Is the system to be operated by national authorities, the local or provincial authorities, the academic sector, or some combination of them? Will it be based on legally mandated reporting, will it be voluntary, or will it be a hybrid? Which organizations will be the reporting entities? How will issues of patient confidentiality be addressed?
We would suggest that the surveillance system will be discussed, established, and operated by all stakeholders, i.e., a combination of national authorities, the local authorities, academic sector, and nongovernmental organizations (and perhaps the industries). We would also suggest that disease surveillance systems rely on mandatory reporting of cases by physicians and laboratories. Most diseases will be reported to the local health department from where they are reported to the national surveillance institute.
We believe that the protection of patient privacy (recognition of a person’s right not to share information about himself or herself ), data confidentiality (assurance of authorized data sharing), and system security (assurance of authorized system access) are essential to maintaining the credibility of the surveillance system in Iran. This protection must ensure that data in a surveillance system regarding a person’s health status are shared only with authorized persons. Physical, administrative, operational, and
computer safeguards for securing the system and protecting its data must allow authorized access while denying access by unauthorized users.

Which diseases will be monitored?
The epidemiological pattern in Iran is undergoing a transition from infectious diseases to chronic diseases. Iran faces an increasing burden of chronic diseases mainly due to changing lifestyle behaviors. Thus, chronic diseases are now the greatest health problems in Iran. Indeed, there is a sense of urgency in the need to enhance the capacity for surveillance of chronic diseases (or non-communicable diseases) in Iran. However we think that a surveillance system can and should monitor communicable and non-communicable diseases, pollution, and road traffic accidents. Road accident is emerging as one of the major killers.
-
To what extent will surveillance for food-borne/enteric diseases be integrated with other, pre-existing surveillance programs in Iran (e.g., those for cholera, TB, malaria, HIV/AIDS)? Is it a matter of "adding a few more diseases to the list" or creating a new, more vertically integrated system?
We are more interested in an integrated system in order to avoid the duplication of effort and lack of standardization that can arise from independent systems.
-
What laboratory resources will be available, how will isolates be collected and transported, what techniques will be employed to characterize them (e.g., salmonella serotyping, molecular subtyping, antibiotic susceptibility, sequencing), and how quickly will these laboratory data be available to epidemiologists?
Facilities for microbial culture, characterization, and genotyping by direct automated sequencing or pyro-sequencing, or antibiotic susceptibility testing (by either traditional disc-based methods or newer genotype-based methods and molecular sub-typing) are available.
If the techniques could be used efficiently, results could be available to epidemiologists within a few hours to days.
-
Will the system be sufficiently flexible to eventually encompass a broader set of diseases, such as hepatitis A and B?
Since a flexible public health surveillance system can adapt to changing information needs or operating conditions with little additional time, personnel, or allocated funds and it can also accommodate, for example, new health-related events (or changes in case definitions or technology), we prefer to have a system flexible to accommodate other health-related events, such as cancer or hepatitis.
-
Will the collection of data be sufficiently timely to permit effective public health action?
Yes, speed between steps in a public health surveillance system is very important for us for control of health-related events, including immediate control efforts, prevention of continued exposure, and program planning.
-
How will outbreaks be recognized?
Among all surveillance approaches to early detection, whether through traditional disease reporting, specialized analytic routines for aberration detection, or surveillance using early indicators of disease outbreaks (such as syndromic surveillance), we prefer the last one (due to its ability for detecting outbreaks of diseases earlier and more completely than might otherwise be possible with traditional public health methods).
-
How will recognized outbreaks be investigated?
There are essential steps in any epidemiological investigation regardless of how the outbreak is detected. With the use of syndromic surveillance, some steps might receive greater emphasis than others. Here are the six basic steps recommended in the United States:
-
confirm existence of outbreak,
-
verify the diagnosis,
-
estimate the number of cases,
-
orient the data to person, place, and time,
-
develop and evaluate hypotheses, and
-
institute control measures and communicate findings.
