Brazil Eliminates Mother-to-Child Transmission of HIV

“The World Health Organization (WHO) has validated Brazil for the elimination of mother-to-child transmission (EMTCT) of HIV, making it the most populous country in the Americas to achieve this historic milestone…

Brazil met all the criteria for EMTCT validation, including reducing vertical transmission of HIV to below 2% and achieving over 95% coverage for prenatal care, routine HIV testing, and timely treatment for pregnant women living with HIV. In addition to meeting the targets of the validation, Brazil demonstrated the delivery of quality services for mothers and their infants, robust data and laboratory systems, and a strong commitment to human rights, gender equality and community engagement.”

Was COVID Also an Inequality Pandemic?

COVID slowed but couldn’t stop the fall in global inequality.

Summary: Recent debates have framed global inequality as rapidly worsening, particularly in response to the COVID-19 pandemic. Evidence from the Inequality of Human Progress Index indicates that, despite temporary setbacks, long-term declines in inequality across multiple dimensions of wellbeing have largely persisted, with global disparities remaining well below 1990s levels.


Affordability fears, talk of a “K-shaped” economy, and claims of a new Gilded Age have pushed inequality to the center of today’s policy debates. Calls for a worldwide wealth tax and other unprecedented measures are not treated as radical but as inevitable—across academianon-profitsthe press, and international organizations, including the United Nations.

The COVID-19 pandemic seemed to clinch the case. As economies contracted and progress in poorer countries stalled, it was easy to assume that decades of convergence between developed and developing countries had come to an end. The authors of one Oxfam paper, for example, proclaimed during the pandemic that “unparalleled action [is] needed to combat unprecedented inequality in the wake of COVID-19.”

New research suggests a more nuanced reality. The updated Inequality of Human Progress Index assesses how the pandemic affected progress toward a more prosperous and equal world.

The pandemic clearly slowed improvement in global living standards and interrupted the pace at which countries were becoming more equal. It did not, however, cancel out the long-term, positive trends. Even under the strain of COVID-19, its attendant lockdowns, and other forceful policy responses, global inequality across key measures of well-being remained lower than it was a generation ago.

The index looks beyond income alone. It measures inequality across eight dimensions that shape everyday life, including lifespan, child survival, nutrition, education, internet access, environmental safety, income, and political freedom. The index, which I co-authored with George Mason University economist Vincent Geloso, seeks to offer a fuller view of gaps in global development, taking into account more aspects of human well-being than any prior index of inequality.

The data show a substantial decline in global inequality over the past three decades as rising prosperity allowed poor countries to narrow gaps with rich ones. That pattern held through 2019. During the pandemic years of 2020 and 2021, progress slowed sharply and, in some areas, stalled or modestly reversed. Yet the earlier gains were not erased.

This distinction is important. COVID-19 was a severe shock. Life expectancy fell worldwide. School closures disrupted education. Economic activity and international trade declined, with especially devastating effects on low-income countries. The index reflects these setbacks. Inequality stopped falling at its earlier pace and, in some measures, edged upward slightly after years of progress. Still, the overall level of global inequality remained far below where it stood in the 1990s.

In a few areas, improvement continued even during the crisis. Internet access expanded rapidly, especially in poorer countries, reducing inequality in access to information to its lowest level on record. Faster regulatory approvals amid the pandemic helped bring more people online. In Kenya, for example, Alphabet’s high-altitude internet balloons were finally cleared in 2020, allowing rural areas to gain internet access for the first time. The project had been stalled in regulatory review for nearly two years before the crisis prompted action.

Not all the data were encouraging. Inequality in political liberty ticked up during the pandemic as many countries took a turn toward greater authoritarianism. Even with the long-term shift toward electoral democracy intact, the setback shows the importance of protecting political liberty during emergencies.

For all the turmoil, the damage across different measures of well-being was thankfully limited.

These findings complicate popular claims that the world is experiencing a runaway increase in inequality. Calls for a global wealth tax, massive new aid commitments, or other significant expansions of state redistribution often rest on the premise that trade and free enterprise have failed to deliver shared gains. The data suggest otherwise.

If anything, the pandemic highlighted how sensitive progress can be to disruptions in markets. Countries with greater economic freedom generally proved more resilient. In contrast, prolonged lockdowns and restrictions often imposed heavy costs on poorer populations, particularly in countries where remote work and online schooling were not viable options for most people.

The broader lesson is that global convergence is neither automatic nor guaranteed, but instead depends on certain conditions such as undisturbed markets, even as long-term progress has proven more robust than critics often assume.

Mistaken narratives about global inequality have real consequences. They shape public opinion and influence policymakers to embrace sweeping interventions. A more accurate assessment of recent history suggests a need for caution.

COVID-19 tested the global economy in ways few events in modern history have. It slowed human progress and exposed vulnerabilities. At the same time, it demonstrated the durability of the long-term trend toward lower global inequality. Preserving and strengthening the policies and institutions that made that progress possible, including economic and political freedoms, remains a better bet than assuming they have already failed. The gains of recent decades have left the world both better off and more equal.

A Single Infusion Could Suppress HIV for Years, Study Suggests

“For about a decade, scientists have had remarkable success curing some blood cancers by modifying a patient’s own immune cells to recognize and kill the malignant cells.

That same approach may help control H.I.V., among the wiliest of viruses, scientists will report on Tuesday. After a single infusion of immune cells engineered to recognize the virus, two people in a new study have suppressed their H.I.V. to undetectable levels, one of them for nearly two years.

The data is scheduled to be presented at a gene therapy conference in Boston, but the researchers shared an early copy with The New York Times.

The treatment is years, if not decades, from being widely available, but the study offers what scientists call “proof of concept,” and the tantalizing hope that a single shot could one day offer lifelong relief from H.I.V.”

Malaria Vaccine Saves Lives and Reduces Hospitalizations

“The arrival of the RTS,S malaria vaccine was a landmark moment; Ghana, Kenya and Malawi were the first countries in the world to offer it to their populations as part of a pilot project launched in 2019, and the World Health Organization (WHO) recommended it for wider use in 2021.

Early studies indicated that the vaccine had a 13% drop in all-cause mortality, and a comprehensive new study of the last four years of vaccine roll-out published in The Lancet has confirmed this figure. That translates to roughly one in eight deaths prevented…

The study tracked 158 clusters across the three countries, with 79 areas introducing the vaccine in 2019 and 79 serving as comparison areas that received it later. Surveillance was built on a network of more than 26,000 local reporters who notified researchers of child deaths in their communities, followed by home visits to confirm details.

The findings carry particular weight because of how the study was designed. Clusters were randomly assigned, baseline characteristics were balanced, and coverage of other interventions, including bed-nets, routine vaccines and care-seeking for fever, remained similar across implementation and comparison areas throughout the four years.

This means, say the researchers, that the drop in deaths can be  ‘confidently attributed’ to the vaccine itself rather than to other shifts in malaria care.”
