    Sharon-san, Long time no see you! : LOL
    Though you might know following news, I dare to post it. This is the 13th Bird-to-Bird outbreak H7N9 cases.
    And the MOA says there was no positive result for animal sampling test in March, the H7N9 virus is still atacking the birds.
    As for the human infection, no reports has been notified by the National or Local HFPCs.
