Most had fever and rash; however, rates of conjunctivitis are lower than those seen in previous outbreaks (2).The majority (95%) of cases occurred in travelers to areas with ongoing mosquito-borne Zika virus transmission.Until more is known about the effects of Zika virus infection on the developing fetus, pregnant women should postpone travel to areas where Zika virus transmission is ongoing.Pregnant women who do travel to one of these areas should talk to their health care provider before traveling and strictly follow steps to avoid mosquito bites ( during travel. Zika virus is an emerging mosquito-borne flavivirus.Recent outbreaks of Zika virus disease in the Pacific Islands and the Region of the Americas have identified new modes of transmission and clinical manifestations, including adverse pregnancy outcomes. During January 1, 2015–February 26, 2016, a total of 116 residents of U. states and the District of Columbia had laboratory evidence of recent Zika virus infection based on testing performed at CDC, including 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).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.In response, physicians at the Annual Meeting of the American Medical Association (AMA) today adopted guidance for communities on selecting among LED lighting options to minimize potential harmful human and environmental effects. street lighting has been converted to solid state LED technology, with efforts underway to accelerate this conversion. In addition to its impact on drivers, blue-rich LED streetlights operate at a wavelength that most adversely suppresses melatonin during night.
Health care providers should educate patients, particularly pregnant women, about the risks for, and measures to prevent, infection with Zika virus and other mosquito-borne viruses.
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.
Excessive outdoor lighting disrupts many species that need a dark environment.
For instance, poorly designed LED lighting disorients some bird, insect, turtle and fish species, and U. national parks have adopted optimal lighting designs and practices that minimize the effects of light pollution on the environment.
