Data from these surveys are used by public health professionals to monitor trends over time—for instance, the map on seat belt use shown in chapter 1 was made using BRFSS data—but they contain only data from prevalent cases. Surveillance may be reinforced with complete blood screening in the southern region of United States and joint initiative with Mexico (Sarkar et al., 2010). Clinical signs of active disease are rarely directly apparent, and risk of TB infection is typically, although not always, associated with socioeconomically underprivileged groups often with reduced access to public health facilities (Fok, Numata, Schulzer, & FitzGerald, 2008). National Cancer Institute. Leopard skin is regarded as a classic diagnostic sign for onchocerciasis in West Africa (Edungbola et al., 1983, 1987; Edungbola and Asaolu, 1984; Carme et al., 1993) but its value in Latin America appears to be less useful due to similar changes being induced by treponemal infection (Guderian et al., 1991). For some purposes, such as epidemiological surveillance to define the endemicity of a given area, a rapid cheap method of diagnosis is sufficient. 692 0 obj <> endobj There is a need to improve pharmacovigilance and control of congenital or transplantation-related cases (WHO, 2010). For example, influenza surveillance is a coordinated international effort that aims to recognize as rapidly as possible the emergence of virus strains exhibiting new antigenic profiles or increased virulence. Pregnancy Risk Assessment Monitoring System—reproductive health. Addressing these challenges may require additional adaptations to HIV and AIDS case surveillance systems and the integration of other data sources such as STD surveillance, HIV seroincidence and behavioral surveillance, and epidemiologic research. The decreased utility of AIDS case reports for estimating trends in HIV infections has led to greater recognition of the need for national HIV surveillance. (1987) compared the prevalence of leopard skin with the prevalence of microfiladermia in areas of different endemicity and found a positive correlation. In fact, there has been concern that implementation of HIV surveillance would cause some at-risk persons to avoid HIV testing and further erode the utility of these data (30). The latter are indirectly protected because the opportunities for the transmission of the virus in the population as a whole are reduced. The guidelines encouraged the use of name-based data collection systems at the local level but allowed states to adopt the use of coded identifiers to provide additional protection against breeches of patient confidentiality or misuse of the data. In terms of influenza, scientists genotype circulating flu viruses each year so that a targeted vaccine can be prepared. It is important to note that underreporting is inherent in all passive surveillance systems, and the notifiable condition data are no different. For instance, Zika virus and its associated congenital conditions were added to the list in 2016. Rapid diagnostic tests should be promoted and should be compensated by insurance systems. The downside to active surveillance is that it is more resource-intensive, with increased personnel and financial requirements.iv. These patients are then contacted to see if they were exposed to the suspected source (here, the restaurant). Chagas disease cases have been reported in 16 European countries, with more than 4000 laboratory-confirmed cases during the 2000s (WHO, 2010). Some surveillance activities can be further characterized as population-based. Should be based on sound epidemiological and statistical principles Should be designed in … These challenges include the need to document the effects of HAART on HIV transmission rates, assess the spread of drug-resistant virus, evaluate the positive and negative effects of HAART therapy, and monitor trends in risk behavior among infected and uninfected persons (33).
