What type of face mask should we choose in coronavirus disease 2019 pandemic considering photoprotective effectiveness?

ABSTRACT:

Background

Wearing a face mask is one of the most effective personal protective strategies to diminish the spread of coronavirus disease 2019 (COVID-19). Several dermatological outcomes were reported because of the prolonged use of face masks, especially due to the constant mask-on policy, but the photoprotective effect of face masks has received less attention.

Objective

The aim of this study was to provide guidance in the use of face masks by comparing the photoprotective effects of routinely used masks.

Methods

A total of 12 frequently used face masks were tested, including certified respirators, Korea filter (KF)94, KF-anti-droplet (KF-AD), and KF80. The amount of light that penetrates each face mask was measured using a light sensor that can quantify Ultraviolet A (UVA), visible light (VL), and infrared A (IR-A) rays.

Results

Black-colored KF94 masks and surgical masks reduced penetration of UVA, VL, and IR-A by approximately 100%. The UVA penetration decreased on average by 95.51%, 90.97%, 85.06%, and 86.41% with white-colored KF94, KF-AD, KF80, and surgical masks, respectively. The VL and IR-A were blocked by approximately 75.58%, 66.16%, 59.18%, and 64.48% with white-colored KF94, KF-AD, KF80, and surgical masks, respectively.

Conclusion

In conclusion, the different photoprotective effectiveness of face masks was mainly determined by colors, and therefore, black-colored, multi-layered respirators can be recommended in terms of photoprotection in the COVID-19 pandemic. The quantified comparative results will be helpful to the person with pre-existing photo-aggravated dermatosis, especially in the season of the high intensity of sunlight.

Project description:Background. Coronavirus disease (COVID-19) is a highly communicable virus that continues to interrupt livelihoods, predominantly those of low-income segments of society. For the prevention of respiratory infections like the current COVID-19 outbreak, face masks are considered an effective approach.Objective. This study intended to assess the knowledge, attitude, and practice of public transport drivers towards face mask use amid the COVID-19 pandemic in Gondar, Ethiopia.Methods. A cross-sectional study was conducted among 412 public transport drivers in Gondar town from July to September 2021. The study subjects were recruited using a simple random sampling technique after proportionally allocating the sample size from the total number of public transport drivers, and finally, study subjects were selected using the convenience sampling method to select the participant drivers working in Gondar Town. The data were collected by face-to-face interview administered questioners and an on-the-spot observational checklist.Results. A total of 412 public transport drivers have participated in the study. The mean age of the respondents was 32.75 years (±8.75 years). The majority of the participants were Bajaj drivers 193 (46.84%). Among the responders, 114 (27.67%) of them use radio to gather information about the pandemic and 50 (12.14%) of them had reported being caught by COVID-19. Meanwhile, only 32 (7.77%) were vaccinated against COVID-19. Drivers that had a diploma level of education were found to be 87.7% less knowledgeable than degree holders (AOR .123, 95% CI = .026, .573). Respondents that had good knowledge about COVID-19 and face masks were found to have 1.7 times more positive attitudes than those that had poor knowledge (AOR = 1.728, 95% CI = 1.150, 2.596). drivers whose family members have ever been caught by COVID-19 were found 2 times more likely to use face masks whenever they are working/driving (AOR = 2.173, 95% CI = 1.015, 4.652) than their counterparts.Conclusion. This study revealed a very low Knowledge, attitude, and practice of face mask use among public transport drivers in Gondar town. Periodic reinforcement and training programs are needed for all public transport drivers in each level for proper understanding and adherence to COVID-19 prevention protocols and the use of face masks.

Project description:BackgroundFace mask use has been associated with declines in COVID-19 incidence rates worldwide. A handful of studies have examined the factors associated with face mask use in North America during the COVID-19 pandemic; however, much less is known about the patterns of face mask use and the impact of mask mandates during this time. This information could have important policy implications, now and in the event of future pandemics.ObjectiveTo address existing knowledge gaps, we assessed face mask usage patterns among British Columbia COVID-19 Population Mixing Patterns (BC-Mix) survey respondents and evaluated the impact of the provincial mask mandate on these usage patterns.MethodsBetween September 2020 and July 2022, adult British Columbia residents completed the web-based BC-Mix survey, answering questions on the circumstances surrounding face mask use or lack thereof, movement patterns, and COVID-19-related beliefs. Trends in face mask use over time were assessed, and associated factors were evaluated using multivariable logistic regression. A stratified analysis was done to examine effect modification by the provincial mask mandate.ResultsOf the 44,301 respondents, 81.9% reported wearing face masks during the 23-month period. In-store and public transit mask mandates supported monthly face mask usage rates of approximately 80%, which was further bolstered up to 92% with the introduction of the provincial mask mandate. Face mask users mostly visited retail locations (51.8%) and travelled alone by car (49.6%), whereas nonusers mostly traveled by car with others (35.2%) to their destinations-most commonly parks (45.7%). Nonusers of face masks were much more likely to be male than female, especially in retail locations and restaurants, bars, and cafés. In a multivariable logistic regression model adjusted for possible confounders, factors associated with face mask use included age, ethnicity, health region, mode of travel, destination, and time period. The odds of face mask use were 3.68 times greater when the provincial mask mandate was in effect than when it was not (adjusted odds ratio [aOR] 3.68, 95% CI 3.33-4.05). The impact of the mask mandate was greatest in restaurants, bars, or cafés (mandate: aOR 7.35, 95% CI 4.23-12.78 vs no mandate: aOR 2.81, 95% CI 1.50-5.26) and in retail locations (mandate: aOR 19.94, 95% CI 14.86-26.77 vs no mandate: aOR 7.71, 95% CI 5.68-10.46).ConclusionsStudy findings provide added insight into the dynamics of face mask use during the COVID-19 pandemic. Mask mandates supported increased and sustained high face mask usage rates during the first 2 years of the pandemic, having the greatest impact in indoor public locations with limited opportunity for physical distancing targeted by these mandates. These findings highlight the utility of mask mandates in supporting high face mask usage rates during the COVID-19 pandemic.
