Flu email update – Week 31

August 16, 2011

Update by Dr J Gallagher, Employment Health Advisors (EHA):
As of week 31 all indicators of influenza activity in Ireland continue to remain at low levels. The sentinel GP influenza-like illness (ILI) consultation rates remained low and below baseline levels. No positive influenza specimens were detected by the National Virus Reference Laboratory (NVRL). No confirmed influenza cases have been admitted to hospital or ICU during the summer period. No new general outbreaks of influenza/ILI have been reported since week 5 2011.

As of 29th July 2011, influenza activity in the temperate regions of the northern hemisphere remained low or undetectable. In the tropical zone, influenza transmission continued in a few countries of the Americas (Dominican Republic, El Salvador, and Colombia), western Africa (Ghana and Cameroon), and parts of Asia (India, Bangladesh, and Singapore). Influenza transmission in South Africa has declined to low levels, with mainly influenza A (H1N1) 2009 detections. In Australia, ILI consultations and laboratory-confirmed cases continued to increase. ILI activity in New Zealand has returned to baseline levels. http://www.who.int/csr/disease/influenza/en/
