Lessons learned from the 2009-2010 H1N1 outbreak for the management of the 2013 silent polio outbreak.

ABSTRACT:

Background

The Israeli Ministry of Health (MoH) encountered two substantial outbreaks during the past decade: the H1N1 swine flu outbreak during 2009-2010 and the silent polio outbreak during 2013. Although both outbreaks share several similar characteristics, the functioning of the Israeli MoH was different for each case. The aim of this study was to identify factors that contributed to the change in the MoH response to the polio outbreak in light of the previous 2009-2010 H1N1 outbreak.

Methods

We conducted a qualitative research using semi-structured interviews with 18 Israeli policymakers from the MoH, relevant specialists and politicians. Each interview was transcribed and a thematic analysis was conducted independently by two researchers.

Results

Three main themes were found in the interview analysis, which reflect major differences in the MoH management policy during the polio outbreak. 1) clinical and epidemiological differences between the two disease courses, 2) differences in the functioning of the MoH during the outbreaks, 3) differences in the risk communication strategies used to reach out to the local health community and the general public. Most interviewees felt that the experience of the 2009-2010 H1N1 outbreak which was perceived as unsuccessful, fueled the MoH engagement and proactiveness in the later polio outbreak.

Conclusion

These findings highlight the importance of learning processes within health care organizations during outbreaks and may contribute to better performance and higher immunization rates.

Project description:Polio eradication is an extraordinary globally coordinated health program in terms of its magnitude and reach, leading to the elimination of wild poliovirus (WPV) in most parts of the world. In 2013, a silent outbreak of WPV was detected in Israel, a country using an inactivated polio vaccine (IPV) exclusively since 2005. The outbreak was detected using environmental surveillance (ES) of sewage reservoirs. Stool surveys indicated the outbreak to be restricted mainly to children under the age of 10 in the Bedouin population of southern Israel. In order to curtail the outbreak, a nationwide vaccination campaign using oral polio vaccine (OPV) was conducted, targeting all children under 10.A transmission model, fitted to the results of the stool surveys, with additional conditions set by the ES measurements, was used to evaluate the prevalence of WPV in Bedouin children and the effectiveness of the vaccination campaign. Employing the parameter estimates of the model fitting, the model was used to investigate the effect of alternative timings, coverages and dosages of the OPV campaign on the outcome of the outbreak.The mean estimate for the mean reproductive number was 1.77 (95 % credible interval, 1.46-2.30). With seasonal variation, the reproductive number maximum range was between zero and six. The mean estimate for the mean infectious periods was 16.8 (8.6-24.9) days. The modeling indicates the OPV campaign was effective in curtailing the outbreak. The mean estimate for the attack rate in Bedouin children under 10 at the end of 2014 was 42 % (22-65 %), whereas without the campaign the mean projected attack rate was 57 % (35-74 %). The campaign also likely shortened the duration of the outbreak by a mean estimate of 309 (2-846) days. A faster initiation of the OPV campaign could have reduced the incidence of WPV even if a lower coverage was reached, at the risk of prolonging the outbreak.OPV campaigns are essential for interrupting WPV transmission, even in a developed country setting with a high coverage of IPV. In this setting, establishing ES of WPV circulation is particularly crucial for early detection and containment of an outbreak.
