Was priority setting included in the Canadian COVID-19 pandemic planning and preparedness? A comparative analysis of COVID-19 pandemic plans from eight provinces and three territories.

BACKGROUND: Variation in priorities during pandemic planning among the federal, provincial and territorial jurisdictions are thought to have impacted Canada's ability to effectively control the spread of the COVID-19 virus, and protect the most vulnerable. The potential influence of diverse and divergent political, cultural, and behavioural factors, regarding inclusion of priority setting (PS) in pandemic preparedness planning across the country is not well understood. This study aimed to examine how the Canadian federal, provincial and territorial COVID-19 pandemic preparedness planning documents integrated PS. METHODS: A documentary analysis of the federal, eight provincial, three territorial COVID-19 preparedness and response plans. We assessed the degree to which the documented PS processes fulfilled established quality requirements of effective PS using the Kapiriri & Martin framework. RESULTS: While the federal plan included most of the parameters of effective PS, the provinces and territories reflected few. The lack of obligation for the provinces and territories to emulate the federal plan is one of the possible reasons for the varying inclusion of these parameters. The parameters included did not vary systematically with the jurisdiction's context. CONCLUSION: Provinces could consider using the framework of the federal plan and the WHO guidelines to guide future pandemic planning. Regular evaluation of the instituted PS would provide a mechanism through which lessons can be harnessed and improvement strategies developed. Future studies should describe and evaluate what PS mechanisms were implemented.

Genetic structure and population dynamics of Xanthomonas axonopodis pv. manihotis in Colombia from 1995 to 1999.

Restriction fragment length polymorphisms (RFLPs) were used to study the population genetics and temporal dynamics of the cassava bacterial pathogen Xanthomonas axonopodis pv. manihotis. The population dynamics were addressed by comparing samples collected from 1995 to 1999 from six locations, spanning four different edaphoclimatic zones (ECZs). Forty-five different X. axonopodis pv. manihotis RFLP types or haplotypes were identified between 1995 and 1999. High genetic diversity of the X. axonopodis pv. manihotis strains was evident within most of the fields sampled. In all but one site, diversity decreased over time within fields. Haplotype frequencies significantly differed over the years in all but one location. Studies of the rate of change of X. axonopodis pv. manihotis populations during the cropping cycle in two sites showed significant changes in the haplotype frequencies but not composition. However, variations in pathotype composition were observed from one year to the next at a single site in ECZs 1 and 2 and new pathotypes were described after 1997 in these ECZs, thus revealing the dramatic change in the pathogen population structure of X. axonopodis pv. manihotis. Disease incidence was used to show the progress of cassava bacterial blight in Colombia during the 5-year period in different ecosystems. Low disease incidence values were correlated with low rainfall in 1997 in ECZ 1.
