Data on intermediate nodes linking HIV-negative nodes of sexual partners to the closest HIV-positive nodes.

Variablea			Total HIV-negative sexual partners (n=160), n (%)		Tested sexual partnersb (n=124), n (%)		Untested sexual partnersc (n=36), n (%)
Not linking to any HIV-positive node			117 (73.1)		106 (90.6)		11 (9.4)
Linking to the closest HIV-positive node			43 (26.9)		18 (41.9)		25 (58.1)
	Directly	13 (30.2)		3 (16.7)		10 (40.0)
	Through 1 intermediate node	11 (25.6)		7 (38.9)		4 (16.0)
	Through 2 intermediate nodes	16 (37.2)		5 (27.8)		11 (44.0)
	Through 3 intermediate nodes	3 (7.0)		3 (16.7)		0 (0)

^aEach node was calculated at the closest distance to an HIV-positive node; the calculation was not repeated.

^bThose who were referred through the Line app and completed the rapid HIV test by our trained staff.

^cThose whose accounts and profiles on social media platforms where they first met the referrer were disclosed by the referral to our staff.
