Lindiwe Dumasile, a nurse and deputy secretary general of the Young Nurses Indaba Trade Union (YNITU), explains what happens when residents come across the tracer teams, who dress in full white protective gear and are often accompanied by police.

"When the government contact tracer teams visit nurses who have tested positive for Covid-19 and are under self-quarantine, [the nurses] are placed under a microscope in their communities," she said.

The supervisor then called police into my house, [but] because [I am] a health worker, the community members saw the police vans and assumed that this meant that I had contracted the virus, and this caused panic in my street.

Another voice note on WhatsApp circulated by a nurse in quarantine remarked on how she and another nurse in self-isolation were afraid of the tracer team visits.

The nurse said her colleague had turned away one of the tracer teams, telling them to rather "communicate telephonically" as she feared the ostracisation of her community.
