Experts advise authorities to take measures to forestall a possible outbreak of the Ebola virus disease in Nigeria, writes ARUKAINO UMUKORO
The news of the outbreak of Ebola fever
in some countries in West Africa, including several parts of Guinea,
Sierra Leone and Liberia has sent shock waves across the region, and
reverberated in other parts of the world.
West African countries like Senegal have since closed their land borders to check inter-border spread of the disease.
With death tolls rising in the affected
countries, Assistant Director-General of the World Health Organisation,
Keiji Fukuda, recently described the outbreak as ‘one of the most
challenging Ebola outbreaks’ the organisation has ever faced.
According to recent WHO figures, there
have been 157 suspected cases in Guinea, 101 of them fatal, while 67 of
the cases were confirmed in WHO laboratories.
The disease has no known cure or treatment yet.
“There is nothing available right now to
eliminate it,” said the President of the Nigerian Medical Association,
Dr. Osahon Enabulele, in an interview with SUNDAY PUNCH. He called on the Federal Government to seal the country’s borders so as to prevent the spread of Ebola virus in the country.
He said, “Anywhere you have movements of
people, from one location to the other, the likelihood is high. That
calls to attention the need for us to check our borders. More often than
not, when there are movements to some of these affected countries,
especially when there is a very defective, weak surveillance system at
the entry points—land, air and sea—people from endemic regions are given
access in the country.
“That leads to the possibility of having
it spread into those new locations, especially if there is contact with
those infected persons. So, if those surveillance mechanisms are not on
ground, if the level of suspicion is not high, then we could have an
infected person coming into the country.”
With over 170 million people, mostly in crowded urban areas, a possible outbreak in Nigeria could be disastrous.
In the same vein, veterinarian virologist
and President of the Nigerian Academy of Science, Prof. Oyewale Tomori,
noted that Nigeria was at risk of an outbreak of the Ebola virus,
considering that the affected countries are in West Africa.
Tomori said, “For it to suddenly appear
in Guinea and other places, it means that every country is at risk. As
long as there is travel between countries, we are liable to exposure to
whatever they carry.”
Enabulele stressed the need for people to know the symptoms of Ebola virus.
The symptoms include haemorrhagic fever,
weakness, muscle pain, vomiting, diarrhea and, in severe cases, organ
failure and unstoppable bleeding.
“It still boils down to having a very
high level of suspicion, especially among the citizens, to identify
anyone who may have an unrelenting fever, with some features like sore
throat, headache, body pains, deep coughing and breathing, vomiting and
diarrhea. Also, when a person is experiencing bleeding, especially from
the nose, it could be symptoms of viral haemorrhagic fevers,” Enabulele
explained.
Tomori urged hospitals in the country to
increase their level of suspicion and awareness about the virus, while
people with an unusually high fever should be quarantined, especially
now that it has spread to West Africa.
He said, “Anybody that has yellow fever
and has gone for treatment and there is no response, should quickly
report to the hospital. And if anybody comes into this country from that
part of West Africa, they need to be monitored for about two to three
weeks, if they develop fever, because this could be due to the
incubation period of the disease.”
According to WHO, the first outbreaks of
Ebola was recorded in 1976; in Nzara, Sudan, and in Yambuku, Democratic
Republic of Congo. The latter was in a village situated near the Ebola
River, from which the disease takes its name.
The incubation period of the Ebola virus varies, noted Enabulele.
“Averagely, it is about 12.5 days. But
the count rose from about 2 days to about 25 days, with an average
meantime of about 12.5 days. That substantially reflects the incubation
period. So, if one gets infected now, within two or 25 days, one can
come down with it,” he said.
A few days ago, while answering questions
from State House correspondents at the Presidential Villa, Abuja. the
Minister of Health, Prof. Onyebuchi Chukwu, denied earlier rumours of an
outbreak in the country, but admitted that the country was at risk,
considering the rate at which the virus had spread to other West African
countries.
Chukwu also said the National Centre for
Disease Control would raise awareness of the threat posed by the virus,
via television and radio jingles, as well as newspaper adverts.
He said, “Ebola has been moving eastward
towards Nigeria as well and we are already facing danger from the
Central African Republic, even with what is happening in Congo, people
are also migrating to Chad and Cameroon are also in our borders.
“So, Nigeria is in danger, but we have
recently said that in addition to the leaflets that we are producing for
Lassa and other fevers, we will now emphasise Ebola fever.”
Ebola virus disease currently has no vaccine.
However, Tomori was skeptical about the country’s ability to handle the emergency of a possible outbreak.
“We are not prepared for that. Our public
health system is not ready for such because it is weak. The laboratory
systems are poor and the awareness is not there,” he said.
Tomori’s view was corroborated by an
infectious disease specialist and professor of public health, New York
University, Dr. Joseph Onigbinde.
Onigbinde said this was a major reason
why the country’s health authorities needed to be on high alert and take
regular precautionary measures to avoid an outbreak.
He further said the Ebola virus would not have spread in these countries if the necessary precautionary measures were taken.
“I think the outbreak was not properly
managed at the start by the ministries of health in the affected
countries. They did not act on time. It took them some weeks before they
alerted the WHO. By that time, the virus was already spreading. Ebola
virus patients need to be quarantined, because they can easily transmit
the infection to other people and it spreads very fast,” he told our
correspondent.
WHO said the Ebola virus disease has a
fatality rate of up to 90 per cent. This is enough reason for the
country to take proactive measures to prevent any occurrence, noted
Enabulele.
He further said, “It is a very
devastating disease and it rapidly kills if not detected on time and no
supportive measures are made to ensure that the person is rehydrated and
some of those issues confronting the patient are taken care of. If
precautionary measures are not taken by the people and health workers,
who also attend to these health patients, it is a very devastating,
fatal ailment.
“For now, government has
promised to put in place modalities, heightening the level of
surveillance at the border points. So, let’s hope that, with the
declaration, there is no outbreak and we can maintain that; because if
we have this issue of Ebola virus, what we have seen of cholera may just
be child’s play.Source: Punch
