Generally, laboratory testing for human immunodeficiency virus (HIV) is done for three reasons: for individual diagnosis and clinical management; to ensure the safety of blood or tissue products; and for public health surveillance. Many HIV-infected patients are unaware of their infections. The early diagnosis of infection is critical for medical and public health reasons. Its diagnosis is a two-step process that requires the sequential use of a highly sensitive screening test, followed by a highly specific confirmatory test. HIV-testing technology continues to evolve, with various tests currently available. This article reviews the current status of and recent advances in HIV testing.

PURPOSE: An injury surveillance information system (ISIS) collects, analyzes, and distributes data on injuries to promote health care delivery. The present study aimed to review the data elements and functional requirements of this system. METHOD: This study was conducted in 2019. Studies related to injury surveillance system were searched from January 2000 to September 2019 via the databases of PubMed, Web of Knowledge, ScienceDirect, and Scopus. Articles related to the epidemiology of injury, population survey, and letters to the editor were excluded, while the review and research articles related to ISISs were included in the study. Initially 324 articles were identified, and finally 22 studies were selected for review. Having reviewed the articles, the data needed were extracted and the results were synthesized narratively. RESULTS: The results showed that most of the systems reviewed in this study used the minimum data set suggested by the World Health Organization injury surveillance guidelines along with supplementary data. The main functions considered for the system were injury track, data analysis, report, data linkage, electronic monitoring and data dissemination. CONCLUSION ISISs can help to improve healthcare planning and injury prevention. Since different countries have various technical and organizational infrastructures, it is essential to identify system requirements in different settings.

OBJECTIVETo describe the occupational distribution of staff who worked on detection and reporting on public health emergency events, and to explore the effective strategies for identification and reporting on emergency events.

METHODSWe conducted a retrospective survey on 3275 emergent events reported through Public Health Emergency Events Surveillance System from 2005 to the first half of 2006. Data were collected by uniform self-administrated questionnaires by county Centers for Disease Control and Prevention, including information on events detection and reporting, etc.

RESULTSAmong event discoverers, 56.40% (1847/3275) were healthcare staff, 20.58% (674/3275) were teachers, and 15.15% (496/3275) were staff from the disease control systems. Among those event reporters, 56.82% (1861/3275) were healthcare staff, 21.77% (713/3275) from disease control system and 10.75% (352/ 3275) were teachers.

CONCLUSIONHealthcare staff and teachers played the most important role in detection and reporting on events. It would be favorable to improve the ability of events detection and reporting if we could enhance the training program to the relative staff in medical facilities and school settings especially at the grass root level.

OBJECTIVETo establish and estimate incidence of contagious bovine pleuropneumonia (CBPP), using abattoir survey as a diagnostic tool in slaughtered cattle in Northern Tanzania.

METHODSA total of 4 460 cattle were slaughtered in five abattoirs in 3 northern zone regions (Arusha, Kilimanjaro and Tanga) during the period of January to May 2004. They were examined ante-mortem for 'pneumonia signs', and 'characteristic contagious bovine pleuropneumonia (CBPP) lung lesions'.

RESULTSForty-one (0.91%) of the slaughtered cattle, the majority of which were Tanzania short horn zebu, had gross lung lesions suggestive of CBPP. The prevalence of lesions was significantly (P<0.05) higher in Karatu abattoir compared to others. No animal was detected to have lesion in Bomang' ombe abattoir. The most observed pneumonic signs included labored breathing (90%), dry cough (57%) and mucopurulent nasal discharge (47%). The gross characteristic CBPP pathological lesion, frequently encountered was left lung lesion (47%), pinkish lung (71%) and pleural adhesion (98%). Epidemiological reports show that the CBPP reported outbreaks increased from 19 in 2002, 65 in 2003 and 18 in 2004 (January-March). The corresponding number of reported deaths increased from 137 in 2002, 269 in 2003 and 77 in 2004 (January-March).

CONCLUSIONSIt's concluded from this study that CBPP is a problem in spite of the extensive awareness and vaccination campaigns. Nevertheless, a continued surveillance programme including routine checks of all cattle carcasses at the abattoir and subsequent epidemiological investigation of suspected cases are recommended.

OBJECTIVES: To describe the emergence of Neisseria meningitidis (Nm) W135 in Côte d'Ivoire and its characteristics compared to NmA.METHODS: Data on Nm samples isolated at the National Reference Center for meningitis in Côte d'Ivoire between 2007 and 2012 were analyzed. Socio-demographic data and biological information on the samples were extracted from the database. Categorical variables, such as sex and the serotype of the bacteria, were compared using the Fisher exact test, while the distribution of continuous variables, such as age, was compared using the Wilcoxon test.RESULTS: Among the 175 Nm samples, 57 were NmA, 4 were NmB, 13 were NmC, and 99 were NmW135. The geographical distribution of NmA and NmW135 did not show a significant difference according to age or sex. NmW135 was more common than NmA in the northern health districts of Cote d'Ivoire (85.9 vs. 45.5%; p < 0.001). No sample of NmA has been isolated since 2009, while 95% of the type W135 samples were isolated between 2010 and 2012.CONCLUSION: This study highlighted the emergence of NmW135 in Côte d'Ivoire, as well as the simultaneous disappearance of NmA. It is important to improve laboratory-based surveillance of meningitis to assess trends in the circulation of bacteria and to detect the emergence of new serogroups earlier.

The official investigation of death and the certification of the cause of death are among the most critical roles played by the government in maintaining public safety, carrying out public health surveillance, and compiling national health statistics. Currently, Korea has no single comprehensive act governing the postmortem examination system. Therefore, there might be some discord, contradiction, or defect in the current legal regime governing the examination of dead bodies. The authors reviewed various legislative instruments that contain the words, “death,” “corpse,” “autopsy,” “death investigation,” and “cause of death” by searching the website of the National Law Information Center (http://www.law.go.kr), which is run by the government. The authors found 64 laws and rules, of which 47 were reviewed for this study, after ensuring relevance to the subject. After a review and comparison of the acts and rules, the authors point out the discords, contradictions, and defects in the current legal regime on corpses and death investigations. They then present the need for a single comprehensive legislation addressing postmortem examination.
