In 1980, the World Health Organization (WHO) officially declared that smallpox had been eradicated. In 1986, WHO's international Ad Hoc Committee on Orthopox Virus Infections unanimously recommended destruction of the two remaining official stocks of variola virus, one at the Centers for Disease Control and Prevention and the other at the VECTOR laboratory in Siberia. In June 1999, WHO decided to delay the destruction of these stocks. Informing that decision was Assessment of Future Scientific Needs for Variola Virus, which examines: Whether the sequenced variola genome, vaccinia, and monkey pox virus are adequate for future research or whether the live variola virus itself is needed to assist in the development of antiviral therapies. What further benefits, if any, would likely be gained through the use of variola in research and development efforts related to agent detection, diagnosis, prevention, and treatment. What unique potential benefits, if any, the study of variola would have in increasing our fundamental understanding of the biology, host-agent interactions, pathogenesis, and immune mechanisms of viral diseases.

“The bard of biological weapons captures the drama of the front lines.”—Richard Danzig, former secretary of the navy The first major bioterror event in the United States-the anthrax attacks in October 2001-was a clarion call for scientists who work with “hot” agents to find ways of protecting civilian populations against biological weapons. In The Demon in the Freezer, his first nonfiction book since The Hot Zone, a #1 New York Times bestseller, Richard Preston takes us into the heart of Usamriid, the United States Army Medical Research Institute of Infectious Diseases at Fort Detrick, Maryland, once the headquarters of the U.S. biological weapons program and now the epicenter of national biodefense. Peter Jahrling, the top scientist at Usamriid, a wry virologist who cut his teeth on Ebola, one of the world’s most lethal emerging viruses, has ORCON security clearance that gives him access to top secret information on bioweapons. His most urgent priority is to develop a drug that will take on smallpox-and win. Eradicated from the planet in 1979 in one of the great triumphs of modern science, the smallpox virus now resides, officially, in only two high-security freezers-at the Centers for Disease Control in Atlanta and in Siberia, at a Russian virology institute called Vector. But the demon in the freezer has been set loose. It is almost certain that illegal stocks are in the possession of hostile states, including Iraq and North Korea. Jahrling is haunted by the thought that biologists in secret labs are using genetic engineering to create a new superpox virus, a smallpox resistant to all vaccines. Usamriid went into a state of Delta Alert on September 11 and activated its emergency response teams when the first anthrax letters were opened in New York and Washington, D.C. Preston reports, in unprecedented detail, on the government’ s response to the attacks and takes us into the ongoing FBI investigation. His story is based on interviews with top-level FBI agents and with Dr. Steven Hatfill. Jahrling is leading a team of scientists doing controversial experiments with live smallpox virus at CDC. Preston takes us into the lab where Jahrling is reawakening smallpox and explains, with cool and devastating precision, what may be at stake if his last bold experiment fails.

The story of the rise and fall of smallpox, one of the most savage killers in the history of mankind, and the only disease ever to be successfully exterminated (30 years ago next year) by a public health campaign.

A horrifying epidemic of smallpox was sweeping across the Americas when the War of Independence began, and yet little is known about it. Fenn reveals how deeply "variola" affected the outcome of the war in every colony and the lives of everyone in North America. Illustrations.

At the World Health Assembly in May 1980, the World Health Organization declared the world free of smallpox. Smallpox vaccination of civilians is now indicated only for laboratory workers directly involved with smallpox or closely related orthopox viruses. However recent questions raised by the terrorist attacks in fall 2001 have renewed concerns about possible outbreaks of smallpox resulting from its use as a biological weapon. In June 2002, the Institute of Medicine convened a public conference to discuss the scientific, clinical, procedural, and administrative aspects of various immunization strategies. Scientific and Policy Considerations in Developing Smallpox Vaccination Options summarizes the presentations and discussions from this workshop.

THE ESSENTIAL WORK IN TRAVEL MEDICINE -- NOW COMPLETELY UPDATED FOR 2018 As unprecedented numbers of travelers cross international borders each day, the need for up-to-date, practical information about the health challenges posed by travel has never been greater. For both international travelers and the health professionals who care for them, the CDC Yellow Book 2018: Health Information for International Travel is the definitive guide to staying safe and healthy anywhere in the world. The fully revised and updated 2018 edition codifies the U.S. government's most current health guidelines and information for international travelers, including pretravel vaccine recommendations, destination-specific health advice, and easy-to-reference maps, tables, and charts. The 2018 Yellow Book also addresses the needs of specific types of travelers, with dedicated sections on: · Precautions for pregnant travelers, immunocompromised travelers, and travelers with disabilities · Special considerations for newly arrived adoptees, immigrants, and refugees · Practical tips for last-minute or resource-limited travelers · Advice for air crews, humanitarian workers, missionaries, and others who provide care and support overseas Authored by a team of the world's most esteemed travel medicine experts, the Yellow Book is an essential resource for travelers -- and the clinicians overseeing their care -- at home and abroad.

The seventh edition of the Canadian Immunization Guide was developed by the National Advisory Committee on Immunization (NACI), with the support ofthe Immunization and Respiratory Infections Division, Public Health Agency of Canada, to provide updated information and recommendations on the use of vaccines in Canada. The Public Health Agency of Canada conducted a survey in 2004, which confi rmed that the Canadian Immunization Guide is a very useful and reliable resource of information on immunization.
