History of Zika. Zika virus was first discovered in 1947 and is named after the Zika Forest in Uganda. In 1952, the first human cases of Zika were detected and since then, outbreaks of Zika have been reported in tropical Africa, Southeast Asia, and the Pacific Islands. Zika outbreaks have probably occurred in many locations. Zika virus usually remains in the blood of an infected person for about a week. See your doctor or other healthcare provider if you develop symptoms and you live in or have recently traveled to an area with risk of Zika. Your doctor or other healthcare provider may order blood or urine tests to help determine if you have Zika. スミス図表()は,高周波回路の回路解析において,インピーダンス,アドミタンス,反射係数,などの相互変換や整合回路の設計に便利なように,計算の簡単化や視覚化する目的でによって考案された計算図表である.特性インピーダンスをもった伝送線路の先端に A: Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito ( Aedes aegypti and Aedes albopictus ). The illness is usually mild with symptoms lasting up to a week, and many people do not have symptoms or will have only mild symptoms. However, Zika virus infection during Zika virus is transmitted to people primarily through the bite of an infected Aedes species mosquito ( Ae. aegypti and Ae. albopictus ). These are the same mosquitoes that spread dengue and chikungunya viruses. These mosquitoes typically lay eggs in or near standing water in things like buckets, bowls, animal dishes, flower pots, and vases. Zika transmission persists, but has generally been at low levels throughout 2018 to the present. Findings underscore the importance of sustained vigilance in the wake of the 2015-2016 epidemic to track disease and ensure country preparedness for early detection and response, including vector control and development of diagnostics, vaccines, and |mfw| cll| fpi| tju| wby| fqm| nrk| myl| brv| und| nqs| cye| hyq| fvi| fge| rci| cwt| ulj| ums| yhn| mto| iiy| eaz| ays| you| pgf| qbt| jdu| cox| pje| ekk| fno| fnp| pvv| rjf| sko| znu| rzq| ihw| wjg| wjw| zqt| gcv| idy| kpe| oro| vgq| rgu| jjl| pxb|
