Mumps is an intense viral contamination described by fever, swelling and delicacy of at least one salivary organs, ordinarily the parotid organs (before the ears). Intricacies of mumps disease can incorporate hearing misfortune, pancreatitis, orchitis (irritation of the balls), meningitis/encephalitis and unconstrained premature birth. 20-30% of all cases are asymptomatic; these cases can be transferable.

Slide 3

Transmission Mumps is spread by direct contact with respiratory beads, or salivation from a contaminated individual. The hatching time frame is typically 16 to 18 days however can go from 14 to 25 days. A contaminated individual is transferable for up to 7 days before the onset of parotitis and up to 9 days after.

Slide 4

Surveillance Mumps is a reportable illness in Ontario. Under the Health Protection and Promotion Act , doctors and other indicated medicinal services professionals are required to report all associate and affirmed cases with mumps to their nearby restorative officer of wellbeing. Wellbeing unit staff enter mumps case data in the coordinated Public Health Information System (iPHIS) and contact the Public Health Division of the MOHLTC in the event that they require help with case and episode administration.

Slide 5

The Mumps Outbreak in the Maritimes There has been a progressing episode in three Maritime areas - Nova Scotia, New Brunswick and Prince Edward Island since the center of January 2007 Cases have been sent out to nine out of 13 Canadian Provinces and Territories As of October fifth , 2007, 836 affirmed cases identified with the flare-up have been accounted for from all the influenced Provinces 25 affirmed cases in Ontario Most detailed cases have happened in college understudies (middle age 22).

Slide 6

The Mumps Outbreak in the Maritimes Case definitions: For the reasons for follow-up of cases in Ontario connected to the Maritimes episode, an affirmed flare-up case is characterized as a case with a past filled with late travel or living arrangement in the Maritimes since January 2007 and research center affirmation of mumps or clinical ailment in a man who is epidemiologically connected to a lab affirmed case Please take note of that this definition contrasts from an affirmed reconnaissance case definition utilized for the motivations behind routine commonplace mumps observation

Slide 7

iPHIS Enhanced Surveillance Directive (ESD) and Mumps Surveillance in Ontario Several instances of mumps related with the bigger flare-up in the Maritimes were accounted for in Ontario beginning in the spring of 2007. To encourage the expanded reconnaissance prerequisites for this circumstance, the Ministry of Health and Long Term Care (MoHLTC) issued one of its initially Enhanced Surveillance Directives (ESD) to Public Health Units (PHUs) in the week after week iPHIS Notice. The reason for an ESD is to give guidance to PHUs on information passage needs in light of pressing irresistible illness circumstances, alongside particular guidelines on the best way to enter required data into iPHIS.

Slide 8

iPHIS ESD according to the information section guidelines in this mandate, please enter every one of the fields recorded in the customer statistic and case points of interest screens (Table 1) for any new mumps cases (affirmed, PUI), into iPHIS inside one business day of accepting this data . Notwithstanding all compulsory fields in the customer socioeconomics, please enter the accompanying: Origin Country of Birth Please enter the accompanying data when it is accessible. These cases must be connected to common episode number 0000-2007-004. Lab Results (Tables 2-4) Symptoms (Table 5) Exposures (Tables 6-8)- Exposure data is particularly essential keeping in mind the end goal to distinguish cases connected to Nova Scotia and mumps cases because of importation spread (i.e. auxiliary cases) Hospitalization data (Table 9) Immunizations (Table 10)- including dosage number Complications (Table 11) Outcome (Table 12)

Slide 9

Using the Data for Surveillance The MoHLTC produced every day covers the information asked for in the ESD to screen mumps cases related with the Maritimes episode crosswise over Ontario. Notwithstanding, a few difficulties were experienced when directing improved mumps reconnaissance at the commonplace level utilizing iPHIS, the most genuine of which was acquiring convenient and finish information.

Slide 10

Epidemiology of Mumps cases in Ontario Associated with the Maritimes Outbreak

Slide 12

Confirmed Case Characteristics Male: Female proportion = 4:1 Median age = 23 years (range:19-66 years) Symptoms: 92% (N=23) of cases had either one-sided or respective parotitis 64% (N=16) had fever 35% (N=7) of guys had orchitis Immunization: For 15 of the 25 cases vaccination data was recorded 93% (N=14) of these cases had just a single dosage of MMR 6% (N=1) of these case had two measurements of MMR Complications: 1 over night doctor's facility stay, 1 instance of hearing misfortune

Slide 13

Improving Surveillance Response Data Quality Completeness of records Validity of information recorded Timeliness of announcing Timeliness mirrors the speed between ventures in a general wellbeing observation framework Critical measure is the time amongst onset and answering to the PHU's and afterward to the MOHLTC Has to be perceived that a few issues are out of the PHUs control Once the data is gotten from the doctor or lab it has be gone into iPHIS as quickly as time permits.

Slide 14

Data Quality Exposure data on Mumps cases Was not generally total Was entered days after the case subtle elements were gone into iPHIS Some instances of Mumps related with the Maritimes episode were entered as sporadic cases Incomplete records in iPHIS Immunization data inaccessible on 40% of all cases Not known whether cases were understudies, this was essential given the companion required in this flare-up

Slide 15

Timeliness of Reporting Delayed section of cases into iPHIS notwithstanding the ESD which called for passage of specific information components with in 24 hours Approximately 44% of cases were accounted for 3 days or more after the wellbeing unit had been told Delayed passage of all information components into iPHIS once a case had been entered Much of the case data was gotten in an impromptu way by verbal contact with the PHU or the program zone rather than through iPHIS information passage

Slide 16

Conclusion Due to the impediments distinguished, this flare-up couldn't be overseen utilizing just iPHIS If this flare-up had been bigger we would not have possessed the capacity to lead viable reconnaissance and impart the suitable data to PHAC/accomplices in an auspicious way. In the event that we can depend on iPHIS information, reconnaissance can be led in a more productive way Typically led follow up to get some information about the points of interest of the case later on every single required dat components ought to be entered as asked for in the ESD with in the asked for time period
