The Silent Threat: Chronic Zoonotic Diseases and Their Long-Term Impact on Human Health

In recent times, the world has witnessed several pandemics and epidemics that have affected the health and lives of millions globally. Diseases such as Ebola, SARS, and COVID-19 have brought the world to a standstill and highlighted the need to be proactive and prepared when it comes to infectious diseases. However, these diseases are just the tip of the iceberg when it comes to zoonotic diseases, and the long-term impact on human health needs to be explored.

Zoonotic diseases are diseases transmitted from animals to humans. The transmission can occur through several means, such as direct contact with animals or their body fluids, consumption of contaminated food or water, or through vectors such as mosquitos or ticks. The majority of emerging infectious diseases are zoonotic, with estimates suggesting that around 60-75% of all newly emerging and re-emerging infectious diseases in humans are of animal origin.

Chronic zoonotic diseases, also known as neglected zoonoses, are those that do not receive as much attention as the more high-profile diseases such as Ebola and COVID-19. These diseases, such as leptospirosis, toxoplasmosis, and brucellosis, can have devastating impacts on human health. Although these diseases do not cause sudden outbreaks or pandemics, they can lead to long-term health effects, such as organ damage and disability.

Chronic zoonotic diseases are particularly concerning because they are often underdiagnosed and underreported. This is due to the fact that their symptoms can easily be mistaken for other illnesses, and diagnosis requires specialized testing that is not always available in low-resource settings. As a result, the true burden of chronic zoonotic diseases on human health is not fully understood.

The impact of chronic zoonotic diseases is not just limited to human health. These diseases can also have serious economic consequences. For example, brucellosis in livestock, which is a common cause of the disease in humans, can lead to reduced milk production and decreased fertility, resulting in significant economic losses for farmers.

The prevention and control of chronic zoonotic diseases require a one-health approach. This approach recognizes the interconnectedness of human, animal, and environmental health and aims to address health issues that affect all three. Collaboration between public health, veterinary, and environmental health sectors is crucial for the prevention and control of chronic zoonotic diseases.

In conclusion, chronic zoonotic diseases are a silent threat to human health and the economy. These diseases may not receive as much attention as the more high-profile diseases, but their long-term impact can be devastating. A one-health approach is necessary for the prevention and control of chronic zoonotic diseases, and increased awareness and funding for control and research is needed to protect human and animal health and wellbeing.
