Scarves and bandana material were less effective, but still captured a fraction of particles. Face masks are necessary to guard others from novel coronavirus. There appears to be some benefit, but the precise parameters of which masks are the simplest and therefore the extent to which they protect the wearer or those around them are still being found out . A tighter fitting round the face is perhaps better, but the US Centers for Disease Control and Prevention (CDC) suggests any covering, including a bandana, is best than none.

Face masks are an easy thanks to help decrease coronavirus transmission and save lives. consistent with the Centers for Disease Control and Prevention, wearing a mask publicly places has been shown to scale back the spread of COVID-19, because those that are pre-symptomatic can spread the virus before showing symptoms. However, some masks are simpler than others.
