In effect, we have made the tacit assumption that distribution of foods in the subset of outbreaks in which a vehicle was identified is representative of the complete population of outbreaks.
The population of the outbreak area was approximately one million.
We found significantly fewer alleles (−55%) and a lower heterozygosity (−26%) in CSE Europe (complete data set) than in Pennsylvania, the putative source population of this outbreak in north-eastern America (Wilcoxon's signed rank tests, P = 0.018 and 0.036 for AR and H, respectively).
Elimination targets include 95% vaccination coverage with 2 doses of measles virus containing vaccine (MVCV), an incidence of <1 measles case per million population, 80% of outbreaks associated with <10 cases, and transmission of indigenous or imported measles virus for no longer than 12 months in a defined region (2 ).
There is no mention of cycle phases other than the crash phase (O. brumata), nor mention of successive population cycles or of outbreak waves (cf. Tenow 1972 ; Tenow et al. 2007 ) only of "more complex spatial patterns".
Two major findings are that the outbreaks of winter moth tend to lag those of autumnal moth by one to two years, and waves of population outbreaks of both species occur from east to west across Fennoscandia with a ten-year periodicity (Tenow 2013).
Covariates included 1) vancomycin reduction alone vs. concomitant implementation of other VRE control interventions, 2) ward-specific vs. hospital-wide interventions, 3) severity of illness of the study population, 4) outbreak status of the institution or ward(s) under investigation, 5) type of quasi-experimental design and 6) duration of intervention.
Large-scale population outbreaks of the crown-of-thorns starfish (COTS, Acanthaster spp).
Other environmental pressures on the reef and its ecosystem include runoff, climate change accompanied by mass coral bleaching, and cyclic population outbreaks of the crown-of-thorns starfish.
The SurvNet system appears to capture far more outbreaks per population than published collections of outbreak reports in other countries.
