Drive out the birds
There is a close contact between birds and humans. Birds may be the transmission of diseases. Encephalitis, pneumonia and H9N2 avian influenza virus (AIV) are spread by the birds’ poop. The symptom seems to the influenza. Salmonella is a virus which is spread through birds’ poop to attract the pests (eg. Cockroach) for onward transmission to other positions or storage. There are some vectors (eg. fleas, ticks and mites) to hide below birds’ feather and you have to pay attention on disease transmitted also if you found the dead birds. In some cases, it may result in severe or fatal illness. Birds control is very important as pests control. You may install a suitable system to prevent the harmful birds attacked.
