Infectious Diseases in Pregnancy

  • Zika Virus Infection in Pregnancy
    Zika virus infection in humans appears to have changed in character while expanding in geographical range. Zika virus has now been clearly established as the cause of severe fetal malformations, particularly microcephaly. The risk of fetal injury appears to be greater when maternal infection occurs in the first trimester of pregnancy. Zika virus has now been established as the cause of Guillain-Barré syndrome (GBS) in adults. Although most cases of Zika virus infection are transmitted as the result of mosquito bites, patients can acquire the infection through sexual contact. Both male-to-female and female-to-male transmission have been documented. Currently, real-time reverse transcription polymerase chain reaction (rRT-PCR), immunoglobulin M (IgM), and plaque reduction neutralization (PRNT) tests are available to detect Zika infection, although each test has limitations. If a patient has had symptoms of Zika virus infection for less than 5 days, serum and urine should be obtained for rRT-PCR testing. If symptoms have been present for 5 to 14 days, urine should be tested by rRT-PCR because urine samples appear to remain positive for virus longer than serum samples do. Early-stage trials examine whether an experimental vaccine is safe and generates immune responses in vaccinated volunteers. A safe and effective, fully licensed Zika vaccine will likely not be available for several years.

  • Ebola Virus Disease and Pregnancy
    The review provides general background information on Ebola virus disease (EVD) and specifically addresses what is known about EVD in pregnancy and the implications for practicing obstetricians and gynecologists. Limited evidence suggests that pregnant women are at increased risk for severe illness and death when infected with Ebola virus, but there is no evidence to suggest that pregnant women are more susceptible to EVD. It is important that all health care providers are prepared to respond to ensure that Ebola virus transmission is contained. Specifically, U.S. health care providers, including obstetricians and gynecologists, should ask patients about recent travel to affected countries in West Africa, know the signs and symptoms of EVD, and know what to do if they have a patient with compatible illness. For all healthcare providers, infection-control procedures are recommended, including standard, contact, and droplet precautions. Pregnant women with EVD appear to be at an increased risk for spontaneous abortion and pregnancy-associated hemorrhage. Neonates born to mothers with EVD have not survived.

  • Preventing Mother-to-Child Human Immunodeficiency Virus Transmission
    Human immunodeficiency virus (HIV) is a scourge which continues to fatally wound the physical, cultural, social, economic, political, and spiritual health achievements, hopes and aspirations of individuals, families, communities and nations. This review describes the utility of antenatal surveillance for monitoring and evaluating prevention of mother-to-child HIV transmission programs in resource limited countries and generalized HIV epidemics. Population-based data sources regarding the incidence and morbidity that are associated with perinatal HIV infection are improving and indicate that prevention efforts have been enormously successful. There have been major advances with the prevention of mother-to-child HIV transmission, and this review summarizes the successes and current challenges and provides suggestions for future directions. Viewing preventing the mother-to-child transmission as a gateway to family-based HIV care and treatment will help strengthen ties between these programs. Site-specific interventions to increase the uptake of prevention of mother-to-child transmission programs based on experiences in sub-Saharan Africa are discussed. Lessons learned can apply to many resource-constrained settings.

  • Group B Streptococci Perinatal Infections: A Comprehensive Review
    Group B streptococci (GBS) emerged dramatically in the 1970s as the leading cause of neonatal infection and as an important cause of maternal uterine infection. In 2002, new national guidelines were released recommending: 1) solely a screen-based prevention strategy, 2) a new algorithm for patients with penicillin allergy, and 3) more specific practices in certain clinical scenarios. In the pre-prevention era, active surveillance for invasive neonatal GBS disease estimated that approximately 6,100 early-onset cases and 1,400 late-onset cases occurred annually in the United States.  The purpose of this document is to address clinical issues of group B streptococci (GBS) perinatal infection, implementation of new diagnostic techniques, management of preterm rupture of membranes, use of alternative antibiotic approaches, improvement of compliance, prevention of low birth-weight infants, emergence of resistant organisms and vaccine development.
