CIDT definition
Examples of CIDT in a sentence
Future studies will need to be conducted to monitor CIDT use in Salmonella surveillance and other foodborne disease surveillance as CIDTs are still a relatively novel testing type.
The objectives of this study are to identify the impact of CIDT use on Salmonella surveillance and incidence in Georgia and determine whether any change in incidence differed amongst demographic groups.
While those less than 1 year old or 1 to 5 years old were 10.41 and 9.10 times more likely of having a CIDT used to detect Salmonella in their clinical sample when compared to their odds from 2011 – 2013 (Table 6).
CIDT use could be considered one of the reasons why positive culture rate has decreased, because ever since the introduction of CIDTs positive culture rate has decreased.
There are multiple factors that will be involved in the increasing proportion of Salmonella cases reported as CIDT positive in the following years.
Initially, CIDT use for Salmonella diagnosis was highest amongst those younger than five years of age, but the margin between the age categories has shrunk.
This is shown in the data as CIDTs were introduced in 2011 and for the following years 74.88 percent of all the reported cases with a positive CIDT were amongst those younger than five years of age (n = 155).
To calculate the percent change in positive culture and positive CIDT rates for Salmonella cases over time, two Possion regression models were used (23).
After adjusting for age and gender, females > 65 years of age had no significant relationship with testing method and hospitalization status, while males diagnosed with CIDT were significantly less likely to be hospitalized than culture (aOR: 0.31 (95% CI 0.14-0.70) [Table 5].
As CIDT use increases across the country several challenges may occur for public health surveillance epidemiologists.
