Answer :
In the modern era, urbanization has increased the risk of disease epidemics primarily due to the following reasons:
1. Overcrowding in urban areas facilitates the rapid spread of diseases among a large population. When people live in close proximity to each other, it becomes easier for pathogens to jump from one person to another, leading to the quicker transmission of infectious diseases.
2. Urban areas often face challenges in maintaining adequate sanitation and hygiene standards, which are crucial for disease prevention. Factors like limited access to clean water, sanitation facilities, and proper waste disposal systems can create breeding grounds for disease-causing agents, contributing to the increased risk of epidemics.
3. The high population density in urban areas can strain healthcare systems, leading to difficulties in effectively managing and controlling disease outbreaks. Limited access to healthcare facilities, medical resources, and healthcare professionals in densely populated cities can impede timely diagnosis, treatment, and containment of diseases, further exacerbating the risk of epidemics.
4. Globalization and increased connectivity in urban centers allow diseases to spread more rapidly across borders. Urban areas serve as hubs for travel, trade, and migration, facilitating the rapid movement of pathogens between different regions and countries, heightening the risk of epidemics on a larger scale.
Overall, the combination of factors such as overcrowding, inadequate sanitation, limited healthcare resources, and global connectivity in urban areas collectively contribute to the heightened risk of disease epidemics in the modern era.
