Ebola gains access to the human body through broken skin or mucous membranes.
At present, however, Guinea is the worst-hit country since the latest outbreak.
This is the first outbreak of the deadly virus there since a 2013-2016 outbreak, which is considered the world’s worst.
The 2013-2016 outbreak spread across several West African countries.
The deadly pathogen has killed thousands of people during its latest outbreak and the WHO is concerned about the latest revival, especially amid the coronavirus crises.
The WHO Regional Director for Emergencies, Abdou Salam Gueye, said: ‘There are six neighboring countries in Guinea and we have carried out an assessment of preparedness.
“Two of the countries are not ready and one is borderless and there are three countries more or less ready.”
The countries bordering Guinea are currently unwilling to introduce mass Ebola vaccination programs.
Mr Gueye added: “Neighboring countries have agreed on cross-border cooperation and coordination to control the outbreak.”

The country currently has the capacity to vaccinate 100 people a day.
This will be the first time an Ebola vaccine has been distributed in the country.
Currently, 1604 people have been vaccinated in Guinea.
Bachir KantĂ©, an official at the Ministry of Health, said: “In the coming days we will be able to vaccinate more people to properly curb this pandemic.”
