Kenya, which confirmed its first case of the virus on March 13, had tested a total of 55, 074 samples from different parts of the county by May 22.
At the same briefing in Machakos, Mr Kagwe announced that Kenya will no longer import Personal protective equipment (PPE) because local manufacturers are now able to produce quality gears for health workers.
Healthcare workers had raised concerns over the quality of the equipment donated to the counties by the national government.
Mr Maurice Opetu, the deputy secretary-general of the Kenya National Union of Nurses, said the equipment delivered to the health workers were of poor quality, hence putting them at high risk of contracting the virus.
Mr Kagwe called upon the management of the Covid-19 Fund, launched by President Uhuru Kenyatta, to release the money and start putting it in manufacturing of the equipment.
