No new human cases of the H7N9 virus have been recorded in China for a week, national health authorities said, for the first time since the outbreak began in March.
One previously infected patient died in the week beginning between May 13, the National Health and Family Planning Commission said in a statement late on Monday, taking the total number of fatalities from the virus to 36.
But the number of confirmed cases was unchanged at 130. Of those, 72 have recovered and been discharged from hospital, it said, adding that no evidence of human-to-human transmission had been detected so far.
Experts fear the possibility of the virus mutating into a form easily transmissible between humans, with the potential to trigger a pandemic.
Flu viruses are often seasonal and much of China is experiencing warmer weather following the end of winter.
But the head of the World Health Organisation (WHO) warned that the evolution of the outbreak was still unpredictable.
