A health time bomb is brewing at most quarantine centres following the horrific and appalling conditions being experienced lately as more returnees trickle back home.

According to one of the returnees, some people in quarantine centres have exceeded the mandatory 21-day period but still yet to receive COVID-19 test results.

We were tested on Tuesday May 26 last week and were told that results will come within 48 hours, but some of us have nothing after eight days," said the returnee.

The returnees in quarantine centres are living in fear as more are testing positive.

Meanwhile minister of Home Affairs, Kazembe Kazembe and several government officials toured quarantine centres in Harare yesterday afternoon after a spate of protests last week over the deteriorating conditions at the centres.
