This week, it reached Uganda, where three cases were recorded, all in people who had arrived from Congo.
"The regions of Kagera, Mwanza and Kigoma (northwest) are the most threatened, but since this disease is very easily and quickly transmitted from one person to another, nearly the entire country is at risk", the minister said.
"The Rapid Surveillance and Response Team has examined the patient at Kericho who had travelled from Malaba town on the Kenya-Uganda border who is in stable condition and confirms that she does not meet the case definition for Ebola".
The President was on Monday meeting World Health Organization (WHO) Director General, Dr. Tedros Adhanom at State House, Entebbe. "Allow me to repeat to Kenyans that the patient does not meet the case definition of Ebola", said Sicily Kariuki, while touring the Nairobi worldwide airport to see how arriving passengers are screened for symptoms of fever.
The development follows last week's confirmation that Ebola had spread from DR Congo to Uganda where two people have since died from the virus.
President Museveni said after meeting with World Health Organization director general Tedros Adhanom Ghebreyesus in Entebbe on Monday that the situation had been contained.
The patients who died in Uganda had reportedly visited a relative in the Democratic Republic of Congo who was diagnosed with Ebola.
Only four emergencies have been declared in the past decade, including the worst ever Ebola outbreak, which hit West Africa in 2014-2016.
"From our side, I would like to pledge that we will continue mobilizing global and regional support to control this outbreak as soon as possible".
Yesterday the DRC's ministry of health said two health workers, including one in Rwampara and one in Musienene, were newly diagnosed with Ebola.
"We have the capacity to establish Ebola screening centers and install health officials away in rural areas".
