This gap suggests the virus circulated undetected for several weeks, likely amid clusters of unexplained illnesses and deaths that had not yet been linked to Ebola.
The situation is evolving quickly, and different reports reflect data collected at different moments.
Health officials emphasize that confirmed counts typically lag behind suspected totals during outbreaks because laboratory testing, contact tracing, and case verification take time. As a result, the real scale of transmission may initially appear smaller than it is.
Frontline workers involved in managing the dead are among the most vulnerable during Ebola outbreaks.
Ebola spreads through direct contact with infected blood or bodily fluids, including those from people who have died of the disease.
Corpses of Ebola victims are particularly dangerous because viral levels peak around the time of death and can remain high afterward. Handling bodies, washing them for funerals, or preparing them for burial can therefore expose workers to infectious fluids.
Research from previous outbreaks has shown that unsafe burial practices can drive transmission, with some studies linking a substantial share of new infections to funeral‑related contact with the deceased.
Because of these risks, trained burial teams must use full protective equipment and strict protocols to conduct what health authorities call “safe and dignified burials.”
As the outbreak spread across northeastern DRC and into Uganda, the World Health Organization declared the situation a Public Health Emergency of International Concern (PHEIC) on May 17, 2026.
A PHEIC designation signals that an outbreak poses a serious cross‑border public‑health risk and requires coordinated international action.
WHO has since worked with the DRC government and partners to scale up:
The organization has warned that the national risk within DRC is “very high,” though the risk globally remains lower.
Governments and public‑health agencies have also taken preventive steps to reduce the risk of international spread.
Officials say the risk of Ebola spreading to the United States remains low, though monitoring and preparedness measures are in place.
The deaths of the Red Cross volunteers highlight a common challenge in emerging outbreaks: diseases can circulate quietly before they are recognized.
In remote regions with limited diagnostic capacity, clusters of unexplained illness may initially be attributed to other diseases. Only after laboratory testing identifies the virus can authorities confirm an outbreak.
In this case, the March 27 exposure suggests that the Bundibugyo‑strain Ebola outbreak in eastern DRC likely began weeks before its official declaration, underscoring how crucial rapid detection, safe burial practices, and early surveillance are to containing deadly pathogens.
