Via Reuters, alarming news: Exclusive: WHO, Congo eye tighter rules for Ebola care over immunity concerns. Excerpt:
The World Health Organization and Congolese authorities are proposing changes to how some Ebola patients are cared for, new guidelines show, after a patient’s death challenged the accepted medical theory that survivors are immune to reinfection.
There are many unanswered questions surrounding the circumstances of the woman’s death in Democratic Republic of Congo, which has not previously been reported.
But it has raised concerns because the woman, whose name has not been released for confidentiality reasons, was thought to have had immunity after surviving infection, but fell ill again with Ebola and died.
“That was a big red flag event for all of us,” said Janet Diaz, who leads the World Health Organization’s clinical management team for the epidemic in Congo.
Congo’s Ebola outbreak has infected over 3,000 people and killed more than 2,000 since August last year. It is the second-worst outbreak after one in West Africa between 2013 and 2016 that killed more than 11,000 people.
The woman was working as a caregiver in the high-risk “red zone” of a treatment center in Beni, eastern Congo, according to health officials familiar with her case.
She was one of dozens of people assigned to care for Ebola patients because it was assumed they would not get sick as Ebola survivors, although some researchers have considered reinfection to be at least a theoretical possibility.
Their presumed immunity allowed for closer contact with sufferers, many of them children.
Alima, the medical charity that co-ran the Beni center where she worked, said she tested positive for Ebola and died in July before she could be readmitted for treatment.
But it is not yet known whether the woman received a false positive result the first time she was tested, experienced a relapse or was reinfected, health officials say.
