Travelers With Chikungunya Virus Infection Returning to Northwest Italy From the Caribbean and Central America During June-November 2014

Chikungunya virus (CHIKV) has recently emerged in the Caribbean. In Italy, CHIKV vector is documented in the Po river valley; therefore, a risk for autochthonous outbreaks is present. We report a case series of seven imported CHIKV infections in travelers returning from the Caribbean and Latin America occurring between June and November 2014, in the area of Turin, Northwest Italy, 3 years after the last imported cases were reported. These cases are a reminder of the need to always consider CHIKV infection in travelers from these epidemic areas as well as the importance of a prompt diagnosis.

Risk perception about zoonoses in immigrants and Italian workers in Northwestern Italy

OBJECTIVE

To assess factors associated with a low risk perception of zoonoses and to identify the gaps in knowledge about transmission and prevention of zoonoses in immigrant and Italian workers.

METHODS

A cross-sectional study with 175 workers in the agro-livestock and agro-food industry in Piemonte, Italy, was carried out. Data were collected with a semi-structured questionnaire based on knowledge, attitudes and practices (KAP) survey. We calculated proportions and used chi-square tests and odds ratios to assess associations. Eight individual interviews with key informants on immigration and public health in Piemonte were carried out.

RESULTS

Participants were 82 (47%) Italians and 93 (53%) immigrants. Immigrants were from Romania, Morocco, Albania, India, China, Argentina, Peru, Macedonia, Ivory Coast, Ukraine and Colombia. The study revealed significant differences in risk perception at work (p = 0.001). We found associations between "not having correct knowledge about zoonoses" and the following variables: i. "being immigrant" OR = 4.1 (95%CI 1.7;9.8 p ≤ 0.01); ii. "working in the livestock industry" OR = 2.9 (95%CI 1.2;15.4 p = 0.01); and iii. "being an unqualified worker" OR = 4.4 (95%CI 2.9;15.4 p ≤ 0.01). Another strong association was found between being immigrant and having a low job qualification OR = 6.7 (IC95% 2.9 - 15.4 p ≤ 0.01). Asian immigrants were the group with the highest frequency of risky behaviours and the lowest level of knowledge about zoonoses.

CONCLUSIONS

Our results indicate that there were differences in risk perception of zoonoses between the groups participating in our study. These results suggest that immigrant status can be considered a risk factor for having lower risk perception and lower level of knowledge of zoonoses at work. There is a relationship between this specific knowledge of zoonoses and lack of training and instruction among migrant populations. Our results stress the need for developing education programs on zoonoses prevention among the immigrant population in Piemonte, Italy.

The effectiveness and safety of hepatitis A vaccine: a systematic review

We report on the conduct of a systematic review to assess the efficacy and the safety of hepatitis A vaccines in adults and children. We identified, retrieved, and assessed all trials evaluating the effects of hepatitis A vaccines on prevention of cases of hepatitis A, death from hepatitis A, and assessing nature and frequency of adverse events. We included eight randomised trials, four containing efficacy outcomes, three containing only safety outcomes and a single study containing efficacy and adverse events outcomes. Combined inactivated vaccine effectiveness was 86% (95% CI: 63-95%). Combined attenuated vaccine effectiveness was 95% (95% CI: 81-99%). Inactivated vaccine effectiveness in the prevention of HAV secondary cases, compared to non-intervention was 82% (95% CI: 23-96%). Safety profile of vaccines was similar to that of their comparators. Despite poor design and reporting of trials, we found convincing evidence of the effectiveness and safety of inactivated HAV vaccines.

[Case-control study of hemo-lymphopoietic neoplasms and exposure to pesticides in western Liguria]

The association between hematolymphopoietic cancers and occupational exposures to pesticides is being examined in a population based case-control study. 228 cases diagnose aged 20-74 years and 140 controls between 1/1/1990-31/12/1993 were eligible for the study in the west Liguria area. 163 cases and 109 controls were interviewed regarding use of pesticides and other possible risk factors and confounding variables. Expert agronomists assessed the job exposure to pesticides using the informations from questionnaires and the job-matrices.

[Herbicides and neoplasms of the hemolymphopoietic system]

The study is a population-based case-control study on hematolymphopoietic tumors, conducted in west Liguria with high prevalence of exposure to chemicals suspected (about 10%) of increasing the risk of leukaemias or lymphomas and multiple myeloma (pesticides). Cases and control were identified and confirmed during the period 1/1/1990 through 31/12/1993. Cases are identified through periodic contacts with the Pathology, or Hematology or other relevant Department of the Hospitals of west Liguria and Genoa town or University of Genoa where patients living in these area are referred for hematolymphopoietic malignancies. Controls are a random sample of the general population living in each area (using the demographic health archives). The range of the age is 20-74. After identification each case or control is contacted to have his consent to the interview near the home. Informations collected using a most completed questionnaire regard drinking and smoking habit, the addresses and the conditions of the homes where spending the life, particularly hobbies about exposure of pesticides and/or solvents, more important pathological events on the life and the occupational exposure. Actually we are in the phase of identification of cases and controls.
