Centers for Disease Control and Prevention (CDC) researchers in collaboration with researchers from the United States and Brazil investigated the first series of infants with laboratory evidence of congenital Zika virus infection documented to have onset of microcephaly after birth.
The report, published today in CDC’s Morbidity and Mortality Weekly Report, describes 13 infants in Brazil with congenital Zika virus infection who did not have microcephaly at birth, but later experienced slowed head growth. Among these infants, 11 later developed microcephaly. Slowed head growth and microcephaly were accompanied by significant neurologic complications. Although microcephaly was not present at birth, the infants had other brain abnormalities consistent with congenital Zika syndrome.
The study reveals that among infants of mothers exposed to Zika virus during pregnancy, the absence of microcephaly at birth does not rule out congenital Zika virus infection or the presence of Zika-related brain abnormalities.
The findings highlight the importance of recent CDC guidance on initial and continuing medical and developmental evaluations of infants with possible congenital Zika virus infection and the importance of early neuroimaging for infants who were exposed to Zika virus prenatally.
CDC continues to recommend that pregnant women not travel to areas with Zika. If a pregnant woman travels to or lives in an area with active Zika virus transmission, she should talk with her healthcare provider and strictly follow steps to prevent mosquito bites and sexual transmission of Zika virus. Pregnant women with possible exposure to Zika virus should be tested for Zika infection even if they do not have symptoms. For more information, visit www.cdc.gov/zika/pregnancy/.
CDC continues to encourage women considering pregnancy and their partners in areas with active Zika transmission to talk to their healthcare providers about pregnancy planning so that they know the risks and the ways to reduce them.

How Contaminated Is Your Stretcher? The Hidden Risks on Hospital Wheels
July 3rd 2025Despite routine disinfection, hospital surfaces, such as stretchers, remain reservoirs for harmful microbes, according to several recent studies. From high-touch areas to damaged mattresses and the effectiveness of antimicrobial coatings, researchers continue to uncover persistent risks in environmental hygiene, highlighting the critical need for innovative, continuous disinfection strategies in health care settings.
Beyond the Surface: Rethinking Environmental Hygiene Validation at Exchange25
June 30th 2025Environmental hygiene is about more than just shiny surfaces. At Exchange25, infection prevention experts urged the field to look deeper, rethink blame, and validate cleaning efforts across the entire care environment, not just EVS tasks.
A Controversial Reboot: New Vaccine Panel Faces Scrutiny, Support, and Sharp Divides
June 26th 2025As the newly appointed Advisory Committee on Immunization Practices (ACIP) met for the first time under sweeping changes by HHS Secretary Robert F. Kennedy Jr, the national spotlight turned to the panel’s legitimacy, vaccine guidance, and whether science or ideology would steer public health policy in a polarized era.
