Addressing Pregnancy Related Concerns During Ebola Outbreaks

Highlights:

  • Ebola virus disease (EVD) caused by the Ebola virus is a potentially life-threatening infection and there have been several outbreaks, the largest recorded one that occurred in West Africa between 2014-16 resulting in over 28,000 cases and 11,000 deaths
  • Current knowledge on Ebola virus disease has led to better understanding of managing individual cases, diagnosis and infection control in hospitals, the role of vaccinations as well as psychosocial care. However, knowledge about Ebola in pregnancy still remains painfully low
  • More studies that include pregnant women are needed to gain a better understanding on how Ebola affects pregnancy so that more effective control measures to prevent and control Ebola in the pregnant woman and her baby can be evolved in future

Ebola virus disease has been a major threat to public health with numerous outbreaks since it was first discovered in 1976 in Central Africa resulting in many deaths to date. In fact, the most recent Ebola virus outbreak has been reported on August 1, 2018, the 10th in the Democratic Republic of Congo alone since 1976. Until November, 341 cases and 215 deaths have been reported, making this the third-largest Ebola outbreak in the world to date.


Recent data show that although knowledge and understanding about Ebola virus disease have improved, issues related to EVD in pregnancy have been largely overlooked.

‘Currently, knowledge on how Ebola virus affects pregnancy is limited. More studies and data are essential to understand this and to be able to develop effective evidence-based recommendations regarding care of the pregnant woman during Ebola outbreaks’

Issues of Concern Due to Ebola Virus Disease in Pregnancy

Available data on Ebola in pregnancy, although low show sufficient reason to be concerned about and to institute remedial measures

  • Women found to have higher rates of infection compared to men. The reason may be increased vulnerability or getting the infection while caring for affected family members
  • Some studies suggest the death rate in pregnant women with Ebola may be as high as 90% although more data is needed to validate this observation
  • In almost all EVD cases in pregnancy the developing fetus in the womb is affected resulting in miscarriage, still birth or neonatal death
  • Following an EVD outbreak, pregnant women are at increased risk of mortality and morbidity due poor general health and increased susceptibility to infections in general and lack of antenatal care due to diversion of health personnel to attend to the outbreak, closure of hospitals to control spread of infection and reluctance to go to hospital due to lack of trust in the healthcare system
  • Obstetrical units may be a major source of EVD transmission due to high risks associated with contact with blood and body fluids during childbirth as well as delayed diagnosis further enhancing transmission. Interestingly, in the latest outbreak in the Congo Republic, the transmission of infection within the hospital was traced to an infected woman who underwent cesarean section delivery

Gaps in Existing System and Potential Ways to Overcome

Given the above-mentioned issues of concern related to EVD in pregnancy, the existing gaps in the system must be identified and plugged to ensure effective care of the pregnant woman resulting in healthy mother and baby.

  • Recently issued recommendations by an expert panel for supportive care of cases admitted to Ebola treatment units did not include care of pregnant women

To overcome this flaw, clinical experts in critical care during pregnancy in general and those with experience in treating critically ill patients with EVD should be impanelled to review available data and develop appropriate guidelines.

  • Although, vaccination has been shown to be key in Ebola preventive and control measures, pregnant women have largely been left out of vaccination trials due to fear of including them and very little data is available on the effectiveness of vaccination in pregnancy. In fact the WHO has recommended against vaccination of pregnant women

Some experimental trials have enrolled pregnant women, and demonstrated that pregnant women can be safely included in clinical trials during an outbreak. The authors of these trials believe pregnant women also should be given the opportunity to be a part of experimental Ebola vaccines and treatment studies, after explaining of the potential risks and benefits so that evidence-based data becomes available for future consideration.

  • Limited data are currently available on the care of pregnant women who had previously been infected especially since prolonged persistence of the virus in the body has been documented

More studies on EVD during pregnancy, the persistence of the virus and the effects of Ebola infection during delivery and postpartum period have to be undertaken to improve the care of pregnant women with Ebola. At the very least, recording of pregnancy status and self-reporting of pregnancy should be encouraged in all women of reproductive age during an Ebola outbreak.

  • More research is needed into the societal barriers that prevent EVD survivors from resuming their normal lives. Such barriers include emotional stress, underlying physical and mental health issues, and gender based discrimination, all of which are amplified in women, especially pregnant women
  • Contraception and family planning service in a region already burdened by frequent Ebola outbreaks may not be sufficient, resulting in unplanned pregnancies and consequent risk

The public should be educated on family planning and contraception and these services should be strengthened to reduce the potential hazards of unplanned pregnancy in the context of EVD.

Conclusion

Current reports suggest that the available health care system remains unprepared to care for the pregnant woman with Ebola. To change this, existing maternal and obstetric health services should be strengthened and more data gathered to ensure effective control and prevention of Ebola in pregnancy.
