The following are places to go (some real and some virtual) to find out about disease cycles.

Read the Morbidity and Mortality Weekly Report from the CDC to find out the most current information about the cycles of disease. Check out the CDC's list of diseases and find out the natural history of each disease, how it is spread, how it is diagnosed, its distribution, its prevention and control, and more.
Travel to Ireland to understand how the cycle of a plant disease named Phytophthora infestans affected that country in the 1840s. Discover how dependent this country was on potatoes for its main food crop and how the potato blight spread throughout the land.
Pericles, one of the military leaders from Athens , had over 200,000 people flee from the outlying countryside and gather in Athens for protection from the pesky Spartans.

Take a trip to Mexico in the 1500s during the time of the Spanish invasion. The Europeans introduced diseases into Mexico and Central and South America that had a devastating impact on the native peoples.
Primary sources are original records created at the time historical events occurred. Read newspaper articles from the 1840s for historical perspective on the potato famine.
Site for kids explaining various bacteria, and ways to prevent infections and diseases.
He discovered that heating milk to high temperatures killed germs and thus made milk safer and more accessible for longer periods of time to the general public. He also figured out that certain diseases could be prevented through injecting people with a weakened form of the disease in order to build immunity.
Choose from this long list of medical issues to find out more about the spread of infectious diseases.
Get introduced to John Snow. In the 1850s, he discovered that the disease cycle of cholera was spread through water rather than through airborne sources.
These doctors are a part of a medical relief agency that helps victims of armed conflict, epidemics, natural and man-made disasters, and others who lack health care due to geographic remoteness or ethnic marginalization.
Meet Elizabeth Lee Hazen and Rachel Fuller Brown. They were pioneers in creating antibiotics in the 1950s.
In 1861, he observed that the patients of doctors who performed autopsies suffered from more infections than the patients of doctors who did not perform autopsies. From this, he concluded that infection was spread by the contaminated hands of doctors.
Meet Jonas Salk and learn how he developed a vaccine for polio. Prior to 1955, polio was a crippling disease to millions worldwide. Salk's vaccine has virtually eradicated the disease.
Encounter Alexander Fleming. Find out how he felt about the fungus Penicillium notatum.
He was awarded the Nobel Prize in Physiology and Medicine. He worked with the new science of bacteriology and discovered that specific bacteria or organisms cause specific diseases.
Typhoid Mary was a carrier of the deadly disease of typhoid but was never sick herself. Her real name was Mary Mallon, and she was considered such a threat to public health in New York City in the early 1900s that she was quarantined on North Brother Island in the East River for 23 years.
The Internet's largest and most authoritative site for prions, mad cow disease (bovine spongiform encephalopathy or BSE), scrapie, Creutzfeldt-Jakob Disease (CJD and nvCJD), kuru,and chronic wasting disease (CWD). Over 6966 articles, updated twice weekly.
He was a 19th century sanitary reformer. He was instrumental in helping to get a law passed called the UK Sanitary Act of 1866 that helped improve water systems, waste disposal, and housing standards.
Meet some sick cows and learn about the cycle of this disease, how it is spread, who is at risk, how to keep yourself safe, and the impact that Bovine Spongiform Encephalopathy is having on the economy of affected countries.
An introduction to the most deadly human plague of the twentieth century: Spanish Influenza. Contains links to swine flu and bird flu resources and the science thriller Ninth Day of Creation, in which the microbe is resurrected by an ambitious San Diego biotechnology company.
An antibiotic (the Greek word anti which means against and the Greek word bio which means life) is any substance produced by a microorganism which can kill or inhibit the growth of a different microorganism. Find out how antibiotics can help stop the cycle of disease.
What is E.coli? What is mad cow disease? What is a virus? What is an antibody? Find out from this germy site.
Learn more about the flu. Influenza viruses are divided into three types, designated A, B, and C. These viruses are constantly changing which means that people are susceptible to getting the flu throughout their lives.
Learn which diseases are quarantine-able in today's world. Historically, there were three types of quarantine used as early methods of fighting infection: isolating sick individuals, restricting freedom of movement during epidemics, and isolating healthy people who had been exposed to infectious disease.
Learn about what has been called the most devastating outbreak of disease in the history of the world. The influenza pandemic in 1918 and 1919 killed between 20 and 40 million people.
Discover the relationship that diseases spread by insects have had on history. Entomologists (scientists who study insects) have long understood the impact that insects and disease have had on history.
Find out how diphtheria, ringworm, typhoid fever, leprosy, and hantavirus are spread.
Plague is not an eradicated disease. The United States averages about 13 cases per year. There are three forms of plague: Bubonic, Septicemic, and Pneumonic.
Figure out how the cycles of the weather affect the cycles of ticks which then affects the spread of Rocky Mountain Spotted Fever.
Learn about the disease that was called consumption for much of its history. Tuberculosis appears in Greek literature as far back as 450 B.C.
Learn which immunizations you need to protect against infectious diseases.
Find out how penicillin and other antibiotics prevent the cell wall of a bacterial cell from forming and, thereby, help to inhibit the spread of contagious disease.
Check out the World Health Organization to learn about the cycles of malaria infection and other worldwide diseases.
Discover how smallpox has affected humanity over the past 3000 years. This disease would sweep across continents and kill 30% of all who were infected with it.
