National AIDS Control Programme:AIDS Surveillance,Report No.4

This report covers the status of the HIV/AIDS epidemic in Tanzania main land by December 1990, and contains updated figures since the third report of August 1990. Moreover, data were analyzed more in depth, to reveal any trends. Maps on AIDS cases and HIV prevalence have been added as well. Figures from various sources all indicate that the HIV/AIDS epidemic continues to increase at alarming rates throughout Tanzania. Two groups are of particular importance : Antenatal clinic attenders and adolescents: Among pregnant women, attending Antenatal clinics in Mbeya, Mwanza and Bukoba region, the percentage HIV-positive women has increased from 10% to 16% (Mbeya) and from 8% to 14% (Mwanza) in little over a year. In Bukoba the percentage of infected women rose from 20.8 to 23.3. The effect on the infant mortality rate will be considerable : as 30% of children born to these women will die from AIDS within the first few years of their life, up to 5% of newborns (50 per 1,000) in Mwanza and Mbeya towns are expected to die from AIDS. Children escaping infection with HIV(up to 11%) are unlikely to have a mother (or any parent) still alive by the end of the century. Although a similar situation might not prevail throughout the country, data from bloodtransfusion services throughout the country suggest that the problem is virtually nationwide. As previously reported, a second group of great concern are adolesccents (15-19 year old) : data from blood donors show an alarming increase among the 15-19 and 20-24 year agegroups. Among 15-19 year old, the percentage seropositives was 0.0% in 1987,increased rapidly thereafter, and has reached fivefold from 1.6% to 8.2% between 1987 and 1990. Further analysis revealed that the situation among adolescents was more serious for girls than boys. In the light of these facts, there remains an urgent need to review programme strategies, in order to come up with interventions which will bring trends to a halt. Projections of AIDS Cases reported during the 1990’s are presented as well. Even if transmission of HIV would cease as from now, from the estimated number of approx. 800,000 HIV infected persons 450,000 will develop AIDS during the remainder of this decade. If transmission continues up to 1995 at a rate of 1% new HIV infections per year, 750,000 will have developed AIDS by the year 2,000

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

Three years of HIV/AIDS care and treatment services in Tanzania: achievements and challenges

The Tanzania HIV Care and Treatment Plan was launched in October 2004 aiming at providing 440,000 AIDS patients with antiretroviral drugs (ARVs) and track disease progression in 1.2 million HIV+ persons by the end of the 2008. This paper is intended to provide information to stake holders of the achievements and challenges of the HIV Care and Treatment Plan since its inception in 2004. Facility patient reports are aggregated at district and then regional level before being sent to the national level where they are aggregated to form a national report. By December 2007, 210 health facilities were offering HIV care and treatment services in Tanzania. About 123,147 (5 %) of the 2,636,785 estimated people living with HIV and AIDS were enrolled, and 71,439 (13.6 %) of the estimated 527,357 AIDS cases commenced ART. More females than males started ART, F: M ratio being 3: 2. Most (49 %) patients were started ART due to low CD4 counts (<200). About 6,618 patients had their initial ARV regimen changed due to starting anti-TB treatment 679 (10 %), peripheral neuropathy 812 (12%), skin rash 378 (6 %), and stock out 247 (4 %) or other reasons (18 %), while 2,653 (42 %) had no reason recorded. The proportion of patients still alive and on ART at 6, 12 and 24 months after initiation of treatment was 60 %, 60 % and 50 %, respectively, while those collecting ARVs on schedule was 34 %, 25 % and 10 % respectively. About 3,084 patients developed TB after starting ART, of whom 1,557 (~50%) patients during the first three months of treatment. During the three years (2004-2007) of HIV care and treatment services in Tanzania, there has been an increase in the number of CTC facilities, geographical coverage of services, the number of enrolled patients and those on ART. However, the set target for ART services has not been achieved and there are significant geographical variations in these achievements, which do not correspond with either population density or disease burden. Efforts should be made to i) ensure equitable accessibility when scaling up ART services in Tanzania, ii) improve the recording and reporting system, and iii) harmonize the activities of various stakeholders
