4) If person i is not infected by the end of the outbreak, the likelihood function for person i is the product of the probabilities of person i escaping infection up to the last day of observation.
According to our results, if the virus had been introduced to Scotland prior to detection of the outbreak, the likelihood of pre-detection spread via livestock movement would have been at its highest.
However, with the propensity of the El Tor biotype to cause prolonged and recurrent outbreaks, high likelihood of becoming endemic, ability to be carried asymptomatically, association with case-fatality rates of 2%6%% among patients who receive clinical care during complex emergencies, and availabilty of improved oral cholera vaccines, is it time to rethink our plans?
(2) How has the occurrence and duration of bark beetle outbreak influenced the likelihood of subsequent burning in these two landscapes?
In addition, both the short disease course of 5 20 days and high contagiousness implied that highly virulent strains of the PRRSV might be involved in this PRRS outbreak, indicating the likelihood of some important mutation of these strains.
No new cases have been reported in humans or animals since the outbreak, despite the likelihood that some surviving infected animals have been kept alive by individual or commercial owners.
Analysis of data from measles outbreaks shows that likelihood scores are highest for models that allow a flexible degree of transmission heterogeneity.
According to analysis conducted in 2005 by Marc Levy, Charles Vorosmarty and Nils Petter Gleditsch: "...at the global scale, there is a highly significant relationship between rainfall deviations and the likelihood of outbreak of a high-intensity internal war.
To determine the likelihood of outbreak we carried out 1000 simulations for each combination of parameter settings.
The model shows that the likelihood for outbreak increases with heritability and the frequency of favourable years.
