👉 Metropolitan infection, often referred to as urban or metropolitan infectious disease, is a term used to describe diseases that spread rapidly within densely populated urban areas. These infections thrive in environments where close human contact and poor sanitation are common, facilitating the transmission of pathogens through various routes such as person-to-person contact, contaminated surfaces, or air. Common examples include respiratory infections like influenza and COVID-19, gastrointestinal illnesses like norovirus, and vector-borne diseases like dengue fever. The high population density, often coupled with inadequate healthcare infrastructure and sanitation, exacerbates the spread of these infections, making urban settings particularly vulnerable to outbreaks and requiring robust public health measures for prevention and control.
