Under-reporting in hepatitis B notifications

Notification and laboratory data for the period January 1985 December 1988 were compared in order to estimate: (i) the minimum level of under-reporting of hepatitis B; and (ii) the consistency of the level of under-reporting, both regiorially and nationally. Ratios between hepatitis B notifications and positive hepatitis B laboratory tests (reporting ratios) were calculated to quantify the discrepancy between these parameters. There were at least 7 positive hepatitis B laboratory results for each notified case of hepatitis B during each year studied. The differences between the national reporting ratios for each of the study years were small, indicating that nationally the level of reporting of hepatitis B is fairly consistent. The Cape region had the highest and most constant level of hepatitis B reporting compared with other regions. We conclude that the national incidence of hepatitis B is at least 7 times higher than that calculated from notification data. Further, the inter-year analysis of hepatitis B notification data to identify trends nationally and within the Cape region is valid. However, caution is called for when comparing the incidence rates between regions due to inter-region and region-specific inter-year inconsistencies in reporting levels

Unsustainability of a measles immunisation campaign - rise in measles incidence within 2 years of the campaign

The 1990 national mass measles immunisation campaign resulted in a marked reduction in measles incidence in Natal/KwaZulu in the first 6 months after the campaign. Data from the measles ward admissions book at Clairwood Hospital were collated for the period 1 January 1989 to 31 May 1992 to assess the sustainability of the effects of the campaign. For the first 12 months after the campaign, measles admissions were consistently low. Thereafter, the number increased steadily, rising sharply to above precampaign levels 21 months after the campaign. The age distribution of measles patients indicated that the initial fall in the 10 - 12-month age group had been reversed in the second year after the campaign, suggesting that the high vaccination coverage achieved for this age group during the campaign had not been maintained. Measles admissions to Clairwood Hospital indicate that the effect of the measles imInunisation campaign has not been sustained and that urgent action is required to avert a possible epidemic.S Afr Med J 1993; 83: 322-323

A comparative experimental design and performance analysis of Snort-based Intrusion Detection System in practical computer networks

As one of the most reliable technologies, network intrusion detection system (NIDS) allows the monitoring of incoming and outgoing traffic to identify unauthorised usage and mishandling of attackers in computer network systems. To this extent, this paper investigates the experimental performance of Snort-based NIDS (S-NIDS) in a practical network with the latest technology in various network scenarios including high data speed and/or heavy traffic and/or large packet size. An effective testbed is designed based on Snort using different muti-core processors, e.g., i5 and i7, with different operating systems, e.g., Windows 7, Windows Server and Linux. Furthermore, considering an enterprise network consisting of multiple virtual local area networks (VLANs), a centralised parallel S-NIDS (CPS-NIDS) is proposed with the support of a centralised database server to deal with high data speed and heavy traffic. Experimental evaluation is carried out for each network configuration to evaluate the performance of the S-NIDS in different network scenarios as well as validating the effectiveness of the proposed CPS-NIDS. In particular, by analysing packet analysis efficiency, an improved performance of up to 10% is shown to be achieved with Linux over other operating systems, while up to 8% of improved performance can be achieved with i7 over i5 processors

Understanding and responding to HIV risk in young South African women: Clinical perspectives

Young women (15 - 24 years) contribute a disproportionate 24% to all new HIV infections in South Africa – more than four times that of their male peers. HIV risk in young women is driven by amplifying cycles of social, behavioural and biological vulnerability. Those most likely to acquire infection are typically from socioeconomically deprived households in high HIV-prevalence communities, have limited or no schooling, engage in transactional sex or other high-risk coping behaviours, and have a history of sexually transmitted infections (STIs) and/or pregnancy. Despite the imperative to prevent HIV acquisition in young women, there is a dearth of evidence-based interventions to do so. However, there are several steps that healthcare workers can take to improve outcomes for this key population at the individual level. These include being able to identify high HIV-risk young women, ensuring that they receive the maximum social support they are eligible for, providing reliable and non-judgemental counselling on sexual and reproductive health and relationships, delivering contraceptives and screening and treating STIs in the context of accessible, youth-friendly services

Stigma impedes AIDS prevention

Thirty years since the first cases of AIDS were described, there is much to celebrate regarding progress in the treatment and prevention of the disease. Within the past year alone, several studies have revealed that antiretroviral drugs can prevent the sexual transmission of HIV. Yet worldwide, many people who are potentially exposed to the virus avoid finding out whether they carry it, or deny that they are at risk of contracting it. Unless people establish whether they are infected, they will not be able to be adopt the most appropriate preventive measures. As scientists and clinicians, our ability to overcome this denialism will determine whether we ultimately succeed in using combinations of all the preventive and therapeutic tools now available to slow, and eventually stop, the HIV/AIDS pandemic

SURVEY: AUDIO READING SYSTEM FOR BLIND PERSONS

Audio Reading System is used to help blind people to read the text based on camera as input device and speaker as output device. The system used the OCR algorithm to extract the text from input image and Text-to-Speech algorithm to convert text into corresponding voice. In this paper, we review newest research of audio reading system. We discuss the hardware and software, which is used, on system for different types approach. Finally, the result of this paper that is: Raspberry pi, python and tesseract are best tools used in Audio reading system. Also the braille and finger print devices are not efficient and not easy to use

High AIDS-related mortality among young women in rural KwaZulu-Natal

Objective. To establish mortality rates and cause of death in a rural community in KwaZulu-Natal. This study was conducted as part of a demographic and health survey to assess the impact of HIV infection in this community. Methods. A cross-sectional survey was conducted between February and July 2004. The survey made use of structured questionnaires and verbal autopsies, which yielded detailed information at household level, including the demographic profile of residents, mortality rates and cause of mortality between February 2003 and February 2004.Results. The overall mortality rate in this community was 2.9 deaths per 100 person-years (95% confidence interval (CI): 2.5 - 3.3 per 100 person-years). The highest mortality rate among women occurred in the 30 - 34-year age group, while among men it occurred in the 35 - 39 and > 60-year age groups. Of the 185 verbal autopsies reported, 77 deaths (42%) were attributable to AIDS. The survey revealed that women aged 20 - 24 and men aged 35 - 39 years were bearing a disproportionately large burden of AIDS-related mortality in this community.Conclusion. AIDS-related mortality was found to be disproportionately high in young women in this small rural community, and the majority of deaths resulted from pulmonary tuberculosis. The need to strengthen prevention and treatment efforts in this and similar settings is highlighted
