The Ministry of Health has so far distributed 13 million free face masks.
However, the Minister of ICT and National Guidance Judith Nabakooba in a Sunday statement noted that some companies which won contracts to supply these masks were distributing substandard products.
"The distribution started in July with the border and high-risk districts. Recently distribution also started in Kampala, Wakiso, Mukono, and other areas as well. So far, more than 13 million masks have been given out and some of the people who received can be seen putting them on," the minister said.
"However, the government is getting feedback that some of the masks being produced by some of the companies contracted are of poor quality and do not meet the standards issued by the Ministry of Health."
On that note, the minister said, investigations are underway and culprits will be punished.
"This is a big disappointment on the side of the suppliers entrusted with the responsibility of producing quality face masks meant to save lives of Ugandans," she said.
"Government is going to follow up with the respective suppliers and those found guilty of producing substandard masks are at risk of having their contracts canceled."
As part of the government's effort to prevent the spread of COVID-19, President Museveni instructed the Ministry of Health to avail free face masks to all Ugandans above the age of six.
The distribution started in July with the border and high-risk districts.
"I want to assure the public that the government is committed to ensuring that all Ugandans have access to free and good quality masks. I also call upon residents in all those areas that have not yet received masks to remain calm," the minister said.
"Efforts are underway to have them delivered to your respective local governments."
Uganda has so far registered 2,263 cases of the coronavirus, 1226 recoveries, and 19 deaths.
