Are face masks useful for stopping the spread of COVID-19?

COVID-19 could well be a preventable disease, and this pandemic is facilitating an enormous rise of need for healthcare face masks from the basic pubic and health experts. In this post, science led consumer healthcare company Clinova, that has noticed an enormous rise in enquiries from the public regarding the face mask product of its, Covaflu, answers the most typical question about the suitability of face masks.

Clinova says the most typical issue is all about the suitability of various face mask types for minimising the danger of contracting COVID 19.
Can masks’ flatten the curve’?

With attempts to’ flatten the curve’ increasing all around the planet, there’s been controversy regarding the efficacy of using a face mask.

While remaining 2 meters apart when from the home of yours on trips that are important is imperative, as well as washing the hands of yours upon return, the advantages of a mask are physical.

If wearing a mask stops a top percent of putting in the respiratory system of yours, the advantage of theirs is obvious, says Clinova. While healthcare face masks don’t ensure hundred % safety for the wearer, they nevertheless substantially reduce the chance of disease, and also when trying to flatten the curve, any decrease in transmission rates is pleasant.
Face masks, respiratory masks or medical masks?

Regardless of the safety advice of staying 2 metres beyond others, sneezing and coughing can project virus particulates 6 meters away.

Sneezing and coughing create a “muzzle velocity” of fifty meters/second (for sneezing) or maybe ten m/s (for coughing), rendering the two meter protection zone of very little assistance without having an extra barrier in the kind of a mask.

Nevertheless, unlike medical masks or standard facemasks, breathing masks protect against aqueous as well as oily aerosols, smoke and fine particles in. The appropriate function of theirs is verified by the Europe wide EN 149 standard and split into FFP3 and FFP2, these standards verify protection from avian flu, SRAS, tuberculosis, in addition to infection respiratory pathogens, along with germs.

The 2 classifications moreover indicate the amount of particulates filtered out by the mask, the buy ffp2 mask filters ninety four % and FFP3 filters ninety nine %. The greater number of particles that have to be filtered, the higher the variety of filter material layers. So, masks in the increased protection classes are thicker, which means breathing resistance is higher.

Particle-filtering face masks protect against particles, however, not vapours or even gases.

Arsalan Karim, Director of Development and Research of Clinova, explains: “Right now, there is a great deal of discussion about various types of protective masks, and what you are right. While medical masks protect against infectious agents transmitted by droplets, they don’t guard against airborne infectious agents like viruses, therefore they won’t stop the wearer from remaining likely infected by COVID 19.

“However, the respirator face mask, which protects the wearer from aqueous as well as oily aerosols, smoke cigarettes, then facial dust, is more efficient at guarding against airborne infectious agents like COVID 19 and SARS. Respirator masks stop viruses from entering the body from the mucous membranes of the jaws and nostrils.”
