What is the name for diseases that have increased significantly in humans recently?

The term that refers to diseases that have increased significantly in humans recently is "emerging infections." Emerging infections are those that are newly identified or have recently increased in incidence in a particular population or geographic area. This can occur due to various factors, such as changes in the environment, increased human-animal interactions, global travel, and changes in population dynamics or behavior.

Emerging infections are particularly significant in public health because they can lead to outbreaks and have the potential to spread rapidly through communities. This concept emphasizes the need for continuous surveillance and research to identify and respond to these new or re-emerging pathogens effectively.

While chronic infections refer to long-lasting conditions often requiring ongoing management, subacute infections describe diseases with symptoms that are intermediate in duration. Resurgent infections are those that were previously controlled but have seen a resurgence. None of these terms encompass the idea of newly recognized or significantly increased diseases in the same way that "emerging infections" does.
