Zika Cases in the United States
In addition to providing some funds, and in an effort to “increase the public’s trust that [they] are providing facts [the public] can use to make informed decisions” in compliance with item 11 under the Clear Communication Index
, the CDC published a bulletin
explaining the uncertainties surrounding Zika.
On their website, the CDC has made available two maps
of the United States depicting the estimated range of Aedes aegypti
and Aedes albopictus
mosquitos (the two vectors which can carry the Zika virus) within the 50 states. According to the bulletin, the maps show areas where the mosquitos are either currently found or have been found in the past. However, the maps are “not
meant to represent risk of spread of disease,” nor do they imply that the mosquitos in those areas are infected with the Zika virus.
Updates on Zika in Pregnancy
In terms of the risk of Zika in pregnant women and their fetuses, the CDC has clarified the following: women can either be infected through the bite of an infected mosquito, or through (several forms
of) sexual contact with an infected male. However, whether the mode of infection affects the risks associated with Zika or not is yet to be determined.
The CDC confirms that a fetus can be infected during pregnancy or at the time of delivery. Nonetheless, there are several factors which are still unclear. For example, the probability of a woman (or any individual) to become infected upon exposure to the virus is still uncertain, as is how the virus will affect the mother, her pregnancy, and her unborn child (if at all). Not only this, but the probability of an infected fetus to develop neurological or other birth defects is still to be determined, as well. Although some healthcare providers can agree that the first trimester and the beginning of the second trimester of pregnancy are likely the time during which a Zika infection is to cause the most harm
to a fetus, it is not certain.
Recent Zika Research
In an effort to better understand the effects of a Zika infection, the National Institute of Health’s (NIH) Eunice Kennedy Shriver
National Institute of Child Health and Human Development (NICHD) will fund a research initiative
that aims to study viral exposure in athletes, coaches, and staff from the US Olympic Committee (USOC) who will be attending the 2016 games in Rio de Janeiro, Brazil, where there is active Zika transmission.
With this study, researchers hope to better understand not only the dynamics of Zika, but also the risk factors for infection, the reproductive outcomes of those participants infected with the virus, as well as where and for how long the virus remains in the body. Carrie L. Byington, MD, from the University of Utah in Salt Lake City, UT will lead the study.
In order to overcome the fear that Zika has instilled in healthcare providers and families alike, the threats posed by the effects of Zika should not be taken lightly. Zika vaccine developments are finally underway after much stalling
, as are research efforts. However, in order for states to better protect their citizens from initial infection, government funding is needed.
*According to the press release, “WRAIR, the National Institute of Allergy and Infectious Diseases (NIAID)–part of the U.S. National Institutes of Health (NIH), and the Biomedical Advanced Research and Development Authority (BARDA)–part of the Health & Human Services (HHS) Office of the Assistant Secretary of Preparedness and Response–have been coordinating pre-clinical development of the candidate encouraged by new, pre-clinical research conducted by WRAIR and the Beth Israel Deaconess Medical Center. NIAID will sponsor a series of phase 1 ZPIV trials while the technology transfer process is occurring.”
