An American nurse has become the first person to contract Ebola in the U.S., raising fear and alarm about the outbreak in the West.
In the Ebola hotzone of West Africa, desperation grows as thousands of people are struck by the deadly virus - including healthcare workers on the front line.
The outbreak may be spreading, but professor and senior United Nations advisor Jeffrey Sachs tells me Ebola can be controlled in 6 months.
"This is a controllable epidemic but the epidemic has so far outrun the control efforts," he says.
"This is logistics, it's equipment, it's basic health protocols, it's diagnostics. All the pieces of a basic control system that need to be rapidly scaled up."
Watch the video to hear his recommended next steps, and what is at stake for Africa and the world if Ebola is not contained.
These are highly charged political times here in Hong Kong.
Beijing announced on Sunday there would be no open elections in Hong Kong, paving the way for China to remain the political power over the territory.
During this time of intense political discord, a gripping image from 1967 is a reminder of the fraught relationship between Hong Kong and Beijing.
It's a Chinese propaganda poster issued during the Leftist riots to stir people in Hong Kong rise up against British rule.
Recently on display at Hong Kong's Picture This Gallery, the poster depicts an angry, muscular crowd wielding placards and other objects as weapons.
In the bottom left-hand corner, weak cartoonish figures depicting the colonial government are being beaten and kicked out by the crowds.
"This was produced in China, probably smuggled into Hong Kong and used to try to rally support among patriotic Chinese living in Hong Kong," Bailey tells me.
The poster was part of an exhibition of Chinese propaganda that include a Norman Rockwell-esque public service announcement and a red balloon-strewn commemorative poster of Deng Xiaoping and the Hong Kong handover.
Bailey says the 1967 Hong Kong posters generated the most interest in his gallery and will find a new home in a museum.
Take a tour of these Chinese propaganda posters with the video above.
It is indeed an historic occasion.
U.S. President Barack Obama is hosting the first-ever U.S.-Africa Leaders Summit in Washington.
But the leaders of Sierra Leone and Liberia are not there. They have opted to stay at home to battle the worst Ebola outbreak on record.
"The timing is very unfortunate, and no one would have wished for this," author and academic Howard French tells me.
"Having high-level discussions between the U.S. and Africa on business and investment are infrequent. So to the extent that this distracts from that I think will be regretted all around."
The summit is a much-needed opportunity for the U.S. to reset relations and economically engage with Africa.
"Africa is in a very particular moment, economically speaking," says French. "The continent has been growing very fast. Demographically, there's a bulge in terms of its youth population. And Africa needs partnerships."
Africa's biggest trading partner is China. It has invested deeply into Africa as a source of customers, natural resources, and jobs.
Howard French refers to Africa as "China's Second Continent" as more than a million Chinese citizens have permanently moved there.
But will China's engagement with Africa lead to prosperity or exploitation?

Since 2005, Hong Kong-based photographer Jo Farrell has been on a mission to document China's last women with bound feet.
It was a symbol of beauty and social status that began in the Song dynasty but officially banned over a hundred years ago. But the practice continued in rural areas for a few years after the ban.
Farrell has spent a decade traveling to China’s Shandong and Yunnan provinces to forge a close relationship with 50 of China’s last women with bound feet.
Those women are now in their 80s and 90s. In this video, we discuss the brutal practice of foot binding and Farrell's sense of urgency to share her portraits of their "lotus feet."
Since the handover in 1997, Hong Kong has been ruled under the governing principle of "one country, two systems."
But a white paper issued this week by China's State Council Information office is trying to set the record straight, emphasizing Beijing's "comprehensive jurisdiction" over the territory.
The white paper puts forward the view that some Hong Kong residents are "confused or lopsided in their understanding" of the principle.
It says, "The high degree of autonomy of the HKSAR (Hong Kong Special Administrative Region) is not full autonomy, nor a decentralized power. It is the power to run local affairs as authorized by the central leadership."
Political columnist and commentator Frank Ching calls the paper a clear warning to Hong Kong, pointing out a line about Beijing's right to declare a state of emergency in Hong Kong.
"If they declare a state of emergency, that means the People's Liberation Army can come in and take over the job of Hong Kong police."
He adds, "That would be the end of Hong Kong as we know it today."
Ching also makes an interesting observation about why the paper was released in seven languages.
"It's warning foreign countries not to use Hong Kong as a base for subversion."
"If history tells us anything it's that whistle-blowers are usually treated kindly, and claims of national security much less so."
Here's my interview with Edward Snowden's legal adviser, Ben Wizner, one year after Snowden revealed himself as the NSA leaker.
Shen Tong is a Chinese dissident who helped lead the Tiananmen Square protests in 1989.
Ahead of the 25th anniversary of the crackdown, I asked him about his experience during the demonstrations, and the chilling moment when he realized troops were not shooting rubber bullets.
We also talked about a lack of awareness in China about what happened back then.
"It seems like there is a collective amnesia not only due to the lack of information but also due to at least this tacit agreement between the post-'89 police state and the urban population," he tells me via satellite from New York.
"'Let’s forget about the past and why rock the boat' because there are several groups of elite populations, not just in China, that are making so much money so quickly."
But Shen is certain that the collective amnesia concerning Tiananmen will inevitably lift.
"There are plenty of indications that collective memory, so important to the national psyche, cannot be forgotten," says Shen.
"So even though a lot young people don’t know the details... those memories can come back very quickly as we’ve seen time and again in history."
Before his arrest in 2009, Nobel Peace Prize laureate Liu Xiaobo would write a poem every year to commemorate the 1989 Tiananmen crackdown.
The poems have been translated into English by Jeffrey Yang and published in the compilation, "June Fourth Elegies."
I talked to Yang about Liu Xiaobo's poetry, and the power of poetry to remember an event that has been publicly erased in China.

Many CNN viewers know him as Mira Sorvino's guide in "Every Day in Cambodia," the 2013 CNN Freedom Project documentary that fixed a spotlight on child sex trafficking in the country.
American activist Don Brewster has dedicated his life to saving Cambodia's children. As the founder of Agape International Mission, he has helped rescue hundreds of girls from sexual slavery.
In Hong Kong, I talked to Brewster about how he tracks down Cambodia's enslaved girls, helps to rebuild their lives, and equips local communities to join the fight against the despicable trade.
Brewster also tells me about the impact of the Freedom Project documentary, and how it has led to justice for some of the girls in Cambodia.
