compare/contrast the three methods of surveillance

1. disease-specific surveillance: targets a specific disease or set of symptoms in a defined population. Disease-specific surveillance can be done with a wide range of pathogens and is useful for following disease trends. ex: the National TB Surveillance System in the US collects info on TB cases. If a person tests positive for Mycobacterium tuberculosis, the state health department sends an anonymous report to the NTSS. The NTSS then summarizes all data received, which is subsequently provided to the CDC for publication. ex: the Gonococcal Antimicrobial Surveillance Programme was implemented to provide data on the antibiotic susceptibility of N. gonorrhoeae strains circulating in Europe. 2. Syndrome/Symptom-based surveillance: These surveillance systems are based on real-time data collection. The real-time (or near real-time) tracking of data on the occurrence of syndromes or symptoms to identify potential public health threats. The data collected are nonspecific indicators of the health status of a population, such as school or work absenteeism rates. These reporting or tracking systems can be automatically generated and used to assist public health leaders in making decisions about the implementation of programs and policies for the prevention and control of infectious diseases. ex: the Electronic Surveillance System for Early Notification of Community-Based Epidemics (ESSENCE I, 1999) was used to perform worldwide monitoring of the health status of all army personnel in all US treatment facilities. ESSENCE II, the latest version, performs automated surveillance of military and civilian medical data. 3. Event surveillance: The gathering of data from diverse Internet sources in real time or near-real time (e.g., ProMED-mail, HealthMap, Flu Near You). Data are collected from news or online discussion platforms in various languages to detect potential or confirmed epidemics. Event surveillance systems also can be used to monitor developing countries and gather data in multiple languages in order to detect true global epidemics.

List and briefly discuss problems that compromise human health in large refugee camps.

Large refugee camps presents a multitude of problems. A major one that sticks out is the fact that there are so many people in close quarters. For example, if just one person catches any sort of communicable disease, it will likely spread very rapidly among the rest of the refugees. Also, because there are so many of them, it is likely that any health issues they come across will not be addressed immediately. For example, if someone gets sick, they probably will not get attention for a few days because of the sheer amount of other people that have other problems needing to be addressed. Another key problem that could arise would be if a refugee becomes/is pregnant. The attention that is required during prenatal care is very important and probably would not be received as often as needed with so many people, along with the fact that people in refugee camps are normally not the government's top priority.

Explain why life expectancy increased in many nations over the 20th

Life expectancy increased over the last century because of the development of sanitation. With scientists like Pasteur, Koch, and more, their discoveries in bacteriology were critical in the development of sanitation. For example, the germ theory of disease was really what kick started the growth of sanitation because we realized that diseases were linked to microbes all around us.

Describe the work of local health department as partners in the control of infectious diseases.

Local health departments have come along way. In the early 1900s, not even every state had a health department, and the ones that did exist were driven by urgent needs only. Now, local health departments have transformed into an organized approach that is much more proactive, rather than reactive. They even came up with strategies to control infectious diseases like malaria, TB, and the plague. Current health departments collect data, monitor environmental health and food safety, take preventative measures for diseases before they even become a problem, and more. Public health departments are key players in monitoring the spread of infectious disease, and also really preventing epidemics in the first place.

Approximately 892 million people still defecate in the open worldwide. (a) Discuss why this is happening. (b) What steps would you take to solve this problem?

People still defecate in public around the world mainly due to a lack of access to real toilets. This is mainly just happening in third world countries, where people cannot afford luxuries like toilets, therefore they have no other option. The first step I would take to solve this problem would be in education. I feel like the major source of the problem lies there because many of these people see defecating in the open their only option, with absolutely no knowledge of the consequences of their actions. If they knew how much of a correlation defecating in the open has with intestinal diseases, they may be more open to working harder at making an infrastructure change that could fix it.

Kampung Improvement Program

Program in Indonesia developed to improve public sanitation in order to reduce disease caused by exposure to the pathogens present in human waste -focus on covering open sanitation drains and bringing reasonably clean water to famillies

Orangi Pilot Project

Program in Pakistan developed to improve public sanitation in order to reduce disease caused by exposure to the pathogens present in human waste

Explain why disease surveillance systems are rapidly growing and evolving.

Surveillance systems are rapidly growing and evolving so that we can have an overall more proactive approach to public health. There are three key strategies that are evolving: disease-specific, syndrome/symptom-based, and event. Each strategy covers a different approach to surveillance. Disease-specific focuses on the trends of a disease, while syndrome/symptom-based looks at real-time data, and event looks at internet sources. This area of focus needs to keep growing so that all of the bases are covered when it comes to following infectious diseases and keeping our population as healthy as possible through preventative measures, rather than curing what has already happened. ESPECIALLY W NEW AND REEMERGING INFECTIONS
