Humans and animals: increasing contacts, increasing infections.

Area of Science:

• Epidemiology
• Infectious Diseases
• One Health

Background:

• Zoonotic infections are a significant public health concern in the United States.
• Changes in human-animal interactions, organism importation, and species crossover are key drivers of emerging infectious diseases.
• Lyme disease, while not a classic zoonotic disease, represents a major public health challenge due to its high prevalence.

Purpose of the Study:

• To review the primary factors influencing changes in zoonotic infections affecting Americans.
• To discuss the epidemiological significance of Lyme disease in the context of emerging infectious threats.

Main Methods:

• Literature review of recent studies on zoonotic diseases and Lyme disease.
• Analysis of trends in animal-human interactions and organism importation.
• Epidemiological data review for Lyme disease prevalence.

Main Results:

• Shifting animal-human interactions are a primary driver of zoonotic infection dynamics.
• The identification and importation of novel organisms contribute to the changing landscape of infectious diseases.
• Lyme disease exhibits epidemic or near-epidemic prevalence in numerous regions, necessitating focused public health attention.

Conclusions:

• Understanding the drivers of zoonotic infections is crucial for public health preparedness.
• Integrated approaches considering animal, human, and environmental health (One Health) are essential for managing infectious disease threats.
• Continued surveillance and research on diseases like Lyme disease are vital for effective control strategies.
