A five-year-old toddler has died from the bird flu virus in Jakarta, Indonesia, officials said on Thursday.
The H5N1 virus also claimed the lives of a man in Vietnam and of a toddler in Cambodia this week.
The three deaths bring the total number of avian influenza fatalities in the region to five in the last three weeks.
A man diagnosed with China’s first case of bird flu in more than a year died in Shenzhen on 31 December. A man died in Jakarta, Indonesia on 7 January.
It is believed that the 23-year-old was a family member of the toddler, and they were both in contact with sick pigeons.
The World Health Organization says the H5N1 strain of the bird flu virus has killed 342 people since 2003.
In South East Asia Vietnam has seen one of the highest numbers of deaths, with 59 fatalities since 2003, according to WHO data.
The 39-year-old Shenzhen bus driver, however, was believed to neither have been in contact with poultry or travelled recently
