Abstract
Background
HIV self-testing (HIVST) addresses barriers to HIV diagnosis among men, but current
approaches to distributing HIVST kits only reach a subset of the men requiring testing.
Methods
We conducted a pilot trial of the secondary distribution of HIVST kits through peer networks
in fishing communities of Buliisa district (Uganda). We recruited distributors (“seeds”)
among male patients of a health facility, and among community members. Seeds were
trained in HIVST and asked to distribute up to five kits to their peers (“recruits”). Recruits
were referred to the study using a coupon, and asked to return the HIVST kit (used or
unused). The accuracy of HIVST was measured against a confirmatory test conducted by a
health worker. We conducted audio computer assisted self-interviews to measure the occurrence of adverse events, and evaluate the potential yield of peer-delivered HIVST. We also
assessed how seeds and recruits rated their experience with peer-distributed HIVST.
Results
Nineteen seeds offered an HIVST kit to 116 men, and 95 (81.9%) accepted the offer. No
recruit reported coercion, but two seeds experienced hostility from recruits or their family
members. The sensitivity of peer-distributed HIVST, as interpreted by recruits, was 100%,
and its specificity was 92.8%. Among recruits, 29 had never tested (25.8%), and 42 (44.2%)
had tested more than a year ago. Three men living with HIV learned their status through
peer-distributed HIVST (yield = 1 new diagnosis per 6.3 seeds). Most recruits (85/88) and
seeds (19/19) reported that they would recommend HIVST to their friends and family. All
seeds stated that they would accept acting as peer distributors again.

Uptake of HIV self-testing among fishermen
Competing interests: The authors have declared

Conclusions
This novel peer-based distribution model of HIVST is safe, and has high uptake. It could
help reduce the gender gap in HIV testing in under-served fishing communities in Uganda
and elsewhere.
Introduction
Significant numbers of persons living with HIV remain undiagnosed in African countries [1].
To end the HIV/AIDS epidemic by 2030, new HIV testing strategies must be explored. In particular, strategies that reach men living with HIV (MLWH) are needed [2], since MLWH are
less likely to use existing testing services than women [3–5]. Novel HIV testing strategies may
contribute to ending the HIV/AIDS epidemic by reaching hard to reach groups that continue
to contribute to gaps in HIV status knowledge as well as being drivers of HIV transmission.
One potential strategy is HIV self-testing (HIVST), i.e., an individual performing his/her
own HIV test [6–10]. HIVST is accurate, convenient and confidential [6, 11–13]. It may foster
repeat testing [7], but strategies to reach undiagnosed MLWH with HIVST remain underdeveloped. Current models include distributing HIVST kits at health facilities, or during home
visits by health workers [6]. These approaches may miss MLWH who seldom attend health
facilities, or who are absent from home for work-related or other reasons. Thus, alternate distribution mechanisms for HIV self-testing targeting MLWH need to be explored.
Several studies have also investigated the secondary distribution of HIVST kits. In this
model, some individuals are given kits to distribute to members of their social networks. Most
such studies have mobilized women as distributors of HIVST kits: clients of antenatal care
clinics have been asked to distribute HIVST kits to their partner [14] and female sex workers
(FSW) have been asked to enroll their male clients [14, 15]. Despite being safe and effective,
these approaches only reach a subset of the MLWH who require testing.
We recruited men as distributors (or “seeds”), and asked them to offer HIVST kits to their
peers. This approach has been used among men who have sex with men [16], but not in other
high-risk groups of men. Potential concerns include an increased incidence of coerced testing
[17]. We thus measured the safety, uptake and potential yield of this strategy in several fishing
communities in Uganda.
Methods
We conducted a single-arm pilot trial of the peer-based distribution of HIVST kits in 4 fishing
communities of Buliisa district, on the shores of Lake Albert. As in other fishing communities
in Uganda [18], HIV risk is high, but HIV testing is limited [11]. The institutional review
boards of Johns Hopkins University, the AIDS Support organization and the Uganda National
Council for Science and Technology approved the study.
We translated materials detailing HIVST procedures into the local language (Runyoro). We
developed standardized scripts (S1 ScriptEng) to help men 1) introduce HIVST to peers, 2)
address misunderstandings and 3) troubleshoot conflictual situations that may arise during
the distribution of HIVST kits. We then recruited seeds among a) patients receiving antiretroviral treatment at a local facility of the AIDS Support Organization (TASO), b) clients of other
services (e.g., HIV testing and counseling) or c) community members. Seeds had to be (...truncated)
