DeepSummary
The transcript discusses the phenomenon of reverse zoonoses, where animals catch diseases from humans. It focuses on how human respiratory diseases have severely impacted endangered great ape populations in Africa, often posing a bigger threat than habitat loss or poaching. Scientists like Tony Goldberg are studying how diseases spread from humans to apes and trying to find solutions to mitigate this problem.
Goldberg and his team discovered that children near Uganda's Kibali National Park were catching common human respiratory viruses at school and passing them asymptomatically to adults who then brought the diseases into the forests where chimpanzees live. Their research showed that focusing on improving children's health and hygiene could help reduce disease transmission to the apes.
While efforts are underway to update tourism guidelines and raise awareness, the transcript highlights challenges like lack of enforcement, economic incentives that discourage strict rules, and the need for more research into transmission pathways. However, scientists remain committed to finding ways to protect endangered great apes from deadly human diseases.
Key Episodes Takeaways
- Human respiratory diseases pose a severe threat to endangered great ape populations in Africa through reverse zoonosis transmission.
- Children catching viruses at school and passing them asymptomatically to adults who visit ape habitats may enable disease spread to the apes.
- Improving children's health and hygiene near great ape habitats could reduce transmission of human diseases to the apes.
- Lack of enforcement of existing tourism guidelines enables risky tourist behaviors that can transmit diseases to great apes.
- Economic incentives and fears of impacting tourism revenues hamper strict enforcement of disease prevention protocols.
- More research is needed on disease transmission pathways to develop and justify stricter hygiene measures for tourism and field work.
- Raising awareness and standardizing educational content for tourists and locals could help change behaviors to prevent reverse zoonoses.
- Cross-sector collaboration among scientists, conservationists, governments and communities is critical to protecting great apes.

The phenomenon of animals catching diseases from humans, called reverse zoonoses, has had a severe impact on great ape populations, often representing a bigger threat than habitat loss or poaching.
However, while many scientists and conservationists agree that human diseases pose one of the greatest risks to great apes today there are a few efforts under way to use a research-based approach to mitigate this problem.
