Early Release

  • Guillain-Barré Syndrome During Ongoing Zika Virus Transmission — Puerto Rico, January 1–July 31, 2016

    August 26, 2016
    Countries affected by Zika virus have reported increased cases of Guillain-Barré syndrome (GBS), an uncommon autoimmune disorder. In February 2016, the Puerto Rico Department of Health implemented the GBS Passive Surveillance System. Fifty-six suspected GBS cases with onset of neurologic signs were identified during January 1–July 31, 2016.

  • Likely Sexual Transmission of Zika Virus from a Man with No Symptoms of Infection — Maryland, 2016

    August 26, 2016
    A man in Maryland, who had recently traveled to the Dominican Republic, likely transmitted Zika virus to a female sex partner via intercourse without a condom. The man reported no symptoms consistent with Zika virus infection nor any other symptoms of illness, although serologic testing on specimens collected 29 days after his return was positive to Zika immunoglobulin M antibodies.  Based on the report’s findings, it might be appropriate to consider persons who have condomless sex with partners returning from areas with ongoing Zika virus transmission as exposed to Zika virus, regardless of whether the returning traveler reports symptoms of Zika virus infection.

    In 2015, the Drug Enforcement Administration and CDC issued nationwide alerts identifying illicitly manufactured fentanyl as a threat. During 2013–2014, the number of drug products obtained by law enforcement that tested positive for fentanyl (fentanyl submissions) increased by 426%, and synthetic opioid–involved overdose deaths (excluding methadone) increased by 79% in the United States.

Recommendations and Reports

  • Prevention and Control of Seasonal Influenza with Vaccines: Recommendations of the Advisory Committee on Immunization Practices — United States, 2016–17 Influenza Season

    August 26, 2016
    This report updates the 2015–16 recommendations of the Advisory Committee on Immunization Practices (ACIP) regarding the use of seasonal influenza. Routine annual influenza vaccination is recommended for all persons aged ≥6 months. For the 2016–17 influenza season, inactivated influenza vaccines (IIVs) will be available in both trivalent (IIV3) and quadrivalent (IIV4) formulations. Recombinant influenza vaccine (RIV) will be available in a trivalent formulation (RIV3). In light of concerns regarding poor effectiveness against influenza A(H1N1)pdm09 in the United States during the 2013–14 and 2015–16 seasons, for the 2016–17 season, ACIP makes the interim recommendation that live attenuated influenza vaccine (LAIV4) should not be used. Vaccine virus strains included in the 2016–17 U.S. trivalent influenza vaccines will be an A/California/7/2009 (H1N1)–like virus, an A/Hong Kong/4801/2014 (H3N2)–like virus, and a B/Brisbane/60/2008–like virus (Victoria lineage). Quadrivalent vaccines will include an additional influenza B virus strain, a B/Phuket/3073/2013–like virus (Yamagata lineage). These recommendations apply to all licensed influenza vaccines used within Food and Drug Administration–licensed indications, including those licensed after the publication date of this report. Updates and other information are available at CDC’s influenza website (http://www.cdc.gov/flu). Vaccination and health care providers should check CDC’s influenza website periodically for additional information.
