## Face Mask Use in the Community for Reducing the Spread of COVID-19: A Systematic Review

Types of markers utilized to control various respiratory viruses. Majority of the studies (n = 55) contained in the review reported the use of various types of face masks to manage the transmission of respiratory viruses.

Efficacy of face mask within local interventions could have an aggregate effect on the reproduction amount of the epidemic. In this section, we look at models who have attempted to estimate the possible magnitude of such a result. The basic reproduction number R0 is estimated to be the product range 2.4 to three.9 (36). All studies that compared the usage of face mask, irrespective of the sort, to non-use of breathing filter observed a substantially higher rate of infection one of many participants who failed to use mask. For instance, Wang et al. (2020a) reported no SARS-CoV-2 infection among participants who wore a breathing filter whilst 10 participants inside the no mask group were infected.

## Conclusion

We are also cognisant of all the so-called systematic reviews conducted about the utilization of goggles and other face-covering (MacIntyre and Chughtai, 2020, Bartoszko et al., 2020, Benkouiten and Brouqui, 2014, Bin-Reza et al., 2012, Chu et al., 2020, Jefferson et al., 2011, Liang et al., 2020, MacIntyre and Chungtai, 2015, MacIntyre et al., 2017, Offeddu et al., 2017, Saunders-Hastings et al., 2017, Smith et al., 2016, Xiao et al., 2020). These reviews have mainly focused on: (a) a mixture of different primary study designs (Bartoszko et al., 2020, Benkouiten and Brouqui, 2014, Bin-Reza et al., 2012, Chu et al., 2020, Jefferson et al., 2011, Liang et al., 2020, Offeddu et al., 2017, Saunders-Hastings et al., 2017, Smith et al., 2016); (b) only randomised controlled trials (MacIntyre and Chughtai, 2020, MacIntyre and Chungtai, 2015, MacIntyre et al., 2017, Xiao et al., 2020); (c) studied multiple interventions in addition to face-covering (Bin-Reza et al., 2012, Chu et al., 2020, Liang et al., 2020, Offeddu et al., 2017); (d) only healthcare workers and general population (Bin-Reza et al., 2012, Chu et al., 2020, Jefferson et al., 2011, Liang et al., 2020.
