Extremely Drug Resistant Tuberculosis XDR-TB - VOA Story
U.S. health officials have quarantined an airline passenger who may have exposed others to a potentially dangerous form of tuberculosis. The unusual decision was made after the passenger took flights from the U.S. to Europe, then to Montreal, Canada before reentering the United States. The man has what's called 'Extremely Drug Resistant' tuberculosis. Passengers and crew from both flights have been urged to be tested for the infection. XDR-tb is an especially virulent form of the disease that is resistant to standard drug treatment.
The World Health Organization says about nine million people around the world have TB and 1.6 million die from it every year. The greatest burden is in South and East Asia, followed closely by Africa and the Western Pacific regions, all adding up to 85 percent of the world total.
But TB persists and mutates into drug-resistant strains harder to cure because many patients fail to finish taking their medicine. For years, the World Health Organization has promoted directly observed therapy by local health care workers who go to patients' homes to make sure they take their pills. But in poor countries with weak health systems, health workers to do this are in short supply.
As a result, bacterial resistance to at least two common TB drugs is spreading, requiring newer, more expensive, and more toxic compounds to do the job.
"One of the biggest challenges is we know it's out there, but we don't know how much of it is out there," says Joann Carter. She is with the non-governmental group RESULTS, which helps fund medical projects in developing countries. She notes that an even more dangerous TB strain has developed recently. The bacterium has mutated further into a form resistant to most of the older and newer drugs. This so-called extremely drug resistant strain, or XDR tuberculosis, was first noticed in South Africa, fueled by the HIV epidemic that weakens patients' ability to fight such diseases.

Largest Shipwreck Treasure Find Ever - VOA Story
An American company is in the process of determining the value of a haul of sunken treasure, thought to be the biggest ever discovered. Odyssey Marine Exploration says it is examining more than half-a-million coins from the shipwreck as part of a find that could net it around half a billion dollars. The bounty has sparked public interest in the controversial business of treasure hunting vy Odyssey Marine Exploration.
"Black Swan is the code-name of a secret operation off the coast of Europe which may have discovered the biggest haul of shipwreck treasure ever found.
Odyssey won't reveal the identity of the ship, or even when it sank, to avoid giving clues to other treasure hunters. Odyssey will only say it went down in international waters.
In the crates are 17 tons of silver and gold coins and other valuables arriving in the U.S., destined for a secret location.
Mark Gordon, from Odyssey Marine Exploration, says an expert in 17th century coins estimated the value of the haul. "He looked at a representative sample of the coins and in amongst the group that he saw he was able to determine that there were values ranging from $400 to $4,000 for individual coins, and the mean value of the group that he looked at was about $1,000," says Gordon.
Those crates could hold about half a billion dollars. In the U.S., a big media splash about the "Black Swan" hoard has triggered a new fascination in pirate ships and treasure.
Odyssey estimates there are some three million shipwrecks worldwide. The company combs the seabed using a special underwater vessel: operating it costs $35,000 a day.
If treasure is found, the company determines if anyone may have a claim to it -- unlikely in the case of a pirate-ship -- then petitions a U.S. court to get ownership.
Odyssey is the only publicly traded treasure-hunting company in the U.S., but the business is unpredictable. It reported a net loss of $3.8 million in the first quarter of 2007.
Critics, such as the Institute of Field Archaeologists, accuse private companies like Odyssey of "ransacking" shipwrecks for profit. And Odyssey is in a legal wrangle with the Spanish government over the Black Swan treasure. Spain says it might be one of their galleons that went down in its territorial waters.
But Odyssey says it will press on with its work - and has even teamed up with the Walt Disney Corporation to cater to the public appetite for sunken treasure.
