maximum likelihood - In statistics, maximum likelihood estimation (MLE) is a method of estimating the parameters of an assumed probability distribution, given some observed data. This is achieved by maximizing a likelihood function so that, under the assumed statistical model, the observed data is most probable (https://en.wikipedia.org/wiki/Maximum_likelihood_estimation).

In the context of outbreaks and epidemiology, "virulence" and "severity" are related but distinct concepts.
Virulence refers to the ability of a pathogen to cause disease or harm to its host. It often encompasses factors such as how easily the pathogen can spread, how quickly it can replicate within the host, and the overall impact it has on the host's health. In epidemiological terms, virulence can influence the rate and extent of an outbreak by affecting factors such as transmission dynamics and the severity of illness experienced by infected individuals.
Severity, on the other hand, refers to the seriousness or intensity of the disease once it has infected a host. It encompasses factors such as the symptoms experienced, the duration of illness, the likelihood of complications or death, and the overall burden on healthcare systems. Severity can vary widely depending on factors such as the specific strain of the pathogen, the characteristics of the host population, and the availability of medical resources.
In summary, while both virulence and severity are important considerations in understanding and managing outbreaks, they represent different aspects of the disease process. Virulence relates to the pathogen's ability to cause harm, while severity pertains to the impact of the disease on infected individuals and populations.
