In accordance with UK policy, it was decided to offer antivirals to anyone who may have been exposed to the diseased poultry or had close contact with cases. By 30 May, 20 avian flu contacts had been identified who have or have had symptoms of an ILI or conjunctivitis. The National Public Health Service (NPHS) for Wales is using the following definitions of cases and contacts:
- A case is an individual with influenza-like illness (fever above 38° C, aches and pains, cough/head cold, sore throat or conjunctivitis) who has been in contact with affected premises or to known infected poultry (handling/within one metre) or close contact with another human case;
- A contact is defined as an individual who has been in contact with affected premises or with known infected poultry (handling/within one metre) or has had close contact with another person with confirmed or presumptive avian influenza.
As of 29 May, the NPHS had received microbiological test results from 12 patients in Wales. These were from swabs taken from the nose and throat and eyes. They were tested for the Influenza A viruses, including the H7 subtype that was isolated from the affected poultry. One test was positive for the H7 subtype and one for influenza A . Investigations are ongoing in the UK  and further results and updates will become available through the web-sites of the relevant authorities - the Health Protection Agency (www.hpa.org.uk), DEFRA (www.defra.gov.uk), the Welsh Assembly Government (www.wales.gov.uk) and the NPHS for Wales (www.nphs.wales.nhs.uk).
