Ebola in Congo: WHO declares international health emergency, amid growing concern over the Bundibugyo strain, with no vaccine or specific treatment available.

The epidemic of Ebola in the Democratic Republic of the Congo continues to worsen and has now reached an international level of alert. The number of victims has risen to 131 dead, while suspected cases have exceeded the quota 500, according to data reported by the World Health Organization. The speed with which the virus is spreading, combined with the uncertainty about the true extent of the outbreak, has prompted the WHO Director General, Tedros Adhanom Ghebreyesus, to declare the event a public health emergency of international concern, known as Pheic.

An extraordinary decision before the emergency committee

The WHO's decision marks a particularly significant step in the management of the crisis. Tedros explained that he made the decision after consulting with the health ministers of the affected countries, emphasizing his "deep concern" over the scale and speed of the outbreak. The declaration of an international emergency is the second-highest alert level established by the World Health Organization, although it does not currently constitute a pandemic. According to the WHO, the situation does not meet the criteria for a pandemic emergency, but it still poses a concrete risk to regional and international public health.

The outbreak in Ituri and the spread to new areas

The epicenter of the epidemic is located in the eastern province ofIturi, in the north-east of the Democratic Republic of Congo, bordering Uganda and South Sudan. The first reports have come from areas such as Mongwalu e Rwampara, mining areas affected by intense population movements. Subsequently, health authorities also identified infections in new locations, including Nyakunde, still in Ituri, Butembo in North Kivu and the city of Rubber, one of the main urban centers in the east of the country. The presence of the virus in different areas makes contact tracing more difficult and increases fears of a wider spread than has been detected so far.

The virus crosses the Congolese border

The crisis is no longer limited to the Democratic Republic of Congo. Even in Uganda Cases of Ebola have been confirmed, including at least one death. According to information released by the U.S. Centers for Disease Control and Prevention, the cases recorded in Kampala involve people from the Democratic Republic of the Congo. Cross-border spread is one of the factors that most influenced the WHO's assessment, especially since neighboring countries are exposed to high risk due to population mobility, trade links, and persistent epidemiological instability.

Bundibugyo strain worries experts

Making the situation even more delicate is the strain responsible for the current epidemic: the Ebola virus BundibugyoThis is a rare variant, which has already appeared in previous outbreaks in Uganda and the Democratic Republic of Congo, but for which there are currently no tests. approved vaccines or specific therapiesUnlike the Zaire strain, against which vaccines are available, Bundibugyo poses a more complex challenge for health authorities. The lack of targeted preventive tools requires focusing primarily on isolation, surveillance, contact tracing, and the safe management of suspected cases.

The number of confirmed and suspected cases is growing.

The number of deaths attributed or suspected to the epidemic continues to rise. Health authorities have reported hundreds of suspected cases and dozens of deaths already reported in the early stages of the outbreak, with the death toll now rising to over one hundred. The WHO has highlighted the significant uncertainty surrounding the true number of infected people and the true geographic spread of the outbreak. According to experts, the high positivity rate of the initial samples analyzed and the confirmation of cases in multiple countries indicate the possibility that the epidemic is more widespread than officially available data.

The American doctor tested positive and the US citizens exposed

The emergency has also affected U.S. citizens. Six Americans have come into contact with infected people in Congo, but are currently showing no symptoms. The most serious case is Peter StaffordAn American doctor working in Congo with a missionary organization has tested positive for the Bundibugyo strain after developing symptoms over the weekend. The patient will be transferred to Germany for specialized care, while the other six American citizens exposed to the virus will be quarantined and monitored. Germany has confirmed its willingness to accept the doctor at the request of U.S. authorities.

The US response and Trump's comment

In the United States, the situation is being closely monitored, also due to the presence of American citizens involved in health activities in the affected areas. The president Donald Trump He stated that, for now, the epidemic remains limited to Africa, while acknowledging the increase in cases. American health authorities have strengthened surveillance and contact tracing procedures, while attention remains focused on patient contacts and travelers from high-risk areas. The priority indicated by experts is to prevent any imported cases from generating new chains of transmission.

Italy activates health surveillance for operators and aid workers

even the Italian Ministry of Health The Ministry has adopted precautionary measures. In a circular, the Ministry ordered the activation of health surveillance for personnel of government, non-governmental, and cooperative organizations employed in the areas affected by the outbreak, coming from all territories of the Democratic Republic of the Congo and Uganda. This decision was motivated by the uncertainties regarding the size and geographical spread of the epidemic, the potential severity of the infection, and the lack of vaccines or specific therapies against the Bundibugyo strain.

Checks, health forms and traceability of returns

The Italian circular provides for a health declaration form to be submitted to the ministry at least 48 hours before departure from affected areas. The document must certify, via a self-declaration, that the returning person is symptom-free. A medical history form is also required to be completed as part of the primary screening, including body temperature measurement and assessment by health personnel from the maritime, air, and border health offices. As a precaution, the same screening may also be applied to workers who have not reported any known exposure in the previous 21 days, or for whom the risk of contact cannot be definitively reconstructed.

Airlines asked to report suspected cases

The ministry also recommended that airlines promptly report to the relevant health authorities any onboard situations that suggest an infectious disease. The collection of Passenger Locator Forms, which are essential for contact tracing in the event of a medical emergency, remains crucial. The WHO, however, does not recommend border closures or widespread travel and trade restrictions, but rather calls for accurate information for travelers, support for affected countries, and facilitation of the evacuation or repatriation of exposed citizens.

How Ebola is transmitted and why tracing is crucial

The Ebola virus causes a severe hemorrhagic fever and is transmitted through direct contact with the blood, body fluids, and tissues of infected people or animals. The incubation period generally varies from 2 to 21 daysInitial symptoms may include fever, severe weakness, muscle aches, headache, and sore throat, followed by vomiting, diarrhea, dehydration, and, in more severe cases, internal and external bleeding and multiple organ failure. According to the epidemiologist Massimo Ciccozzi, contact tracing, and quarantining potentially exposed people are critical tools to contain the virus before it becomes harder to stop.

The burden of war and health fragility

Managing the epidemic is made even more complex by the situation in the eastern Democratic Republic of the Congo, a region marked by instability, the presence of armed groups, logistical challenges, and fragile health infrastructure. The mining areas of Ituri, crisscrossed by the constant movement of workers and communities, represent a particularly vulnerable context. According to experts, wars and humanitarian crises favor the spread of infections because they make it more difficult to isolate the sick, protect health workers, ensure timely treatment, and convince the population to comply with health protocols.

Reporting delays and local beliefs

Epidemiological investigations are still ongoing to identify the origin of the outbreak. Among the critical factors reported by the authorities is the delay in detecting the first cases, partly due to the fact that some communities initially attributed the symptoms to a mystical illness or witchcraft. This may have pushed some patients to turn to prayer centers rather than health facilities, delaying diagnosis, isolation, and care. In an Ebola epidemic, even a few days' delay can significantly impact the ability to contain the contagion chain.

The risk associated with funerals and the management of bodies

One of the most delicate moments in the transmission of the virus concerns the management of victims' bodies. African health authorities have drawn attention to funerals, which in the past have been a significant factor in the spread of the virus due to direct contact with the bodies of the deceased. Safe burial procedures are therefore considered essential to prevent new infections. Compliance with health protocols, however, must contend with local traditions, distrust of institutions, and operational difficulties in more isolated areas.

An emergency that must be contained before it becomes a regional one.

The immediate objective of international health authorities is to rapidly contain the outbreak, strengthen surveillance in neighboring countries, and ensure adequate facilities for isolation and patient care. The current outbreak is the seventeenth recorded in the Democratic Republic of the Congo since the virus was discovered in 1976. The memory of major past epidemics, particularly that in West Africa between 2014 and 2016 and that in Congo between 2018 and 2020, remains a warning to the international community. While it is not currently a pandemic, the WHO's warning indicates that the window to stop the spread of the Bundibugyo strain must be exploited with speed, coordination, and the utmost caution.
