CNN News:刚果埃博拉疫情防控前景谨慎乐观 特朗普向盟友征收钢铝关税

Today's global coverage begins in Central Africa. International health officials say they have reason to be cautiously optimistic about limiting the spread of an Ebola outbreak in the Democratic Republic of Congo. It was first reported in early May. Since then, there'd been 54 cases identified in the DRC. That includes 25 people who've died from Ebola.
On average, the virus kills about half of those who get it. Most of the cases in this outbreak were in a rural area. But what alarmed medical officials a couple of weeks ago is that the disease had spread to a city named Mbandaka, where more than a million people live and there were concerns that it could spread quickly there.
So, doctors started vaccinating people. The World Health Organization says more than 400 had been vaccinated so far. The drug is experimental. It's not approved everywhere. But the officials using it say it's both safe in humans and highly effective against the Ebola virus.

AZUZ: At midnight Thursday night, new tariffs which were like taxes were set to take effect in the U.S. on imports from Canada, Europe and Mexico.
Steel now costs an additional 25 percent to bring in to America. Aluminum costs an extra 10 percent.
These tariffs were announced in March, but Canada, Mexico and the European Union were originally exempted from this, meaning the taxes didn't apply to them. Those exemptions expired last night.
Why are the tariffs in place? President Donald Trump wants to help the U.S. steel and aluminum industries by limiting what America brings in from other countries. This could help improve sales for the American metal producers. But it could also make it harder for the U.S. to sell other products in Canada, Mexico and Europe, because those nations announced they'd put tariffs on their own on U.S. goods.
Investors are also concerned that a trade war could flare up. Trade negotiations between the U.S. and the affected countries are ongoing.
