纽约市报道 2 人类感染西尼罗河病毒病例,该市感染蚊子数量创历史新高

Two human cases of West Nile virus have been reported in New York as the virus has been detected in a record number of mosquitoes in the city, 卫生官员周二表示.

Across the city’s five boroughs, 1,068 mosquito pools have tested positive for the virus, according to the New York City Department of Health and Mental Hygiene. The city recorded 779 positive pools at the same time last year.
The two human cases were reported in Brooklyn and Queens, the health department said in a 声明.
    The West Nile virus is most commonly spread to people through the bite of an infected mosquito, 根据 US Centers for Diseases Control and Prevention. Those cases happen during mosquito season, which starts in the summer and continues through fall, the CDC said.
      We are in the height of West Nile virus season, but there are things you can do to decrease your risk of being bitten,” New York City Health Commissioner Dr. Ashwin Vasan said.
        Using an insect repellent and wearing long sleeves and pants, especially when outside during late and early hours, may help prevent the risk of getting bit, Vasan explained.
        There is no vaccine for the virus, so preventative measures are the most effective way to avoid infection.
          Symptoms of West Nile infection include fatigue, 发烧, headache, body aches and rash. 然而, 80% of infected people do not display any symptoms, 根据 CDC.
          In rare cases, the virus can also be spread through blood transfusions, organ transplants, exposure in a lab setting or from mother to infant.
            少于 1% of infected people develop a serious neuroinvasive illness, such as encephalitis (inflammation of the brain) or meningitis (inflammation of the protective membranes covering the brain and spinal cord), 根据 CDC.
            As of August 9, 总共 54 human cases of the virus disease have been reported to the CDC 今年. 去年, 2,695 human cases were reported to the agency.
