Mae parthau Rheoli Clefydau Dros Dro o 3km a 10km wedi'u gosod o amgylch yr eiddo bach sydd wedi’i heintio, i gyfyngu ar y risg o ledaenu’r clefyd. Mae ymchwiliad milfeddygol ar y gweill, fodd bynnag, mae adar gwyllt marw sydd wedi’u darganfod yn yr ardal wedi profi'n bositif am y feirws a chredir mai hwy yw ffynhonnell yr haint.
Temporary Disease Control zones of 3km and 10km have been imposed around the small infected poultry premises, to limit the risk of disease spread. A veterinary investigation is underway, however, dead wild birds found in the area have tested positive for the virus and are believed to be the source of infection.
