Study Overview

A striking new study has revealed that the reporting of human adenoviruses (HAdVs) has dramatically declined since the onset of the COVID-19 pandemic. This alarming trend was documented in research published in the December 19 issue of the CDC's Morbidity and Mortality Weekly Report.

Research Conducted by CDC

Led by Fatima Abdirizak, M.P.H., from the Centers for Disease Control and Prevention in Atlanta, the study examined the distribution of HAdV types reported to the National Adenovirus Type Reporting System over the span from 2017 to 2023.

Findings from the Study

According to the findings, a total of 2,241 HAdV specimens with typing results were reported during the seven-year period. From 2017 to 2019, reports of these specimens fluctuated significantly, ranging from 389 to 562 annually. However, a concerning drop occurred between 2020 and 2023, with reports plummeting to between 58 and 356 specimens per year. Alarmingly, six HAdV types (specifically types 1, 2, 4, 7, and 14) comprised a staggering 88.3% of the typed specimens accounted during this period, with a significant 17% connected to outbreaks.

Interesting Spike in Reporting

Interestingly, the period from 2021 to 2022 saw a peculiar spike in reporting for type 41, coinciding with a hepatitis cluster, raising questions about possible links between these health issues. Despite the continued circulation of HAdVs that was observed through passive laboratory surveillance, the National Adenovirus Type Reporting System has nonetheless experienced a noticeable decline in submissions.

Call for Improved Reporting

The researchers emphasized, “Enhanced reporting and greater laboratory capacity to type HAdVs can significantly improve our national understanding of their circulation patterns." Such improvements are vital for properly informing public health strategies and prevention measures aimed at controlling outbreaks.

Public Health Implications

As we emerge from the shadow of the pandemic, this research underscores the critical importance of monitoring viruses like HAdVs to ensure public health safety. Are we overlooking a hidden health crisis with these dwindling reports? We must keep our eyes open and demand better data to protect our communities! Stay informed and vigilant!
