The phrase "a set of outbreak cases" is correct and usable in written English.
It can be used when discussing a collection or group of specific instances of outbreaks, often in a medical or epidemiological context.
Example: "The researchers analyzed a set of outbreak cases to identify common transmission patterns."
Alternatives: "a collection of outbreak instances" or "a group of outbreak occurrences."
In Brazil the average incidence rate of dengue cases during outbreaks was 538 per 100 000 population, clearly in excess of the 300-threshold (detailed analysis of a set of dengue outbreaks to be published by the Brazilian partner).
This is essentially a portfolio problem (Convertino and Valverde 2013) in which a large set of outbreak source alternatives exist and the whole set is evaluated considering average risk and variance, where in this case the "risk" is related to the inability to predict the correct outbreak patterns in space and time.
Our analysis concentrates on a single outbreak of 318 cases, rather than a set of past Ebola outbreaks, which have ranged from a small number of cases to several thousand (Fig. 6B).
We performed different analyses with a set of nine MLST typed outbreak and four non-outbreak strains.
We report a larger set of 20 cases during this outbreak in Pakistan, supporting human-to-human-to-human transmission.
We then compared the health outcomes (i.e., incidence, mortality, time to peak and time to reach a set percentile of total cases per outbreak) using the Mann-Whitney test using SAS statistical software version 9.1 (SAS Institute Inc., Cary, NC, USA).
During the German STEC outbreak, rapid genome sequencing together with crowd-sourced bioinformatics analyses led to the development of a set of diagnostic reagents that could then be used in defining cases within the outbreak [ 3].
In an epidemiological study, the intensity of disease outbreak cases varies with time.
Norovirus outbreaks were also larger than outbreaks of other diseases with a mean number of outbreak-associated cases of 30.
Had the set of cases in the C difficile surveillance reconstruction been sequenced in real time, an outbreak would have become apparent after the second case, and it is possible that subsequent transmissions might have been prevented, particularly as compliance with infection control measures was incomplete at the time of the outbreak.
