An outbreak of measles that popped up at Disneyland in late December soon spread to six other U.S. states, Mexico and Canada. Health officials suspect an infected traveler, who caught the virus overseas, visited the theme park and exposed others.

The outbreak sickened 147 people in the U.S., including 131 in California. No deaths were reported.

The three West African countries hit hardest by the Ebola epidemic called for an $8 billion "Marshall Plan" on Friday to help rebuild their economies and boost prevention efforts.

With the number of new cases having dwindled after the disease took more than 10,000 lives over the past year, Guinea, Liberia and Sierra Leone said they need much more financial aid to overcome the disaster and ensure it can't happen again.

A remote tribe in the Venezuelan Amazon appears to be resistant to modern antibiotics even though its members have had barely any contact with the outside world, researchers said Friday.

The people, known as the Yanomami, were first spotted by air in 2008, and were visited a year later by a Venezuelan medical team that took samples from 34 of them, including skin and mouth swabs and stool samples.

A new drug policy agency would focus as much on health as on policing under a proposal a New York City lawmaker introduced Thursday to shift how the nation's biggest city approaches illegal drug use.

The drug strategy office would advise city leaders on lowering drug-related deaths and disease along with crime. It also would coordinate answers to a problem that sometimes seems to pit one set of government objectives against another, supporters say.

The U.S. state of Georgia became the 24th U.S. state to legalize medical marijuana on Thursday, underscoring the increasing acceptance of the drug across America despite remaining an illegal substance under federal law.

Adrian Toomey made thousands of dollars a day as an "ice" dealer in Dubbo, a fairly typical Australian town northwest of Sydney, supplying the drug to everyone from bank workers to school teachers.

In the biggest survey of its kind, British researchers reported Wednesday that e-cigarettes are popular with young adolescents, but few who try them become regular users.

Of those who do use them regularly, most are also tobacco smokers, they added.

Estella Verdier keeps vigil by her sick four-month-old grandson's hospital bed, praying for his recovery but placing her faith in the earthly healing powers of Liberia's first ever children's hospital.
