Flu from China, 2026
Things we can learn from the video
Press to jump
- 4:12Campbell reviews Chinese reports of seasonal flu outbreaks and human H9N2 bird flu cases.
- 5:55He cites the European assessment that risk to Europe's general population is very low.
- 8:00He identifies the seasonal pattern as antigenic drift, rather than a novel antigenic shift.
- 9:25Hong Kong's school outbreaks and hospital complications show the serious consequences seasonal flu can have.
- 16:57A diagram explains how reassortment involving influenza viruses from different hosts can generate new strains.
- 22:48Answering the pandemic question, Campbell says the surveillance he has reviewed does not indicate one is imminent.
Reports of closed schools and children needing hospital care in China prompted requests for John Campbell to take a closer look. His answer draws an important distinction: a serious seasonal flu outbreak is not the same thing as a new pandemic virus.
"Flu from China, 2026" reached about 218,000 views in nine hours, already more than four times the channel's usual full-day audience for a regular video.
Campbell, a retired nurse teacher whose doctorate focused on learning resources for nurses, works through reports from Chinese, European, British and American health agencies. He notes that, despite his caution towards official sources, their reporting largely aligns.
Reviewing the Chinese reports, he describes increasing flu activity and school outbreaks. He also covers hospital admissions and complications in Hong Kong. But he emphasises that the seasonal viruses under discussion are established strains already circulating internationally. He cites the European Centre for Disease Prevention and Control's assessment of very low risk to Europe's general population.
The central teaching point is the difference between antigenic drift, the changes influenza undergoes from season to season, and reassortment, which can produce substantially different viruses. A diagram involving pigs, poultry and humans explains the latter; Campbell says the present seasonal pattern is drift.
His direct answer to the pandemic question comes near the end: "Are we expecting a major pandemic? On current data from three government agencies, four government agencies around the world, the answer is no."
