A cruise ship has returned to South Florida after concluding a Caribbean voyage that saw more than a hundred people develop a gastrointestinal illness on board.

Royal Caribbean International reported Friday that 105 of 1,991 guests and three of 772 crew members experienced a possible short-lived norovirus illness during the 11-night trip.

A decade ago, a highly contagious and deadly new illness sent people worldwide scrambling to cancel flights and holidays as schools closed and sales of surgical masks spiked.

Severe Acute Respiratory Syndrome (SARS) was the first "new" disease of the 21st century to jump from an animal host to humans, then easily from one person to another.

Pakistani tax authorities took the unusual step Friday of threatening retailers with heavy fines and prison unless they stop selling cigarettes smuggled from South Korea.

Willpower apparently can be bought. The chance to win or lose $20 a month enticed dieters in a yearlong study to drop an average of 9 pounds (4 kilograms)— four times more weight than others who were not offered dough to pass up the doughnuts.

Aid agencies and governments must tackle the taboos surrounding menstruation as sidelining the issue undermines the quality of life of women and girls, chiefly in poor nations, a U.N. body said Wednesday.

Poor education about menstruation, lack of access to sanitary napkins and painkillers for cramps, and inadequate washing and disposal facilities have a far-reaching impact on schooling, work and health, the Water Supply and Sanitation Collaborative Council said.

A high-salt diet may be a risk factor for autoimmune diseases like multiple sclerosis (MS), according to three papers published in the journal Nature on Wednesday.

Two of the studies showed that salt can induce the production of aggressive cells involved in autoimmune disease development in mice and humans, while a third indicated that mice on high-salt diets develop a type of disease similar to human MS.

Scientists said Thursday they had, for the first time, helped women with severe anorexia through electrodes implanted into their brains.

The technique is in an experimental phase and only some patients had improved, but the treatment showed promise, they wrote in the Lancet medical journal.

At a small and peaceful clinic on the outskirts of Yangon, 20 volunteers tend to 300 HIV patients abandoned by a health care system allowed to crumble during decades of brutal military rule in Myanmar.

In a country whose rulers long prioritized military spending over the needs of their people, these men, women and children have found a refuge thanks to the work of a member of Aung San Suu Kyi's opposition party.
