We have identified many factors that increase the risk of long COVID, but there are others I'm sure that will still be identified with continued research and monitoring.

The bottom line is we still have a lot of work to do to better understand this very issue.

A ‘hijacked plane’: CDC, under RFK Jr.’s influence, trades science for dogma A series of controversial policy changes directed by the HHS secretary have left experts fearful of the future implications for public health.

Since the ACIP has been reconstituted last year, nothing that has been put forward by them is based on science or evidence, not one single change. This is unlike the previous 50-year history.

Thank you to the organizers for the invitation.

His work did not just defeat a scourge; it redefined what is possible in public health and demonstrated the power of evidence-based strategy to build trust and save lives on a global scale. Bill’s legacy is vast and enduring, and his efforts did not stop with smallpox.

Under his guidance, a disease that once claimed millions of lives was brought to an end, not through brute force but through ingenuity, scientific rigor, community engagement and a profound commitment to protecting the world’s most vulnerable.

We are deeply saddened by the loss of Dr. William H. Foege, a towering figure in global public health whose visionary leadership changed the course of human history. Bill's contributions to the eradication of smallpox stand as one of the most extraordinary achievements in medicine and epidemiology.
