Ebola outbreak may be spreading faster than first thought, WHO doctor warns

Residents in close proximity to the epicenter of an Ebola outbreak in the Democratic Republic of Congo's Ituri province, which has claimed 131 lives, have expressed their deep concerns regarding the crisis. A representative from the World Health Organization (WHO) cautioned that the spread of cases may be occurring at a rate faster than initially anticipated.

One local, identifying himself as Bigboy, communicated to BBC News about the rapid pace of fatalities among the infected, noting, "Ebola has tortured us." Current reports indicate that more than 513 suspected cases are being monitored in DR Congo, while one reported death has occurred in neighboring Uganda.

Dr. Anne Ancia of the WHO informed BBC News that ongoing investigations into the outbreak are revealing a concerning trajectory, with evidence suggesting that the virus has expanded into additional areas.

A recent analysis released by the MRC Centre for Global Infectious Disease Analysis based in London highlighted substantial under-detection of cases, estimating that the number of actual infections may exceed 1,000. The study emphasized that the current outbreak is "larger than currently ascertained" and that its "true magnitude remains uncertain."

Bigboy further noted the heightened fear among his community, as locals take precautionary measures such as handwashing with clean water, although there is a pressing need for additional protective supplies, including face masks. Another local resident, Alfred Giza, indicated that community members are awaiting delivery of face masks to combat the threat but expressed uncertainty regarding the actions to take should a family member contract the virus.

The Red Cross has issued a warning that Ebola outbreaks can escalate quickly if cases are not identified promptly, communities lack adequate information, and health systems are overwhelmed—conditions that are increasingly evident in the ongoing outbreak.

In a recent statement, DR Congo President Félix Tshisekedi called for "calm" amongst the population while urging vigilance following a crisis meeting. WHO Director-General Tedros Adhanom Ghebreyesus, who last week declared the outbreak an international emergency, expressed deep concern about the outbreak's "scale and speed."

Health officials fear that the outbreak may have been in progress for several weeks prior to its initial detection on 24 April. Currently, no vaccine is available for the strain of the Ebola virus causing this outbreak, although the WHO is evaluating potential protective pharmaceuticals.

In an interview with BBC Newsday, Dr. Ancia described Ituri province as a "very unsecured area with lots of movement of population," which complicates effective investigation and disease control efforts. She noted, "The more we are investigating this outbreak, the more we realize that it has already disseminated at least a little bit across border and also in other provinces."

The outbreak has also reached South Kivu province, which has faced longstanding humanitarian crises. A case in Goma, the largest city in eastern DR Congo, has raised alarm due to the population of about 850,000 and the presence of Rwandan-backed rebels.

The ongoing instability in several provinces facilitates frequent movement, thereby heightening the risk of the virus's transmission, according to Dr. Ancia. In response, several African nations are implementing enhanced border screening procedures and preparing their healthcare facilities. Notably, Rwanda has closed its borders with DR Congo, and Uganda has advised against physical contact such as hugging and handshaking.

An American citizen, reportedly Dr. Peter Stafford affiliated with a missionary group, is being evacuated from DR Congo after developing symptoms over the weekend. The German health ministry confirmed the transport of this US citizen for treatment. Additionally, the US Centers for Disease Control and Prevention (CDC) is coordinating the evacuation of at least six other Americans who were exposed to the virus.

The WHO and other entities are collaborating with local governments and communities to contain the virus's spread, urging residents to adhere to preventive measures and report any symptoms to nearby healthcare facilities.

What is Ebola and how does it spread?

Ebola is a viral infection that initially presents symptoms akin to the flu, including fever, headaches, and fatigue. As the illness advances, patients may experience vomiting, diarrhea, and potentially organ failure. While not all individuals develop internal or external bleeding, some do.

The virus spreads through direct contact with bodily fluids, such as blood or vomit, from infected individuals. The Bundibugyo strain responsible for the current surge in cases is uncommon and has previously led to only two outbreaks, with a mortality rate of approximately one-third of those infected.

The largest Ebola outbreak on record occurred between 2014 and 2016 in West Africa, affecting over 28,600 people and resulting in 11,325 fatalities. This outbreak was attributed to the Zaire strain, for which an approved vaccine exists. The disease spread across multiple countries, including Guinea, Sierra Leone, the United States, the United Kingdom, and Italy.
