The pandemic potential

Between the lines: Influenza is of particular concern for health officials, even though there are more contagious viruses — for example, measles — and more deadly ones, like Ebola.
- But the flu virus can mutate quickly, sometimes acquiring a new ability to infect humans easily, causing concern about its potential to spark a pandemic, which happens when a new strain appears that most have no immunity against.
"The combination of a new deadly strain of flu plus air travel plus the ease with which it can be transmitted to other people. That really is the worst case scenario."— Lisa Monaco, former White House homeland security adviser, on "Axios on HBO"
One challenge with the flu virus is a virulent strain can emerge quickly and seemingly disappear rapidly, making it difficult to anticipate the virus' course and to develop a vaccine against its possible strains.
- Funding is being directed into the development of a universal flu vaccine that aims to offer broader immunity against different strains of the virus, but researchers face many obstacles. The National Institutes of Health is testing a vaccine and expects early results next year.
- Gates and others argue the world needs a multilateral pandemic response program — including a universal vaccine — to mitigate the threat of pandemic flu (and other pathogens).
"We are fooling ourselves if we think that we can do this alone, that it's only about what happens within the borders of our country. It has to be a global health security effort."— Lisa Monaco
Our thought bubble, per Axios' Eileen Drage O'Reilly: Emerging virulent pathogens are a threat each nation needs to report on a transparent basis to promote possible global coordination to halt their spread.
