With
quick and coordinated action by some of its top doctors, Nigeria,
Africa’s most populous country, appears to have contained its first
Ebola outbreak, the United States Centers for Disease Control and
Prevention said Tuesday.
As
the epidemic rages out of control in three nations only a few hundred
miles away, Nigeria is the only country to have beaten back an outbreak
with the potential to harm many victims in a city with vast, teeming
slums. Another pic after cut
“For
those who say it’s hopeless, this is an antidote — you can control
Ebola,” said Dr. Thomas R. Frieden, director of the C.D.C.
Although officials are pleased that success was achieved in a
country of 177 million
that is a major transport and business hub — and whose largest city,
Lagos, has 21 million people — the lessons here are not easily
applicable to the countries at the epicenter: Guinea, Liberia and Sierra
Leone. Public health officials in those countries remain overwhelmed by
the scale of the outbreak and are desperate for additional
international assistance.
Nigeria’s
outbreak grew from a single airport case, while in the three other
countries the disease smoldered for months in remote rain-forest
provinces and spread widely before a serious response was mounted.
Ebola, Dr. Frieden said, “won’t blow over — you have to make a rapid, intense effort.”
While
the danger in Nigeria is not over, the health minister, Dr. Onyebuchi
Chukwu, said in a telephone interview that his country was now better
prepared, with six laboratories able to make diagnoses and response
teams and isolation wards ready in every major state.
After
the first patient — a dying Liberian-American — flew into Lagos on July
20, Ebola spread to 20 other people there and in a smaller city, Port
Harcourt.
They have all now died or recovered, and the cure rate — 60 percent — was unusually high for an African outbreak.
Meanwhile,
local health workers paid 18,500 face-to-face visits to repeatedly take
the temperatures of nearly 900 people who had contact with them. The
last confirmed case was detected on Aug. 31, and virtually all contacts
have passed the 21-day incubation period without falling ill.
The success was in part the result of an emergency command center financed in 2012 by the
Bill & Melinda Gates Foundation to fight polio. As soon as the outbreak began, it was turned into the Ebola Emergency Operations Center.
Also,
the C.D.C. had 10 experts in Nigeria working on polio and H.I.V., who
had already trained 100 local doctors in epidemiology; 40 of them were
immediately reassigned to Ebola and oversaw the contact tracing.
The
chief of the command center, Dr. Faisal Shuaib, gave credit to a
coordinated effort by the Health Ministry, the C.D.C., the World Health
Organization, Unicef, Doctors Without Borders and the International
Committee for the Red Cross.
Also, he noted, Nigeria has significant advantages over poorer countries where the outbreak is out of control.
It has many more doctors per capita, some educated abroad at top medical schools.
It
has standing teams of medical investigators, with vehicles and
telephones, who normally trace outbreaks of other ills like cholera or
Lassa fever.
Lagos University Teaching Hospital was able to do Ebola tests in six hours.
The
hospitals where patients were isolated were equipped to do tests for
electrolytes and blood proteins, both of which must be kept in balance
as patients are fed orally or intravenously to replace fluids lost to
diarrhea and vomiting.
And air-conditioned hospitals let people wearing protective gear work longer without overheating.
Nigeria
also had some luck. Although the first patient, a businessman named
Patrick Sawyer, was vomiting on his flight in, none of the roughly 200
others on the plane fell ill. Others did after helping him into a taxi
to a hospital.
And
a patient in Port Harcourt went to her church and became violently ill
during a ceremony in which the congregation laid hands on her. But none
became infected.
Dr.
Sue Desmond-Hellmann, the Gates Foundation’s chief executive, said she
was “heartened to see this positive result of the efforts of so many in
Nigeria.”
On
July 17, Mr. Sawyer defied medical advice and left a hospital in
Monrovia, Liberia, where he was being held for observation after caring
for his sister, who died of Ebola, although it was unclear whether he
knew what she had.
Nigerian
news reports said he used Liberian government contacts for permission
to leave, flying to Lagos by way of Ghana and Togo. He planned to go to
an economic development conference there and then fly back to Coon
Rapids, Minn., for his children’s birthdays, according to
media interviews with his widow.
Taken
to a small private hospital after he collapsed, he denied any contact
with Ebola victims and was initially treated for malaria. He died on
July 25.
“That hospital had zero infection control,” Dr. Frieden said.
A
nurse who helped reinsert an IV line when Mr. Sawyer was delirious and
bleeding wore no gloves, had a cut on her hand and did not wash it, he
said. She later died.
After malaria treatment failed, Ebola was “high on the index of suspicion,” Dr. Shuaib said.
He learned about Mr. Sawyer’s diagnosis as he sat chatting in his office with a colleague.
“I thought: ‘Oh, my God, not Nigeria. Not Lagos.’ I knew the potential for it to spread in a densely populated place.”
Even
though the emergency center swung into action quickly and aggressive
contact tracing was possible because Nigeria’s Port Health Services
obtained records of Mr. Sawyer’s travel, there were still problems.
It took 14 days, Dr. Frieden said, for the first isolation ward to open in a former tuberculosis ward.
“Health workers initially wouldn’t go in,” he said. “They were afraid. We ultimately trained 1,800 staff.”
Wards
were reconfigured to add space between beds, put in washing stations
with chlorinated water and create rooms where doctors and nurses could
carefully don and remove protective gear. The worked in teams of two so
they could watch each other and prevent mistakes.
Also, according to
a C.D.C. study
released Tuesday in the Morbidity and Mortality Weekly
Report,
inaccurate news media reports before the government began offering
official information “created a nationwide scare.”
Sales of false cures, including “Blessed Salt,” shot up, and two Nigerians died of drinking large amounts of saltwater.
But
Dr. Shuaib emphasized that even terrified Nigerians did not deny the
virus’s existence or attack health workers, as happened in the other
countries. “No conspiracy theories entered the debate,” he said.
Nigeria’s
success shows how important preparation is, said Dr. Frieden, adding,
“Some countries that could well be the next Lagos still don’t have a
clue about how to deal with this.”
