Legacy of a Gentle Warrior

Al Poussaint (L) and Mario Cooper (R), 1996
Mario Cooper speaking at the Leading for Life Campaign in 1996, with Dr. Alvin Poussaint of Harvard Medical School

Last weekend I attended a memorial for an old friend, Mario Cooper. Mario was on our International Advisory Council at the Harvard AIDS Initiative for many years. The gathering was held in the two-story, Washington, D.C. apartment of Peggy Cooper Cafritz, one of Mario’s sisters. On that bright, sunny September Sunday, her place filled up with family, old friends, and lots of funny and loving stories about Mario from all parts of his past. Peggy’s art-filled flat was also filled by so many who loved Mario that it felt like he was there with us.

Mario died a couple months ago, but he was very much alive in the stories, laughter, and tears of those of us blessed to be there to honor this gentle warrior. In her remarks about Mario, Pam Horowitz, Julian Bond’s widow, noted that her husband had been planning to attend this memorial until his own sudden death in August. To Mario, Julian Bond had been a true hero.

One of the things that upset Mario about the HIV/AIDS epidemic was the disproportionate impact it was having on U.S. minorities and within minority communities. When the first five cases of what would later be called AIDS were reported from doctors in Los Angeles in 1981, Mario later noted, two of the five men were minorities. That would be 20% of the first five cases. Today, the proportion of African Americans that make up the AIDS cases in our country is at 41% and among Latino Americans it is 20%.

What to we do about this situation? What Mario did was to do what he was good at. He organized political meetings and a campaign to address the crisis for African Americans. The meeting was a unique one.

Mario’s Leading for Life summit took place in 1996. The campaign, which we hosted at Harvard, involved one hundred influential African American leaders. Mario got Marion Wright Edelman, founder of the Children’s Defense Fund, and Alexis Herman, the highest-ranking African American in the U.S. government at the time to come. Also attending were David Satcher, Director of the CDC and soon to be Surgeon General, along with intellectuals and activists such as Julian Bond, Henry Louis (Skip) Gates, Alvin Poussiant and Cornell West. With my help, and the outreach of others in the “AIDS world” such as Helene Gayle, Eric Goosby, Phil Wilson and Cornelius Baker, and the help from leaders in the non-AIDS world, such as Reverend Edwin Sanders, singer Billy Porter and others from Leading for Life, intense lobbying of the Congressional Black Caucus in Congress was undertaken. Eventually $156 million was appropriated by the Clinton administration at the Caucus’ urging to specifically help with AIDS crisis in the African American community.

Mario made this happen. He was a skillful politician, and he knew he was most effective behind the scenes and not in the limelight. When he finally agreed to an interview with The Washington Post about the campaign and the Congressional Black Caucus’s success in getting the $156 million, he called the amount “chump change compared to what is really going to be needed” to turn the epidemic around in America’s minority communities. Mario did not mince words.

Unfortunately, Mario was right. Fast forward two decades since the Leading for Life campaign and our efforts to combat AIDS in minority communities has not altered the disproportionate impact the epidemic is having. Black men account for an estimated 44% of new infections in our country. Once living with HIV infection, African Americans have an age-adjusted death rate that is more than twice that of white Americans with HIV. The U.S. Hispanic populations also continue to be disproportionately affected and infected. We are still failing when it comes to affecting true change.

As a black man from Mobile Alabama, Mario Cooper certainly knew the deck was stacked against minorities. The culprits that need to be addressed in our society are inequity, poverty, and marginalization. Mount a campaign against these evils that disproportionately affect minorities and we mount a truly successful campaign against AIDS in minority communities. Access to HIV testing and equal access to care and treatment are needed. Now.


  • Expand the use of clean needle exchange that has been proven to work and does not promote drug use.
  • Expand targeted Pre-exposure prophylaxis (PrEP) programs that use anti-HIV drugs prior to exposure to HIV to prevent infection.
  • Expand testing so that all people living with HIV will know they are infected.
  • Provide immediate access to treatment for the infected to help their own health and to prevent the spread of the virus to others.
  • And last, but certainly not least, make basic health services a right for all. Build a real and functional safety net for those in need of basic and preventative health care in our America.

Mario would have wanted the National Urban League, the Congressional Black Caucus and other minority leadership organizations to actually lead and demand these actions. I would say that national “leadership organizations” who really want to lead are trying, and our two national political parties need to do the same. This is a path we can all agree upon. In fact, leaders, leadership organizations and the governments of the cities of Atlanta, Denver and San Francisco, and the State of New York, have recently signed on to end AIDS in their populations in the next 15 years by the needed actions listed above. The campaign and path Mario envisioned is spelled out for us. LET’S EACH JOIN, LEAD AND GET IT DONE.

Stopping a Good Investment in the Health of Africa

August is of course Winter in the southern hemisphere, but we are just finishing the “dog days of summer” here in Boston. As we do so at the Harvard T.H. Chan School of Public Health, our first class of Doctoral students in the newly refurbished Doctor of Public Health degree have been plugging away for the past two months. These superstars are working towards a doctoral degree in the actual “practice” of public health. They will learn how to be the next leaders in creating, implementing, and evaluating the impact of large public health programs, which will save literally hundreds of thousands, if not millions of lives. As in its name, our Doctor of Pubic Health course showcases What Works and Why: Building Successful Programs in Global Health.

Half of these exceptional students are from countries outside of the U.S. All are successful already in some area of health or public health. Their creative energy and intelligence have many of us old-timers at Harvard Chan feeling optimistic that the world can be changed for the better. But another recent development, the reduction of U.S. government funding of healthcare in Africa, is a cause for deep concern.

Training the next generation of health practitioners is vital to addressing the world’s pubic health needs. We are investing in many top medical and public health programs in countries with resources, such as ours. These are worthy investments. Unfortunately, much of the developing world has difficulty making such investments. In Africa especially, there is an extreme shortage of healthcare professionals available to provide basic treatment and prevention services. Africa has been estimated to have 25% of the world’s burden of diseases, but only 3% of the world’s healthcare workforce. The World Health Organization estimates that there is a minimum threshold of 23 doctors, nurses and midwives per 10,000 people in a country necessary to deliver just the most essential maternal and child health services. The majority of the countries in sub Saharan Africa do not even come close to meeting this minimum requirement.

Six years ago, our country’s President’s Emergency Plan for AIDS Relief (PEPFAR) created a small, but uniquely effective program to expand the number of doctors and nurses trained in developing countries, especially in those being devastated by the AIDS epidemic. Dr. Eric Goosby slipped the program into the PEPFAR plans as he took over leading the program when he became the PEPFAR AIDS Ambassador in 2009. Goosby quietly but quickly got the funding for the $60 million, five-year program called the Medical Education Partnership Initiatives (MEPI for short). The funding, granted directly to 14 African medical schools, went to improve medical training in Africa. These African medical schools then partnered with U.S. medical schools or in our case, the School of Public Health. In designing the MEPI program, Goosby understood that those in control should be the local leaders and organizations that would be leading, implementing, and sustaining the effort in the long run.

The MEPI program has advanced medical training for both doctors and nurses in dramatic ways these past five years. (see )

Last year, Goosby moved back to his home in San Francisco and UCSF, having successfully guided our government’s PEPFAR effort. As of this month, August, the U.S. government has decided to end most of the MEPI program, one of its most impactful programs in terms of expanding and improving the future healthcare workforce in Africa. (There is a smaller program continuing to network the few heads of the African schools and foster training in research, but the main effort across 32 African medical schools and other African institutions and their U.S. partners has not been continued.)

Funding which would have been used to continue the MEPI program will now go towards other important, but short-term efforts, in the PEPFAR program. I can’t imagine, though, a more valuable investment for the long-term health of Africa than to invest in correcting the severe shortage of healthcare workers in Africa. Many of the young leaders trained here at Harvard and across the developed world want to work in Africa to improve healthcare there. Yet without more skilled African doctors and nurses, there will be scant opportunity to improve and expand health systems in Africa. We can best invest in the health of Africa by investing in African health professionals and community health workers. We need to expand programs like MEPI, not eliminate them.

What is the Harvard T.H. Chan School of Public Health AIDS Initiative?

The Harvard T.H. Chan School of Public Health AIDS Initiative (HAI) is dedicated to research and education to end the AIDS epidemic in Africa and developing countries. Since 1988, HAI has been at the forefront of HIV/AIDS laboratory research, clinical trials, education, and leadership.

Since 1988, HAI has promoted research, education, and leadership to end the AIDS epidemic. As the number of AIDS cases rose disproportionately to affect Africa and other resource scarce settings, HAI has directed its efforts towards developing prevention and treatment strategies to stem the epidemic in these regions.

Training students, researchers, and health professionals is vital to HAI’s mission. Education and training opportunities at Harvard and in Africa help create a network of experts to direct the next generation of public health leaders. HAI  also partners with government agencies, NGOs, research centers, and private corporations to develop initiatives that advance the understanding and treatment of HIV/AIDS.HAI logo
