...disease appears to be transmitted. "Given that the explosion of the epidemic was mainly in the same area and some patients passed on the disease to family and doctors gathered in the hospital ward," the report states, "we think the disease is passed through breathing in flying particles of saliva...
...working theory, says Dr. Tam, is that the illness is spread by airborne respiratory mucous and saliva droplets. In Hong Kong, where 47 patients were under observation for pneumonia by the end of last week, the Department of Health urged at-risk hospital workers to wear protective gloves, masks and gowns...

In extreme cases, chapping leaves lips vulnerable to cold sores, which are caused by the herpes virus and triggered by stress, colds or flu.

They’re asked to anonymously fill out a survey and submit a sample of saliva to test current hormone levels. Chapman’s team photocopies students’ hands to test for a correlation between finger length ratios and testosterone levels. A larger difference between the fourth and second fingers indicates a greater prenatal exposure to the hormone. And if the joy of pure science doesn?...
