DAKAR, Senegal (AP) \u2014 The fastest-growing Ebola outbreak<\/a> in history has killed more than 1,000 people<\/a> in eastern Congo as health officials race to contain a virus with no approved vaccine or treatment.<\/p>\n An update from Congo\u2019s public health institute on Wednesday said there have been 2,536 confirmed Ebola cases and 1,033 deaths, with at least 738 patients in isolation or hospitalized.<\/p>\n The outbreak<\/a> declared on May 15 is unlike most previous instances of Ebola spreading through communities because the Bundibugyo virus responsible has no approved vaccines or treatments.<\/p>\n It is mostly concentrated in remote Ituri province, which accounts for nearly 90% of cases, but there have been others confirmed in five provinces including one of Congo\u2019s largest cities, Kisangani, and in neighboring Uganda.<\/p>\n Here is what to know about the outbreak:<\/p>\n Outbreak is spreading despite signs of slowing<\/p>\n While Congolese officials say the sharp rise in cases appears to be slowing, they caution the outbreak has not yet peaked. The latest report by the country’s public health institute says transmission remains sustained, with recent fluctuations in cases likely influenced by reporting delays and ongoing data consolidation.<\/p>\n Contact tracing continues to lag, with only around 77% of known contacts monitored nationwide, well below the 95% target health officials say is needed to interrupt transmission.<\/p>\n Responders are struggling to understand how far the Ebola outbreak has spread<\/a> and how much worse it might become.<\/p>\n U.S. Centers for Disease Control and Prevention researchers last month used computer modeling and found that in a worst-case scenario, the current Ebola outbreak could approach the worst in history.<\/p>\n The West Africa epidemic in 2014-2016 caused more than 11,000 deaths and took about eight months from the first case to reach 1,000 deaths.<\/p>\n The new outbreak\u2019s origin is still a medical mystery. The vast majority of cases are emerging from unknown chains<\/a> of transmission, the World Health Organization said.<\/p>\n Risk of the outbreak spreading globally remains low<\/p>\n The WHO continues to assess the risk from the outbreak as \u201cvery high\u201d inside Congo and \u201chigh\u201d in Uganda and neighboring countries, citing cross-border spread, frequent population movement and ongoing transmission in eastern Congo.<\/p>\n The agency says the global risk of spread is low, noting Ebola spreads through direct contact with the bodily fluids of an infected person rather than through the air, making it much harder to spread than respiratory viruses.<\/p>\n While WHO says additional imported cases are likely as the outbreak grows, those cases have so far been rapidly detected and contained without leading to sustained transmission outside the affected region.<\/p>\n The CDC echoed that assessment in its latest situation report, saying Ebola doesn\u2019t spread like respiratory viruses such as flu or COVID-19.<\/p>\n \u201cYou cannot get Ebola from being near someone,\u201d the agency said.<\/p>\n The CDC also notes that people infected with Ebola are not contagious until they develop symptoms, making case identification and contact tracing easier than with diseases that spread before symptoms appear.<\/p>\n The outbreak has spread little beyond Congo<\/p>\n The vast majority of Ebola cases are concentrated in Congo.<\/p>\n In neighboring Uganda, 20 cases have been confirmed, including two deaths. All cases were linked to imported infections from Congo and are concentrated in the capital Kampala. No new Ebola cases have been reported since June 21 and the WHO has discharged its final patient, beginning the 42-day countdown used to declare the end of an outbreak.<\/p>\n A positive case of Ebola was identified in France<\/a> in a doctor traveling from Congo in June. He has since fully recovered and was discharged from the hospital earlier this month.<\/p>\n The United States currently bars most recent travelers from Congo from entering the country and requires U.S. citizens to spend 21 days outside Congo before returning, while travelers from neighboring Uganda and South Sudan who are allowed to enter are routed through designated airports for Ebola screening.<\/p>\n U.S. plans to build an Ebola quarantine facility<\/a> in Kenya for Americans evacuated from Congo have been met with legal challenges and a series of protests<\/a> in Kenya, including some that have turned violent.<\/p>\n Community resistance and lack of testing slow response<\/p>\n Lack of trust and resistance from locals remain one of the biggest obstacles to containing the outbreak, according to authorities and health workers.<\/p>\n Rumors about Ebola treatment centers<\/a>, fears of isolation and resistance to safe burials have led some people to avoid testing or seek care only after becoming critically ill.<\/p>\n The response also has been hampered by conflict. Fighting involving the Rwanda-backed M23 rebels<\/a>, attacks by the Islamic State-linked Allied Democratic Forces<\/a> and mass displacement have complicated surveillance, contact tracing and access to affected communities.<\/p>\n At least 16 people were killed in an attack Wednesday by suspected ADF rebels in a village in Ituri province, local authorities said Thursday.<\/p>\n Unlike previous Ebola outbreaks, the Bundibugyo virus driving the epidemic has no approved vaccine or treatment. Although testing capacity has expanded since the outbreak began, responders say the virus continues to spread faster than they can contain it.<\/p>\n \u201cThere\u2019s never been an Ebola outbreak that started with so many cases because it was so late to be identified,\u201d said Trish Newport, emergency program manager for M\u00e9decins Sans Fronti\u00e8res (Doctors Without Borders), who has been working in Congo.<\/p>\n
