A five-year-old boy has died after being treated for Ebola in Uganda, central Africa.
It is the first confirmed fatality in that country since an , AFP reported.
The boy was taken to a hospital in Uganda after he began vomiting blood and exhibited other symptoms of the deadly virus.
Reports say the boy had travelled across the border with his mother and father on Sunday.
His mother had returned to Congo to nurse her father, who died of the disease, the health minister Jane Aceng said.
Four of the boy's relatives are being monitored in isolation wards and two of them are being tested for Ebola after exhibiting symptoms of the disease.
Disease experts say there has been a troubling spike in new cases in recent weeks.
More than 2,000 people have died in the latest outbreak over the last 10 months - making it the second biggest in history.
Most people who contract the disease will die from their symptoms with a terrifying 67% fatality rate being reported.
The country's health minister said on Twitter: "Uganda has been in preparedness mode ever since the Ebola outbreak was declared in DRC.
"Now, we move into response mode.
"Please cooperate with our health, immigration and security officials to ensure effective screening to prevent spread of Ebola to other parts of the country."
Uganda's worst Ebola outbreak was in 2000 when 425 people were infected. More than half of them died.
"This is the first confirmed case in Uganda during the Ebola outbreak on-going in neighbouring Democratic Republic of the Congo," the WHO said in a statement.
Preparing for possible cases of Ebola, Uganda has vaccinated nearly 4,700 health workers, disease monitoring has been intensified, special treatment units set up and health workers have been trained to recognize symptoms of the disease, WHO said.
More than 11,000 people died when a similar outbreak occurred in in West Africa between 2013 and 2016.
