In addition, 16 new travel related cases were reported today, five in Miami-Dade, three in Palm Beach, two in Broward, two in Orange, one in Polk and three involving pregnant women.

The total travel associated Zika cases now stands at 558 and 78 cases involving pregnant women.

In related news, Brazilian researchers describe in a study published in the US Centers for Disease Control and Prevention (CDC) publication, Morbidity and Mortality Weekly Report (MMWRcongenital hearing loss associated with Zika virus in infants born with microcephaly.

They summarize, congenital infection with Zika virus appears to be associated with sensorineural hearing loss. Among 70 children with microcephaly and laboratory evidence of congenital Zika virus infection, four of 69 (5.8%) were found to have sensorineural hearing loss without other potential cause.

Congenital infection with Zika virus should be considered a risk factor for hearing loss. Children with evidence of congenital Zika virus infection who have normal initial screening tests should receive regular follow-up, because onset of hearing loss associated with other congenital viral infections can be delayed and the loss can be progressive.
