RESUMO

The primary aim of the Danish enterovirus (EV) surveillance system is to document absence of poliovirus infection. The conflict in Syria has left many children unvaccinated and movement from areas with polio cases to Europe calls for increased awareness to detect and respond to virus-transmission in a timely manner. We evaluate the national EV laboratory surveillance, to generate recommendations for system strengthening. The system was analysed for completeness of viral typing analysis and clinical information and timeliness of specimen collection, laboratory results and reporting of clinical information. Of 23,720 specimens screened, 2,202 (9.3%) were EV-positive. Submission of cerebrospinal fluid and faecal specimens from primary diagnostic laboratories was 79.5% complete (845/1,063), and varied by laboratory and patient age. EV genotypes were determined in 68.5% (979/1,430) of laboratory-confirmed cases, clinical information was available for 63.1% (903/1,430). Primary diagnostic results were available after a median of 1.4 days, typing results after 17 days, detailed clinical information after 33 days. The large number of samples typed demonstrated continued monitoring of EV-circulation in Denmark. The system could be strengthened by increasing the collection of supplementary faecal specimens, improving communication with primary diagnostic laboratories, adapting the laboratory typing methodology and collecting clinical information with electronic forms.

RESUMO

BACKGROUND AND OBJECTIVES: Denmark experienced three waves of the new pandemic influenza A (H1N1)pdm09 from July 2009 to February 2011. The aim of the study was to describe the epidemiology and clinical characteristics of hospitalized patients in a defined population of North Denmark Region with a mixed urban and rural community of 579,000 inhabitants. METHODS: Review of medical records of all hospitalized patients with confirmed influenza A from July 2009 to February 2011. RESULTS: Two hundred and seventy-three patients were admitted to hospital. The age-related population incidences of hospitalization were as follows: 0-14 years: 111/100,000, 15-64 years: 39/100,000, and ≥ 65 years: 17/100,000. During the first wave (July 2009-August 2009), three patients were admitted - none received treatment in intensive care units (ICUs), during the second wave (October 2009-January 2010), 158 patients were admitted - nine received treatment in ICUs, and during the third wave (December 2010-February 2011), 112 patients were admitted - 25 received treatment in ICUs. Fourteen patients (5%) died within 30 days of diagnosis (median 55 years; range 14-76 years) and additional seven patients (2.6%) died within 365 days (median 25 years; range 1-86 years). CONCLUSIONS: Patients hospitalized with pandemic influenza A (H1N1)pdm09 were predominantly children and younger adults, and only a few patients were >65 years. The third wave was the most severe taking the number and percentage of patients admitted to ICUs and 30-day mortality into consideration. We observed that the incidence of hospitalizations as well as clinical severity among younger adults did not decline from the second to the third wave.
