What is the meaning of the term "Zoonosis"?

The term "Zoonosis" refers specifically to diseases that are transmitted from animals to humans. This can occur through various means such as direct contact with infected animals, bites, or through vectors like ticks and mosquitoes that carry pathogens from animals to people. Understanding zoonotic diseases is crucial, especially for professionals involved in activities like diving, where contact with marine animal life can pose health risks.

In this context, options that suggest transmission in the opposite direction or indicate that the disease is specific to fish or caused solely by environmental factors do not accurately reflect the definition of zoonosis. Instead, zoonotic diseases can involve a wide range of animal hosts and are an important area of focus for public health due to their potential implications for human health.
