HIV transmission during acute and early infection impedes efforts to end the epidemic.

To guide diagnosis and prevention strategies, we evaluated the geospatial and phylogenetic clustering of acute and recent HIV infections in Lilongwe, Malawi.

N.I.H. Workers Denounce Trump’s ‘Harmful’ Health Policies

One of the greatest tragedies of the gutting of the federal government is the loss of dedicated scientists who chose to work in public service for the benefit of the American people.

This letter is both incredibly brave and a testament to their integrity.

A 90 day pause in #PEPFAR will to lead to ~100,000 #HIV related deaths in one year. This is not considering any extension of the pause or future disruptions which we know is likely. For reference, this is DOUBLE as many people that have died in #Gaza.

What's happening with the anti-HIV program PEPFAR? It depends whom you ask The President's Emergency Plan for AIDS Relief has been the subject of a series of presidential orders and memos that have left uncertainty about how it operates.

Stopping #PEPFAR is anything but America 1st and here’s why (from a US perspective). Over the last 20 years working in Africa, I’ve watched China make massive gains here while PEPFAR has saved millions of lives and kept America influential. Cutting it now is a grave mistake.

We offer several risk score algorithms based on the level of data availability, for both male and female patients. I created an R shiny application to aid the use of our risk score algorithms in practice:

Acute HIV infection (AHI) detection is challenging in most populations due to low prevalence. However, we show in our new paper in JAIDS that using risk score algorithms in STI clinics in Malawi can greatly improve the efficiency of AHI detection.
