The UN Children's Fund is helping rehabilitate and service medical oxygen plants at three main provincial hospitals, said Farhan Haq, the deputy spokesman for UN Secretary-General Antonio Guterres, on Friday.

The fund also reactivated the distribution of personal protective equipment, including about 400,000 masks, one million gowns, 855,000 gloves, 78,000 goggles, and 42,000 face shields, Haq added.

The WHO is restocking laboratories with test kits and monitoring Covid-19 variants, he said.

The UN team led by the resident coordinator, Beatrice Mutali, reported that in the last few weeks, Zambia had a positivity rate of seven per cent for Covid-19, Xinhua news agency reported.

The WHO said there was a general decline in the Covid-19 rate over the previous four weeks globally, including in the rest of Africa, where the number of cases was down 12 per cent over the last 28 days. Notably, there was an increase in the number of deaths from the disease reported in Africa.

However, the WHO added that comparing reported cases in different regions is not an accurate representation of infection rates due to reductions in testing and reporting globally.
