Face Masks can Save You from Respiratory Infections

Surgical face masks can protect you from common respiratory symptoms like runny nose, sore throat, coughing and sneezing. So, properly wear a face mask for infection protection.

Wearing a surgical face mask in public spaces is one of the easiest and most cost-effective preventive measures to reduce the spread of respiratory infections, finds a new study. The findings of the study are published in The BMJ ().

Respiratory Diseases
Respiratory diseases affect any part of the respiratory system. Some of the lung diseases like chronic obstructive pulmonary disease can lead to respiratory failure.

Do Surgical Masks Protect against Respiratory Tract Infections (RTIs)?

The effect was moderate - a 3.2% reduction in symptoms, equivalent to around 3,300 fewer infections per 100,000 people - but the researchers say these results support the claim that face masks may be an effective measure to reduce the rate of self-reported symptoms consistent with respiratory tract infections.

Observational studies suggest that face masks reduce the risk of respiratory tract infections (RTIs), but findings from randomized trials are inconclusive.

To explore this further, the researchers carried out a randomized controlled trial to evaluate the personal protective effects of wearing versus not wearing surgical face masks in public spaces on self-reported respiratory symptoms over a 14 day period.

Their findings are based on data from 4,575 adults in Norway (average age 51; 61% women) between 10 February 2023 and 27 April 2023, during a normal influenza season in the Nordic countries.

Participants completed an online questionnaire about sociodemographic and lifestyle factors, beliefs about face masks and risk of infection, and face mask use in the two weeks before the study.

Some 2,313 participants were then randomly assigned to wear a disposable surgical face mask when close to people in public spaces (eg, shopping centres, streets, public transport) over 14 days (intervention arm) and 2,262 were asked to remain mask-free when close to people in public spaces (control arm).

Participants were asked to report any symptoms consistent with a respiratory infection, defined as fever and one respiratory symptom (stuffy or runny nose, sore throat, coughing, sneezing, heavy breathing); or one respiratory symptom and at least two other symptoms (body ache, muscular pain, fatigue, reduced appetite, stomach pain, headache, loss of smell).

They were also encouraged to take a COVID-19 test when they felt unwell, but the number of participants taking a test was low.

Overall, 163 (8.9%) participants in the intervention arm and 239 (12.2%) in the control arm reported respiratory symptoms - an absolute risk difference of 3.2% in favor of the face mask intervention. However, no statistically significant effect was found on self-reported or registered covid-19 infection between the two arms.

Does Your Face Mask Fit Your Face Shape?
Double masking with improperly fitted masks does not protect you from Covid-19 infection. Therefore, your mask needs to fit your face shape.

Common Reasons for Not Wearing a Mask

Of 155 participants who reported adverse effects, 80 reported unpleasant comments from other people when wearing a face mask in public spaces and feeling “silly” being the only one wearing a face mask in public. Others (40) said wearing the mask was uncomfortable or tiring because of breathing difficulties, fogging of glasses, and poor fit.

The authors acknowledge that all the data were self-reported and suggest that wearing a face mask may have led participants to avoid public spaces or others to keep a larger social distance.

Environmental concerns associated with face masks (eg, manufacture and transport, emissions, littering, landfill) should also be considered, they add.

A facemask is generally used to cover the face to prevent the spread of infection, to disguise or for protection against disease or pollution. Facemasks are also used for ceremonial and ritualistic practices. The term acne, pimples and dryness of ...

Masks Save Lives

Nevertheless, they conclude that wearing a face mask is a simple, relatively low cost, and generally well tolerated intervention and is one of several public health and social measures that may be worth considering for reducing the spread of respiratory infections.
