In Scotland, clinical influenza activity is now increasing. Although activity is still at a low level, increases in a number of surveillance indicators including the number of outbreaks in closed settings (care homes/hospital wards), virological detections, and the number of severe cases of influenza, indicates community circulation of influenza is now occurring. The use of antivirals for the treatment and prophylaxis of seasonal influenza in the community is covered by the National Institute of Health and Clinical Excellence (NICE) technology appraisal guidance, endorsed for use in Scotland by NHS Healthcare Improvement Scotland (NHS HIS). The terms of this guidance are that the use of antivirals in the community for prophylaxis and treatment of patients presenting with influenza-like symptoms are subject to certain controls. These controls limit the use of antivirals to circumstances in which there has been documented evidence that influenza virus is circulating in the community. In light of the current surveillance picture reported above, the use of antiviral drugs for the prevention or treatment of influenza is now recommended in the community. Oseltamivir (Tamiflu) continues to be recommended, along with zanamivir (Relenza), for the prophylaxis and treatment of influenza. Health Protection Scotland and Public Health England have provided a summary of issues to consider in using antiviral agents for the treatment and prophylaxis of influenza. This document has recently been refreshed and republished in December 2014: http:// www.hps.scot.nhs.uk/resp/publicationsdetail.aspx?id=53562. The latest PHE/HPS review includes previously unpublished data, and adds to the evidence base for the treatment of influenza in some settings. Issues relating to this are detailed in a letter from the Scottish Chief Medical Officer (CMO(2014)29) circulated on 18 December at http://www.sehd. scot.nhs.uk/cmo/CMO(2014)29.pdf. ECDC Rapid Risk Assessment of influenza A virus drift 485103 The European Centre for Disease Prevention and Control (ECDC) issued a ‘rapid risk assessment’ on 22 December noting that data gathered since 1 October 2014 indicated that in the first ten weeks of the 2014-15 influenza season, viruses in EU/EEA countries had been predominantly A(H3N2) rather than A(H1N1)pdm09 and type B viruses. In previous seasons, influenza A(H3N2) viruses were associated with more severe disease than A(H1N1) and type B viruses; they were also associated with several outbreaks in long-term care facilities. These observations indicate that the 2014-15 influenza season may be associated with a greater number of cases with more severe disease, given the higher proportion of A(H3N2) strains among isolates typed to date and the early evidence of drift that is likely to be associated with reduced vaccine effectiveness. The circulating viruses are susceptible to the antiviral drugs oseltamivir and zanamivir. Physicians should therefore always consider treatment or post-exposure prophylaxis with antivirals when treating influenza-infected patients and exposed individuals in risk groups.

Shingles (herpes zoster) vaccine –contraindications 48/5105 Shingles (herpes zoster) vaccination for 2014/15 is underway, targeting people aged 70 years (routine) and 78 and 79 years (catch-up) in addition to those aged 71 who were not vaccinated last year. In the current issue of its Scottish Vaccine Update (issued on 15 December), HPS has reminded clinicians that shingles vaccine is a live attenuated vaccine and is therefore contraindicated for some patient groups. All patients need to be assessed for immunosuppression prior to administration of the vaccine. The current Scottish Vaccine Update can be accessed at http://www.hps.scot.nhs.uk/immvax/ scottishvaccineupdate.aspx. Full details are provided in Green Book Chapter on shingles (herpes zoster) https://www.gov.uk/ government/publications/shingles-herpes-zoster-the-green-book-chapter-28a.

FSA guidance on cooking frozen turkey 48/5106 The Food Standards Agency (FSA) launched ‘Defrost Your Turkey Day’ on December 22 with a view to minimising the risk of Campylobacter or other microbial contamination by way of the traditional Christmas lunch. HPS WEEKLY REPORT Volume 48 No.2014/51-52 24 December 2014 659 A recent FSA survey found 62% of the UK public would have turkey at Christmas and, of those who choose frozen turkey, 69% might defrost it in unsafely in such locations as the bath, garage or garden shed. The FSA reiterated its guidance on preparing turkey from frozen: • the retailer’s recommended defrosting time should be observed. The size of the turkey will determine how long it needs to be defrosted for (a large 11kg turkey can take up to two-days to defrost); • the turkey should be defrosted in the fridge if possible or somewhere cool. Cold temperature slows the growth of germs on food and will keep it safe and fresh; • while defrosting, the turkey should be covered, left in the packaging or put it in a container to hold any thawing juices, and placed it at the bottom of the fridge to avoid cross-contamination; • the turkey should be defrosted thoroughly, as otherwise it may not cook evenly and harmful bacteria could survive the cooking process; • raw turkey should always be put in the bottom of fridge until ready to use. Leaving on the kitchen counter at room temperature could increase the risk of food poisoning. It does of course follow that anyone who has not started defrosting the Christmas turkey by now has left it too late. The FSA guidance can found at http://www.food.gov.uk/news-updates/news/2014/13366/defrostyour-turkey-properly. EMA advice on the use of antibiotics in animals - update 48/5107 Further to Current note 48/3205 (at http://www.hps.scot.nhs.uk/ewr/redirect. aspx?id=59898), the European Medicines Agency (EMA) has published recommendations to limit the development of antimicrobial resistance (AMR) linked to the use of antibiotics in animals, thereby minimising at source the risk of transmission of resistance from animals to humans. The proposed measures focus in particular on promoting the responsible use in veterinary medicine of antibiotics that are critically important in human medicine such as fluoroquinolones and third and fourth generation cephalosporins. The advice (available at http://www.ema.europa.eu/docs/en_GB/document_library/Other/2014/07/ WC500170253.pdf) was developed by an interdisciplinary group of experts coordinated by EMA and has been sent to the European Commission to inform their action plan against the rising threats from antimicrobial resistance. The emergence and steady increase of bacteria that are resistant to several antibiotics has become a global public health threat. It is a priority for public health authorities worldwide to strengthen measures for the prevention and control of antimicrobial resistance to keep antibiotics effective for future generations. It is hoped that the advice will act as valuable input into the discussions that have now started in the European Council and the European Parliament on the proposal for revision of the legislation covering veterinary medicines.

New information about the presence of exotic mosquito species in Europe is available in the updated mosquito maps, specifically about the Aedes albopictus in Bulgaria, France, Germany, Greece, Slovenia and Switzerland and regarding Aedes japonicus in Austria, Hungary, the Netherlands and Slovenia. The maps are the outcome of the collaborative work of VectorNet – a joint initiative of the European Food Safety Agency (EFSA) and the European Centre for Disease Prevention and Control (ECDC) that started in May 2014. The project supports the collection of data on vectors, related to both animal and human health. ECDC and EFSA create a common database on the presence and distribution of vectors and pathogens in vectors in Europe and the Mediterranean through developing a network of experts and organisations from the medical and veterinary domains. The project aims to extend the network of medical entomologists and public health professionals, already established during the VBORNET project, and include veterinary entomologists and veterinarians.

A Defra-commissioned survey found that: • 25% were not aware of the restrictions on bringing in meat and live plants, while 37% did not know the rules on dairy products; • 58% of respondents didn’t realise pests and diseases could be carried on meat products; • 64% didn’t realise dairy products could carry disease; and • approximately half of those surveyed who had brought back restricted products had not gone with the intention of doing so. Holidaymakers wanting to bring gifts back for friends and family from countries outside the EU may not be breaking the law intentionally, but it can be easy to impulse buy. There are, however, strict rules in place to protect Britain from pests and diseases that affect plants and animals. This is vitally important to safeguard the economy, the environment and our health. Disease outbreaks can lead to bans on UK exports and have a major impact on natural habitats and native species. What might seem like a harmless looking plant cutting could be harbouring a destructive pest or disease. For example, Asian Longhorn Beetles can travel on plants and on wood packaging, and will attack and kill a range of hardwood trees. The beetle was brought into Britain in 2012 and swift action was taken to eradicate it. The survey also revealed few understood the consequences of breaking the rules. Over 70% didn’t realise they could face travel delays if they were found carrying restricted products, and almost 20% didn’t know that they might have the item confiscated. Border staff often inspect luggage so travellers may be subject to checks on return. HPS WEEKLY REPORT Volume 48 No.2014/51-52 24 December 2014 661 Information on the rules on what can and can’t be brought back is available at: Bringing food, animals or plants into the UK (https://www.gov.uk/bringing-food-animals-plants-into-uk/petsand-other-animals). [Source: Defra Press Release, 19 December 2014. https://www.gov.uk/ government/news/christmas-holidaymakers-remember-dont-bring-back-a-bug-in-your-bags] Travel, transport and the environment 48/5110 Europeans collectively travelled 6.4 trillion kilometres in 2012, according to the Transport and Environment Reporting Mechanism (TERM) 2014. While car transport made up more than 70 % of this distance, it has continued to decline since 2009. In contrast, air transport has increased very fast over recent decades. One factor behind this pattern may be changing consumption habits. Some research suggests that younger generations prefer to spend their disposable income on long distance travel rather than consumer products such as cars. Nonetheless, there is a wide variation across the EU. Per capita car travel peaked in 2004 in the original 15 EU member states, while it continues to grow in the 13 newer members. Overall passenger transport demand fell 1.4% in 2012, mainly due to the drop in car passenger travel. Freight transport volumes also fell in 2012, by 2.1%. Transport’s total energy demand has also fallen, continuing its year-on-year decline since demand peaked in 2007. Because these trends may be partly caused by the recession, it is unclear whether this will rebound in coming years. Greenhouse gas emissions from transport fell 3.3% in 2012, although they must continue to fall drastically meet targets over coming decades. Air pollutant emissions from most transport modes also decreased, apart from air pollution emitted by planes which increased for some pollutants. However, air quality is still harming health in Europe’s cities. Levels of nitrogen dioxide and particulates in cities have been exacerbated by increasing proportions of diesel cars. This is partly a result of fuel tax policies in most European countries, which give preference to diesel over petrol-driven equivalents. [Source: EEA Highlight, 8 December 2014. http://www.eea.europa.eu/ highlights/more-action-needed-to-reduce] Further to this, more than 125 million Europeans could be exposed to levels of road traffic noise above legal guidelines. This causes a range of health problems, according to a new assessment from the European Environment Agency (EEA). ‘Noise in Europe 2014’, published on 19 December by the EEA, analyses exposure to noise levels and resulting environmental health problems. The effects of noise are particularly widespread. For the one in four Europeans exposed to noise levels above the EU’s threshold for assessment and action, there are both direct and indirect health effects, the report states. Traffic noise annoys almost 20 million Europeans and disturbs the sleep of an estimated eight million. Environmental noise is also linked to approximately 43 000 hospital admissions, 900 000 cases of hypertension and up to 10 000 premature deaths per year, the EEA estimates.

GP practices should familiarise themselves with the Scottish Government guidance on the new notification requirements at: http:// www.scotland.gov.uk/Topics/Health/Policy/Public-Health-Act. Registered medical practitioners report notifiable diseases based on ‘clinical suspicion’. As such, notifications may not be subject to laboratory report confirmation. The published figures will record therefore how many diseases have been clinically suspected. Patient notifications can, however, be reclassified. When, for example, a suspected (and notified) tuberculosis case is subsequently reported as negative by a laboratory (and found not to be a health protection risk) it would subsequently be removed from the disease totals. Diseases to be notified by registered medical practitioners with effect from 1 January 2010: Notifiable Diseases which come into effect on 1 January 2010 *Anthrax *Meningococcal disease *Botulism Brucellosis *Cholera Mumps *Necrotising fasciitis *Paratyphoid *Clinical syndrome due to E. coli O157 infection (see note 1) *Diphtheria *Haemolytic Uraemic Syndrome (HUS) *Haemophilus influenzae Type b (Hib) *Measles *Pertussis (Whooping Cough) *Severe Acute Respiratory Syndrome (SARS) *Smallpox Tetanus Tuberculosis (respiratory or non-respiratory) (see Note 2) *Tularemia *Plague *Poliomyelitis *Typhoid *Viral haemorrhagic fevers *Rabies *West Nile fever Rubella Yellow Fever It is recommended that those diseases above marked with an * require urgent notification, i.e. within the same working day. Note 1: Escherichia coli O157 Clinical suspicion should be aroused by (i) likely infectious bloody diarrhoea or (ii) acute onset non-bloody diarrhoea with a biologically plausible exposure and no alternative explanation. Examples of biologically plausible exposures include: • contact with farm animals, their faeces or environment; • drinking privately supplied or raw water; • eating foods such as undercooked burgers or unpasteurised dairy products; • contact with a confirmed or suspected case of VTEC infection. Further guidance is available at: http://www.hps.scot.nhs.uk/giz/e.coli0157.aspx. Where a case is notified as HUS (Haemolytic Uraemic Syndrome) it should NOT also be notified as ‘Clinical syndrome due to E. coli O157 infection’. HPS WEEKLY REPORT Volume 48 No.2014/51-52 24 December 2014 664 Note 2: Tuberculosis For the purposes of notification, respiratory TB or non-respiratory TB should be taken to have the same meanings as the World Health Organisation definitions of pulmonary TB and nonpulmonary TB respectively: Pulmonary TB is tuberculosis of the lung parenchyma and/or the tracheobronchial tree. Non-pulmonary TB is tuberculosis of any other site. Where tuberculosis is clinically diagnosed in both pulmonary and non-pulmonary sites, this should be treated as pulmonary TB. Registered medical practitioners have been advised to contact their local NHS Board Health Protection Team for advice should they have any doubts about the diagnosis of suspected cases. Non-notifiable diseases Registered medical practitioners are no longer required to notify the diseases listed below. • Bacillary dysentery • Chickenpox • Food poisoning • Scarlet fever • Viral hepatitis These diseases are now covered by a list of notifiable organisms details of which will be reported by laboratories to health protection teams.
