“…These results were consistent with the findings of studies from other industrialized countries [29–35]. A Canadian study found that the most commonly reported reason to opt out of influenza vaccination in people aged ≥60 years and people with chronic medical conditions were low perceived susceptibility to influenza or low perceived severity of the infection, as well as a lack of interest, and lack of time or information [29]. Another study found that in Germany, forgetfulness was a primary barrier to influenza vaccination [30].…”

BackgroundOlder adults and individuals with underlying chronic diseases are at increased risk of developing influenza-related complications and are target groups for seasonal influenza vaccination in many countries. In Germany, an annual national information campaign is conducted to increase influenza vaccination uptake in the target groups. However, data are lacking on knowledge and attitudes toward influenza vaccination among older adults and those with chronic diseases. The present study aimed to (i) estimate influenza vaccination uptake for the 2012/13 and 2013/14 seasons, (ii) assess knowledge and attitudes about influenza vaccination, and (iii) identify factors associated with vaccination uptake in two risk groups.MethodsBetween March and June 2014, we conducted a nationwide cross-sectional survey in adults (≥18 years) living in Germany using computer-assisted telephone interviewing. We calculated weighted vaccination coverage rates in two at-risk groups. Group 1 comprised participants aged 18–59 years with underlying chronic diseases. Group 2 comprised participants aged 60+, irrespective of underlying disease. We used univariate and multivariable logistic regression analyses to identify associations between influenza vaccination uptake and sociodemographic characteristics, and to evaluate attitudes and knowledge.ResultsIn total, 1,519 interviews were conducted. Seasonal influenza vaccination uptake in people with underlying chronic diseases aged 18–59 years was 24 % in 2012/2013 and 23 % in 2013/2014. In older adults, uptake was 50 % and 49 % in 2012/13 and 2013/14 respectively. There were considerable vaccination-related knowledge gaps among respondents. For example, about half of the participants who aged ≥60 years and/or suffered from underlying chronic diseases believed that influenza vaccination could cause influenza. The most commonly stated reasons for not being immunized were mistrust of the vaccination (22 %) and the perception that influenza is not dangerous (21 %). For both groups, vaccination uptake was independently associated with sex, perceived severity of influenza, perceived vaccination effectiveness, and the perceived likelihood or severity of vaccination side effects. For older adults, additional factors influencing vaccination uptake were age, underlying chronic diseases, and recent advice through physician consultation.ConclusionsInfluenza vaccination coverage rates in Germany remain low. Individual perceptions regarding harms and benefits are crucial in the decision-making process. Communication strategies should focus on improving understanding and perception of personal risks arising from the disease and the vaccination.

“…In the study published by Ho et al (2013), 51% of surveyed healthcare professionals had more than 10 years of experience. The respondents in this study also had fewer years of experience than those investigated by Dubé et al (2011) in Quebec. In fact, 65% of health professionals investigated by Dubé et al (2011) had at least 15 years of experience.…”

Dengue has become a major public health concern in Cote d'Ivoire since 2010. In malaria endemic countries, such as Cote d'Ivoire, healthcare workers often confuse dengue with other tropical fevers, such as malaria. However, to control dengue fever, healthcare workers must be knowledgeable about this disease. A cross-sectional study was conducted on 400 healthcare workers' knowledge, attitude, and practices in relation to dengue from 3 rd September, 2014 to 20 th March, 2015 in Abidjan and its suburbs. Logistic analyses with stepwise selection were performed to explain the relationship between the dependent variable (practices) and the main explicative variable (knowledge). The distribution of participant healthcare workers by health facility showed that 55% worked in reference health facilities. Among the 340 participants, 70 (21%) had a good knowledge of dengue fever, while 71 (21%) had good diagnostic practices. The logistical analysis with stepwise selection showed that practices were explained by knowledge (adjusted OR (aOR) = 2.69; p = 0.004), gender (aOR = 1.88; p = 0.036), occupation (aOR = 0.37; p = 0.003) and epidemic risk perception (aOR = 2.59; p = 0.001). The study shows that nurses had better practices in term of dengue diagnosis compared with medical doctors. Similarly, healthcare workers who had good knowledge of dengue fever also had good practices. However, there is a great need for healthcare workers to be trained on how to detect dengue disease.

“…4 However, influenza vaccine coverage in these target groups is low and still does not reach the national objective of 80% for the group of adults aged 18-59 with 1 chronic condition. 5,6 According to the latest available data in Quebec, 57% of adults aged 60 and 33% of adults aged 18-59 and suffering from a chronic medical condition were vaccinated against influenza during the 2013-2014 season. 5,6 This suboptimal vaccination coverage is problematic and highlights the need for effective strategies to increase influenza vaccination.…”
