H5N1 bird flu detected in vampire bats feeding on coastal wildlife of Peru

Scientists have detected H5N1 bird flu exposure in vampire bats, revealing a previously hidden wildlife pathway that could influence how dangerous viruses move between species.

Scientists have detected signs of H5N1 bird flu exposure in bats. The discovery involves vampire bats living along Peru’s coastal regions. The finding raises concerns about new mammal hosts for dangerous viruses. H5N1 has already devastated birds and marine mammals across South America.

Coastal Feeding Linked to Exposure

Researchers sampled hundreds of vampire bats from multiple Peruvian locations. Only bats from coastal regions showed antibodies against the H5N1 virus. These bats feed on marine animals, including seabirds and sea lions. Inland bats showed no evidence of bird flu exposure.

Laboratory Tests Confirm Viral Binding

Scientists tested whether H5N1 could infect bat tissues in laboratories. The virus successfully attached to lung and liver cells from bats. Experiments confirmed the virus can infect bat cells under controlled conditions. This suggests bats could theoretically support viral replication.

Limited Evidence Of Bat Transmission

Despite exposure, scientists found no strong evidence of bat-to-bat transmission. The virus appears poorly adapted for sustained spread among bats currently. Researchers stress that spillover does not equal ongoing circulation. Continuous monitoring remains essential as viral evolution can change rapidly.

Why This Discovery Matters?

H5N1 continues spreading across new species, increasing pandemic risks globally. Understanding animal hosts helps scientists predict and prevent future outbreaks. Bats often host viruses without severe illness, complicating detection efforts. This study highlights hidden transmission pathways between wildlife species.

Next Steps For Global Surveillance

Scientists urge expanded wildlife surveillance across affected regions. Future studies will examine whether bats can transmit H5N1 onward. Monitoring viral mutations will assess risks of mammalian adaptation. Early detection remains critical for protecting human and animal health worldwide.
