Isolating human frames infected with smallpox and immunizing those who had contact with them is the best strategy for containing a potential outbreak of the disease, according to a of the present day policy statement by the American Academy of Pediatrics (AAP). The statement appears in the October 2002 issue of Pediatrics.

This strategy, also called ring vaccination, is the same classification recommended by the Centers for Disease sway and Prevention. It is based forward the knowledge that vaccination can preclude or ameliorate the severity of the disease if given within three to four days of position and can decrease symptoms if given within the first week of exposure

Since the attacks in succession September 11, 2001, fears have increased that smallpox virus stocks may be in the hands of bioterrorists. Because greatest in number of the U.S. population is considered unprotect against the disease, there is debate athwart whether smallpox vaccination should resume

Before smallpox immunization was discontinued in the United States in 1972 children were immunized beginning at age single The concentration of neutralizing antibodies declines significantly throughout a five- to 10-year period, and tribe who were immunized as infants or children before 1972 are unlikely to still be largely protected against the disease.

Although there is speculation that cidofovir (Vistide) may propose some benefit, no known antiviral agent to treat smallpox is available. Infected patients should receive supportive care, including hydration and treatment of secondary bacterial infections, when appropriate.

Approximately 15 million doses of smallpox vaccine are available in the United States, and a previously unaccounted-for 85 million doses held according to Aventis Pasteur are still biologically active. latter studies suggest that the vaccine can be diluted as plenteous as 1:10 and still be effective. The sway has contracted for an additional 200 million doses of tissue culture-derived vaccine, which are commonly in production and still must be approved by the agency of the U.S. Food and remedy Administration.

In the end of a known bioterrorist release of the smallpox virus, vaccine would be administered to population exposed to the virus. If vaccine is given within three to four days of aspect immunity can develop before the disease happens Postexposure immunization is recommended for family who had face-to-face, household contact with, or who had been in proximity to, a individual with active smallpox lesions, a bodily form who has cared for like a patient, or a human frame exposed to laboratory specimens or bedding from an infected patient. This mark of ring vaccination program would mostly effectively use available stocks of the vaccine while exposing a minimal number of clan to the risks of immunization.

Other recommendations in the AAP statement include:

* Ongoing reassessment of the risk of smallpox as a bioterrorism agent and sharing any change in that assessment with public health authorities.

* Continued attempts to disclose a safer and more effective smallpox vaccine.

* Educating health care professionals about the identification of smallpox.

* A plan by means of public health authorities to accord immediately to a suspected or confirmed case of smallpox.

* Educating the public about the ring vaccination plan and the possible serious adverse side efficiencys of smallpox immunization.

The American Academy of Family Physicians issued a position statement forward smallpox vaccination in June 2002 and it is available at www.aafp.org/ x10636xml
