Fig. 1 — PCR detection of influenza A and picornavirus during the 1999–2000 winter season. The number of samples received at the laboratory each week during the winter respiratory season is shown in comparison to the number of consultations (per 10,000 population) for influenza-like illness reported to The Scottish Centre for Infection and Environmental Health (SCIEH) by the general practitioner sentinel network. The number of samples which were influenza A positive, picornavirus positive or negative for influenza A and B, picornavirus and RSV by nested PCR are shown for each week. Key: (○) total samples received; (▵) sentinel GP reports of influenza-like illness; (■) influenza A PCR positive; () picornavirus PCR positive; () PCR negative samples.
