Abstract
Background: Thirty years after the discovery of the human immunodeficiency virus (HIV), prevention is difficult to achieve and the pandemic does not show any sign of abating. Antiretroviral therapy (ART) is now rolled out at a large scale in lower-income countries. ART with fully suppressive antiretroviral (ARV) drugs combinations lowers HIV viral load (VL) in all body compartments and decreases the risk of transmission to a low level. It is thus legitimate to raise the following question: Could ART contribute to reducing transmission at individual and population level? Not only may earlier treatment reduce HIV incidence (acquisition of new cases of HIV infection through sexual or mother-to-child transmission), it may also benefit the individual. The long-term benefits of starting ART earlier would likely be of particular importance in settings where the incidence of life-threatening HIV-related diseases occurring at relatively high CD4 levels (tuberculosis, invasive bacterial diseases, and possibly malaria) is substantial, a typical situation in most sub-Saharan Africa including South Africa.
Research hypothesis: HIV testing of all adult members of a community, followed by immediate ART initiation of all, or nearly all, HIV-infected participants regardless of immunological or clinical staging will prevent onward transmission and reduce HIV incidence in this population.
Objectives: To estimate the effect of ART initiated immediately after HIV diagnosis, irrespective of CD4 count criteria, on the reduction in incidence of new HIV infections in the general population in the same setting.
Setting: The trial will be conducted in Hlabisa sub-district, Umkhanyakude district, Northern KwaZulu-Natal, South Africa. This rural setting of 1430 km2 in size has a population of approximately 220 000 Zulu-speaking people. In this sub-district, the Africa Centre for Health and Population studies, a research institute at the University of KwaZulu-Natal (<http://www.africacentre.com>) carries out socio-demographic and HIV surveillance and clinical research. The KwaZulu-Natal Department of Health and the Africa Centre established in 2004 the Hlabisa HIV Treatment and Care Programme, devolved to all 17 primary health care clinics in the sub-district. By mid-2013, over 28 000 HIV-infected people eligible for treatment had been initiated on ART; patients' treatment eligibility is determined by South African guidelines.
Design: A cluster-randomised trial with 22 (2×11) clusters will be conducted within the Hlabisa sub-district, covering a total population of approximately 22 000 inhabitants aged 16 years and above, of whom an estimated 17 600 will be HIV-negative. A full prevention and HIV testing strategy will be provided in both the intervention and control arms, consisting of the current range of community and clinic testing options plus the implementation of 6-monthly rounds of home-based HIV testing. The adult HIV-infected population residing in the intervention clusters will be offered immediate ART initiation upon HIV diagnosis whereas the HIV-infected population in the control clusters will be offered ART according to national guidelines (CD4 less than 350 cells/ml, WHO stage 3 or 4 disease or MDR/XDR TB). The protocol outlines the overall trial design, which has HIV incidence as primary outcome. The first phase of the trial (24 months) will take place in ten (2×5) clusters, with two to three rounds of home-based HIV testing and surveillance according to the trial protocol, and has as main outcome acceptability and feasibility rather than HIV incidence. If results from the first phase indicate acceptability and feasibility, the trial will be rolled-out to the other 12 clusters during the second phase. Possible amendments to the trial for phase 2 will be based on the advice from the Data Safety Monitoring Board and the Scientific Advisory Board.
Trial eligibility criteria: To be aged 16 years and above and a member of a household in the designated cluster (head of household defines membership status in KwaZulu culture).
Treatment eligibility criteria: Those already on ART from the Hlabisa HIV Treatment and Care Programme may opt to transfer their care to the trial; the few (if any) people already on ART from private/other HIV treatment providers will be encouraged to take part in the trial monitoring procedures, and be given the opportunity to change ART provider to the Hlabisa HIV Treatment and Care Programme trial.
Trial treatment: The standard first-line drug regimen will be the combination of tenofovir (TDF) + emtricitabine (FTC) + efavirenz (EFV) once daily, i.e. Atripla®. This will also be applicable to pregnant women irrespective of the trimester of pregnancy.

Coverage
Geographic Coverage
Ten survey clusters located in Hlabisa sub-district, Umkhanyakude district, of northern KwaZulu-Natal, South Africa.
The Hlabisa health sub-district is a rural setting of 1 430 km2 in size, with a population of approximately 220 000 Zulu-speaking people of whom 3.3% are located in a formal urban township (KwaMsane), 19.9% in peri-urban areas and the remainder (76.8%) classified as living in a rural area. The rural population lives in scattered homesteads that are not concentrated into villages or compounds (as would be the case in many other parts of Africa).

The rural population lives in scattered homesteads that are not concentrated into villages or compounds (as would be the case in many other parts of Africa).
Universe
Clusters: the trial area consists of 150 local areas (neighbourhoods). These were aggregated into 34 clusters of between one and six contiguous neighbourhoods, each cluster comprising an average of 1 000 individuals >15 years of age. Clusters were designed to encompass social networks based on earlier studies. TasP phase 1 has been implemented in 10 geographic clusters (5 control and 5 intervention).
Locations: corresponds to physical locations. There are two types of locations: homesteads and TasP clinics.
Homesteads: the population lives in scattered homesteads that are not concentrated into villages or compounds. All usable and occupied homesteads were eligible for trial participation.
Households: each homestead coul be composed of one or several households. An household remains always attached to the same homestead.
Eligible individuals : all 16 years or older and resident household members. Each individuals is attached to an household. In case of internal migration, an individual could move to another household.
TasP clinics: dedicated trial clinics implemented in each survey cluster.

Sampling
Sampling Procedure
Randomisation (control clusters vs intervention clusters) was performed by the trial statisticians at the start of the trial for all clusters.
All individuals 16 years or older and resident member of a local household are eligible.

Frequency of Data Collection
A calendar round refers to the time period it took to implement one home-based HIV testing round in all the clusters. During the first phase of the trial, three calendar rounds were conducted in four clusters (first group, 8 months, 4 months, 4 months duration) and two calendar rounds in six clusters (second group, 6 months and 6 months).
Clinical data of HIV-infected patients followed in TasP clinics has been collected on a day-to-day basis.
