我关注H5N1禽流感病毒已25年，它能导致人类严重疾病并在禽类间传播。近年来，一种新的H5N1毒株在全球范围内迅速传播，已感染哺乳动物，尤其是在美国，它不仅感染了奶牛，还适应了在牛群中传播，并通过牛奶传播。这引发了人们对人类感染的担忧，因为人们可能通过接触受感染的奶牛或饮用未经巴氏消毒的牛奶而感染病毒。虽然目前没有证据表明人际传播，但我们仍需密切关注，并采取生物安全措施，例如在农场减少动物感染风险，以及在接触动物时佩戴适当的个人防护装备。此外，未经巴氏消毒的牛奶消费也令人担忧。值得庆幸的是，我们知道如何制造流感疫苗，并且已经生产了H5N1疫苗，即使疫苗并非完全匹配，也能降低严重症状或传播风险。

Chapters
The US reports its first human death from H5N1 bird flu, raising concerns about its spread among mammals. The virus is spreading rapidly in birds and has now infected dairy cows, raising concerns about transmission to humans through contact with infected cattle or consumption of unpasteurized milk. While human-to-human transmission is not yet evident, there are concerns about the virus's potential to mutate or combine with other viruses to become more efficient at infecting humans.
  • First human death from H5N1 bird flu reported in the US
  • Virus is spreading in cows and domestic/wild cats
  • Concerns about transmission to humans via contact with infected cattle or unpasteurized milk
  • No evidence of human-to-human transmission yet
  • Concerns about virus mutation or combination with other viruses

Shownotes Transcript

Dr Chris Smith and the Naked Scientist team present the latest science news, analysis and breakthroughs.

Including the news that the US has recorded their first human death from bird flu, and should we be concerned? Plus a new drug to treat drug resistant prostate cancer, and new research on how the Roman Empire was responsible for widespread lead pollution in Europe.

In Part 2, Titans of Science returns with Marc Abrahams, the originator of the Ig Nobel Prize and the master of making science funny.

This is the final episode of 5 Live Science in this feed, but you can still hear Dr Chris Smith regularly on BBC Radio 5 Live with Naga Munchetty on a Tuesday afternoon at 1pm. You can also search for “The Naked Scientists Podcast” online for more from Dr Chris and the team.
