APHA Voices posted a Q&A blog article featuring the director of the Division of Vector-Borne Diseases at CDC's National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), Dr. Lyle Petersen. He describes some lessons learned from Zika this past year, while touching on what is still unknown and what needs to be learned. He ends by highlighting how to better prepare for future vector-borne threats.
The CDC Weekly Mortality and Morbidity Report describes 13 infants born in Brazil with laboratory evidence of Zika virus infection during October 2015–January 2016. While these infants had the absence of microcephaly at birth, they were later found to have brain abnormalities associated with congenital Zika syndrome. These brain abnormalities include decreased brain volume, ventriculomegaly, subcortical calcifications, and cortical malformations. Head growth was documented to have decelerated as early as five months of age among all of the infants and 11 of the 13 had microcephaly.
The CDC has updated and combined its interim guidance for persons with possible Zika virus exposure who are planning to conceive and its interim guidance on preventing Zika virus transmission through sexual contact as of Septmeber 2016.
