The tally of individuals with suspected and confirmed instances of Ebola in central Africa is rocketing upwards with surprising pace — from 256 instances on 16 Might to roughly 1,000 as of 27 Might. In line with the World Well being Group (WHO), some 240 individuals have died — and the outbreak reveals no indicators of slowing down (see ‘Ebola’s surge continues’).
However specialists say that they’ve instruments to assist to manage the outbreak, which is for now confined to the Democratic Republic of the Congo (DRC) and Uganda, because of hard-won experience gained throughout earlier Ebola epidemics.

The DRC, which is the epicentre of the present outbreak, has contended with a number of outbreaks of Ebola over time, notes Chima Ohuabunwo, an epidemiologist at Morehouse Faculty of Medication in Atlanta, Georgia. Because of this, the DRC is without doubt one of the world’s most skilled international locations in dealing with the virus species that trigger the illness. “We ought to be in a greater place to reply” than throughout earlier outbreaks, Ohuabunwo says.
One problem is that there’s neither a vaccine nor a focused remedy for the particular virus inflicting this outbreak, the Bundibugyo species of ebolavirus. Which means different measures might be wanted to cease the virus’s march. Listed here are a few of the measures that specialists suggest.
Improve testing and call tracing
Ramping up the laboratory capability to diagnose Ebola is crucial to rapidly figuring out who’s contaminated in order that they are often remoted earlier than they unfold the virus to others, says Robert Garry, a virologist at Tulane College in New Orleans, Louisiana. Garry helped to reply to the biggest Ebola epidemic on report, which induced greater than 11,000 deaths in West Africa between 2014 and 2016.
However the present outbreak is straining the area’s testing capability. “My understanding is that the primary laboratory doing the exams is struggling” to maintain up, says Garry. Of the 1,038 instances that had been reported by 27 Might, 132 had been confirmed by lab testing because the Bundibugyo species. The DRC’s Ministry of Public Well being, Hygiene and Prevention didn’t reply instantly to a request for remark.
In line with the WHO, lab testing capability is already being scaled up. The biotechnology firm BioFire Protection in Salt Lake Metropolis, Utah, which produces a extremely delicate take a look at that may detect a number of Ebola species, together with Bundibugyo, introduced on 19 Might that it’s growing its manufacturing capability.

Garry notes that utilizing fast antigen exams — much like the know-how used within the widespread residence exams for COVID-19 — might additionally assist, though they aren’t designed to detect the Bundibugyo species and may need a low specificity. “Should you take a look at sufficient individuals, it’s going to assist you to with the surveillance and you are able to do that in 10–quarter-hour. You don’t want a laboratory or costly infrastructure,” he says.
Extra testing capability can be wanted for an intervention referred to as contact tracing, through which public-health employees determine people who may need been uncovered to an contaminated particular person. These contacts are then additionally requested to check and to restrict their actions. Well being employees advise contacts about indicators of an infection and proceed to examine on them, which builds belief within the well being system.
Alongside testing, contact tracing is essential to controlling the outbreak, public-health consultants say, and is normally step one in the direction of containing a virus. “If we don’t do this, you’re mainly preventing a shedding battle as a result of the instances will proceed to develop,” says Salim Abdool Karim, an epidemiologist who chairs the Emergency Consultative Group of the Africa Centres for Illness Management and Prevention in Addis Ababa.
Almost two weeks after the outbreak was declared, contact tracing has but to begin in lots of cities the place Ebola instances are suspected or confirmed, say health-care specialists within the DRC’s Ituri province, the supply of a lot of the instances to date. “We’ve not seen anyone come to supply technical assist” and run contact tracing, says Tony Ukety, medical director of the Tropical Illness Analysis Centre in Rethy, in Ituri province.
Present supportive care
Even within the absence of particular medication for the Bundibugyo species, satisfactory supportive care can drastically improve the survival probabilities of contaminated individuals, specialists say. Through the West Africa Ebola epidemic in 2014–16, the chance of demise inside a month of symptom onset was 74% decrease for individuals who had been hospitalized with Ebola than for many who didn’t obtain any medical remedy, in accordance with an evaluation1 of round 600 instances reported in Liberia in 2014.
