Recent research conducted by Queensland Health challenges the notion that "long COVID" represents a distinct illness separate from other post-viral syndromes, such as those experienced after influenza.

1. Study Challenges Notion of “Long COVID” as
Distinct from Post-Viral Syndromes
Research Findings Question Unique Nature of Prolonged
COVID Symptoms
Recent research conducted by Queensland Health challenges the notion that “long COVID”
represents a distinct illness separate from other post-viral syndromes, such as those experienced
after influenza. Led by Dr. John Gerrard, the state’s chief health officer, the study suggests it’s
time to reconsider the use of terms like “long COVID,” as they may inaccurately imply a
uniqueness to the longer-term symptoms associated with the virus.
Similarity in Symptoms and Impairment
Participants in the study, surveyed a year after their COVID-19 diagnosis, reported ongoing
symptoms and impairment levels. Surprisingly, the study found no significant difference in
functional limitations between those who had COVID-19 and those who did not. The incidence of
ongoing impairments after COVID-19 infection mirrored those observed in individuals
recovering from influenza, challenging the notion of long COVID as a distinct and severe illness.
Implications for Public Health Discourse
Dr. Gerrard emphasized the potential harm caused by using terms like “long COVID,” suggesting
they could induce unnecessary fear and hypervigilance among patients. He emphasized the need
for a nuanced understanding of post-viral syndromes and cautioned against overstating the
uniqueness of symptoms attributed to COVID-19.

2. Response from Experts
While the study sheds light on the similarities between COVID-19 and other respiratory viruses,
some experts caution against dismissing the term “long COVID” entirely. Prof. Philip Britton
from the University of Sydney acknowledges the study’s value but warns against overstating its
conclusions. Similarly, Prof. Jeremy Nicholson from Murdoch University highlights the need for
further physiological assessment to determine the distinctiveness of long COVID.
As the discourse surrounding post-viral syndromes continues to evolve, this study prompts a
reevaluation of terminology and underscores the importance of evidence-based approaches in
understanding the long-term effects of COVID-19.
