Yunnan Province Reports 4 Recent H7N9 Cases


Until February of this year, Yunnan Province had never reported a human H7N9 infection (see Yunnan: 2nd Imported H7N9 Case (Mother of Last Week's Case). While those cases were reported as imported, today the Yunnan Provincial Health & Family Planning Commission is reporting 4 recent, apparently locally acquired, cases.
Wenshan City confirmed four cases of H7N9 cases

There is no indication on how any of these 4 cases were infected, or if any of them have epidemiological links between them.
Wenshan City is only 100 km from the Vietnamese border town of Lao Cai, which is sure to capture the attention of the Vietnamese health authorities  who have been on constant vigil  over the potential arrival of H7N9 all winter (see H7N9 Inches Closer To Vietnam's Northern Border).

An outbreak this far south, and this deep into the summer, is yet another sign that H7N9 continues to move in unexpected ways (see EID Journal: 2 Expedited HPAI H7N9 Studies).
