Over half a million of Johannesburg’s 5.8 million people live in 181 informal settlements. The number of COVID-19 cases in the city increased rapidly from 971 on 6 May to 1,153 on 15 May, a jump of 20 per cent in less than 2 weeks. Shared water and toilet facilities make Johannesburg’s informal settlement residents extremely vulnerable to infection. Residents participating in the Asivikelane initiative have reported dire water and sanitation problems over the last 6 weeks. Their efforts to engage with the city have met with a slow response.
