Nigeria has confirmed an Ebola case in a woman who travelled from Uganda to Abuja, prompting health authorities to launch contact-tracing measures to prevent further transmission.

Health Minister Muhammad Ali Pate said laboratory tests confirmed the infection. The patient has been admitted to a hospital in Abuja, where she is being isolated and receiving medical treatment.

Authorities have identified 44 close contacts of the woman and begun monitoring them as part of efforts to contain the potential spread of the virus.

The case places Nigeria on alert as health officials work to determine whether the infection has spread to other people. Nigeria is the first West African country reported to have recorded a case linked to the current Ebola outbreak in East Africa.

The development comes as the country draws on its experience managing an earlier Ebola outbreak in 2014, when health authorities successfully contained the virus through surveillance, isolation and contact-tracing measures.

Ebola is a severe viral disease that can cause fever, vomiting, diarrhoea and, in some cases, internal or external bleeding. Severe infections can lead to organ failure and death.

The virus spreads through direct contact with the blood or other bodily fluids of an infected person, as well as contaminated materials. Early identification of suspected cases and the isolation of infected individuals are essential to limiting transmission.

The latest case also raises concerns about the wider regional impact of Ebola outbreaks. According to the European Centre for Disease Prevention and Control, an outbreak in the Democratic Republic of Congo that began in May has recorded more than 9,500 cases and at least 4,600 deaths.

Health authorities are expected to continue monitoring the identified contacts and investigating the patient's movements to establish whether additional infections have occurred.

The situation underscores the importance of cross-border disease surveillance and rapid public health responses in preventing outbreaks from spreading between countries.
