Underlining the immense risks taken by those working in West Africa to
understand and combat the worsening Ebola outbreak, five co-authors of
an important new Ebola study were killed by the virus before their
research was published.
The study, published Thursday in the
journal Science, found that the virus has mutated during the outbreak —
something that could hinder diagnosis and treatment of the disease.
The
five deceased co-authors, who were from Sierra Leone’s Kenema
Government Hospital Lassa fever facility, worked with the study’s lead
researchers at Harvard University to examine the deadliest Ebola
outbreak in history. In all, the research involved more than 50
co-authors.
It’s an extraordinary study, and it came with an
extraordinary toll. Pardi Sabeti, whose Harvard lab oversaw the genetic
sequencing at the center of the research, told The Post’s Brady Dennis
that the the experience of working on the international study was “one
of the most rewarding and devastating experiences of my life,” with the
thrill of conducting the collaborative research tempered by the sadness
of losing numerous colleagues who were working on the front lines.
The
study demonstrates just how effective an international research effort
can be in the middle of a global health crisis. Researchers sequenced
the virus genomes from 78 patients in the current outbreak, starting
with its early days in the spring.
Among other things, the
international team of researchers managed to trace the outbreak in
Sierra Leone to a single funeral in the country. Researchers discovered
that a pregnant Kenema Government Hospital Ebola patient had, along with
about a dozen other women who were also infected, attended the funeral
of a traditional healer who was treating Ebola victims on the Sierra
Leone-Guinea border.
On the same day the findings were published,
Science wrote a separate piece about the five researchers who died
while working on the study.
Mbalu Fonnie, an experienced nurse at
the Kenema Government Hospital, was among the five victims. Her
specialty? Managing advanced Lassa fever infections — a disease with
symptoms similar to Ebola — in pregnant women. Fonnie was caring for one
of her co-workers, who was pregnant and infected with Ebola, when she
contracted the disease herself. According to study co-author Robert
Garry, Fonnie was the “matron of nursing” at the Sierra Leone hospital.
Alex
Moigboi, Fonnie’s fellow nurse, who contracted Ebola while treating the
same pregnant colleague. He had more than 10 years of experience
working with Lassa fever patients.
Alice Kovoma was also infected
while helping Fonnie and Moigboi treat their colleague. Garry told
Science that Kovoma was “a wonderful person … very dedicated and
professional with a devotion to the patients and her teammates.” She was
a nurse for six years in the Lassa fever ward.
Mohamed Fullah
worked as a lab technician on the study. He taught at Eastern
Polytechnic College in Sierra Leone, and also worked in the Lassa fever
facility. His colleagues believe that Fullah contracted the disease from
a family member — several relatives had died of the virus in the
current outbreak, which has killed at least 1,552 people, according to
the World Health Organization.
Sheik Umar Khan was the director
of the Ministry of Health and Sanitation’s Lassa fever program and was
directly involved in Sierra Leone’s national response to the Ebola
outbreak. He was a well-respected expert on both Lassa fever and Ebola.
At the time of his death, in late July, Khan was hailed as a national
hero. He treated more than 100 patients in the outbreak before he
contracted the disease himself.
In a June interview with Reuters,
Khan spoke of the dangers health-care workers face while working with
Ebola: “I am afraid for my life, I must say, because I cherish my life.
Health workers are prone to the disease because we are the first port of
call for somebody who is sickened by disease. Even with the full
protective clothing you put on, you are at risk.
Khan was treated
at a Doctors Without Borders facility after contracting the virus. His
death prompted an international discussion after Doctors Without Borders
was forced to defend its decision against giving Khan an experimental
drug to treat the disease.
On the same day the study was
published, the WHO warned that the current outbreak could infect more
than 20,000 people before it’s over. On Friday, officials in Senegal
announced that the country had its first confirmed case of Ebola.
Five
countries — Sierra Leone, Liberia, Guinea, Nigeria and now Senegal —
have confirmed Ebola infections within their borders. (Ebola cases have
been reported in Congo, too, but health officials there have said it’s a
different strain of the deadly virus, not connected to the outbreak in
West Africa.)
There have been 3,069 Ebola infections recorded by
the WHO, and more than half of those infected have died, according to
the WHO.
