Obadiah Moyo told the state-owned Herald newspaper that all test kits have to be evaluated by the local authority first, to establish efficacy and to avoid false results.

Private companies, including some pharmacies, have been selling rapid testing kits.

Zimbabwe has recorded nine positive cases of the virus from around 340 tests, with one death. The government says it is only conducting tests among those who display coronavirus-like symptoms.

Zimbabwe began a 21-day lockdown on 30 March, but the government appears to be easing some restrictions. On Friday, it reversed a ban on the sale of alcohol from supermarkets, even though liquor stores and bars remain shut.

President Emmerson Mnangagwa also announced that farmers and traders will be allowed to bring in their fresh produce to markets.

This came after social media videos showing police seizing and destroying vegetables caused an outcry.
