Mask-wearing and social distancing became political statements. Conspiracy theories spread wildly. And governments failed to conduct the routine testing and contact-tracing needed to control the disease. Too often, investigators found, national leaders made health decisions with an eye on keeping their economies afloat, though they did not single out many nations for criticism.
That proved to be a false choice. That conclusion is an implicit rebuke of countries like the United States, where President Trump demanded that the country stay open for business.
That figure is now over 23 million, and the country leads the world with nearly , deaths. The Covid pandemic has already forced public health officials to reconsider some of their assumptions. It had long been accepted, for example, that travel bans did more harm than good by delaying medical help and unfairly punishing countries. The World Health Organization used this "eradication escalation" technique elsewhere with such success that global eradication of smallpox was achieved by CDC also achieved notable success at home tracking new and mysterious disease outbreaks.
In the mids and early s, it found the cause of Legionnaires disease and toxic-shock syndrome. Although CDC succeeded more often than it failed, it did not escape criticism.
For example, television and press reports about the Tuskegee study on long-term effects of untreated syphilis in black men created a storm of protest in Although the effectiveness of penicillin as a therapy for syphilis had been established during the late s, participants in this study remained untreated until the study was brought to public attention. CDC also was criticized because of the effort to vaccinate the U.
When some vaccinees developed Guillain-Barre syndrome, the campaign was stopped immediately; the epidemic never occurred. As the scope of CDC's activities expanded far beyond communicable diseases, its name had to be changed. In it became the Center for Disease Control, and in , after extensive reorganization, Center became Centers.
The words "and Prevention" were added in , but, by law, the well-known three-letter acronym was retained. Fifty years ago CDC's agenda was noncontroversial hardly anyone objected to the pursuit of germs , and Atlanta was a backwater. Etheridge, Ph. Berkeley, California: University of California Press, The most notable of the agency's many achievements in the following 10 years was its role in global smallpox eradication, a program that finally succeeded because of the application of scientific principles of surveillance to a complex problem.
In the realm of infectious diseases, CDC maintained its preeminence, identifying the Ebola virus and the sexual transmission of hepatitis B, and isolating the hepatitis C virus and the bacterium causing Legionnaires disease.
The Study of the Effectiveness of Nosocomial Infection Control SENIC was the most expensive study the agency had ever undertaken and proved for the first time the effectiveness of recommended infection-control practices. Other studies included identification of the association of Reye syndrome with aspirin use, the relation between liver cancer and occupational exposure to vinyl chloride, and the harmful effects of the popular liquid protein diet. The s institutionalized what is considered to be a critically important scientific activity at CDC -- the collaboration of laboratorians and epidemiologists.
The decade began with the national epidemic of toxic-shock syndrome, documentation of the association with a particular brand of tampons, and the subsequent withdrawal of that brand from the market.
The fire was evidently started by a prisoner awaiting execution in the nearby prison. The fire destroyed the prison and the statehouse, though many of the public records were saved. In , the government and capital were moved from Jamestown to Middle Plantation, renamed Williamsburg. People continued to live on Jamestown Island and owned farm lands, but it ceased to be a town.
Today, Jamestown Island is a historic site, though there is still a private residence on the island. It is preserved by the National Park Service and Preservation Virginia for visitors to learn about the importance of Jamestown and what was born out of its being the first permanent English settlement in North America.

By , park visitation reached one million people per year. Neglected during World War II, the infrastructure in national parks continued to deteriorate as visitation soared afterward, leading to widespread complaints.
Although also designed to increase education programs and employee housing, Mission 66 focused mainly on visitor facilities and roads. Trained as an architect, Wirth encouraged the use of modern materials and prefabricated components to quickly and inexpensively construct low-maintenance buildings.
Work in Yellowstone included the development of Canyon Village. Aging visitor use facilities were replaced with modernistic visitor use facilities designed to reflect American attitudes of the s. Visitor services were arranged around a large parking plaza with small cabins a short distance away. Human occupation of this area seems to follow environmental changes of the last 15, years. Many tribes have a traditional connection to this region and its resources. In the late s, fur traders traveled the Yellowstone River in search of Native Americans with whom to trade.
Formal expeditions mapped and explored the area, leading to the nation's understanding of the region. The human history of the Yellowstone region goes back more than 11, years. Managing the national park has evolved over time and dealt with some complex issues. Explore This Park. Info Alerts Maps Calendar Reserve. Alerts In Effect Dismiss. Dismiss View all alerts.
