Childhood immunizations in the United States
Mumps is a contagious disease caused by the virus by the same name. Since most people in the United States have been vaccinated, mumps is now a rare disease in this country. Currently there are no specific treatments for mumps.
Mumps is spread person to person by droplets of saliva or mucus from the mouth, nose or throat of an infected person. This is done through coughing, sneezing, talking, and coming into contact with contaminate items. Transmission likely occurs before the salivary glands swell an up to 5 days after the swelling begins.
ACAM2000
Smallpox works in the following way:"Smallpox spreads from one person to another by infected saliva droplets. The incubation period is 7 to 17 days. The symptoms begin with severe headache, backache, and fever up to 40 °C, all beginning abruptly. Then a rash appears on the face and spreads, the spots become watery blisters containing pus that form scabs and leave pitted scars when they fall off. The infected person is contagious until the last smallpox scab has fallen off, although most of the transmission occurs in the first week. Most people with smallpox recover, but some do die and the risk depends on the strain of virus." In 1980, the World Health Organization certified that the naturally occurring smallpox disease was eradicated. According to the FDA, "Until ACAM2000 was licensed, Dryvax, manufactured by Wyeth Laboratories, Inc., was the only vaccine licensed by FDA. Routine vaccination of the American public was stopped in 1972 after the disease was eradicated from the United States. However, smallpox has the potential to be deliberately used as a weapon by terrorists. A large proportion of the population has no immunity and fatality rates could be higher than 25% if smallpox were to be released as a bioterrorist weapon."
