PT 33 was, however, an effective marker for the most prevalent outbreak type.
We determined that NoV GI was more prevalent in foodborne outbreaks than in outbreaks in health care and community settings, which is consistent with previous studies that reported that GI is more frequently observed in foodborne NoV outbreaks than in outbreaks involving person-to-person transmission (2, 3 ).
Epidemics of cholera are observed in southern Asia, Africa, and South America and are still prevalent as seasonal outbreaks [16].
Similarly, in Southeast Asia, where serotypes O and A are prevalent every year, outbreaks due to Asia 1 have been reported only sporadically in the past 10 years; a recent gap in reporting occurred between 2002 and 2005 (Table; Technical Appendix Table 1).
In Japan, GII.17_2014 was a prevalent cause of NoV outbreaks from December 2014 onwards, becoming the predominant genotype in March 2015, but the total number of NoV outbreaks during this season was lower than that of previous years [ 13].
DENV-2 was the most prevalent serotype in several outbreaks in the Americas [ 6] and was epidemiologically classified as the most relevant serotype worldwide due to its association with the highest number of intense outbreaks, followed in sequence by DENV-3, DENV-1, and DENV-4 [ 25].
The results showed that two distinct P1 types (type I and type II) were prevalent in this MP outbreak.
Rainfall levels below 75 mm were more prevalent during the annual outbreak transmission season of HFMD, while rainfall above this threshold dominated in the wet season.
In general, outbreaks are more prevalent on poorer quality sites and where there are large populations of overly-dense, older trees (Fettig et al. [2007]).
As bark beetle outbreaks become increasingly prevalent in western landscapes, longer-term biogeochemical studies on interactions with other disturbances (e.g. fire, harvesting, etc).
