A healthier future starts with seeing the human causes of wildlife diseases.
 
When new diseases spread, news reports often focus on wildlife culprits—rodents, monkeys and mpox; bats and COVID-19; waterfowl and avian flu; or mosquitoes and Zika. But, in this urgent and engaging book, we see it often works the other way around—humans have caused diseases in other animals countless times, through travel and transport, the changes we impose on our environment, and global warming. With science journalist Liz Kalaugher as our guide, we meet the wildlife we have harmed and the experts now studying the crosscurrents between humans, other animals, and health.
 
Herds of buffalo in Kenya, cloned ferrets in Colorado, and frogs shipped worldwide as living pregnancy tests for humans, all help Kalaugher dive into the murky backstories behind wildlife epidemics past and present. We learn that military conflict likely contributed to the spread of rinderpest, or cattle plague, throughout Africa, devastating pastoral communities. That crowded poultry farms may create virulent new forms of bird flu that spill back into the wild. And that West Nile virus—which affects not only birds and humans, but other animals, including horses, skunks, and squirrels—is spreading as global temperatures rise.
 
Expanding today’s discussions of environmental protection to include illness and its impact, Kalaugher both sounds the alarm and explores ways to stop the emergence and spread of wildlife diseases. These solutions start with a simple lesson: when we protect other animals, we protect ourselves.

A decade-long study of young adulthood in Malawi that demonstrates the impact of widespread HIV status uncertainty, laying bare the sociological implications of what is not known.

An Epidemic of Uncertainty advances a new framework for studying social life by emphasizing something social scientists routinely omit from their theories, models, and measures–what people know they don’t know. Taking Malawi’s ongoing AIDS epidemic as an entry point, Jenny Trinitapoli shows that despite admirable declines in new HIV infections and AIDS-related mortality, an epidemic of uncertainty persists; at any given point in time, fully half of Malawian young adults don’t know their HIV status. Reckoning with the impact of this uncertainty within the bustling trading town of Balaka, Trinitapoli argues that HIV-related uncertainty is measurable, pervasive, and impervious to biomedical solutions, with consequences that expand into multiple domains of life, including relationship stability, fertility, and health. Over the duration of a groundbreaking decade-long longitudinal study, rich survey data and poignant ethnographic vignettes vividly depict how individual lives and population patterns unfold against the backdrop of an ever-evolving epidemic. Even as HIV is transformed from a progressive, fatal disease to a chronic and manageable condition, the accompanying epidemic of uncertainty remains fundamental to understanding social life in this part of the world.

Insisting that known unknowns can and should be integrated into social-scientific models of human behavior, An Epidemic of Uncertainty treats uncertainty as an enduring aspect, a central feature, and a powerful force in everyday life.
