What field of medicine treats infectious diseases?

The field of medicine that specifically focuses on the treatment of infectious diseases is known as Infectiology. This specialization targets the diagnosis, treatment, and prevention of diseases caused by bacteria, viruses, fungi, and parasites. Infectious disease specialists are equipped with a comprehensive understanding of how these pathogens interact with the human body and how to effectively combat them.

While immunology studies the immune system and its response to pathogens, including how the body defends itself against infectious diseases, it is not solely dedicated to treating those diseases directly.

Similarly, pulmonology relates to diseases of the respiratory system and would address respiratory infections, but it does not encompass the broader field of infectious diseases.

Cardiology focuses on heart and vascular diseases, which are unrelated to infectious diseases. Each of these fields serves important roles in medicine, but Infectiology is the specific discipline that addresses the diagnosis and treatment of infectious diseases.
