Unpacking the Controversy: The Weakening of Infection Prevention Guidelines Amid a Potential Respiratory Outbreak

Children attending a hospital in Beijing in November 2023 have prompted the World Health Organization (WHO) to call for more data on a respiratory illness currently proliferating in China. This seemingly ‘influenza-like’ illness has experienced an increased rate since mid-October – a significant anomaly when compared to previous years’ data. An early warning of a possible extensive outbreak of respiratory infections and pneumonia clusters in children was issued by ProMed-mail, an early warning network from the International Society for Infectious Diseases. The WHO further escalated the alert on a global scale on the 22nd of November.

Following a unanimous vote on November 3 by the Healthcare Infection Control Advisory Committee (HICPAC), a draft of guidelines has been accepted. These new guidelines – met with widespread criticism – are expected to weaken infection prevention precautions. They now await the approval of Mandy Cohen, the CDC director. Critics of the guidelines argue that they dilute protective measures against infection in favor of cost-saving options. A controversial recommendation includes the adoption of surgical masks as a new standard, asserting their comparability to N95 masks’ protectiveness.

Peg Seminario, a retired safety, and health director for the AFL-CIO, is one such critic who believes the proposed guidelines do not adequately protect healthcare workers and patients. In support of this, Seminario refers to a recent report showing an increase of 37.5% in respiratory illnesses in the private health care sector from 2021 to 2022. Despite this, HICPAC continues to recommend reducing protections.

Another source of criticism stems from the condemnation of the Cochrane Review, a systematic literature review that concluded the minimal differences between surgical mask and N95 mask efficacy. High-quality evidence, however, counters this, according to aerosol researcher Jose-Luis Jimenez, suggesting N95 masks to be superior. Furthermore, HICPAC’s recommendations are criticized for ignoring ample evidence of the airborne transmission of most respiratory viruses and failing to address virus removal measures from room air.

Allegations of secrecy overshadow HICPAC and the CDC’s procedures, with experts arguing that the inability of NIOSH experts to engage with the press reveals the potential contradictions between science and CDC policies. Moreover, HICPAC has been criticized for its failure to release details of committee meetings or open up documents for review, alongside restricting public comment.

The HICPAC committee’s membership has been flagged as too narrow, with claims it fails to represent the necessary range of expertise. The World Health Network raised these concerns with the Office of the Inspector General, arguing that the HICPAC is detrimentally constituted and fails to maintain a balanced variety of viewpoints and functions.

While the current draft recommendations have been sent to the CDC for approval, there is little hope for any adjustments reflecting public input. Given the increasing rate of infection, emphasizing hospital care, these proceedings are of substantial interest to healthcare professionals. The CDC’s upcoming response to HICPAC’s controversial recommendations are eagerly awaited.
