BEIJING — Chinese authorities tried to calm spreading health concerns Wednesday after a third person was reported to have died from a new type of bird flu.
The emergence in China of the H7N9 strain of avian flu — a total of nine cases have been reported since it was revealed last weekend — are troubling because the strain has not previously been found in humans.
Even as two new cases were announced Wednesday, China’s state media sought to reassure the public that the chances of contracting H7N9 remain low. They also said that testing kits developed for the strain have been distributed to the national flu-monitoring network. Nothing so far, authorities stressed, suggests that the strain can be transmitted from one human to another.
The World Health Organization also urged calm this week but noted the importance of determining how the virus came to infect humans and whether it might spread. Just one patient so far appeared to have had direct contact with poultry. Dozens of people who came into contact with each patient are being monitored, authorities said.
A different strain of bird flu, H5N1, that emerged in 2003 has killed more than 360 people, according to the WHO.
Local media described the latest fatality Wednesday as a 38-year-old chef in the eastern province of Zhejiang.
A second patient from the same area was described as a 67-year-old retiree who was being treated in a hospital. Authorities revealed over the weekend that two other men had died in Shanghai.
