Public Health Surveillance-Free-Samples for Students-Myassignment

Question: Discuss about the Surveillance is a valuable epidemiological tool serving many purposes, it is an ongoing systematic collection of health data. When surveillance data is collected, analyzed, interpreted and reported appropriately, It can provided important information about disease patterns to inform public health practice and policies. Answer: It can be agreed that surveillance is an important epidemiological tool as it helps to estimate the health status of the population. It is the measure of the need for intervention and is well explained in the post. The given post very precisely highlights the significance of the surveillance systems. It gives insights into the classification of the surveillance system that is the active and the passive system. The post explains why more attention is given to the passive surveillance system than the active one. This post is well supported with the relevant references. It would have been better if it as also supported with some examples. There are many examples that can justify the post. For instance The Transfusion Transmitted Injuries Surveillance System (TTISS) established by Canada's public health agency was effective in tracking the transfusion services in the Canadian hospitals. With the help of this tool, a total of 3,957 adverse reactions were reported between 2006-2012. The majority of the reactions due to transfusions led to minor injuries or no sequelae.To monitor the adverse transfusion reactions, there is a need for further strengthening the TTIS (Mounchili et al. 2014). Passive surveillance is mostly preferred because there are challenges with active surveillances system. Environmental public health surveillances are complicated due to some challenges. Poor understanding of the disease hampers the ability to link the particular environmental causes to the adverse outcomes. The challenge is also due to multiple potential causes of disease and inadequate measure of exposure. Public policies are influenced disproportionately to scientific information. It is because the public alarm to the hazard of concern is out of proportion. Further, during the environmental exposure surveillance, the biological markers may become the critical elements (Gilbert and Cliffe 2016). References Gilbert, R. and Cliffe, S.J., 2016.
