一 | 近日春暖花开、气温回升 你是不是计划着 带上装备踏青赏花 再来个踩水捉虾？ 近日，中国疾控中心接连发布提醒 注意防范血吸虫一年四季都有可能感染血吸虫病 4-10月是最容易感染的时间 春夏感染风险更大 外出玩水需谨慎 谨防感染血吸虫病 什么是血吸虫病？ 血吸虫病是由血吸虫寄生于人或者哺乳动物引起的具有传染性、地方性和自然疫源性的寄生虫病，是一种呈全球流行的被忽视的热带寄生虫病。 Israeli officials are planning to ask US President Joe Biden for his formal blessing to provide an Iron Beam laser-based air defense system to Gulf Arab states including the United Arab Emirates and possibly Saudi Arabia, Israel’s Channel 12 has reported.,The unsourced Hebrew-language report, cited by the Times of Israel, indicated the delivery of the system to the Gulf countries would assist with the US-led push to ramp up air defense cooperation between Tel Aviv and a loose regional coalition including Egypt, Jordan, Bahrain, the UAE, Saudi Arabia and Qatar.,The Jewish State does not have formal diplomatic relations with the latter two country, and Riyadh has repeatedly stated that it would not establish formal ties with Israel until the Palestinian question and the creation of a Palestinian state was settled.,On Sunday, the Wall Street Journal reported, citing US and Middle Eastern sources, that the Pentagon had organized a hush-hush meeting in Sharm El Sheikh, Egypt in March to discuss ways to improve air defense cooperation against Iranian ballistic missiles and drones. The meeting was said to have been chaired by then-US Central Command chief Frank McKenzie, and attended by top military commanders from Israel and the Arab countries who were invited.,Israeli Defense Minister Benny Gantz, who announced the formation of a regional anti-Iranian air defense alliance last week, appeared to signal the veracity of WSJ’s reporting on Monday, saying Israel was “building” a “wide partnership with additional countries in the region to ensure a secure, stable and prosperous Middle East,” and that “among other things, this also includes aerial defense.”,Israel Creating 'Middle East Air Defense Alliance' Under US' Wing, Defense Minister Says20 June, 11:03 GMT,“We will strengthen this, as a stable Middle East is an international, regional and Israeli interest of the highest order,” Gantz said.,Iran’s military also appeared to issue an indirect response to WSJ’s report, with Armed Forces Chief of Staff Mohammad Bagheri warning Monday that Tehran “will not tolerate” the threats posed by Israel and its cooperation with CENTCOM, and “will definitely react to them.”,Israel has long touted the purported advanced capabilities of its so-called ‘Iron Beam’ laser-based air defense system, a prototype of which was unveiled last year. Earlier this month, Prime Minister Naftali Bennett said the “game-changer” weapon would shift the balance in Israel’s favor, with the estimated $2 in electricity required per burst to intercept enemy rockets just a drop in the bucket compared to the tens of thousands of dollars a rocket might cost. Bennett expressed hope that the system would come online by 2023.,‘Iron Beam’: Israel’s New Laser Air Defence System ‘Will Bankrupt Enemies’, Bennett Says1 June, 11:44 GMT,Last week, Breaking Defense reported that Israel would ask Biden for more money Iron Beam’s development, on top of the $3.3 billion in annual US subsidies already received by the Israeli military and defense establishment. The outlet’s sources indicated that Israel will likely ask the US president to shell out about $300 million in additional cash.,“The relations between the US and Israel are solid. The issues that will be on the table during the visit are of utmost importance to both the US and Israel. I’m confident that the talks will be fruitful to both sides,” a senior defense source told the outlet.,During his trip to the Middle East next month, Biden is expected to tour an Israeli airbase and get a firsthand look at the prototype laser weapons being developed by Israeli defense giants Rafael and Elbit Systems.,Lasers for use against aircraft, missiles, drones, ships, and ground equipment have been on the drawing board of weapons developers since the Cold War, with engineers spending decades mulling over the prospects of replacing conventional missile and shell projectiles with the futuristic beam pulse. But energy-directed weapons have long faced what have previously been deemed unsolvable issues, such as the immense amounts of power required to operate them, as well as interaction between combat lasers and natural phenomena such as rain, fog, smog or dust, all of which dissipates their strength.,Last month, US weapons maker Raytheon reported that its own laser weapon, fitted aboard an Army Stryker vehicle, had successfully downed incoming mortar rounds in testing.,Raytheon Laser Weapon on Stryker Vehicle Succeeds at Shooting Down Incoming Mortar Shells19 May, 22:19 GMT。
二 | 我国流行的是由日本血吸虫感染引起的日本血吸虫病，属法定乙类传染病。如不及时治疗或未治愈，发展到晚期，肝脏等器官会受损，导致门静脉高压，出现肝脾肿大、腹水等症状，人会变得骨瘦如柴、肚大如鼓，因此也被称为“大肚子病”。 接触10秒即可感染 血吸虫是一种寄生于脊椎动物血管内的吸虫，又称裂体吸虫。能寄生于人体并致病的血吸虫主要有七种，即日本血吸虫、曼氏血吸虫、埃及血吸虫、间插血吸虫、湄公血吸虫、马来血吸虫和几内亚血吸虫。其中前三种分布最广泛、危害最严重。 血吸虫的发育分为虫卵、毛蚴、母胞蚴、子胞蚴、尾蚴、童虫及成虫共七个阶段，其中尾蚴是可以感染人体的阶段。
三 | 尾蚴在水中接触到人的体表后可侵入人体。有实验证明，宿主动物只要接触尾蚴10秒，就可被感染。 吸血虫不同于血吸虫 人们说的吸血虫，常常指的是水蛭，又称蚂蟥，是一种以吸血或食腐肉为生的体外寄生虫。其体长、扁平，略呈纺锤形，前后有两个吸盘可附着于人和动物体表。
四 | 水蛭生活在水田、河流、稻田、湖沼、沟渠和浅水污秽坑塘等处，在我国各地均有分布，种类很多。 如何预防血吸虫病？ 感染血吸虫的直接原因是接触了含有血吸虫尾蚴的水体（疫水）。因此，不接触可能含有血吸虫尾蚴的水体、安全用水是避免感染的关键。 当生产和生活必须接触疫水时，可以通过穿戴防护用品（胶手套、胶鞋、胶衣、胶裤等）、涂抹防护霜（剂）、预防性服药来预防感染血吸虫。 若感染如何治疗？ 当不可避免地接触了疫水，出现了发热等症状或脱离水体一个月后，应主动及时到血吸虫病防治机构或疾病预防控制机构进行检查以便诊断和治疗。
五 | 如果确认感染，吡喹酮是目前唯一在血吸虫病流行区广泛使用的高效、低毒、使用方便的口服抗血吸虫药物。服药时应谨遵医嘱，加强随访。 眼下正值春暖花开之际 出游务必做好防护！ （中国小康网微信公众号综合北京日报、中国疾控中心、广州日报、扬子晚报） 图源：网络 编辑：武金洋 审核：田苑淯颖。
