Across the world, animals are more than just sources of food or labor—they are sacred beings, symbols of status, spiritual guides, and integral members of many communities. From the veneration of cows in India, to the totemic importance of certain species among African clans, to the practice of animal sacrifice in various religious rituals, humans have a deep and complex relationship with animals. While these relationships often reflect rich cultural traditions and identities, they can also create unintentional health risks—especially in the form of zoonotic diseases, which are infections transmitted from animals to humans.
In recent years, the global health community has become increasingly aware of how cultural practices and traditional beliefs can either mitigate or amplify the risk of zoonotic spillovers. These risks are not just hypothetical. The emergence of diseases like Ebola, avian influenza, and even COVID-19 has been linked, in part, to the way humans interact with animals in culturally embedded ways.

Animals in Rituals and Religion
In many communities, animals are central to rites of passage, religious festivals, or traditional healing. In parts of West Africa, for instance, certain ethnic groups use bushmeat—including primates and rodents—in ancestral worship or healing ceremonies. These animals are often hunted in the wild, handled without gloves, and butchered without proper sanitation. In the context of spiritual importance, caution may be overlooked in favor of ritual purity. This increases exposure to bodily fluids—blood, saliva, or feces—that can carry pathogens.
In South Asia, cattle are revered and rarely slaughtered, but in rural areas where animals live in close proximity to people, there is frequent exposure to animal waste, urine, and skin. In both cases—ritual killing or peaceful coexistence—people are at risk of zoonotic infection, especially when sanitation is poor or when animals are not vaccinated or monitored for disease.
Cultural beliefs are not easily changed, nor should they be dismissed. But understanding them is crucial for designing respectful and effective public health strategies. Telling someone to stop a ritual that has been performed for generations is unlikely to succeed. Instead, health interventions must work with cultural leaders and traditional healers to adapt practices or introduce risk-reducing measures.

Traditional Healing and Animal Parts
In many societies, animal parts are used in traditional medicine. Pangolin scales, bat droppings, snake venom, and monkey bones are all believed to cure illnesses or protect against evil spirits in some cultures. These beliefs are deeply rooted and often intertwined with ideas of spiritual wellness, not just physical health.
The problem is that many of these animals carry viruses and bacteria that can jump to humans. Handling or consuming unregulated animal products, especially from wild species, increases the chances of zoonotic transmission. For example, bats are reservoirs for viruses like Nipah, Marburg, and coronaviruses. Yet in some cultures, bat soup is considered a delicacy or a healing broth.
Public health messaging must be sensitive to these practices. Shaming people for using traditional medicine only pushes the practice underground. Instead, community education can highlight safe alternatives, provide information about disease transmission, and promote veterinary care for animals used in medicine or food.

The Role of Gender and Livelihoods
Cultural practices around animals also intersect with gender roles. In many rural communities, women and girls are responsible for caring for small livestock like chickens, goats, and rabbits. Men may handle larger animals or hunt wild game. These roles mean that disease exposure varies by gender.
Women may clean animal shelters, assist in births, or handle raw milk, putting them at risk for diseases like brucellosis or leptospirosis. Men involved in hunting or butchering are exposed to bloodborne pathogens, especially when handling bushmeat. Understanding these roles is essential in targeting public health messages.
Moreover, for many families, animals are a source of income or food security. Asking people to stop keeping animals or eating meat isn’t practical. Instead, improving animal health through vaccination, safe handling practices, and clean slaughtering environments can reduce risks without threatening livelihoods.

Toward a More Humane, Human Approach
Addressing zoonotic risks in the context of cultural animal practices doesn’t mean erasing traditions. It means listening, understanding, and working with communities to co-create solutions. Anthropologists, public health workers, veterinarians, and local leaders all have a role to play in shaping interventions that are both effective and respectful.
Programs that have succeeded often begin with dialogue—not directives. For instance, involving religious leaders in promoting safe animal handling or building community-based surveillance systems that respect local customs can help prevent outbreaks without alienating the very people they aim to protect.
Ultimately, the human-animal relationship is a mirror of our values, beliefs, and ways of life. By honoring that relationship while introducing safer practices, we can reduce zoonotic risk—and build more resilient communities in the process.
