Technological Advances/Limitations: Disease After 1900 - AP World History
- What medical imaging technology became widespread after World War II?
- X-rays. Discovered in 1895, became standard diagnostic tool post-WWII.
- Identify the vector responsible for transmitting malaria.
- Anopheles mosquito. Female mosquito transmits malaria parasites through bites.
- Which disease outbreak in 2014 highlighted the importance of rapid response?
- Ebola. West African outbreak demonstrated need for global preparedness.
- What is the primary role of the Centers for Disease Control and Prevention (CDC)?
- Protect public health. US federal agency monitoring and preventing disease outbreaks.
- What is the goal of the Global Polio Eradication Initiative?
- Eradicate polio. Worldwide campaign to eliminate polio through vaccination.
- Identify one advantage of point-of-care testing in disease diagnosis.
- Immediate results. Rapid testing enables quick diagnosis and treatment decisions.
- Identify the first vaccine developed using mRNA technology.
- COVID-19 vaccine. Pfizer-BioNTech and Moderna vaccines used mRNA technology.
- What is the primary method to prevent the spread of vector-borne diseases?
- Vector control. Eliminates mosquitoes and other disease-carrying organisms.
- What was one major limitation of antibiotics discovered after 1900?
- Antibiotic resistance. Overuse led to bacteria evolving resistance mechanisms.
- What is the main purpose of quarantine as a public health measure?
- Prevent disease spread. Isolates infected individuals to break transmission chains.
- What technological advance enabled mass production of vaccines post-1900?
- Recombinant DNA technology. Allows genetic engineering of vaccine components in labs.
- Identify the primary goal of the Human Genome Project completed in 2003.
- Map all human genes. Identified genetic basis for many diseases and treatments.
- What is one significant limitation of vaccines discovered for viral diseases?
- Mutating viruses. Viruses change genetic structure, making vaccines less effective.
- Identify the disease eradicated by the Global Smallpox Eradication Program.
- Smallpox. Eradicated through global vaccination campaign by 1980.
- Identify a major limitation of monoclonal antibodies in disease treatment.
- High cost. Expensive production limits widespread therapeutic use.
- What was a major public health achievement in the 20th century related to water?
- Water fluoridation. Dramatically reduced tooth decay and dental disease globally.
- Identify the first disease for which a vaccine was developed using recombinant DNA technology.
- Hepatitis B. First genetically engineered vaccine approved in 1986.
- What is the primary advantage of personalized medicine in disease treatment?
- Tailored treatments. Uses genetic information to customize individual patient care.
- Which disease was significantly reduced by the introduction of insecticide-treated nets?
- Malaria. Nets protect sleeping individuals from infected mosquitoes.
- What is one challenge of global health initiatives post-1900?
- Resource allocation. Limited funding creates inequitable access to healthcare.
- What is the primary function of antiviral drugs?
- Inhibit viral replication. Blocks viral reproduction within infected cells.
- Which pandemic in 1918 led to millions of deaths worldwide?
- The Spanish flu. H1N1 influenza killed 50-100 million people globally.
- Which pandemic in the late 20th century highlighted the need for global health cooperation?
- HIV/AIDS. Required unprecedented international collaboration and research.
- Identify the organization responsible for declaring global health emergencies.
- World Health Organization (WHO). UN agency with authority to coordinate international health responses.
- What is the primary advantage of telemedicine in disease management?
- Remote patient care. Provides medical care without geographic barriers.
- What is the key advantage of mRNA vaccines introduced in the 21st century?
- Rapid development. Can be designed and produced much faster than traditional vaccines.
- Identify the first antiviral drug approved for the treatment of HIV/AIDS.
- AZT (Zidovudine). First drug to slow HIV progression, approved in 1987.
- What is a major challenge in combating emerging infectious diseases after 1900?
- Rapid pathogen mutation. Pathogens evolve faster than treatment development.
- Identify the technology that allowed for the rapid sequencing of viral genomes.
- Next-generation sequencing. High-speed DNA sequencing enables rapid pathogen identification.
- Identify a key benefit of digital health technologies in managing diseases.
- Real-time data collection. Enables immediate tracking and response to disease outbreaks.
- What is the role of public health campaigns in disease prevention post-1900?
- Educate and promote health practices. Inform populations about prevention and healthy behaviors.
- Which institution was founded in 1948 to address global health issues?
- World Health Organization (WHO). International body coordinating global health responses.
- Which disease saw a resurgence due to vaccine hesitancy in the 21st century?
- Measles. Declining vaccination rates led to increased outbreaks.
- Which disease was declared eradicated worldwide in 1980?
- Smallpox. Last naturally occurring case reported in Somalia, 1977.
- Which medical advancement has improved early detection of diseases post-1900?
- Diagnostic imaging. CT, MRI, and ultrasound detect diseases before symptoms appear.
- Which disease was targeted by the first successful vaccine developed by Jonas Salk?
- Polio. First successful vaccine against paralytic disease in 1955.
- What was the impact of penicillin's discovery on infectious diseases?
- Penicillin revolutionized bacterial infection treatment. First widely effective antibiotic, saving millions of lives.
- What is the primary focus of epidemiological studies after 1900?
- Disease distribution and determinants. Studies patterns, causes, and control of disease spread.
