Efforts over the past few years to end the COVID-19 pandemic clearly reveal how global health impacts individual wellbeing and national security. At NIH, the Fogarty International Center helps the other institutes become engaged with global health research, which investigates the dual burden of infectious disease and non-communicable disease.
Global health research also encompasses data science, economics, genetics, climate change science, and many other disciplines. For more than 50 years, Fogarty has been building partnerships among institutions in the U.S. and abroad, while training the next generation of scientists focused on universal health needs.
America’s investment in Fogarty has paid rich dividends
During the pandemic, in particular, we’ve seen researchers trained by our programs make scientific discoveries that contributed to international security. Take Jessica Manning, a former Fogarty fellow who now conducts malaria research in Phnom Penh, Cambodia. Her team at the Ministry of Health sequenced the viral strain of SARS-CoV-2, the cause of COVID-19, infecting the first Cambodian patient and documented early the spread of this novel coronavirus outside of China.
Similarly, Christian Happi, director of the African Centre of Excellence for the Genomics of Infectious Disease, Ede, Nigeria, sequenced the first SARS-CoV-2 genome in Africa. Happi was able to do it by adapting the sequencing and analytical pipelines that he’d created back when he was a Fogarty grantee studying Ebola.
In Botswana, Sikhulile Moyo leveraged the skills he’d acquired while supported by a Fogarty HIV research training grant with Max Essex, Harvard School of Public Health, Cambridge, MA, to track COVID-19 mutations for his country’s Ministry of Health. Last November, he alerted the world of a new Omicron variant. Within six weeks, Omicron became the dominant global strain, challenging the ability of COVID vaccines to control its spread. In the Dominican Republic, William Duke, a national commission member, used what he’d learned as a Fogarty trainee to help create a national COVID-19 intervention plan to prevent and control the disease.
Fogarty’s fostering of global health leaders is one way we advance scientific expertise while ensuring our nation’s biosecurity. Another is by finding effective ways to study abroad the same health conditions that affect our own population.
Research conducted in Colombia, for example, may provide clues for preventing Alzheimer’s disease in the U.S. Fogarty support brought together neuroscientists Kenneth Kosik, University of California, Santa Barbara, and Francisco Lopera, University of Antioquia, Colombia, to study members of the largest-known family with an early-onset, rapidly progressive form of the disease. Over the years, Kosik and Lopera have trained local scientists, explored gene therapy targets, investigated biomarkers to monitor disease progression, and conducted drug trials in search of a cure for Alzheimer’s.
Researchers in other fields also discover unique opportunities to investigate populations with high rates of disease. Siana Nkya, a Fogarty grantee based in Tanzania, has devoted her career to studying the genetic determinants of sickle cell disease, which affects many people around the world, including in the U.S. We hope that US-African partnerships might develop improved, affordable treatments and a cure for all patients with this devastating disease. Similarly, people in the U.S. have access to state-of-the-art HIV treatment studies in places around the globe where incidence rates are higher.
Fogarty has supported many milestone achievements in HIV research over the years. Among them is a study that took place in nine countries. The research, led by Myron Cohen of the University of North Carolina at Chapel Hill, established that antiretroviral therapy can prevent sexual transmission of HIV-1 among couples in which one person is infected and the other is not. In fact, this research informs current HIV treatment recommendations worldwide, including in the U.S.
Americans will also undoubtedly benefit from projects funded by Fogarty’s Global Brain and Nervous System Disorders Research across the Lifespan program. For example, psychologist Tatiana Balachova, University of Oklahoma, Oklahoma City, has designed an intervention for women in Russia to prevent fetal alcohol spectrum disorders. In another project in South Africa, Sandra and Joseph Jacobson, Wayne State University, Detroit, conducted the first-ever prospective longitudinal study of the syndrome. Findings from both projects are ripe for translation within an American context.
Other examples of Global Brain program investigations with broad implications in our own country include studying early psychosis in China; capacity building for schizophrenia research in Macedonia; exploring family consequences from the Zika virus in Brazil; and studying dementia and related health and social challenges in Lebanon.
These are just a few examples of Fogarty’s work and its unique mission. What is most remarkable about Fogarty is that just under 90 percent of our grants are co-funded by at least one other NIH institute, center, or office. Collaboration, both within borders and across them, is Fogarty’s formula for success.
Note: Dr. Lawrence Tabak, who performs the duties of the NIH Director, has asked the heads of NIH’s Institutes and Centers (ICs) to contribute occasional guest posts to the blog to highlight some of the interesting science that they support and conduct. This is the 22nd in the series of NIH IC guest posts that will run until a new permanent NIH director is in place.

In the early 1960s, reports began to surface that some children living in remote villages in East Africa were suffering mysterious episodes of “head nodding.” The condition, now named nodding syndrome, is recognized as a rare and devastating form of epilepsy. There were hints that the syndrome might be caused by a parasitic worm called Onchocerca volvulus, which is transmitted through the bites of blackflies. But no one had been able to tie the parasitic infection directly to the nodding heads.
Now, NIH researchers and their international colleagues think they’ve found the missing link. The human immune system turns out to be a central player. After analyzing blood and cerebrospinal fluid of kids with nodding syndrome, they detected a particular antibody at unusually high levels . Further studies suggest the immune system ramps up production of that antibody to fight off the parasite. The trouble is those antibodies also react against a protein in healthy brain tissue, apparently leading to progressive cognitive dysfunction, neurological deterioration, head nodding, and potentially life-threatening seizures.
The findings, published in Science Translational Medicine, have important implications for the treatment and prevention of not only nodding syndrome, but perhaps other autoimmune-related forms of epilepsy. As people in the United States and around the globe today observe the 10th anniversary of international Rare Disease Day, this work provides yet another example of how rare disease research can shed light on more common diseases and fundamental aspects of human biology.
