Public Health England (PHE) Midlands are urging people, including members of voluntary wildlife organisations, not to touch sick or dead wild birds.
The call comes as PHE and the local authority work together after confirmed avian influenza A(H5N8) diagnosed in a number of swans in Evesham and following reports of a growing number of sick and dead swans around the Diglis area of Worcester.
With an increasing number of cases of the infection being seen across the country, on 11 November Defra declared the whole of England as an Avian Influenza Prevention Zone (AIPZ), to mitigate the risk of the disease spreading to poultry and captive birds. This means it is a legal requirement for all bird keepers to follow strict biosecurity measures and from 14 December all poultry and captive birds will need to be housed.
The A(H5N8) strain is highly pathogenic to other birds, however there have been no human cases of infection reported. While the risk to human health is considered very low, it is still vital that people do not touch sick live birds or bird carcasses, and infection control measures may be necessary if they do.
Dr James Chipwete, Consultant in Communicable Disease Control with PHE in the West Midlands, and lead consultant for flu, said: "During the last week there have been confirmed cases of avian influenza A(H5N8) in swans in Evesham, and we are receiving an increasing number of reports of sick and dead swans in the Diglis area of Worcester. We are awaiting results of investigations currently being undertaken by the Animal and Plant Health Agency (APHA).
"We know that people are concerned for the welfare of the swans, especially ensuring they are fed in these colder months, however it is important that people avoid contact with these sick or dead birds. Even though no cases of human infection have been associated with this strain of avian flu, as a precaution, anyone who was not wearing appropriate PPE while in contact with the droppings or birds in an area where the infection has been confirmed, will require close monitoring and a course of antiviral medication for 10 days from last contact with infected birds.
"We have seen a number of avian flu cases in poultry and captive birds across the country - with confirmed cases of A(H5N8) in Herefordshire last month, and suspected cases now in Warwickshire. People must avoid touching potentially infected birds at all costs, and if you do see any sick or dead birds by waterways or on your private land, please leave them and call the Defra helpline on 03459 335577. In areas where the infection has been confirmed, anyone who has been in contact with sick or dead birds or their droppings, while not wearing the correct PPE, should make sure any footwear is properly cleaned and thoroughly wash their hands in soap and water. They should then notify Public Health England's Health Protection Team on 0344 225 3560 to arrange for antiviral medication and active surveillance of their condition. If someone handled infected birds while wearing adequate PPE, they must still undergo active surveillance."
