Technological Advances and Limitations after 1900: Disease - AP World History Study Guide
Introduction
Ready to dive into the world of diseases? (No, not literally, please wash your hands first! 😷) From the Spanish Flu to COVID-19, we’ll explore how advancements in technology have shaped our battles against diseases in the modern era. Get your vaccines ready, and let’s conquer some germs! 🦠💉
Pandemics and Epidemics: A Global Tag Team
Remember SARS-CoV-2, also known as COVID-19? Yes, that little virus that turned our lives upside down! While the AP World History exam might consider it too recent to be "history," it's a perfect example of how rapidly the medical community responds to pandemics. The COVID-19 pandemic saw the development of multiple vaccines faster than you can say "I need a mask!" mRNA and adenovirus-based vaccines, such as those from Pfizer and Johnson & Johnson, showcased different approaches to fighting the same virus. Vaccines are truly like superheroes with different powers—some fly, some shoot webs, and some teach your cells how to make spike proteins. 🦸♀️🦸♂️
Another notorious pandemic was the Spanish Flu of 1918. This flu originated during World War I and tore through American cities, particularly those with military bases. With around 195,000 Americans losing their lives in October 1918 alone, it spread like wildfire because soldiers and their loved ones reunited just in time for the flu to crash the armistice party. Despite lacking a vaccine, efforts to encourage handwashing and social distancing back then echo our modern practices.
Contagious vs. Chronic: The Disease Battle Royale
Diseases come in two main flavors: contagious and chronic. Contagious diseases, like the flu and COVID-19, are social butterflies—they love to hop from one host to another. Chronic diseases, on the other hand, are more like hermits; you can’t catch them from someone else. They typically arise due to genetics or lifestyle—think heart disease, diabetes, and Parkinson’s disease.
In More Developed Countries (MDCs), chronic diseases often take the stage. This is partly because life expectancy is higher, giving chronic conditions time to develop. On the other hand, Less Developed Countries (LDCs) still grapple with contagious diseases due to lower life expectancies and less access to healthcare.
But everywhere, pandemics show no favoritism. The Spanish Flu and COVID-19 hit globally, highlighting how interconnected our world is in the age of globalization. Essentially, with great travel comes great responsibility—try not to spread germs! ✈️🌍
HIV/AIDS: A Deadly Misunderstanding
Let’s rewind a bit to the late 1900s in New York City and San Francisco, where HIV/AIDS first emerged and was initially labeled as GRID (Gay-Related Immunodeficiency). This early name reflected a significant misunderstanding and stigma, as the disease was first noticed mainly among gay men. However, it was later found that HIV/AIDS could also be transmitted through blood, affecting other populations too.
Fast forward to the 2010s, and science gives us PrEP (Pre-Exposure Prophylaxis), a medication like Truvada that can almost entirely prevent HIV if taken correctly. Today, HIV/AIDS remains a significant challenge, particularly in Sub-Saharan Africa, where lack of access to contraception contributes to its spread. NGOs continue to work on improving access to these vital resources.
Other Major Diseases in the Spotlight 🦟
Different diseases have different passports, traveling and troubling regions based on vectors and environments:
- Malaria: Spread by mosquitoes, this disease primarily affects tropical regions and kills 600,000 people annually. Antiparasitic treatments are used, and it’s a concern for both MDCs and LDCs.
- Tuberculosis (TB): An airborne infection, TB is a sneaky culprit that mainly affects Africa and the West Pacific. Antibiotics are the go-to treatment here, with LDCs bearing the brunt.
- Cholera: Spread through contaminated water, cholera wreaks havoc in places like Asia, Africa, and Central America. It kills 100,000 people annually, with treatment focusing on IV fluids and antibiotics.
Age and Behavior-Related Diseases
Thanks to vaccines and modern medicine, diseases like smallpox and measles are largely history. But, as people age and behaviors change, new health issues appear:
- Alzheimer’s Disease: Showing up almost exclusively in senior citizens, this condition reflects the neurological changes that come with old age.
- Heart Disease and Diabetes: Stem from behavioral factors like diet and exercise (or lack thereof). With technological advancements promoting sedentary lifestyles and high-calorie diets, these diseases are on the rise.
Key Terms to Keep in Your Medical Kit 🩺

Conclusion
From the Spanish Flu to COVID-19 and beyond, our battle against diseases is an ongoing saga. The story of medical advancements is one of both successes and limitations, highlighting the crucial role of technology and globalization in our health. As we continue to advance, each step forward helps turn the tide against the invisible enemies we face.
