can be a confusing one. Both offer varying degrees of protection, but which one provides better protection against infection? We explore the differences and considerations for choosing the right protective equipment.
The Efficacy of Masks and Shields
While plastic shields offer better protection, they can be inconvenient to wear for extended periods. In an outbreak in Switzerland, face shields were not found to effectively protect people from coronavirus, whereas masks did. However, masks and shields are generally considered equally inefficient in terms of protecting the user.
The primary purpose of masks is not to protect the wearer but to slow down the rate of transmission from the wearer. This is especially important for those who are asymptomatic and can unknowingly spread the virus.
Medical Professional Recommendations
The Centers for Disease Control and Prevention (CDC) continues to recommend the use of "cloth face coverings" in public settings where other social distancing measures are challenging to maintain. Some health experts argue, however, that shields might be even more effective for daily activities outside of high-risk healthcare settings. For medical professionals dealing with potentially infected patients, both a shield and a mask are recommended for optimal protection.
Comfort and Efficiency
Comfort and ease of use are crucial factors when choosing between a mask and a shield. Some people find it easier to breathe with a shield, which may make it more comfortable to wear for extended periods. From a health standpoint, neither the shield nor the mask is inherently better; it depends on the situation and the user's preferences.
Health care providers are increasingly using a combination of a surgical mask and a plastic shield. The plastic shield, being easy to clean and disinfect, provides an additional layer of protection. A homemade mask made from T-shirt material should be at least three layers and tightly fitting for maximum effectiveness, with cotton being the preferred material.
Studies have compared various mask materials, but for the general public, comfort is a more critical factor. The best mask is one that you can wear comfortably and consistently, as advised by medical professionals at the University of California, San Francisco (UCSF).
Conclusion
While plastic shields offer better protection, they may not be practical for all situations due to comfort and convenience. Cloth masks, on the other hand, provide an effective layer of protection and are widely accessible. Ultimately, the choice between a mask and a shield should consider your individual needs and the activities you plan to engage in.
