Discovery of World’s Oldest Cold Virus : Scientists have pulled off something straight out of a sci-fi novel—they’ve revived the genetic blueprint of a common cold virus from a woman who lived over 250 years ago.

This isn’t just any old germ; it’s the oldest confirmed human RNA virus ever sequenced, hiding in preserved lung tissue from 1770s London.

Chasing Shadows in Ancient Tissue

Picture this: back in the day, doctors preserved body parts in jars of alcohol, no fancy chemicals involved. A team led by Erin Barnett at the Fred Hutchinson Cancer Center in Seattle dug through dusty pathology collections, zeroing in on the Hunterian Anatomy Museum at the University of Glasgow.

They struck gold with lung samples from two folks—one a mystery person from 1877, the other a London woman from around the 1770s who’d clearly battled brutal breathing problems.

RNA, the slippery stuff that makes up cold viruses like rhinoviruses, usually crumbles fast after death, gone in hours.

Unlike sturdier DNA, which we’ve yanked from 50,000-year-old bones, RNA’s fragility had kept ancient versions out of reach. But these alcohol-soaked lungs? They held fragments—tiny 20-to-30 nucleotide bits—that the researchers painstakingly pieced together like a mad scientist’s puzzle.

Piecing Together the Viral Ghost

It took grit and high-tech wizardry to rebuild that full rhinovirus genome from the 18th-century woman’s lungs.

Alongside it, they spotted bacterial culprits too: Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis, all notorious for gunking up lungs.

This poor soul wasn’t just sniffling; she was fighting a full-on respiratory war. They fed the sequence into the massive US National Institutes of Health database, packed with millions of modern viral genomes from every corner of the globe.

Boom—the ancient bug slotted into the human rhinovirus A group, but as an extinct branch hugging close to today’s A19 strain.

Crunching the evolutionary math, Barnett’s crew pegs their last common ancestor to the 1600s, showing how these sneeze-spreaders have shape-shifted over centuries.

Why This Hits Different Than DNA Wins

We’ve nailed ancient DNA viruses before, but RNA? That’s the holy grail because colds, flus, and worse like COVID come from RNA beasts that mutate like crazy.

No more relying on frozen mammoths or desert seeds for scraps—these “wet collections” from pre-1900s open a treasure trove.

Love Dalén from Stockholm University calls it the spark for an “explosion” in RNA virus studies, tracking how fast-mutating pathogens evolve across human history.

Think bigger: this could rewrite how we predict flu seasons or spot emerging threats. Those fragmented RNAs, averaging way shorter than living cells’ thousands-long strands, prove preservation tricks can beat the odds.

Suddenly, museum jars aren’t relics—they’re time capsules loaded with lessons on why we still reach for tissues every winter.

Echoes from the 18th Century

Who was this London woman? Her story’s mostly lost, just notes on her ravaged lungs. The team hopes spotlighting her DNA fingerprint honors the forgotten, turning anonymous specimens into named chapters in medical history. The 1877 sample yielded less, but even partial hits on bacteria hint at similar battles.

This find flips the script on ancient pathogen hunts. While woolly rhinos and Neanderthal bugs grab headlines, nailing a everyday cold virus genome pushes practical science forward. No drama of plagues, just the quiet grind of evolution in our noses.

Discovery of World’s Oldest Cold Virus The Road Ahead for Virus Hunters

Expect a rush to raid more archives. Dalén predicts centuries-spanning timelines will reveal mutation hot spots, maybe even why some rhinovirus strains dodge vaccines. Barnett’s group eyes older samples, betting alcohol jars hold more RNA gold.

In a world still reeling from pandemics, this arms us better. Understanding cold viruses’ deep roots could sharpen tools against their nastier RNA cousins. It’s not resurrection—it’s revelation, straight from history’s lungs.

Frequently Asked Questions

Q: How did they preserve the virus for 250 years? A: The lungs were stored in alcohol at the museum, shielding fragile RNA from total breakdown—unlike DNA, which lasts longer naturally.

Q: Is this virus dangerous today? A: No, it’s extinct and just genetic data; no live revival. Modern labs handle worse safely.

Q: What’s next for this research? A: Scouring more old collections for RNA timelines to track virus evolution and predict mutations.

Q: Why focus on common colds over deadlier viruses? A: RNA colds mutate fast; tracing them unlocks secrets for flus and beyond.

Q: Where was the sample from? A: Hunterian Anatomy Museum, University of Glasgow—lungs from a 1770s London woman.
