The first known epidemic of extensively drug-resistant typhoid is spreading through Pakistan, infecting at least 850 people in 14 districts since 2016, according to the National Institute of Health Islamabad.

Caffeine tied to babies born overweight

Consuming caffeine during pregnancy may increase the risk for obesity in childhood, researchers report. A Norwegian study, in BMJ Open, involved 50,943 mother-infant pairs. After adjusting for other variables, the scientists found that compared with the children of women who consumed less than 50 milligrams of caffeine a day, those whose mothers had more than 300 milligrams a day — two to three cups of coffee — were 29-44 percent more likely to be overweight through age 8.
