The experiences of using polio outbreak simulation exercises to strengthen national outbreaks preparedness and response plans in sub-Saharan Africa.

INTRODUCTION: globally, by 2020 the paralytic poliomyelitis disease burden decreased to over 99% of the reported cases in 1988 when resolution 41.8 was endorsed by the World Health Assembly (WHA) for global polio eradication. It is clearly understood that, if there is Wild Poliovirus (WPV) and circulating Vaccines Derived Poliovirus (cVDPV) in the world, no country is safe from polio outbreaks. All countries remain at high risk of re-importation depending on the level of the containment of the types vaccine withdrawn, the laboratory poliovirus isolates, and the population immunity induced by the vaccination program. In this regard, countries to have polio outbreak preparedness and response plans, and conducting the polio outbreak simulation exercises for these plans remain important. METHODS: we conducted a cross-section qualitative study to review to 8 countries conducted polio outbreak simulation exercises in the East and Southern Africa from 2016 to 2018. The findings were categorized into 5 outbreak response thematic areas analyzed qualitatively and summarized them on their strengths and weaknesses. RESULTS: we found out that, most countries have the overall technical capacities and expertise to deal with outbreaks to a certain extent. Nevertheless, we noted that the national polio outbreak preparedness and response plans were not comprehensive enough to provide proper guidance in responding to outbreaks. The guidelines were inadequately aligned with the WHO POSOPs, and IHR 2005. Additionally, most participants who participated in the simulation exercises were less familiar with their preparedness and response plans, the WHO POSOPs, and therefore reported to be sensitized. CONCLUSION: we also realized that, in all countries where the polio simulation exercise conducted, their national polio outbreak preparedness and response plan was revised to be improved in line with the WHO POSOPs and IHR 2005. we, therefore, recommend the polio outbreak simulation exercises to be done in every country with an interval of 3-5 years.

Reducing resistance to polio immunisation with free health camps and Bluetooth messaging: An update from Kaduna, Northern, Nigeria.

Since 1997, the Global Polio Eradication Initiative has sponsored regular door-to-door polio immunisation campaigns in northern Nigeria. On 30 July 2015, the country was finally declared poliofree, a hard won success. At various times, polio eradication has been threatened by rumours and community tensions. For example, in 2003, local Imams, traditional leaders and politicians declared a polio campaign boycott, due to the concerns about the safety of the polio vaccine. Although the campaigns resumed in 2004, many parents continued to refuse vaccination because of the persistence of rumours of vaccine contamination, and anger about the poor state of health services for conditions other than polio. To address this, UNICEF and Nigerian Government partners piloted two interventions: (1) mobile 'health camps' to provide ambulatory care for conditions other than polio and (2) an audiovisual clip about vaccine safety and other health issues, shareable on multimedia mobile phones via Bluetooth pairing. The mobile phone survey found that Bluetooth compatible messages could rapidly spread behavioural health messages in low-literacy communities. The health camps roughly doubled polio vaccine uptake in the urban ward where it was piloted. This suggests that polio eradication would have been accelerated by improving primary health care services.
