RESUMO
Approximately 13% of the UK population in 2015 was born overseas. Most migrants have come to the UK to work or study although there has been a small increase in the number of asylum applications in the UK in recent years, reflective of the ongoing humanitarian situation across Europe. Migrants in the UK tend to be young and healthy, but some may face unique health needs as a result of their experiences before, during and after migration. For these needs to be appropriately recognised and addressed, evidence-based advice is needed for UK professionals. The Migrant Health Guide is a free online tool for healthcare professionals. It was launched in 2011 and is widely used in the UK and internationally. It has four sections: 1) Migrants and the NHS-information on access and entitlements to the National Health Service (NHS); 2) Assessing patients-includes a checklist for initial healthcare assessments and advice for patients travelling abroad to visit friends and relatives; 3) Countries-country-specific advice on infectious diseases, women's health and nutritional and metabolic concerns; and 4) Health topics-information about communicable and non-communicable diseases and other health issues. The guide has undergone an extensive update in 2017. In particular, the pages on mental health and human trafficking have been expanded. A formal evaluation will obtain feedback on the guide and measure changes in awareness, knowledge, opinions, attitudes and behaviour of end users. Findings will inform future revisions and updates to the guide. Public Health England's Migrant Health Guide is a valuable resource for healthcare professionals. The relaunched guide builds on the previous version in raising awareness of key issues and providing evidence-based advice to improve the health of migrants and refugees internationally and in the UK.

A report on Toxoplasma gondii by the UK Advisory Committee on the Microbiological Safety of Food recommended that more accurate figures on the burden of disease in the UK are needed. We present the first 5 years of data from an enhanced surveillance scheme for toxoplasmosis in England and Wales. Between 2008 and 2012, 1824 cases were reported, with an average of 365 each year. There were 1109 immunocompetent cases, the majority presenting with lymphadenopathy, and 364 immunosuppressed cases, with central nervous system and systemic symptoms most frequently reported. There were also 190 pregnant and 33 congenital cases. Of the pregnant cases, 148 were asymptomatic (probably detected during screening), while 28 suffered a fetal loss or stillbirth. The enhanced surveillance system has led to an improvement in the detection of toxoplasmosis in England and Wales. However, numbers are still likely to be an underestimate, biasing towards the more severe infections.

Emerging infections are a potential risk during mass gathering events due to the congregation of large numbers of international travellers. To mitigate this risk for the London 2012 Olympic and Paralympic Games, a sentinel surveillance system was developed to identify clusters of emerging infections presenting as undiagnosed serious infectious illness (USII) in intensive care units (ICUs). Following a six month pilot period, which had begun in January 2011, the surveillance was operational for a further 18 months spanning the Games. The surveillance system and reported USII cases were reviewed and evaluated after this 18 month operational period including assessment of positive predictive value (PPV), timeliness, acceptability and sensitivity of the system. Surveillance records were used to review reported cases and calculate the PPV and median reporting times of USII surveillance. Sensitivity was assessed through comparison with the pilot period. Participating clinicians completed a five-point Likert scale questionnaire about the acceptability of surveillance. Between 11 July 2011 and 10 January 2013, 34 cases were reported. Of these, 22 remained classified as USII at the time of the evaluation, none of which were still hospitalised. No clusters were identified. The 22 USII cases had no association with the Games, suggesting that they represented the background level of USII in the area covered by the surveillance. This corresponded to an annualised rate of 0.39 cases/100,000 population and a PPV of 65%. Clinicians involved in the surveillance reported high acceptability levels. The USII surveillance model could be a useful public health tool in other countries and during mass gathering events for identifying potential clusters of emerging infections.

A new surveillance system was developed to detect possible new or emerging infections presenting as undiagnosed serious infectious illness (USII) for use during the London 2012 Olympic and Paralympic Games. Designated clinicians in sentinel adult and paediatric intensive care units (ICU/ PICUs) reported USII using an online reporting tool or provided a weekly nil notification. Reported cases were investigated for epidemiological links. A pilot study was undertaken for six months between January and July 2011 to evaluate the feasibility and acceptability of the system. In this six-month period, 5 adults and 13 children were reported by six participating units (3 ICUs, 3 PICUs). Of these 18 patients, 12 were reported within four days after admission to an ICU/PICU. Nine patients were subsequently diagnosed and were thus excluded from the surveillance. Therefore, only nine cases of USII were reported. No clustering was identified.On the basis of the pilot study, we conclude that the system is able to detect cases of USII and is feasible and acceptable to users. USII surveillance has been extended to a total of 19 sentinel units in London and the south-east of England during the London 2012 Olympic and Paralympic Games.

Emerging infections pose a constant threat to society and can require a substantial response, thus systems to assess the threat level and inform prioritization of resources are essential. A systematic approach to assessing the risk from emerging infections to public health in the UK has been developed. This qualitative assessment of risk is performed using algorithms to consider the probability of an infection entering the UK population, and its potential impact, and to identify knowledge gaps. The risk assessments are carried out by a multidisciplinary, cross-governmental group of experts working in human and animal health. This approach has been piloted on a range of infectious threats identified by horizon scanning activities. A formal risk assessment of this nature should be considered for any new or emerging infection in humans or animals, unless there is good evidence that the infection is neither a recognized human disease nor a potential zoonosis.

MUC7 encodes a small salivary mucin, previously called MG2, a glycoprotein with a putative role in facilitating the clearance of oral bacteria. The central domain of this glycoprotein was previously shown to comprise five or six tandemly repeated units of 23 amino-acids which carry most of the O-linked glycans. The polymorphism of these two allelic forms (MUC7*5 or MUC7*6) has been confirmed in this study in which we have analysed a large cohort of subjects (n = 375) of various ethnic origins. We have also identified a novel rare allele with eight tandem repeats (MUC7*8). MUC7*6 was the most common allele (0.78-0.95) in all the populations tested. The tandem repeat arrays of 22 MUC7*5 alleles and 34 MUC7*6 alleles were sequenced. No sequence differences were detected in any of the MUC7*6 alleles. Twenty-one MUC7*5 alleles sequenced lacked the 4th tandem repeat (structure TR12356), while one showed the structure TR12127. The structure of the MUC7*8 allele was TR12343456. Because of the known role of MUC7 in bacterial binding, and thus its potential involvement in susceptibility to chest disease we also tested MUC7 in our previously described series of Northern European atopic individuals with and without associated asthma. The MUC7*5 allele was rarer in the atopic asthmatics than in the atopic non-asthmatics (P = 0.014, OR for no asthma in atopic individuals 3.13, CI 1.01-6.10), and the difference in frequency between all asthmatics and all non-asthmatics was statistically significant (P = 0.009) while there was no difference between atopy and non-atopy (P = 0.199). In this study we also report the electrophoretic analysis of the MUC7 glycoprotein in saliva from individuals of different MUC7 genotype.

'Orphan' zoonotic diseases attract disproportionately low scientific and public health attention for the impact that they can have. This article pulls together information on their health burden in the UK from routine and enhanced data sources. These diseases are heterogeneous in nature; some have very low case numbers (e.g. hydatid disease), whilst others affect hundreds of patients each year (e.g. toxoplasmosis). The number of deaths attributed to orphan zoonoses is relatively low, and the majority recorded in this article were caused by toxoplasmosis. There is a clear issue of under-reporting and under-diagnosis in the data sets presented, and further work should be carried out to obtain more accurate estimates of the prevalence of zoonotic infections. Joint human and veterinary studies are especially important for these diseases.

At present, the European Council is debating whether the current national controls under the Pet Travel Scheme (PETS), which aims to prevent the introduction of rabies and tapeworms or live ticks and their associated diseases into the United Kingdom (UK), should be harmonized amongst European Union (EU) Member States. There is a strong case to support the retention of control measures on human health grounds. Although many are aware of the implications of rabies infection, few realize the risk to the UK population if current tick and tapeworm controls under PETS were to be removed. If this were to occur, there is a risk that a number of diseases of human health importance may be introduced and become established in the UK. Such diseases include alveolar echinococcosis, tick borne encephalitis, tularaemia and Mediterranean spotted fever; all of which are found in other EU Member States but do not occur in the UK. These four diseases are responsible for a significant burden of disease in Europe, and current national controls under PETS have been highly effective in so far preventing their introduction into the UK.

Influenza causes significant morbidity and mortality particularly in vulnerable population groups. Although vaccination is recommended as the primary method of preventing influenza, antiviral drugs may play a complementary role. The National Institute for Clinical Effectiveness (NICE) has recently published guidance on the use of anti-viral drugs in the treatment of influenza, and further guidance on their use for prophylaxis is expected later in the year. In anticipation of this guidance this paper reviews the evidence for the effectiveness of the prophylactic use of neuraminidase inhibitors. Results of this review show that neuraminidase inhibitors are effective in preventing laboratory-confirmed clinical influenza in healthy adults, both when used as post-exposure prophylaxis for close and household contacts, and as seasonal prophylaxis in the wider community. Direct evidence in the elderly and institutions is too limited to draw firm conclusions about their effectiveness in that setting. However it seems probable that neuraminidase inhibitors would also be effective in these groups.

Research from the USA suggests that cities with high mortality rates have high levels of hostility. Our aim was to replicate this research in English towns. A telephone questionnaire, based on the Cook-Medley hostility scale, was administered to random samples of adults in 10 English towns: five with high standardized mortality ratios (SMR) and five with low SMRs. The point estimate for the age-sex-weighted mean hostility score of high SMR towns was higher than that of low SMR towns (mean difference 0.2). However, the 95% confidence interval on the estimate included no difference between the two groups (-0.3-0.8). Our study does not confirm beyond doubt the findings of earlier research in the USA.

Most of the genes that encode epithelial mucins are highly polymorphic due to variations in the length of domains of tandemly repeated (TR) coding sequence, the part of the apomucin that is heavily glycosylated. We report here for the first time a difference in the distribution of MUC TR length alleles in chest disease. We examined the distribution of the length alleles of those MUC genes whose expression we have confirmed in the bronchial tree in an age- and sex-matched series of 50 pairs of atopic patients with and without asthma. There was no significant difference in the distribution of alleles of MUC1, MUC4, MUC5AC, and MUC5B. MUC2, however, showed a highly significant difference in distribution. The atopic, nonasthmatic individuals showed an allele distribution that was very different from all our other patient and control groups, this group showing a longer mean allele length. The observations suggest that longer MUC2 alleles may help protect atopic individuals from developing asthma, though the effect may be due to a linked gene. The biological significance of this variation with respect to susceptibility to asthma will merit further investigation, and it will also be important to substantiate this finding on an independent data set.
