Q

19th Century

A
  • The age of industrialization led to an increase in population and crowding that without running water and disposal systems, the waste was dumped onto the streets or in rivers which caused disease to become rampant
  • Industrialization caused an overburdened workforce and a crowded dwelling producing a more susceptible population
  • Edwin Chadwick conducted studies of the health of working-class and proposed the Sanitary Idea (build a drainage network to remove sewage and wastes to remove diseases) –> Public Health Act of 1848
  • In 1869, Massachusetts set up a state board of health and used Lemuel Shattucks findings to shape the American Public Health System –> development of health departments

Inequities and Health Disparities:
- factors such as race, ethnicity, socioeconomic status, and geographic location
- marginalized communities have limited access to healthcare, etc

Chronic Disease Burden
- such as heart disease, diabetes, and obesity
- burden on HC system leading to increased HC costs, reduced quality of life, and death

Mental Health Crisis
- such as anxiety, depression, substance abuse disorder,
- lacks adequate resources and access to care

Opioid Epidemic:
- high rates of opioid addiction, overdose deaths,
- requires multifaceted approach (prevention, treatment, harm reduction)

Infectious Diseases
- such as COVID-19 shows a need for robust preparedness and response systems

Vaccine Hesitancy:
- misinformation has led to decreased vaccination rates for preventable diseases
- risk of lack of community immunity and disease outbreaks

Climate Change:
- extreme weather, changing disease patterns, increasing temperatures, air pollution, water contamination

Aging Population:
- challenges to chronic diseases, long term care needs, and strain on resources

Healthcare Access & Affordability:
- lack of insurance coverage and high out-of-pocket costs can prevent individuals from getting timely care

Data Privacy and Security
- balance data-sharing for benefits but safeguarding individual rights

Workforce Shortages:
- hinder the delivery and quality of public health services

Public Health Infrastructure:
- underfunded and lack modern infrastructure limiting their ability to respond effectively
