You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Foremost was the concern that if initial laboratory testing capacity concentrated on ill people with links to affected countries or who were in close contact with patients whose symptoms had been microbiologically confirmed , 3 then surveillance would fail to recognise the extent to which local community transmission was occurring . 4 In addition , existing syndromic surveillance systems might not have been sufficiently specific during the early stages of the epidemic . The influenza syndromic surveillance capability of the Health Protection Agency ( HPA ) includes the Royal College of General Practitioners ( RCGP ) Weekly Returns Service 5 and the QSurveillance system ( University of Nottingham and Egton Medical Information Systems Ltd ) , which analyse anonymised morbidity data automatically extracted from networks of participating general practices . 6 Since the beginning of the influenza A / H1N1 2009 epidemic , general practice diagnoses of influenza - like illness and a range of other respiratory tract infections ( rates per 100 000 population ) have been monitored on a daily ( QSurveillance ) and weekly basis ( QSurveillance , RCGP ) , providing information for regular situation reports . 7 Throughout May and most of June 2009 , however , general practice consultation rates for influenza - like illness remained well below the upper limit for " baseline activity " of 30 cases per 100 000 population . Only during the second half of June did a clear increase in consultation rates became apparent in either the RCGP system or the QSurveillance system . 8 One response to the perceived poor specificity of syndromic surveillance for recognising illness caused by the novel virus was the re - introduction of virological testing . During each influenza " season , " a programme of integrated nose and throat swabbing is conducted within the RCGP system . 9 In addition , the HPA operates a Regional Microbiological Network general practice spotter scheme . 10 Both systems were re - instigated to enhance community based virological surveillance . In May 2009 , however , there was unease that the geographical scope of these sentinel virological sampling systems may have been too limited so that sustained community transmission may have been underascertained once begun and if concentrated in a few places . Moreover , once members of the public with suspect flu symptoms were advised in early May 2009 not to attend general practitioner surgeries or accident and emergency departments unless they were seriously ill or advised to do so , 11 the case mix of those receiving primary care from their general practitioners was likely to have changed .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
