Primates and Human Diseases: Understanding Transmissible Pathogens Between Apes and Humans

Introduction

The study of diseases in primates has taken on increased significance due to their close genetic relationship with humans. Monkeys and apes frequently suffer from diseases that are common among humans, and this draws attention to the importance of proper husbandry, research practices, and conservation efforts to minimize the spread of these pathogens. We will explore the frequency and nature of human diseases that monkeys, particularly apes, can suffer from, highlighting the risk factors, preventive measures, and the impact on both primate and human health.

Why Monkeys Get Human Diseases

Monkeys can easily contract human diseases due to their close genetic similarity to humans. As a result, zoos and scientific researchers must take precautions to manage these risks. One notable example involves the regulation of food intake, as overfeeding with foods high in sugar such as bananas can lead to diabetes and other maladies.

Frequency of Human Disease in Monkeys

While the frequency of human diseases in monkeys is not always quantified, it is potentially frequent. One study in Africa found that 58% of chimpanzees carried Staphylococcus aureus bacteria, likely transmitted from the veterinarians and researchers working with them. This highlights the need for stringent hygiene measures and research protocols to minimize disease transmission.

Common Human Diseases in Monkeys

Both apes and other primates can suffer from common human diseases such as diabetes and psoriasis. Psoriasis, for instance, can affect the dermal changes in monkeys, showing tortuous capillary loops and benign inflammatory infiltrate in the papillary dermis. These symptoms are indicative of the human skin disease psoriasis vulgaris, underscoring the potential for direct transmission of such conditions.

Respiratory Diseases and Other Pathogens

Respiratory diseases, including the common cold, human respiratory syncytial virus (HRSV), and human metapneumovirus (HMPV), have been identified in chimpanzees and other primates. For example, in 2013, many chimpanzees from Uganda contracted the common cold and developed pneumonia in 2016 from another virus, resulting in significant fatalities.

Impact of Human Contact on Primates

Despite the close biological relationship, human contact with primates can have negative consequences. The study of chimpanzees in Africa, for instance, inadvertently led to a higher incidence of diseases among the apes. However, these scientific endeavors brought an unexpected positive outcome. The attention garnered by these studies helped to reduce poaching, as researchers and visitors acted as protectors. The Max Planck Institute for Evolutionary Anthropology reported that more lives were saved despite the presence of these diseases.

Preventive Measures and Conservation

Veterinarians use protective measures such as masks to prevent exchanging diseases with chimpanzees. These efforts are crucial in maintaining both primate and human health. It is essential to continue studying these animals to understand disease transmission better and implement effective preventive measures.

Conclusion

The transmission of human diseases to primates, particularly apes, highlights the importance of proper care, research practices, and conservation efforts. While the frequency of these transmissions might not always be accurately quantified, the potential for significant impacts on both primate and human health mandates continuous attention and vigilance.
