Disease forecasts are like weather forecasts: We cannot predict the finer details of a particular outbreak or a particular storm, but we can often identify when these threats are emerging and prepare accordingly.
The viruses that cause avian influenza are potential threats to global health. Recent animal outbreaks from a subtype called H5N1 have been especially troubling to scientists. Although human infections from H5N1 have been relatively rare, there have been a little more than 900 known cases globally since 2003 – nearly 50% of these cases have been fatal – a mortality rate about 20 times higher than that of the 1918 flu pandemic. If the worst of these rare infections ever became common among people, the results could be devastating.
Approaching potential disease threats from an anthropological perspective, my colleagues and I recently published a book called “Emerging Infections: Three Epidemiological Transitions from Prehistory to the Present” to examine the ways human behaviors have shaped the evolution of infectious diseases, beginning with their first major emergence in the Neolithic period and continuing for 10,000 years to the present day.
Viewed from this deep time perspective, it becomes evident that H5N1 is displaying a common pattern of stepwise invasion from animal to human populations. Like many emerging viruses, H5N1 is making incremental evolutionary changes that could allow it to transmit between people. The periods between these evolutionary steps present opportunities to slow this process and possibly avert a global disaster.
Spillover and viral chatter
When a disease-causing pathogen such as a flu virus is already adapted to infect a particular animal species, it may eventually evolve the ability to infect a new species, such as humans, through a process called spillover.
Spillover is a tricky enterprise. To be successful, the pathogen must have the right set of molecular “keys” compatible with the host’s molecular “locks” so it can break in and out of host cells and hijack their replication machinery. Because these locks often vary between species, the pathogen may have to try many different keys before it can infect an entirely new host species. For instance, the keys a virus successfully uses to infect chickens and ducks may not work on cattle and humans. And because new keys can be made only through random mutation, the odds of obtaining all the right ones are very slim.
Given these evolutionary challenges, it is not surprising that pathogens often get stuck partway into the spillover process. A new variant of the pathogen might be transmissible from an animal only to a person who is either more susceptible due to preexisting illness or more likely to be infected because of extended exposure to the pathogen.
Even then, the pathogen might not be able to break out of its human host and transmit to another person. This is the current situation with H5N1. For the past year, there have been many animal outbreaks in a variety of wild and domestic animals, especially among birds and cattle. But there have also been a small number of human cases, most of which have occurred among poultry and dairy workers who worked closely with large numbers of infected animals.
Pathogen transmission can be modeled in three stages. In Stage 1, the pathogen can be transmitted only between nonhuman animals. In stage 2, the pathogen can also be transmitted to humans, but it is not yet adapted for human-to-human transmission. In Stage 3, the pathogen is fully capable of human-to-human transmission.Ron Barrett, CC BY-SA
Epidemiologists call this situation viral chatter: when human infections occur only in small, sporadic outbreaks that appear like the chattering signals of coded radio communications – tiny bursts of unclear information that may add up to a very ominous message. In the case of viral chatter, the message would be a human pandemic.
Sporadic, individual cases of H5N1 among people suggest that human-to-human transmission may likely occur at some point. But even so, no one knows how long or how many steps it would take for this to happen.
Influenza viruses evolve rapidly. This is partly because two or more flu varieties can infect the same host simultaneously, allowing them to reshuffle their genetic material with one another to produce entirely new varieties.

These reshuffling events are more likely to occur when there is a diverse range of host species. So it is particularly concerning that H5N1 is known to have infected at least 450 different animal species. It may not be long before the viral chatter gives way to larger human epidemics.
Reshaping the trajectory
The good news is that people can take basic measures to slow down the evolution of H5N1 and potentially reduce the lethality of avian influenza should it ever become a common human infection. But governments and businesses will need to act.
People can start by taking better care of food animals. The total weight of the world’s poultry is greater than all wild bird species combined. So it is not surprising that the geography of most H5N1 outbreaks track more closely with large-scale housing and international transfers of live poultry than with the nesting and migration patterns of wild aquatic birds. Reducing these agricultural practices could help curb the evolution and spread of H5N1.

People can also take better care of themselves. At the individual level, most people can vaccinate against the common, seasonal influenza viruses that circulate every year. At first glance this practice may not seem connected to the emergence of avian influenza. But in addition to preventing seasonal illness, vaccination against common human varieties of the virus will reduce the odds of it mixing with avian varieties and giving them the traits they need for human-to-human transmission.
At the population level, societies can work together to improve nutrition and sanitation in the world’s poorest populations. History has shown that better nutrition increases overall resistance to new infections, and better sanitation reduces how much and how often people are exposed to new pathogens. And in today’s interconnected world, the disease problems of any society will eventually spread to every society.
For more than 10,000 years, human behaviors have shaped the evolutionary trajectories of infectious diseases. Knowing this, people can reshape these trajectories for the better.Ron Barrett, Professor of Anthropology, Macalester College

Identifying brands as Black-owned can pay off for businesses Draft
A study reveals that labeling restaurants as Black-owned boosts sales and traffic, particularly in liberal areas, highlighting the potential of visibility for minority-owned businesses.
In June 2020, the business-review website Yelp introduced a feature allowing consumers to search for Black-owned restaurants. As professors who study digitization, inequality and the economics of technology, we were interested in understanding its effect. So we analyzed more than two years of data from Yelp.
We found that restaurants labeled as Black-owned saw a 65% increase in online traffic, more searches and calls, and higher sales through food orders and in-person visits. These results suggest that for many Black-owned businesses, a simple change in their visibility can create new opportunities for growth.
However, the impact varied by location. The gains were strongest in politically liberal areas and places with lower levels of implicit racial bias, as measured by regional variation in implicit-association test scores. This suggests that platforms are in part channeling, as opposed to creating, customer demand. Interestingly, white customers drove most of the increase, suggesting the label helped raise awareness of businesses they might not have considered before.
This wasn’t just a 2020 trend – in follow-up analyses, we found similar results among businesses that opted into the feature later. We also collaborated with the online furniture company Wayfair, which launched a “Black Maker” label on its site in 2023, and found that it led to a 57% increase in web traffic. Finally, Yelp rolled out a Latino-owned label on the platform late that year, which led to a similar increase in consumer engagement.
Why it matters
This research has implications for business owners, digital platforms and policymakers. Growing awareness of racial inequality – partially driven by the Black Lives Matter movement, especially after the murder of George Floyd in 2020 — has led to increased corporate and customer interest in supporting minority-owned businesses. It also led many companies to make commitments to promote racial equity.
However, more recently, many companies have dismantled these efforts. For instance, Target recently announced that it was eliminating its program to spotlight Black-owned businesses. Our findings suggest that increasing the visibility of minority ownership – a relatively low-cost change – can substantially improve economic outcomes for Black-owned businesses.

Our results also show that diversity initiatives aren’t just about warm and fuzzy feelings. Businesses should measure and evaluate their impact to ensure their programs are effective. A well-designed program can benefit the bottom line, while a poorly designed one risks being ineffective or even counterproductive.
So it’s important to acknowledge the potential risks. Past research, including some of our own, indicates that revealing racial identity sometimes can lead to discrimination or backlash. While our findings suggest that labeling can have positive effects, a poorly implemented policy can backfire. Yelp’s initiative design empowered users looking to support Black-owned businesses while allowing other users to continue searching in alternative ways.
That means policy design is crucial. What matters isn’t just what information is revealed, but also how it’s communicated. Our analysis shows that customer demand and preferences vary considerably across locations and demographics, meaning that context also matters.
What still isn’t known
While our research suggests that businesses experienced economic benefits from adopting the label, it’s crucial to understand which policy designs work best in the long run. For instance, Yelp’s program used an opt-in feature, which may have contributed to its success.
However, open questions remain. How are platforms affected by labeling businesses? What other types of labels might be impactful, and for which types of businesses? Could some interventions backfire?
Another key question is, which customers respond to racial identity disclosures? Recent advances in data analytics can help companies refine their strategies, making it easier to target the right consumer groups for more effective initiatives.
Ultimately, our study is a step toward understanding how transparency and visibility can shape economic outcomes. It highlights a diversity initiative that has benefited both customers and businesses, and provides a road map for companies that want to design initiatives that matter. And, more broadly, it speaks to a question facing all companies: How can companies better understand and shape their societal footprint?
