Fruit fly study: enteric RNA viruses linked to accelerated biological aging
In Drosophila, transcriptomic aging clocks showed that all pathogenic enteric RNA virus infections accelerated biological aging, with the size of acceleration tracking pathogenicity; the pattern held across oral and systemic routes and was conserved in C. elegans. [1]

Aging clocks in virus-infected fruit flies
The study asked whether viral infections accelerate aging and whether the acceleration scales with pathogenicity, defined as reduction of host lifespan. Using transcriptomic aging clocks, the researchers measured biological age in Drosophila melanogaster infected with four enteric RNA viruses spanning a broad pathogenicity range.

Acceleration tracked pathogenicity across routes
All pathogenic infections accelerated aging, and the magnitude of acceleration tracked pathogenicity. This pattern held across oral and systemic infection routes and was conserved in Caenorhabditis elegans, where the nonpathogenic Orsay virus produced negligible aging acceleration. Pathway analysis indicated a systemic impact across aging hallmarks with virus- and tissue-specific signatures. Acceleration was comparable in females and males, but host context modulated it: the bacterial symbiont Wolbachia mitigated the virus-induced aging.

Elevated biological age after viral clearance
Notably, biological age remained elevated even after viral clearance. The authors interpret these results as viruses acting as age-distorters and link infection severity to lasting aging consequences, offering a quantitative framework for predicting long-term health effects of viral disease. These are findings in flies and worms using transcriptomic clocks; they do not establish human lifespan effects.

How to interpret this
Abstract only; the full text was not reviewed. Findings come from Drosophila and C. elegans using transcriptomic aging clocks, not from human studies, and do not establish human lifespan effects.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
