Recognizing the detrimental effects of poorly-designed, high-intensity LED lighting, the AMA encourages communities to minimize and control blue-rich environmental lighting by using the lowest emission of blue light possible to reduce glare.
The AMA recommends an intensity threshold for optimal LED lighting that minimizes blue-rich light.
On February 26, 2016, the Council of State and Territorial Epidemiologists (CSTE) approved interim case definitions for Zika virus disease and Zika virus congenital infection and added them to the list of nationally notifiable conditions (9).
Subsequent reports of Zika virus disease cases will include cases reported to Arbo NET, the national arboviral surveillance system, using the interim CSTE case definitions.
Zika virus disease should be considered in patients with acute onset of fever, rash, arthralgia, or conjunctivitis who traveled to areas with ongoing transmission or had unprotected sex with someone who traveled to those areas and developed compatible symptoms within 2 weeks of returning.
Zika virus is an emerging mosquito-borne flavivirus.
CHICAGO - Strong arguments exist for overhauling the lighting systems on U. roadways with light emitting diodes (LED), but conversions to improper LED technology can have adverse consequences. Discomfort and disability from intense, blue-rich LED lighting can decrease visual acuity and safety, resulting in concerns and creating a road hazard.
Zika virus is primarily transmitted to humans by Aedes aegypti mosquitoes (1). When occurring, clinical illness is generally mild and characterized by acute onset of fever, maculopapular rash, arthralgia, or nonpurulent conjunctivitis. Severe disease requiring hospitalization is uncommon, and deaths are rare.
Temporary deferral of blood donors with recent travel to Zika-affected areas also has been recommended to reduce the risk for transfusion-associated transmission (8).
The cases presented in this report have clinical findings similar to those of Zika virus disease cases previously reported from other countries.
During January 1, 2015–February 26, 2016, a total of 116 residents of 33 U. states and the District of Columbia had laboratory evidence of recent Zika virus infection based on testing performed at CDC.
Cases include one congenital infection and 115 persons who reported recent travel to areas with active Zika virus transmission (n = 110) or sexual contact with such a traveler (n = 5).
