Pandemic Flu ‘The Bigger Picture’ Response! Shayne Ward Emergency Planning & Resilience Manager NHS Lincolnshire
Presentation Overview § Pandemic Flu – dispelling the myths! § Seasonal vs. Pandemic § Vaccines, Antivirals and Antibiotics § Bird Swine vs Human Influenza § Activation & Predicted Impact § Current International & National Levels § Activation vs. Response § Predicted Impact § The wider impacts of Pandemic Flu
Seasonal ‘flu vs Pandemic ‘flu ‘SEASONAL’ FLU PANDEMIC FLU • Occurs every year during the winter • Occurs about 3 times each century – at any time of the year • Affects up to 10% - 15% of the population • May affect up to 50% of the population • The very young, the very old • and people with certain chronic illness are most at risk • Annual vaccination available • • Antiviral drugs available for the at risk Vaccine won’t be available initially - in the first wave (Hope to be available in Autumn 2009) • Antiviral drugs available for up to 50% of the population (80%) People of every age may be at risk (Currently, its mainly under 19 Year Olds)
Previous ‘flu Pandemics • • • Pandemic Spanish Flu Strain: A(H 1 N 1) Year: 1918 -1919 Origin: Not known Estimated Deaths Global 20 -40 million UK 250, 000 Age Group 20 -50 yrs Asian Flu A(H 2 H 2) 1957 -1958 China Hong Kong Flu A(H 3 N 2) 1968 -1969 China 1 million 33, 000 under 14 yrs over 65 yrs 1 -4 million 30, 000 under 5 yrs over 65 yrs Shortest interval = 11 years Longest interval = 39 years Swine Flu 2009 A(H 1 N 1) Current interval = 40 years

Current interval = 40 years
Vaccines, Antivirals and Antibiotics Not Silver Bullet Solutions! § Vaccines § Offer protection against a ‘specific’ strain § Up to 4 -6 months to develop specific vaccine § Longer to manufacturer in sufficient quantities § Pre-pandemic vaccines – may offer Health Care Workers some protection but will not be exact ‘fit’ of pandemic strain (not applicable isn’t a strain of H 5 N 1!) § Antivirals § Is a counter-measure rather than protection § Reduces length of infection § Reduces severity and therefore secondary infections § Antibiotics § For counteracting secondary bacterial infections e. g. affecting lungs and heart

Pandemic Flu Activation
…by late April: Mexican Flu
…by late April: Oops! Mexican Swine Flu
World Health Organisation (WHO) pandemic flu alert levels • Swine flu was declared a pandemic on 11 June 2009 with the announcement of phase 6
NATIONAL ACTIVATION United Kingdom • When the international situation reaches WHO Phase 6 there will be 4 alert levels in the UK: • UK alert level 1 No cases in the UK • UK alert level 2 Virus isolated in the UK • UK alert level 3 Outbreak(s) in the UK • UK alert level 4 Widespread activity cross the UK
The National Service Framework Objectives of the National Flu Service Framework • to ensure that the right people get the right treatment at the right time, whilst enabling people who have flu to stay at home ; and to minimise the impact of influenza on the NHS.
The UK Government pandemic flu response • Antiviral stockpile – enough for 80% of UK population • Antibiotic stockpile – to treat and prevent secondary bacterial infections • Advanced purchase agreements for up to 132 million doses of pandemic-specific vaccine, when it becomes available. Enough for 100% of the UK population. • Face masks (for front line health and social care workers) • National Pandemic Flu Service • Guidance from the Department of Health and other bodies • Communication programme that includes TV, radio, internet, and leaflet drop
Local Response Strategy Mitigation Response The basis of a large scale response strategy will be • that the person with flu stays at home • antivirals are collected on their behalf from a designated local Antiviral Collection Point by a ‘flu friend’ 1. • Antivirals will only be issued if the patient fulfils the criteria set out in a clinical algorithm used by the National Pandemic Flu Service by Phone or Internet assessment. • UNDER 1’S & PATIENTS WITH CO-EXISTING CONDITIONS WILL BE SEEN BY GPs/HCPs • Plan for accessing antivirals for Care Homes • <15 residents use Flu Line • >15 residents – Health Professional / arrangements in line with local protocol.
SOCIAL CARE NATIONAL ACTIVATION
• Social care communications challenges To ensure that swine flu messages reach those who may be excluded from the national door drop and other mainstream communication channels, such as: – older people, especially if they live alone – people living in care homes – young people (research suggests under 24 s are less likely to receive/read the leaflet) – people for whom English is not a first language and/or who have literacy issues – people with a visual or hearing impairment – people with learning disabilities or mental health issues – street homeless and other groups without regular accommodation • Social care workers may need to act as ‘flu friends’ for vulnerable people who have no-one else to help them • Effective communication between local authorities and independent and third sector providers
Antiviral v Vaccine v Seasonal • Swine flu Vaccination Programme may run at same time as: - the programme for Seasonal Flu - the issue of Antivirals • Planning is under way • Some Groups, including front-line Health and Social Care workers to be prioritised for vaccination
