The World Health Organization’s regional chief for Africa reports prospects for rapidly controlling the spread of the deadly Ebola virus in the Democratic Republic of Congo are good.

While not underestimating the difficulties that lie ahead in bringing this latest outbreak of Ebola to an end, Matshidiso Moeti told VOA she is “very encouraged” by the speed with which the government and its national and international partners have responded to this crisis.

“I am quite optimistic because this is a government that is experienced at this, and which has got off to a very quick start and we are already on the ground with the partners.  

“We are getting logistic support from WFP (World Food Program) and from the U.N. mission.  So, I am quite optimistic,” Moeti said.

WHO has reported 29 suspected cases, including three deaths since Ebola was discovered in a remote region of DRC on April 22.   This deadly virus causes fever, bleeding, vomiting and diarrhea.  It spreads easily through bodily fluids and can kill more than 50 percent of its victims.

This is the eighth recorded outbreak of Ebola in DRC since 1976.  The outbreak was first detected in Bas-Uele Province, a densely-forested area in northeastern Congo near the border with the Central African Republic.

Outbreak isolated

Moeti calls the remoteness of the area “a mixed blessing.”

She said that there was little likelihood of a “rapid expansion of the outbreak to other localities due to population movement as happened in West Africa.  Although, we are keeping a close eye on the Central African Republic … where we are concerned that there is insecurity there.”

She said it was difficult to operate and carry out surveillance or investigations in this area because the road network leading there was not very well developed and “we have to drive long distances, not in a car, but have to use a motorbike.”

To remedy this, she said the government had fixed up a landing strip to enable helicopters to fly in the experts and material needed to deal with this crisis.

Moeti, a South African physician, replaced Luis Gomez Sambo of Angola as WHO regional head for Africa in January 2015 after he was criticized for his lackluster leadership in handling the 2014 Ebola outbreak in West Africa.  

The World Health Organization has come under scathing criticism by the international community for its slow and inept response to that unprecedented epidemic.  By the time WHO declared the Ebola epidemic at an end in January 2016, the deadly virus had killed 11,315 people in Liberia, Sierra Leone, and Guinea.

Experience put to use

During a recent visit to Kinshasa, Matshidiso Moeti said she saw how the hard lessons that have been learned from this tragic experience were being applied in DRC.

“What I observed was that the government itself was very quick in getting out to this remote area from the central level.  

“So, they sent a team from Kinshasa within a day or two of getting this alert to go and investigate and from the provincial level very rapidly, the government got down into this local area,” she said.

Moeti is leading a reform process to transform the WHO in the African Region into what she called a “more responsive, accountable, effective and transparent organization.”

She told VOA that this process was a component of WHO’s global reform effort and she would be rolling out the plan during a side-event on May 22, the opening day of this year’s World Health Assembly.

She said the reform program focused largely on how to improve measures for more quickly and efficiently tackling emergencies and communicable diseases.

“Clearly, as we saw very starkly with the Ebola outbreak, an outbreak can quickly transform into a big humanitarian crisis with all sorts of impacts.”

While the job of health reform is far from complete, Moeti said, “I am really pleased to say that we are starting to see how those changes that we have made are making a difference in how we operate.”

A giant rhinoceros the size of three African elephants once grazed on treetops in Tibet, but succumbed to climate change more than 20 million years ago.

The high treetops disappeared, along with its food source, says Xiaohong Wang of the Natural History Museum of Los Angeles County. Wang has done field research on the long-legged rhino, more formally called the Indricotherium, one of the stars of a new exhibit that shows how radical adaptations that aid survival in one setting can spell disaster in another.

Through fossils and reconstructions, the exhibit tells the story of Mother Nature’s radical gambits to keep organisms alive in changing conditions. The show was built around an earlier exhibit from the American Museum of Natural History in New York, which also included ice age remains from the La Brea Tar Pits in Los Angeles.

Mammals that have adapted in the extreme include an ancient whale that walked on land and more recent pygmy mammoths on California’s Channel Islands, whose small size is illustrated with side-by-side jaw bones of a Columbian mammoth and its pygmy relative, which shrunk to cope with limited food resources on the islands.

Many species challenged

Climatic variations over the ages and the more recent incursion of humans have challenged many species, said Emily Lindsey of the La Brea Tar Pits, a site rich with fossils from the mammoths and giant cats that once roamed California, but died out more than 10,000 years ago.

Seen in the exhibit are the extinct American lion, “which along with the cave lion in Europe was the biggest cat that ever lived,” Lindsey said.

There are fossils from a scimitar cat, also extinct, and a long-gone subspecies of jaguar.

“And then we have the mountain lion, which is the only one of those five big cats that’s still alive today,” she notes.

Also known as the cougar, panther or puma, the species is represented with a photo of a celebrated cat that continues to roam through the hills above Los Angeles.

“People thought he would just spend a couple of days there, then continue to move on or attempt to move on,” said Miguel Ordenana, who coordinates the amateur citizens scientists who make wildlife observations to help scientists better understand the region. Mountain lions, he said, typically do not survive crossing busy freeways, but this intrepid mountain lion is a survivor, as is his species.

Arctic island was once like Florida

Other mammals in the exhibit include the Batodonoides, a long-extinct shrewlike mammal from 50 million years ago so tiny that it could have perched on a pencil. The South American Macrauchenia, with a camellike body and giraffelike neck, had a flexible trunk, like an elephant. It went extinct a mere 10,000 years ago, but is represented here in a reconstruction.

Earth’s extreme changes can be seen in a diorama of Ellesmere Island in the Arctic.

Just 1,000 kilometers from the North Pole, it was home to warm swamps 50 million years ago and a host of animals adapted to a Floridalike climate.

Those intense changes served many species well, but presented extreme problems. Especially as environmental conditions caused the Arctic freeze over, leaving Ellesmere Island one of the coldest and driest locations on Earth.

The challenges of adaptation and survival are the themes of a new exhibit at the Natural History Museum of Los Angeles. Mike O’Sullivan reports that the the exhibit, Extreme Mammals, shows the radical changes in animal species over millions of years and the extinctions of species that failed to adapt.

Recent studies suggest that as many as 400 million people around the world do not have access to basic health care. In some cases it’s because of conflict, but in some cases it’s just geography: humans live in some very far away places, Siberia for instance. That’s where the medical ship comes in handy. VOA’s Kevin Enochs reports.

Health ministers of the G20 leading economies, meeting for the first time Saturday, agreed to work together to tackle issues such as a growing resistance to antibiotics and to start implementing national action plans by the end of 2018.

Germany, which holds the G20 presidency this year, said it was an “important breakthrough” that all nations had agreed to address the problem and work toward obligatory prescriptions for antibiotics.

Pandemics

Saying that globalization caused infectious diseases to spread more quickly than previously, the 20 nations also pledged to strengthen health systems and improve their ability to react to pandemics and other health risks.

“By putting global health on the agenda of the G20 we affirm our role in strengthening the political support for existing initiatives and working to address the economic aspects of global health issues,” the communique said.

The results of the meeting will feed into a G20 leaders’ summit in Hamburg in July.

Overprescription

While the discovery of antibiotics has provided cures for many bacterial infections that had previously been lethal, overprescription has led to the evolution of resistance strains of many bacteria.

An EU report last year found that newly resistant strains of bacteria were responsible for more than 25,000 deaths a year in the 28-member bloc alone.

Germany has argued that even having a discussion about it will help raise public awareness about the problem. The G20 also said they agreed to help improve access to affordable medicine in poorer countries.

A warmer, wetter climate is helping push dozens of Eastern U.S. trees to the north and, surprisingly, west, a new study finds.

The eastern white pine is going west, more than 80 miles (130 kilometers) since the early 1980s. The eastern cottonwood has been heading 77 miles north (124 kilometers), according to the research based on about three decades of forest data.

The northward shift to get to cooler weather was expected, but lead author Songlin Fei of Purdue University and several outside experts were surprised by the move to the west, which was larger and in a majority of the species.

New trees tend to sprout farther north and west while the trees that are farther south and east tend to die off, shifting the geographic center of where trees live. 

86 tree species

Detailed observations of 86 tree species showed, in general, the concentrations of eastern U.S. tree species have shifted more than 25 miles west (45 kilometers) and 20 miles (33 kilometers) north, the researchers reported in the journal Science Advances Wednesday.

One of the more striking examples is the scarlet oak, which in nearly three decades has moved more than 127 miles (205 kilometers) to the northwest from the Appalachians, he said. Now it’s reduced in the Southeast and more popular in the Midwest.

“This analysis provides solid evidence that changes are occurring,” former U.S. Forest Chief Michael Dombeck said in an email. “It’s critical that we not ignore what analyses like these and what science is telling us about what is happening in nature.”

Dryer South, wetter West

The westward movement helped point to climate change, especially wetter weather, as the biggest of many culprits behind the shift, Fei said. The researchers did factor in people cutting down trees and changes to what trees are planted and where, he said.

With the Southeast generally drying and the West getting wetter, that explanation makes some sense, but not completely, said Brent Sohngen at Ohio State University, who was not involved in the study.

“There is no doubt some signature of climate change,” he said in an email. But given the rapid rates of change reported, harvesting, forest fires and other disturbances, are probably still playing a more significant role than climate change, he wrote.

Norway is repairing the entrance of a “doomsday” seed vault on an Arctic island after an unexpected thaw of permafrost let water into a building meant as a deep freeze to safeguard the world’s food supplies.

The water, limited to the 15-meter (50-foot) entrance hall in the melt late last year, had no impact on millions of seeds of crops including rice, maize, potatoes and wheat that are stored more than 110 meters inside the mountainside.

Still, water was an unexpected problem for the vault on the Svalbard archipelago, about 1,000 kilometers (620 miles) from the North Pole. It seeks to safeguard seeds from cataclysms such as nuclear war or disease in natural permafrost.

“Svalbard Global Seed Vault is facing technical improvements in connection with water intrusion,” Norwegian state construction group Statsbygg, which built the vault that opened in 2008, said in a statement on Saturday. “The seeds in the seed vault have never been threatened.”

Spokeswoman Hege Njaa Aschim said Statsbygg had removed electrical equipment from the entrance — a source of heat — and was building waterproof walls inside and ditches outside to channel away any water.

The number of visitors would be reduced to limit human body heat, she said. Some of the water that flowed in re-froze and had to be chipped out by workers from the local fire service.

An underlying problem was that permafrost around the entrance of the vault, which had thawed from the heat of construction a decade ago, has not re-frozen as predicted by scientists, Aschim said.

Temperatures in the Arctic region have been rising at twice the global average in a quickening trend that climate scientists blame on man-made greenhouse gases. Svalbard has sometimes had rain even in the depths of winter when the sun does not rise.

“There’s no doubt that the permafrost will remain in the mountainside where the seeds are,” said Marie Haga, head of the Bonn-based Crop Trust that works with Norway to run the vault. “But we had not expected it to melt around the tunnel.”

Haga said the trust had so far raised just over $200 million toward an $850 million endowment fund to help safeguard seeds in collections around the globe. “That is an extremely cheap insurance policy for the world,” she said.
