Mr. Jamil, Penolong Pegawai Kesihatan Persekitaran, gave us the replacement talk on today. We just discussed about the overview of CDC,E-notis and outbreak investigation of food poisoning.
Objective of CDC:
CONTROL OF THE SPREAD OF INFECTIOUS DISEASE
Notification of Diseases by telephone and followed by Notification of disease in the written form:
1. Dengue Fever or DHF2. Yellow Fever
(Example of the graph)- number of cases cannot be published as it is P&C)
Outbreak Definition: 2 or more cases which poses similiar symptoms after eating the same food or different type of food in a same food premise/ place.
Step of Investigation in Outbreak of Food Poisoning:
Odd ratio shows Nasi Goreng is the most probably food that cause food poisoing.
According to Mr. Jamil, Nasi Goreng and Ayam Goreng are the 2 commonest food that cause food poisoning not only in the Sik, but whole Malaysia. The affected place are usually school canteen and hostel.
Data of that particular patient such as IC number, address, date of admission, hospital name.... will be key in in the E-notis.It serves as a two-way communication tool, i.e. data flow from peripheral to center as well as from center to peripheral..If the case appears come from other district, for example, a patient from Kubang Pasu come to Hospital in Sungai Petani. Penolong Pegawai Kesihatan Persekitaran will key in the data and transfer the case to the E-notis of Kubang Pasu, not Kuala Muda. The information will be available to Kubang Pasu DHO and appropriate actions will be carried out. Conversely, if a disease is diagnosed at a DHO, the data entry is to be done by the DHO and available to the state as well as central level. However, this is rare because only confirmed cases will be entered into the system and confirmation normally done by laboratories in larger centers.
Mission: to prevent the communicable disease from occuring.
Objective of CDC:
1. Reduce disease incidence and mortality from infectious diseases that it does not become a threat topublic health.
2. Promoting a healthy lifestyle, appropriate preventive measures, detection and immediate treatment, ongoing monitoringand appropriate rehabilitation services.
3. Encourage public participation while the cooperation of various agencies / sectors to create communityhealthy and caring.

CONTROL OF THE SPREAD OF INFECTIOUS DISEASE
Section 10. Requirement to notify infectious disease.
(1) Every adult occupant of any house in which any infectious disease appears, and every personin charge of, or in the company of, and every person not being a medical practitioner attendingon, any person suffering from or who has died of an infectious disease shall, upon becomingaware of the existence of such disease, with the least practicable delay notify the officer in chargeof the nearest district health office or government health facility or police station or notify thenearest village head of the existence of such disease.

3. Diphtheria
4. Ebola
5. Food Poisoning
6. Cholera
7. Plaque

(Example of the graph)- number of cases cannot be published as it is P&C)
Green line shows the median. If the number of cases exceed more the red line ( 75percentile), something is going wrong right there. ExampleL week 15, 33, 42.. Action should be taken to investigate the cause.
OUTBREAK OF FOOD POISONING
General Definition: sudden onset of vomiting, diarrhea and other symptoms that are caused by food or drink.
Outbreak Definition: 2 or more cases which poses similiar symptoms after eating the same food or different type of food in a same food premise/ place.
Organization Cart:
Step of Investigation in Outbreak of Food Poisoning:
1. Confirm the cases: by disease notification according to district E-notis.
2. Form a team of outbreak investigation.
3. obtain the sample from the suspected spot: usually, there is nothing could be found because the food premise owner would have clean the spot before health officer team reach.
4. Implementing the steps of disease control and prevention
5. collect all the information related to the outbreak. Health officer will ask all the patients what they had eaten, type of food, duration. At the same time, another control sample with similar constant varible (2 - 5 times of the affected patients in the outbreak).E.g Outbreak of food poisoning in the school. 25 students are affected. 50-100 control sample from health students are selected.
5. collect all the information related to the outbreak. Health officer will ask all the patients what they had eaten, type of food, duration. At the same time, another control sample with similar constant varible (2 - 5 times of the affected patients in the outbreak).E.g Outbreak of food poisoning in the school. 25 students are affected. 50-100 control sample from health students are selected.
6. Develop the hypothesis
7. Plan and investigated the epidemiological data: Odd ratio, attributary risk
8. analyze the data
9. Inteprete the data and make the conclusion
10. Make the record.
• Ordinary – FWBD/KRM/BG/001 Pind 2008
• Complex - FWBD/KRM/BG/001 Pind 2008 & Scientific Write up
• Complex - FWBD/KRM/BG/001 Pind 2008 & Scientific Write up
Question to be asked during outbreak of Food Poisoning.
From the above statement, attributable risk is much more higher.
Odd ratio shows Nasi Goreng is the most probably food that cause food poisoing.
According to Mr. Jamil, Nasi Goreng and Ayam Goreng are the 2 commonest food that cause food poisoning not only in the Sik, but whole Malaysia. The affected place are usually school canteen and hostel.
Lastly, Mr. Jamil show us the E-notis. Due to private and confidential, the content is not allowed to post in here. Here is the link to E-notis: http://enotis.moh.gov.my/ . For the user account of PPKP of CDC, SIK, only information of patients from SIK is available; similarly, user account of State Health Officer will be able to access patients information from that particular state only. Once log in E-Notis, number of cases of that week and number of cases in the year will be appeared.
Data of that particular patient such as IC number, address, date of admission, hospital name.... will be key in in the E-notis.It serves as a two-way communication tool, i.e. data flow from peripheral to center as well as from center to peripheral..If the case appears come from other district, for example, a patient from Kubang Pasu come to Hospital in Sungai Petani. Penolong Pegawai Kesihatan Persekitaran will key in the data and transfer the case to the E-notis of Kubang Pasu, not Kuala Muda. The information will be available to Kubang Pasu DHO and appropriate actions will be carried out. Conversely, if a disease is diagnosed at a DHO, the data entry is to be done by the DHO and available to the state as well as central level. However, this is rare because only confirmed cases will be entered into the system and confirmation normally done by laboratories in larger centers.
By using E-notis, number of cases per year (or any duration) could be sorted out in a table.The officers in charge are expected to keep themselves updated daily by logging in everyday. E-notis enables real time information sharing and make the notification process faster and easier. It is a very useful programme to evaluate the Communicable disease in the district
