Initial risk perception and feeling of preparedness of primary care physicians regarding the COVID-19 pandemic in Belgium, France and Spain in February 2020.

BACKGROUND: The knowledge of risk perceptions in primary care could help health authorities to manage epidemics. METHODS: A European multi-center cross-sectional study was conducted in France, Belgium and Spain to describe the perceptions, the level of anxiety and the feeling of preparedness of primary healthcare physicians towards the COVID-19 infection at the beginning of the pandemic. The factors associated with the feeling of preparedness were studied using multivariate logistic regressions. RESULTS: A total of 511 physicians participated to the study (response rate: 35.2%). Among them, only 16.3% (n=82) were highly anxious about the pandemic, 50.6% (n=254) had the feeling to have a high level of information, 80.5% (n=409) found the measures taken by the health authorities suitable to limit the spread of COVID-19, and 45.2% (n=229) felt prepared to face the epidemic. Factors associated with feeling prepared were: being a Spanish practitioner (adjusted OR=4.34; 95%CI [2.47; 7.80]), being a man (aOR=2.57, 95%CI [1.69; 3.96]), finding the measures taken by authorities appropriate (aOR=1.72, 95%CI [1.01; 3.00]) and being highly informed (aOR=4.82, 95%CI [2.62; 9.19]). CONCLUSIONS: Regarding the dramatic evolution of the pandemic in Europe in the weeks following the study, it appears that information available at this time and transmitted to the physicians could have given a wrong assessment of the spread and the severity of the disease. It seems essential to better integrate the primary care physicians into the information, training and protection channels. A comparison between countries could help to select the most effective measures in terms of information and communication.

[Interest of a geostatistical approach to analyze the geographical disparities in human papillomavirus vaccine coverage in France]. / Intérêt d'une approche géostatistique pour analyser les disparités géographiques de la couverture vaccinale contre les papillomavirus humains en France.

BACKGROUND: The use of geostatistical methods remains rare in health studies. In order to assess the usefulness of the geostatistical approach in epidemiology, we chose to apply these methods to the vaccination coverage rate (VCR) against human papillomavirus (HPV) in France. Indeed, HPV vaccine coverage remains low in France and geographical disparities are sizable. The objective of this study was to identify the socioecological factors that may explain these geographical variations. METHODS: Sociological, economic and behavioral data for 2016 have been gathered (demographics and public health database, web and social networks) and were correlated with the HPV VCR vaccine coverage over the French territory. Homogeneous geographical areas defined by strong correlations for groups of variables were selected. In each homogeneous area, principal component analysis was performed and a geostatistical approach provided an estimate predicting vaccine coverage at a given scale. RESULTS: HPV VCR spatial variations in France cannot be fully explained by a single model. In urban areas, a low rate of HPV VCR is preferentially associated with unfavorable socioeconomic factors (poverty, unemployment, immigration). In rural areas, HPV VCR is preferentially associated with sociocultural factors (socio-professional categories, education level, interest in alternative medicines the anti-vaccine movement). Two secondary geographical areas were defined: the Île-de-France region and 12 departments in northeastern France. In the Île-de-France region, the association with the economic factors one again appears as in urban areas in general. The northeasteran departments represent a particular case insofar as HPV VCR is relatively high, notwithstanding economic poverty indicators. CONCLUSION: Geostatistical modeling successfully identifies new potential explanations for HPV VCR geographical disparities in France. These results could help to adapt or develop future vaccination programs in specific areas by taking into account the sociological, economic and behavioral characteristics of their populations.

The role of alternative and complementary medical practices in vaccine hesitancy among nurses: A cross-sectional survey in Brittany.

INTRODUCTION: Given today's increasing calling into question of vaccination, we have studied possible connections between alternative and complementary medical practices (CAM) and vaccine hesitancy (VH) among nurses. METHOD: Ours was a cross-sectional study by self-administered online questionnaire addressed to a panel of nurses in Brittany. After adjustment for other proximal and distal determinants of VH, we examined the impact of CAM use. RESULTS: Multivariate logistic regressions confirmed the existence of a link between CAM and VH. While trust in medical institutions seems to have an important role, CAM use appears largely independent of VH. CONCLUSION: Association between CAM and VH in nurses raises the question not only of their training with respect to these alternative practices, but also of the role of medical institutions in the training of practitioners availing themselves of the latter.

Need for integrative thinking to fight against emerging infectious diseases. Proceedings of the 5th seminar on emerging infectious diseases, March 22, 2016 - current trends and proposals.

We present here the proceedings of the 5th seminar on emerging infectious diseases, held in Paris on March 22nd, 2016, with seven priority proposals that can be outlined as follows: encourage research on the prediction, screening and early detection of new risks of infection; develop research and surveillance concerning transmission of pathogens between animals and humans, with their reinforcement in particular in intertropical areas ("hot-spots") via public support; pursue aid development and support in these areas of prevention and training for local health personnel, and foster risk awareness in the population; ensure adapted patient care in order to promote adherence to treatment and to epidemic propagation reduction measures; develop greater awareness and better education among politicians and healthcare providers, in order to ensure more adapted response to new types of crises; modify the logic of governance, drawing from all available modes of communication and incorporating new information-sharing tools; develop economic research on the fight against emerging infectious diseases, taking into account specific driving factors in order to create a balance between preventive and curative approaches.

General practitioners and vaccination of children presenting with a benign infection.

PURPOSE: To assess the self-reported vaccination behavior of general practitioners (GPs) when asked whether they would recommend the vaccination of a child presenting with a febrile uncomplicated common cold. METHODS: We performed a cross-sectional survey in 2014 on a national sample of GPs. GPs were randomly assigned to one of eight clinical vignettes, all describing a child presenting with an uncomplicated febrile common cold, but differing by age (4 or 11 months), temperature (38°C or 39°C), and the mother's emotional state (calm or worried). GPs were asked whether they would recommend immediate vaccination of the child with a hexavalent vaccine (diphtheria, tetanus, pertussis, poliomyelitis, Haemophilus influenzae type b, and hepatitis B), or postpone it. We investigated the relation between the GPs' recommendation to vaccinate, the clinical vignette's variables, and the GPs' perceptions, attitudes, and practices toward vaccination in a multivariate model. RESULTS: Among the 1582 participating GPs, 6% recommended immediate vaccination. This behavior was more frequent with a temperature of 38°C rather than 39°C (10% vs. 3%, P<0.001). GPs who felt comfortable giving explanations about vaccine safety were more likely to recommend immediate vaccination of the febrile child (P=0.045), but none of the other GPs' characteristics were associated with their vaccination behavior. CONCLUSIONS: Almost all GPs postponed the hexavalent vaccination of the febrile child presenting with an uncomplicated viral disease; fever being the major factor affecting their decision. More research is needed on vaccination responses in sick children, as well as clearer guidelines.

[How do we catch flu? Beliefs in France in 2010]. / Comment attrape-t-on la grippe ? Les croyances des Français en 2010.

AIMS: Our goals were to describe beliefs held by French people concerning the contagiosity of influenza and analyze the relationship of these beliefs with vaccination against seasonal flu. METHODS: A subsample (4749 people aged 15-79) of the Health Barometer 2010 responded to questions dealing with influenza. Responses were analyzed using clustering analysis and logistic regression. RESULTS: Overall, observed beliefs were quite good, but also socially differentiated. 'False' beliefs were more frequent among people with a lower socioeconomic status. Those who overestimated the contagiosity of influenza were less likely to have been vaccinated against seasonal influenza in 2008. CONCLUSIONS: The beliefs analyzed here were associated with vaccination behaviors. 'False' beliefs may be difficult to change as they are nevertheless coherent. These beliefs also exhibit social inequalities that should be taken into account when determining preventive measures.

Trends in influenza vaccination behaviours--results from the CoPanFlu cohort, France, 2006 to 2011.

Controversies over the effectiveness and safety of the pandemic influenza A(H1N1)pdm09 vaccine in 2009/10 may have altered the influenza vaccination coverage in France after the pandemic season. The purpose of this study was to determine whether the pandemic affected seasonal influenza vaccination behaviours in the general population by analysing vaccination behaviours from 2006/07 to 2011/12 among the 1,451 subjects of the Cohort for Pandemic Influenza (CoPanFlu) France.We found that vaccination behaviours in 2010/11 and 2011/12 significantly differed from behaviours before the pandemic, with the notable exception of the targeted risk groups for seasonal influenza-related complications. Among the population with no risk factors,the post-pandemic influenza vaccine coverage decreased, with people aged 15 to 24 years and 45to 64 years being most likely to abandon vaccination.Therefore, this study documents a moderate negative effect of the 2009/10 pandemic episode on vaccination behaviours in the French metropolitan population that was apparent also in the following two seasons.Moreover, it does not exclude that the general trend of reduced vaccination has also affected certain targeted groups at high risk for complications.

Dramatic change in public attitudes towards vaccination during the 2009 influenza A(H1N1) pandemic in France.

We investigated the potential impact of the 2009 influenza A(H1N1) pandemic on attitudes towards vaccination among people aged 18 to 75 years and living in metropolitan France. We used data from three national telephone surveys conducted on representative samples in 2000, 2005 and 2010 (n=12,256, n=23,931, n=8,573 respectively). In France, unfavourable attitudes towards vaccination in general dramatically increased from 8.5% in 2000 and 9.6% in 2005 to 38.2% in 2010. In 2010, among respondents who held unfavourable attitudes towards vaccination, 50% mentioned specifically their opposition to the influenza A(H1N1) vaccine. The sociodemographic profile associated with these attitudes also changed greatly. In particular, unfavourable attitudes towards vaccination in general became significantly more frequent among less educated people in 2010. These attitudes were also correlated with vaccination behaviours. For example, parents who were unfavourable towards vaccination in general were more likely to report that they had at least one child who did not get the measlesmumps- rubella vaccine. As this shift in attitude may have a significant impact on future vaccination coverage, health authorities should urgently address the vaccine confidence gap.

The moth Hylesia metabus and French Guiana lepidopterism: centenary of a public health concern.

The females of the moths Hylesia metabus have their abdomens covered by urticating hairs looking like micro-arrows and causing a puriginous dermatitis to humans known as "papillonite" in French Guiana and also called yellowtail moth dermatitis or Caripito itch. The densities of the moths show great seasonal and annual variations depending on mechanisms mostly unknown. When H. metabus infestations occur, numerous cases of dermatologic manifestations are reported from people living near the mangrove swamps where the moths are developing. One hundred years after the first "papillonite" epidemic reported from French Guiana in 1912, the data presented herein summarize the actual state of knowledge on H. metabus biology and ecology and on the lepidopterism. Some recommendations are proposed for the surveillance and warning systems of H. metabus infestations and to avoid contact with the moths. Research priorities are suggested to improve the control against this problem emerging between nuisance and public health.

Population response to the risk of vector-borne diseases: lessons learned from socio-behavioural research during large-scale outbreaks.

Vector-borne infectious diseases, such as malaria, dengue, chikungunya, and West Nile fevers are increasingly identified as major global human health threats in developing and developed countries. The success or failure of vector control rests mainly on the nature and scale of the behavioural response of exposed populations. Large-scale adoption of recommended protective behaviour represents a critical challenge that cannot be addressed without a better understanding of how individuals perceive and react to the risk of infection. Recently, French overseas territories faced large-scale outbreaks: an epidemic of chikungunya fever in La Re' union and Mayotte (2005-2006) and four successive outbreaks of dengue fever in one Caribbean island, Martinique (1995-2007). To assess how these populations perceived and responded to the risk, and how the nature and scale of protection affected their clinical status, socio-epidemiological surveys were conducted on each island during the outbreaks. These surveys address three crucial and interconnected questions relevant to the period after persons infected by the virus were identified: which factors shape the risk of acquiring disease? Which socio- demographic characteristics and living conditions induce a higher likelihood of infection? What is the impact of risk perception on protective behaviours adopted against mosquito bites? Grounded on the results of these surveys, a general framework is proposed to help draw out the knowledge needed to reveal the factors associated with higher probability of infection as an outbreak emerges. The lessons learnt can inform health authorities' efforts to improve risk communication programmes, both in terms of the target and content of messages, so as to explore new strategies for ensuring sustainable protective behaviour. The authors compare three epidemics of vector-borne diseases to elucidate psychosocial factors that determine how populations perceive and respond to the risk of infectious disease.
