ACOG Committee Opinion number 268, February 2002. Management of asymptomatic pregnant or lactating women exposed to anthrax. American College of Obstetricians and Gynecologists.

Anthrax infections are diagnosed by isolating Bacillus anthracis from body fluids or by measuring specific antibodies in the blood of persons suspected to have the disease. It is recommended that asymptomatic pregnant and lactating women who have been exposed to a confirmed environmental contamination or a high-risk source as determined by the local Department of Health (not the women's health care provider) receive prophylactic treatment. A variety of antimicrobial regimens are available. Although some of these drugs may present risks to the developing fetus, these risks are clearly outweighed by the potential morbidity and mortality from anthrax. Guidelines for prophylactic treatment of anthrax and treatment of suspected active cases of anthrax are changing continually, and the Centers for Disease Control and Prevention web site should be consulted for the latest recommendations.
