HPS National Influenza Report - Week ending 27 April 2014 01 May 2014

This report provides an update on influenza and other seasonal respiratory pathogen activity for the week ending 27 April 2014. For this season, we will provide detailed influenza update reports on a monthly basis with bulletin style weekly updates in the weeks in between.

This report contains summary epidemiological information on influenza-like illness (ILI), its severity and impact in the community and secondary care settings, and vaccine uptake estimates.

The GP consultation rate for influenza-like illness (ILI) and the threshold for normal seasonal activity have been calculated using a new method this season which the European Centre for Disease Prevention and Control (ECDC) is recommending should be used across the EU. Please refer to the technical document for further information.

A guidance document has been issued by HPS with recommendations for the antiviral treatment and prophylaxis of influenza for the season 2013-14..

Influenza clinical activity remained low overall. Virological activity has fallen this week, and there were few severe cases of influenza reported suggesting community circulation of influenza may be decreasing.

In week 17, the levels of respiratory syncytial virus (RSV), adenovirus, parainfluenza virus, human metapneumovirus (hMPV) and Mycoplasma pneumoniae (MPN), reported through non-sentinel sources (ECOSS), decreased and were within expected levels. The levels of rhinovirus and coronavirus decreased but remained above seasonal expected levels.

In week 17, the levels of rhinovirus, reported through sentinel sources, decreased but remained above the expected seasonal levels. The levels of RSV, parainfluenza, MPN, coronavirus, adenovirus and hMPV were low and within expected seasonal levels.

Please note that the data for week 17 must be interpreted with caution, due to reporting delays resulting from the reduced number of working days over the holiday period.

Since week 40 2013, a total of 87 ICU cases have been reported to HPS (80 A(H1N1)pdm09, four A(H3N2) and three A(not subtyped)).
