Harnessing Safety First: Revisiting Pandemic Guidelines In The Wake of Covid-19

Reflecting back on the early days of the COVID-19 surge in New York City in 2020, emergency physician Sonya Stokes recalls the healthcare system’s unpreparedness and misguided strategies, which had serious repercussions on both healthcare workers and patients alike. The directives from hospital leaders to abstain from using protective N95 masks, despite rapidly increasing COVID-19 case counts, raised grave concerns for front-line workers who were placed in the path of the virus with inadequate protection. The toll was heavy, with more than 3,600 healthcare workers losing their lives in the first year itself, and many others left dealing with consequential health impacts or transmitting the virus to their families.

To justify not using N95 masks, hospital leadership, across various regions, relied on the advice from The Centers for Disease Control and Prevention (CDC) which suggested that airborne transmission was limited and that N95 respirators were only essential for specific medical procedures performed at extremely close distances. This stance was in discordance with the findings from scientists specializing in airborne viral transmission research, and with the realities witnessed by doctors on the frontlines.

Hospitals, nursing homes, prisons and other health care facilities are anxiously anticipating the CDC’s updated guidelines on controlling the spread of infectious diseases – a set of standards that will serve as the foundation for future practices and protocols. Late last year, the preliminary draft of these guidelines was evaluated and faced criticism from unions, aerosol scientists, and workplace safety experts, who voiced concerns that the draft permitted employers to make potentially dangerous decisions regarding the protection against airborne infections. In an uncommon move, the CDC has revisited the draft guidelines to better address the complexities of airborne transmission.

The contentious aspect of the drafted guidelines is the delineation of different methods for airborne viruses that ‘spread predominantly over short distances’ versus those that ‘spread efficiently over long distances’. This has been a point of dispute amongst researchers, with experts like Don Milton, a leading aerobiology researcher, stressing the importance of understanding the routes of infection, the concentration of virus-laden droplets, and the risk factors associated with exposure to these airborne particles.

The impending guidelines carry significant weight, as they will dictate future health care practices. Critics worry that if the document does not explicitly state the need for measures such as N95 masks use, health facilities may not adequately stockpile for future outbreaks, potentially leading to the recurrence of the crippling shortages experienced during the COVID-19 pandemic. Adequate emphasis on ventilation and air filtration is also deemed important, acting as key to prevent airborne disease spread. Dr. Stokes, expressing the concern of many healthcare professionals, states ‘If the CDC doesn’t prioritize the safety of health providers, health systems will err on the side of doing less, especially in an economic downturn. The people in charge of these decisions should be the ones forced to take those risks.’
