The death toll from the year-long Ebola outbreak in eastern Democratic Republic of Congo (DRC) has topped 2,000, according to government data released on Friday, which also showed the number of confirmed cases surpassed 3,000.
Ebola caused global alarm in 2014 when the world's worst outbreak began in West Africa, killing more than 11,300 people and infecting an estimated 28,600 as it swept through Liberia, Guinea and Sierra Leone.
Doctors Without Borders said those involved with stopping the spread of the virus must build trust with the local communities.
"Since the child was identified at the point of entry, there are no contacts in Uganda", Dr Joyce Moriku, the State Minister for Health in charge of Primary Health Care, said in the statement.
Because the 9-year-old Ebola victim passed through an official entry point this week, Ugandan health authorities believe she had no contact with any Ugandan.
The Ministry of Health (MoH) has on August 29, confirmed an "imported" Ebola case in Kasese District.
The symptoms are severe: high fever and muscle pain followed by vomiting and diarrhoea, skin eruptions, kidney and liver failure, internal and external bleeding.
The Associated Press reports that cases of cross-border contamination are uncommon because of stringent screening procedures in Uganda and Rwanda.
"Our commitment to the people of the Democratic Republic of the Congo is that we will work alongside them to stop the Ebola outbreak", said Tedros.
The WHO has declared the epidemic a "public health emergency of worldwide concern" and so far almost 200,000 people have been vaccinated.
In Uganda, the woman with Ebola was once remoted and transferred to an Ebola remedy unit the place she later died.
The latest case of Ebola in Uganda comes just a month after World Health Organization (WHO) and Uganda's Ministry of Health declared that the Ebola virus disease had been contained in Uganda.
The CMRE also said that, of the four confirmed deaths yesterday, two were in the community, which raises the risk of further disease spread.
People who are infected do not become contagious until symptoms appear, which is after an incubation period of between two and 21 days.
