Ebola strain with no vaccine, no cure and a 30% kill rate | World | News
An Ebola outbreak in the Democratic Republic of Congo has been spreading unnoticed for weeks in one of the harshest environments on Earth, and experts are watching closely to see if the outbreak can be contained before it turns into something much more serious.
Approximately 250 suspected cases and 80 deaths have been recorded so far. The World Health Organization has declared the situation a public health emergency of international concern, but scientists are at pains to emphasize that this does not mean the world is in the early stages of a Covid-style pandemic.
How dangerous is the Congo Ebola outbreak?
For most of the world, the immediate threat is limited. At the height of the 2014-2016 West African outbreak, the largest in history with 28,600 infections, Britain recorded just three cases, all of them medical volunteers traveling to help with the response.
Dr. from Oxford University Institute of Pandemic Sciences. Amanda Rojek said the WHO’s emergency declaration “reflected that the situation was complex enough to require international coordination” but was far from suggesting that a global crisis was imminent.
The countries most exposed are those that share borders and economic ties with the Democratic Republic of Congo. Experts found Uganda, South Sudan and Rwanda to be particularly vulnerable, given the volume of cross-border movement between them and the affected region. Two people in Uganda have been confirmed to have contracted the virus, and one of them has died.
What makes this Ebola outbreak different?
The BBC reported that the strain at the center of this crisis is Bundibugyo, one of the least understood of the three strains of Ebola known to cause outbreaks in humans. Before this, it appeared only twice in recorded history; the first in 2007 and the other in 2012, with a mortality rate of about 30 percent.
Unlike more commonly encountered strains of the virus, there is no approved vaccine or drug treatment for Bundibugyo, although some experimental options are available.
Standard diagnostic tests proved unreliable in identifying this species, with initial samples yielding negative results, and only after more advanced analysis were scientists able to confirm that Bundibugyo was responsible. Prof Trudie Lang, from the University of Oxford, described dealing with this species as “one of the key concerns” in the current situation.
What are the symptoms of Ebola?
The incubation period varies from two days to three weeks. In its early stages, the disease can easily be confused with the flu, causing fever, headache and fatigue, later progressing to severe gastrointestinal symptoms, multiple organ failure and, in some cases, uncontrollable bleeding, both internal and external.
Because there is no approved medication to target Bundibugyo, treatment focuses on what experts describe as “optimized supportive care” to manage pain, treat secondary infections, and maintain fluid and nutrition.
The earlier the patient is intervened, the greater the chance of survival. Transmission requires direct contact with bodily fluids, including blood, vomit, and similar secretions, from an already symptomatic person; This limits but does not eliminate the risk of rapid spread.
Why was the Ebola epidemic detected so late?
The first known case was a nurse who fell ill on April 24. It then took three weeks for the epidemic to be officially declared; This delay alarmed experts. Dr. from Imperial College London. Mother Cori said: “The transmission has been going on for several weeks and the outbreak was detected very late, which is worrying.”
WHO warned that late detection indicates “a potentially much larger outbreak than currently detected and reported.”
Can the Congo Ebola epidemic be brought under control?
Health authorities are now urgently working to identify infected individuals and trace their contacts; It also works to prevent transmission in hospitals and treatment centers where patients are most contagious and to provide safe burials as bodies have the ability to spread the virus.
The mission is complicated by conditions on the ground. Active conflict in the region has forced a quarter of a million people from their homes, creating chaotic conditions in which a virus can move quickly and invisibly. Prof Lang warned: “Many of the affected areas are mining towns with highly mobile and transient populations. This mobility increases risk as people move between communities and across borders.”
But there are reasons for cautious optimism. The Democratic Republic of Congo has more experience fighting Ebola than almost any other country in the world, having faced 17 outbreaks since the virus was first identified there in 1976. Dr. from the London School of Hygiene and Tropical Medicine. Daniela Manno said the country’s response was “much stronger today than it was ten years ago.”
Whether this epidemic will be brought under control quickly or turn into a much more serious situation will depend entirely on the decisions to be made in the coming days and weeks.
