Answer Key
The 1918 Spanish Flu pandemic was one of the deadliest in history, infecting about one-third of the world's population and killing an estimated 50-100 million people.
Malaria is transmitted by infected female Anopheles mosquitoes. The disease is caused by Plasmodium parasites that infect and destroy red blood cells.
The Black Death was caused by the bacterium Yersinia pestis, spread by fleas on rats. It killed an estimated 25-50 million Europeans between 1347 and 1351.
Tuberculosis (TB) was called the 'White Plague' because of the extreme pallor of its sufferers. It was a leading cause of death in the 19th century.
Influenza is caused by influenza viruses. There are four types: A, B, C, and D. Types A and B cause seasonal epidemics, while Type A can cause pandemics.
John Snow identified a contaminated water pump on Broad Street as the source of a cholera outbreak, helping establish the waterborne theory of disease transmission.
HIV (Human Immunodeficiency Virus) causes AIDS (Acquired Immunodeficiency Syndrome). It was first identified in 1983 and attacks the immune system's CD4 cells.
African trypanosomiasis, or sleeping sickness, is caused by Trypanosoma parasites transmitted by the tsetse fly. It disrupts the sleep cycle and can be fatal if untreated.
Penicillin was first used to treat bacterial infections, particularly staphylococcal and streptococcal infections. It saved countless lives during World War II.
Rabies is transmitted through the bite of an infected animal, most commonly dogs, bats, and raccoons. The virus travels through the nervous system to the brain.
Herd immunity occurs when a sufficient percentage of a population is immune to an infectious disease, either through vaccination or prior infection, reducing its spread to vulnerable individuals.
Dengue fever is called 'breakbone fever' due to the severe muscle and joint pain it causes. It is transmitted by Aedes mosquitoes and affects millions of people annually.
An epidemic is a disease outbreak within a specific community or region, while a pandemic is an epidemic that has spread across multiple countries or continents.
Tuberculosis was called 'consumption' because of how the disease seemed to consume its victims, causing weight loss and wasting. It killed one in four Europeans in the 19th century.
Antibiotic resistance occurs when bacteria evolve to survive antibiotic treatment. Overuse and misuse of antibiotics accelerate this process, creating 'superbugs' that are difficult to treat.
