Response of disease vectors, animal hosts, and pathogens to climate change may increase outbreaks of diseases like Rift Valley fever, which can cause severe symptoms and even death in livestock and people (Martin et al. 2008; Gould and Higgs 2009).
26, 34, 37 A study that assessed risk factors across four regions with summer outbreaks in Queensland found that the increased outbreak risk in the southern part of the state was associated with increased spring temperatures and early summer rainfall.
Survival analysis Cox regression models using an outbreak of gastroenteritis as the endpoint were fitted to identify institutional and operational attributes related to increased outbreak rates at the level of the care unit.
These new NoV strains have often, but not always, led to increased outbreak activity (8, 10, 13, 14 ).
Colder lake temperature and increased river flow were associated with an increased outbreak risk, suggesting a source-water reservoir for Norovirus.
The risk of increasing outbreak events in such areas would be closely related to the genetic ability to gregarise of the populations of interest.
Three types of outbreaks were used, each representing various types of naturally occurring events: log normal, a rapidly increasing outbreak; inverted log normal, a slowly starting outbreak; and a single-day spike.
This fact increases outbreak investigation expense, thus norovirus testing and confirmation should be more readily available to microbiology laboratories enhancing detection of sporadic cases that are now under detected.
Doctors and government officials fear the situation will only further deteriorate in coming days with increasing outbreaks of cholera, malaria and typhoid.
