LONDON — Chinese scientists have found the strongest evidence yet that a new bird flu strain is sometimes able to spread from person to person, but they are emphasizing that the virus still does not transmit easily.
The strain known as H7N9 was first reported by Chinese authorities in March. As of the end of May, there were 132 cases and 37 deaths in China and Taiwan linked to the virus.
Health officials suspect patients were most likely infected by birds in live animal markets but acknowledged sporadic cases of the virus probably were spreading among. . .
