Prevalence and risk factors for HIV among people aged 50 years and older in Rombo district, Northern Tanzania

Background: It is estimated that over ten percent of the 36.7 million people living with HIV (PLWHIV) globally, are those aged ≥50 years. The objective of this study was to determine the prevalence and risk factors for HIV among adult aged 50 years and above in Rombo district, northern Tanzania.Methods: This cross sectional study was conducted from April to June 2015 among older adults aged ≥50 year in Rombo district. Interviews were conducted to collect information on socio-demographic characteristics, reproductive and sexual health characteristics of the participants, knowledge on HIV transmission, prevention and risk perception and on awareness and knowledge on voluntary and counselling testing services. In addition, a blood sample was taken for HIV diagnosis.Results: A total of 600 people were enrolled. Their age ranged from 50 to 90 years with mean of 64.9 (±SD 10.3) years. The HIV prevalence was 1.7% (n=10) and it was higher among women (2.1%) than men (1.3%). Sixty-percent (n=350) were knowledgeable on HIV transmission and only 40% (n=216) on HIV prevention. In bivariate analysis, age of partner <50 years, ever use of condoms, poor knowledge on HIV prevention and perception of risk on HIV were significantly associated with HIV. However, only partner’s age of <50 years remained significant after controlling for confounders.Conclusion: HIV prevalence and overall knowledge on its transmission among older adults in this rural population were low. There is a need for strategies to improve HIV preventive knowledge and testing in this group in order to continue keeping the transmission at low levels

HIV/AIDS/STI Surveillance Report:Report Number 21

Since the first cases of Acquired Immunodeficiency Syndrome (AIDS) in Tanzania were reported in 1983, the epidemic has evolved from being a rare and new disease to a common household problem, which has affected most Tanzania families. The mainland Tanzania faces a generalized human immunodeficiency virus (HIV) and AIDS epidemic, with an estimated 6.5% of the mainland population infected with HIV (7.7% of adult women and 6.3% of adult men). Overall, 1.4 million Tanzanians (1,300,000 adults and 110,000 children) are living with HIV infection, in a total population of 41 million. The social, economic, and environmental impact of the pandemic is sorely felt as an estimated 140,000 Tanzanians have perished, leaving behind as estimated 2.5 million orphans and vulnerable children, representing approximately 10-12% of all Tanzanian children. As elsewhere in sub-Saharan African, the underlying factors of poverty, migration, marginalization, lack of information and skills, disempowerment, and poor access to services raise the risk of HIV and have an impact on the course and spread of the pandemic. Close to 85% of HIV transmission in Tanzania occurs through heterosexual contact, less than 6% through mother-to-child transmission, and less than 1% through blood transfusion. There continues to be a significant difference in the prevalence among urban (10.9%) and rural (5.3%) areas of the country. The National AIDS Control Programme (NACP) of Tanzania was founded in 1987 to champion the health sector response to the HIV epidemic. The primary objectives of the program were to reduce spread of HIV infection, screen blood supplies, enhance clinical services for HIV/AIDS patients and improve STI treatment, prevention of mother-to-child transmission (PMTCT), advocate behavioral change and conduct epidemiologic surveillance and other research. The program phases started with a two-year phase called Short Term Plan\ud (1985-1986). Subsequent phases were termed Medium Term Plans lasting for five-year periods. Through these program phases successful national responses have been identified, the most effective ones being those touching on the major determinants of the epidemic and addressing priority areas that make people vulnerable to HIV infection. These include the following; Since early eighties great efforts have been made to reduce spread of HIV infection through screening of donor blood, advocating behavioral change, condom promotion and improvement of STI treatment. In addition a number of epidemiologic surveillance have been conducted to monitor the trend of HIV infection among different subpopulations e.g. blood donors and pregnant women attending antenatal clinics. In 2004, the National Blood Transfusions Services (NBTS), which is a centralized system of coordinated blood transfusion services, was established. The NBTS is responsible for collection, processing, storage and distribution of safe blood and blood products to health facilities. At the moment NBTS coordinates eight zonal blood transfusion centers, namely Lake Zone-(LZBTC) in Mwanza region, Western-(WZBTC) in Tabora, Northern (NZBTC) in Kilimanjaro region, Eastern (EZBTC) in Dar es Salaam, Southern highlands (SHZBTC) in Mbeya, Southern (SZBTC) in Mtwara and Zanzibar and a military zone –Tanzania People’s Defence Force (TPDF). Since the establishment of NBTS, donated blood in the eight zones is systematically screened for HIV, hepatitis B virus (HBV), hepatitis C virus (HCV) and syphilis. The National HIV Care and Treatment Plan (NCTP) was launched in October 2004, with the main focus of a rapid scaling up of HIV care and treatment services, aimed at having more than 400,000 patients on care and treatment by the end of 2008 and, at the same time, follow up disease progression in 1.2 million HIV+ persons who are not eligible for ntiretroviral therapy (ART). Prevention of Mother to Child Transmission of HIV (PMTCT) services were established in 2002 , providing a package of services that include: counseling and testing for pregnant women; short-course preventive ARV regimens to prevent mother-to-child transmission; counseling and support for safe\ud infant feeding practices; family planning counseling or referral; and referral for long-term ART for the\ud child. This report which covers the NACP activities through December 2008 has been arranged in five chapters and is intended for various stakeholders, primarily those working within the health sector.\u

Decentralization of viral load testing to improve HIV care and treatment cascade in rural Tanzania: observational study from the Kilombero and Ulanga Antiretroviral Cohort

INTRODUCTION: Monitoring HIV viral load (HVL) in people living with HIV (PLHIV) on antiretroviral therapy (ART) is recommended by the World Health Organization. Implementation of HVL testing programs have been affected by logistic and organizational challenges. Here we describe the HVL monitoring cascade in a rural setting in Tanzania and compare turnaround times (TAT) between an on-site and a referral laboratory. METHODS: In a nested study of the prospective Kilombero and Ulanga Antiretroviral Cohort (KIULARCO) we included PLHIV aged >/= 15 years, on ART for >/= 6 months after implementation of routine HVL monitoring in 2017. We assessed proportions of PLHIV with a blood sample taken for HVL, whose results came back, and who were virally suppressed (HVL /= 1000 copies/mL). We described the proportion of PLHIV with unsuppressed HVL and adequate measures taken as per national guidelines and outcomes among those with low-level viremia (LLV; 100-999 copies/mL). We compare TAT between on-site and referral laboratories by Wilcoxon rank sum tests. RESULTS: From 2017 to 2020, among 4,454 PLHIV, 4,238 (95%) had a blood sample taken and 4,177 (99%) of those had a result. Of those, 3,683 (88%) were virally suppressed. In the 494 (12%) unsuppressed PLHIV, 425 (86%) had a follow-up HVL (102 (24%) within 4 months and 158 (37%) had virologic failure. Of these, 103 (65%) were already on second-line ART and 32/55 (58%) switched from first- to second-line ART after a median of 7.7 months (IQR 4.7-12.7). In the 371 (9%) PLHIV with LLV, 327 (88%) had a follow-up HVL. Of these, 267 (82%) resuppressed to < 100 copies/ml, 41 (13%) had persistent LLV and 19 (6%) had unsuppressed HVL. The median TAT for return of HVL results was 21 days (IQR 13-39) at the on-site versus 59 days (IQR 27-99) at the referral laboratory (p < 0.001) with PLHIV receiving the HVL results after a median of 91 days (IQR 36-94; similar for both laboratories). CONCLUSION: Robust HVL monitoring is achievable in remote resource-limited settings. More focus is needed on care models for PLHIV with high viral loads to timely address results from routine HVL monitoring

Rereading Texts of “Targeted Killings” in the Hebrew Bible: An Indigenous Knowledge Systems Perspective

The biblical text is replete with narratives of targeted killings (TKs), although it is not stated as such. For example, David is depicted as “a man after God’s own heart” (1 Sm 13:14). However, when David was on his deathbed, he summoned his son Solomon to kill his enemies, namely Joab son of Zeruiah (1 Ki 2:5) and Shimei son of Gera (1 Ki 2:8). From an indigenous knowledge systems (IKS) perspective, this essay analyses David’s killings in view of TKs in the following eras: the apartheid era in South Africa; the post-apartheid period in South Africa; colonial Rhodesia; during the liberation struggle for Zimbabwe’s independence; and in the post-independence Zimbabwean era. It is explored that for the majority of African cultures, the spirit of a killed person will always return as ngozi (“avenging spirit”) to afflict the killer or a blood relative of the guilty person with various curses, illnesses or deaths

Prevalence and factors influencing modern contraceptive use among HIV-positive women in Kilimanjaro region, northern Tanzania

Abstract Background Mother-to-Child-Transmission (MTCT) of HIV is still a public health problem in sub-Saharan Africa. The region has a high unmet need for family planning and high unplanned pregnancy rates among HIV-positive women. Most efforts to prevent MTCT of HIV have focused on the third prong, a strategy which offers antiretroviral (ARV) drugs to HIV-infected pregnant women and their exposed infants. However, the effective use of contraceptives to prevent unplanned pregnancies among women living with HIV is more effective in reducing HIV MTCT. This study aimed at determining the prevalence and factors influencing modern contraceptive use among HIV-positive women in northern Tanzania. Methods This was a cross-sectional study conducted between January and June 2014 in three selected districts of Kilimanjaro region, Tanzania. Data were collected during face-to-face interviews with HIV-positive women attending Care and Treatment Clinics (CTC) in the selected districts. Multivariate logistic regression analysis was used to determine independent predictors of modern contraceptive use. Results In total 672 HIV-positive women were enrolled. Their mean age was 36.4 years (±7.7). Fifty four percent (362) were currently using modern contraceptives, and the most common method used was male condoms 76% (275) followed by Depo-Provera 28% (101). A total of 33% (121) of the users reported dual contraceptive use. Women with primary education [Adjusted Odds Ratio (AOR) = 7.54, 95% Confidence Interval (CI): 1.51–17.48, P = 0.014]; post-secondary [AOR = 6.23, 95% CI: 1.14–14.07, P = 0.035]; not currently on ARVs [AOR = 11.29, 95% CI: 2.60–19.94, P = 0.001]; currently sexually active [AOR = 8.40, 95% CI: 4.47–15.78, P < 0.001]; ever discussed contraceptive use with partner [AOR = 3.68, 95% CI: 1.67–8.11, P = 0.001]; and being counseled on dual contraceptive use at CTC [AOR = 2.94, 95% CI: 1.66–5.23, P < 0.001]; had significantly higher odds of currently using modern contraceptive methods. Conclusions Given the population studied, the prevalence of modern contraceptive use was low. Strategies are required to increase the use of dual and long-term contraceptive methods among women who do not want more children in order to reduce MTCT, and to improve maternal and child health in the region. Programme managers and health care providers need to identify counseling strategies that are specific to HIV-positive women that not only impart knowledge on contraceptives, but also address the issue of responsibility for influencing HIV transmission in the community
