The Role of N95 Masks in Preventing the Transmission of Coronavirus

Since the beginning of the historic COVID-19 pandemic, one of the most debated topics has been protective respirator masks and whether they help slow the spread of the disease.

At the pandemic’s start, there was little evidence to prove or disprove the effectiveness of wearing protective respirators in slowing the spread of this particular coronavirus because COVID-19 was a new disease. Furthermore, little research focused on the transmission of respiratory diseases during a global pandemic of the magnitude of COVID-19, once-in-a-lifetime global disaster. Naturally, there was little data on the efficacy of the best respirator mask use during these exact circumstances.

Researchers in one study urge people not to infer from reading studies: 

Several authors have justified not wearing protective respirators masks for four main reasons. First, they claim that there is limited evidence that they are effective. The first argument can be questioned on the basis that the absence of evidence is not evidence of absence.

In the context of the COVID-19 pandemic, in health professionals who are in direct contact with people with suspected or diagnosed COVID-19, the Ministry of Health SUGGESTS the use of the best respirator N95 mask.

Some of the best respirator masks are designed to offer significant benefits in preventing the transmission of influenza viruses or other respiratory viruses. However, its cost is considerably higher. N95 masks may not be available in health centers in a prolonged pandemic, so it is advisable to rationalize their use.

The protective respirators mask is additionally beneficial for personnel who perform medical procedures such as tracheostomy, manual ventilation with an auto inflation bag or non-invasive mechanical ventilation.

The protective respirators may be more useful when the risk of transmission is lower, such as in the usual care of people with respiratory symptoms or without aerosol-generating procedures.

The group of specialists consulted considered the research evidence presented and their clinical experience and issued their judgment on the question, with which the recommendation was subsequently elaborated.
