Ebola: 5 Things To Know About Bundibugyo Strain As Nigeria Confirms First Case

Nigeria has confirmed its first case of Ebola virus disease caused by the Bundibugyo strain, raising concerns about the symptoms, transmission, treatment and prevention of the potentially deadly infection.

The World Health Organisation (WHO) confirmed on Tuesday that the patient was a woman with a recent travel history to Uganda.

The patient is receiving medical care in isolation in Abuja, while 44 contacts had been identified and were being monitored to prevent further transmission.

The Bundibugyo strain is a distinct type of Ebola virus that has previously caused outbreaks in parts of Africa.

As health authorities intensify surveillance and response efforts, here are five things to know about the Bundibugyo Ebola strain.

1. Bundibugyo Is A Distinct Ebola Virus Strain

The Bundibugyo virus is one of the viruses that cause Ebola virus disease in humans. It was first identified during an outbreak in Bundibugyo District, Uganda, in 2007. The virus is different from the Zaire ebolavirus species, which has been responsible for several major Ebola outbreaks. The distinction is important because vaccines and treatments developed for one Ebola virus species may not be effective against another.

2. Symptoms Include Fever, Weakness And Diarrhoea

Symptoms of Bundibugyo Ebola may initially resemble those of other infectious diseases, making early detection important. Common symptoms include fever, severe weakness, fatigue, headache, muscle pain, abdominal pain, vomiting and diarrhoea. In severe cases, the disease can cause complications affecting vital organs, and some patients may experience bleeding. However, bleeding does not occur in every case. People who develop compatible symptoms after possible exposure should seek immediate medical attention and inform healthcare workers about their recent travel history or contact with a suspected case.

3. Ebola Spreads Through Contact With Infected Bodily Fluids

The Bundibugyo virus can spread through direct contact with the blood and other bodily fluids of an infected person who is experiencing symptoms. Transmission can also occur through contaminated objects and contact with infected animals. The virus can enter the body through broken skin or the eyes, nose and mouth. Healthcare workers and family members caring for infected people may face an increased risk of infection if appropriate protective measures are not followed. The incubation period for Ebola ranges from two to 21 days. This means symptoms may take up to three weeks to develop after infection.

4. No Licensed Vaccine Or Specifically Approved Treatment For Bundibugyo Ebola

Unlike Ebola disease caused by the Zaire ebolavirus species, for which licensed vaccines and treatments are available, there are currently no licensed vaccines or specifically approved therapeutics for Bundibugyo virus disease, according to the WHO. However, supportive medical care remains essential in managing the infection and improving patients’ chances of recovery. Treatment may include intravenous fluids, correction of electrolyte imbalances, oxygen support, nutritional support and management of complications. Researchers have also identified candidate vaccines and treatments for evaluation in clinical trials. These include the antiviral drug remdesivir and experimental monoclonal antibodies. Such candidates should not be mistaken for established, specifically approved treatments for Bundibugyo Ebola.

5. Early Detection And Prevention Are Critical

Preventing the spread of Bundibugyo Ebola requires early identification of suspected cases, prompt isolation, contact tracing and monitoring of people who may have been exposed. Members of the public can reduce their risk by washing their hands regularly, avoiding contact with the blood and bodily fluids of suspected or confirmed cases, and refraining from handling sick or dead wild animals. Anyone who develops symptoms after possible exposure should seek medical attention promptly and provide accurate information about recent travel and contact with infected people.

The Nigeria Centre for Disease Control and Prevention (NCDC) and the WHO remain important sources of official updates on the outbreak, including case numbers, contact tracing and public health guidance.
