Zika Case Counts in the US—from CDC

Zika virus disease is now a nationally notifiable condition. Cases are reported to CDC by state, territorial, and local health departments using standard case definitions. This webpage contains provisional data reported to ArboNET for January 1, 2015 – April 12, 2017.  

US States

·         5,234 Zika virus disease cases reported

o    4,935 cases in travelers returning from affected areas

o    223 cases acquired through presumed local mosquito-borne transmission in Florida (N=217) and Texas (N=6)

o    76 cases acquired through other routes, including sexual transmission (N=46), congenital infection (N=28), laboratory transmission (N=1), and person-to-person through an unknown route (N=1)

US Territories

·         36,526 Zika virus disease cases reported

o    143 cases in travelers returning from affected areas

o    36,383 cases acquired through presumed local mosquito-borne transmission

o    0 cases acquired through other routes*

*Sexually transmitted cases are not reported for US territories because with local transmission of Zika virus it is not possible to determine whether infection occurred due to mosquito-borne or sexual transmission.

There is no vaccine to protect against West Nile virus, and anti-viral medicines are ineffective.  The best way to keep from being infected is to avoid getting bitten by mosquitoes.  Current preventive measures in South Lake Mosquito Abatement District include frequent and on-going surveillance, larvaciding and adultciding.

At the present time we do not have Zika virus in northeastern Illinois


Update on Zika Virus–Associated Birth Defects 

• In 2016, a total of 1,297 pregnancies with possible recent Zika virus infection were reported to the U.S. Zika Pregnancy Registry from 44 states.

• Approximately one in 10 pregnancies with laboratory-confirmed Zika virus infection resulted in a fetus or infant with Zika virus–associated birth defects.

• The proportion of fetuses and infants with Zika virus–associated birth defects was highest among those with first trimester Zika virus infections.

• Only 25% of infants from pregnancies with possible recent Zika virus infection reported receiving postnatal neuroimaging.

• Identification and follow-up care of infants born to mothers with laboratory evidence of possible recent Zika virus infection during pregnancy and infants with congenital Zika virus infection can ensure that appropriate intervention services are available to affected infants.
