Nigeria
health officials waited to screen passengers at the arrival hall of Murtala
Muhammed International Airport in Lagos, Nigeria, on Monday. Nigerian
authorities on Monday confirmed a second case of Ebola in Africa's most
populous country.
ABUJA,
Nigeria — The doctor who treated a man who flew to Nigeria and died of Ebola
now has contracted the disease, authorities said Monday, presenting a dire
challenge to Africa’s most populous nation as the regional toll for the
outbreak grew to 887 dead. continue...
As
Nigerian health authorities rushed to quarantine others who had been exposed to
the doctor, a special plane landed in Liberia to evacuate the second American
missionary who fell ill with Ebola. Nancy Writebol, 59, is expected to arrive
in Atlanta on Tuesday, where she will be treated at a special isolation ward.
The
second confirmed case in Nigeria is a doctor who treated Patrick Sawyer, the
Liberian-American man who died July 25 days after arriving in Nigeria from
Liberia, said Nigerian Health Minister Onyebuchi Chukwu.
Three
others who also treated Sawyer now show symptoms of Ebola and their test
results are pending, he said. Authorities are trying to trace and quarantine
others in Lagos, sub-Saharan Africa’s largest city of 21 million people.
“This
cluster of cases in Lagos, Nigeria is very concerning,” said Dr. Tom Frieden,
director of the U.S. Centers for Disease Controls and Prevention, which is
dispatching 50 experienced disease control specialists to West Africa.
“It
shows what happens if meticulous infection control, contact tracing, and proper
isolation of patients with suspected Ebola is not done. Stopping the spread in
Lagos will be difficult but it can be done,” he said.
The
World Health Organization announced Monday that the death toll has increased
from 729 to 887 deaths in Guinea, Sierra Leone, Liberia and Nigeria.
Cases
in Liberia jumped from 156 to 255, WHO said, as the government ordered that all
Ebola victims must now be cremated because of rising opposition to burials in
neighborhoods around the capital. Over the weekend, police were called in amid
a standoff over whether health authorities could bury nearly two dozen victims
in a neighborhood on the outskirts of the capital, Monrovia.
Sierra
Leone marked a national stay-at-home day Monday in an effort to halt the
disease’s spread. A documentary film of the first outbreak of the Ebola disease
in Congo was being shown intermittently throughout the day by the national
broadcaster.
The
emergence of a second case in Nigeria raises serious concerns about the infection
control practices there, and also raises the specter that more cases could
emerge. It can take up to 21 days after exposure to the virus for symptoms to
appear. They include fever, sore throat, muscle pains and headaches. Often
nausea, vomiting and diarrhea follow, along with severe internal and external
bleeding in advanced stages of the disease.
“This
fits exactly with the pattern that we’ve seen in the past. Either someone gets
sick and infects their relatives, or goes to a hospital and health workers get
sick,” said Gregory Hartl, World Health Organization spokesman in Geneva. “It’s
extremely unfortunate but it’s not unexpected. This was a sick man getting off
a plane and unfortunately no one knew he had Ebola.”
Doctors
and other health workers on the front lines of the Ebola crisis have been among
the most vulnerable to infection as they are in direct physical contact with
patients. The disease is not airborne, and only transmitted through contact
with bodily fluids such as saliva, blood, vomit, sweat or feces.
Sawyer,
who was traveling to Nigeria on business, became ill while aboard a flight and
Nigerian authorities immediately took him into isolation upon arrival in Lagos.
They did not quarantine his fellow passengers, and have insisted that the risk
of additional cases was minimal.
Nigerian
authorities said a total of 70 people are under surveillance and that they
hoped to have eight people in quarantine by the end of Monday in an isolation
ward in Lagos.
Tracking
down all the people who came into contact with Sawyer and his caregivers could
prove difficult at this late stage, said Ben Neuman, a virologist and Ebola
expert at Britain’s University of
Reading.
“Contact
tracing is essential but it’s very hard to get enough people to do that,” he
said. “For the average case, you want to look back and catch the 20 to 30
people they had closest contact with and that takes a lot of effort and legwork
… The most important thing now is to do the contact tracing and quarantine any
contacts who may be symptomatic.”
