2017年以来首次 美国家禽农场出现H7N9禽流感

美国出现2017年以来首次在家禽农场爆发高度致命性的H7N9禽流感疫情。美国目前仍在应对另一种已感染人类,并导致鸡蛋价格创新高的禽流感毒株

路透社报道,总部位于巴黎的世界动物卫生组织(WOAH)星期一(3月17日)引述美国官方消息称,最新的H7N9疫情发生在密西西比州诺克苏比县,一个饲养4万7654只商品肉鸡的农场。

报告指出:“在密西西比州的一处商业肉鸡群中,检测出具有北美野鸟血统的高致病性禽流感(HPAI)H7N9病毒。目前,受感染家禽的扑杀工作正在进行中。”

美国农业部正与州动物卫生及野生动物官员合作,开展全面的流行病学调查,并加强监测,以应对此次疫情。

禽流感的传播已严重影响全球家禽群,扰乱供应链并推高食品价格。禽流感也已蔓延至哺乳动物,包括美国的奶牛,引发各国政府对新一轮大流行疫情的担忧。

近年来,对家禽造成最大损害,并导致美国一人死亡的禽流感毒株是H5N1。

然而,世界卫生组织说,自2013年首次发现以来,H7N9禽流感的致死率更高,感染者死亡率接近40%。

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.

That strategy is the acquisition of a value-priced company by a growth company. Using the growth company's higher-priced stock for the acquisition can produce outsized revenue and earnings growth. Even better is the use of cash, particularly in a growth period when financial aggressiveness is accepted and even positively viewed.he key public rationale behind this strategy is synergy - the 1+1=3 view. In many cases, synergy does occur and is valuable. However, in other cases, particularly as the strategy gains popularity, it doesn't. Joining two different organizations, workforces and cultures is a challenge. Simply putting two separate organizations together necessarily creates disruptions and conflicts that can undermine both operations.
