The World Health Organization is celebrating the eradication of another strain of the polio virus. Yet major challenges remain in the global effort to get rid of the disease.

As the U.S. grapples with the opioid crisis, pain medication is in short supply in some other parts of the world. One nurse in the Gambia explains how she addresses pain with tools other than drugs.

Parts of the island nation are still in ruins, thousands remain displaced and rebuilding efforts have only just begun. But locals and volunteers are making a difference.

Soon after Hurricane Dorian struck the northern Bahamas last month, aid groups like Team Rubicon went to the hard-hit island of Abaco, where they are helping the community to rebuild and recover.

Hurricane Dorian exposed a delicate issue: Haitians who are in the Bahamas illegally. Thousands were living on Abaco Island before the storm and were an important part of the local economy.

When Hurricane Dorian hit the northern Bahamas a month ago, it shattered lives and ripped apart a delicate economy. Now, business owners are debating how to rebuild and whether it even makes sense.

It's been four weeks since Hurricane Dorian pummeled, flooded and scoured the northern Bahamas leaving the island of Abaco barely habitable. Dozens died and hundreds remain missing.

It's been a month since Hurricane Dorian slammed into the Bahamas. The hardest hit area was Marsh Harbour which is still struggling to come back. Most residents have fled, further slowing recovery.

While the opioid problem in the U.S. is about too many opioids, in some countries there are few options for treating or controlling pain.

In the Bahamian capital of Nassau, officials are dealing with thousands of evacuees from the hurricane-ravaged islands of Abaco and Grand Bahama. The problem they face is how to accommodate them all.

"Anywhere we could put a warehouse has been destroyed by floodwaters and may not be safe for storing supplies," one aid group says of the widespread destruction brought by Hurricane Dorian.

After Hurricane Dorian devastated two islands in the northern Bahamas, people are debating whether to leave their homes. On hard-hit Abaco Island, people are discovering it's not a clear-cut decision.

Thousands of people were left homeless in Marsh Harbour after Hurricane Dorian. As the city struggles to recover, it's more than just Bahamians who are left with nothing as they look to rebuild.

An untold number of people died in Marsh Harbour, Bahamas, during Hurricane Dorian. For those who survived, the grim task continues about trying to learn who lived and who died.

People on the hurricane-devastated Bahamian island of Abaco are desperate for water, shelter and food. Supplies are beginning to arrive but the need is outstripping the supplies.

Recovery and rescue efforts are underway in the Bahamas after Hurricane Dorian. Also, health officials are looking at the role of vitamin E and vaping in respiratory illnesses.

In the hurricane-ravaged Bahamas, people are desperately trying to get off Great Abaco Island, one of the islands hardest hit by Dorian.

Rescue crews are starting to reach the Bahamian islands devastated by Hurricane Dorian. The official death toll of seven is expected to rise as the breadth of the disaster becomes clear.

Following the catastrophic damage left by Hurricane Dorian, the big question now is: How to get help to the people who are in places that can't even be reached?

Some researchers now say that tens of thousands of deaths due to kidney failure may be linked to climate change. But others aren't so sure.
