Many LGBT people in Japan worry that catching the novel coronavirus could mean their sexual orientation is revealed against their will as authorities probe into infection routes, a supporters' group has found.

A survey by Marriage for All Japan also showed they worry about whether they or their partner will be able to receive important medical information that hospitals provide to family members if one of them becomes infected with the pneumonia-causing virus.

About 180 lesbian, gay, bisexual and transgender people among others had responded to the survey by Friday.
