Emerging infectious disease outbreaks: old lessons and new challenges for obstetrician-gynecologists.

OBJECTIVE: The purpose of this study was to summarize 3 recent high-profile infectious disease threats that have affected the United States: severe acute respiratory syndrome, West Nile virus, and anthrax. STUDY DESIGN: A systematic review was conducted with the use of Medline searches, searches of the Centers for Disease Control and Prevention website, and review by experts at the Centers for Disease Control and Prevention. RESULTS: The 3 emerging infectious diseases pose very different threats: Severe acute respiratory syndrome is a newly identified pathogen that caused an international pandemic; the West Nile virus investigation involved an old pathogen that was identified in a new location; and the anthrax attacks involved the intentional introduction of a pathogen. CONCLUSION: All 3 outbreaks highlight the importance of obstetrician-gynecologists keeping current with new information as it emerges. In this global environment, it is likely that novel disease threats will continue to emerge in the United States.

Emerging infections and pregnancy: West Nile virus, monkeypox, severe acute respiratory syndrome, and bioterrorism.

As new infectious diseases, such as West Nile virus, monkeypox, and severe acute respiratory syndrome (SARS) are recognized in the United States, there are critical questions about how these infectious diseases will affect pregnant women and their infants. In addition, the implications of bioterrorist attacks for exposed pregnant women need to be considered. In this article, the authors address the following questions for a number of infectious disease threats: (1) does pregnancy affect the clinical course of these novel infectious diseases?, (2) what are the implications for prophylaxis and treatment of exposed or infected pregnant women?, and (3) are these novel infectious diseases transmitted during pregnancy, labor and delivery, or breastfeeding?

The role of the obstetrician-gynecologist in emerging infectious diseases: monkeypox and pregnancy.

Early in June 2003, the Centers for Disease Control and Prevention (CDC) announced yet another unique infectious disease outbreak, the first evidence of community-acquired monkeypox in the United States. By July 8, 2003, a total of 71 cases had been reported to CDC from 6 states. When emerging infectious diseases are reported in the United States, particularly when these reports receive widespread media attention, obstetrician-gynecologists may be called upon to rapidly respond to queries from their patients and to address certain infectious disease risks within their clinical practices. In addition, obstetrician-gynecologists may have specific concerns about the implications for an infectious disease outbreak, such as monkeypox, for pregnant women. Therefore, it is important that obstetrician-gynecologists know how to gather up-to-date and accurate information about infectious disease outbreaks and that they be familiar with the public health response system for responding to such outbreaks.

SARS surveillance during emergency public health response, United States, March-July 2003.

In response to the emergence of severe acute respiratory syndrome (SARS), the United States established national surveillance using a sensitive case definition incorporating clinical, epidemiologic, and laboratory criteria. Of 1,460 unexplained respiratory illnesses reported by state and local health departments to the Centers for Disease Control and Prevention from March 17 to July 30, 2003, a total of 398 (27%) met clinical and epidemiologic SARS case criteria. Of these, 72 (18%) were probable cases with radiographic evidence of pneumonia. Eight (2%) were laboratory-confirmed SARS-coronavirus (SARS-CoV) infections, 206 (52%) were SARS-CoV negative, and 184 (46%) had undetermined SARS-CoV status because of missing convalescent-phase serum specimens. Thirty-one percent (124/398) of case-patients were hospitalized; none died. Travel was the most common epidemiologic link (329/398, 83%), and mainland China was the affected area most commonly visited. One case of possible household transmission was reported, and no laboratory-confirmed infections occurred among healthcare workers. Successes and limitations of this emergency surveillance can guide preparations for future outbreaks of SARS or respiratory diseases of unknown etiology.

Investigation of Kawasaki syndrome risk factors in Colorado.

Risk factors for Kawasaki syndrome (KS) were evaluated through a case-control study during an investigation of a KS cluster in Denver, CO. KS was associated with a humidifier in the child's room (odds ratio, 7.3; 95% confidence interval, 1.8 to 29.3) and possibly with an antecedent respiratory illness. The use of humidifiers should be further investigated as part of future studies of KS.

Call-tracking data and the public health response to bioterrorism-related anthrax.

After public notification of confirmed cases of bioterrorism-related anthrax, the Centers for Disease Control and Prevention's Emergency Operations Center responded to 11,063 bioterrorism-related telephone calls from October 8 to November 11, 2001. Most calls were inquiries from the public about anthrax vaccines (58.4%), requests for general information on bioterrorism prevention (14.8%), and use of personal protective equipment (12.0%); 882 telephone calls (8.0%) were referred to the state liaison team for follow-up investigation. Of these, 226 (25.6%) included reports of either illness clinically confirmed to be compatible with anthrax or direct exposure to an environment known to be contaminated with Bacillus anthracis. The remaining 656 (74.4%) included no confirmed illness but reported exposures to "suspicious" packages or substances or the receipt of mail through a contaminated facility. Emergency response staff must handle high call volumes following suspected or actual bioterrorist attacks. Standardized health communication protocols that address contact with unknown substances, handling of suspicious mail, and clinical evaluation of suspected cases would allow more efficient follow-up investigations of clinically compatible cases in high-risk groups.

Epidemiologic clues to bioterrorism.

Public health investigators have successfully carried out epidemiologic investigations of outbreaks of disease for many years. By far the majority of these outbreaks have occurred naturally. With the recent illnesses resulting from deliberate dissemination of B. anthracis on an unsuspecting population, public health investigation of diseases must now include consideration of bioterrorism as a potential cause of outbreaks of disease. The features of naturally occurring outbreaks have a certain amount of predictability in terms of consistency with previous occurrences, or at least biological plausibility. However, with a deliberately introduced outbreak or infection among a population, this predictability is minimized. In this paper, the authors propose some epidemiologic clues that highlight features of outbreaks that may be suggestive of bioterrorism. They also describe briefly the general process of involvement of agencies at various levels of government, public health and non-public health, depending on the extent of an outbreak or level of suspicion.
