In the comity of West African nations affected by the Ebola Virus Disease, Nigeria stood out for her prompt response and effective contact tracing mechanism. Less than seven weeks after the late index case, Mr. Patrick Sawyer, imported the EVD into the Nigeria from Liberia, there is yet to be any suspected or confirmed case.
Stakeholders have said that the United States, which recorded its own index case on September 20, when a Liberian, Mr. Thomas Eric Duncan, travelled from Liberia the US, can take away a lesson or two from Nigeria’s quick response.
Minister of Health, Professor Onyebuchi Chukwu, said there were more than 800 primary and secondary contacts between Sawyer and the ECOWAS official, Olu Koye-Ibukun, who took the virus from Lagos to Port Harcourt. In the end, health workers reportedly made 18,500 face-to-face visits, checking on the contacts for any symptoms of the disease.
On September 10, Chukwu had announced a total number of 19 confirmed EVD cases with seven deaths.
In the US, the wheel of contact tracing has been set in motion and the number of primary and secondary contacts of Duncan whittled down to 15.
A Reuters report on Sunday said, “While devastating reports continue to stream out of West Africa, where the deadly virus has overwhelmed already weak public health systems and left thousands of people dead, and anxiety grips the US over the first case of Ebola diagnosed in the country, one nation serves as an example of hope: Nigeria, which appears to have successfully contained Ebola.
“As concerns spread over US hospitals’ readiness, there are some lessons to be learned from Nigeria, where officials managed to get ahead of the fast-moving virus after it was brought into Africa’s most populous country by an Ebola-infected man, who had flown into Lagos. This week, the US Centres for Disease Control and Prevention reported that the outbreak could be coming to an end in Nigeria, with no new Ebola cases since August 31.
“As in the US case, Ebola arrived in Nigeria by passenger plane. But unlike Thomas Eric Duncan, who arrived in Dallas before he became symptomatic and was therefore not contagious during his flights from Liberia to Texas through Brussels and Dulles International Airport, Patrick Sawyer was already symptomatic when he landed in Lagos on July 20. At that point, Sawyer, Nigeria’s index case was contagious and dying.”
It continued, “It was a nightmare scenario with the potential to spiral out of control, given the bustling city of Lagos, Africa’s largest, is a major transport hub. As Sawyer was placed in isolation, public health officials had to track down every single person who had come into contact with him, from the flights he had boarded to the Lagos airport and the private hospital where he went after landing. And they had to do so quickly, making the process known as contact tracing a priority.
“In the whole system approach in beating the war on Ebola, contact tracing is the key public health activity that needs to be done,” said Gavin MacGregor-Skinner, who helped with the Ebola response in Nigeria with the Elizabeth R. Griffin Research Foundation. “The key is to find all the people that patient had direct close contact with.”
“From that single patient came a list of 281 people, MacGregor-Skinner said. Every one of those individuals had to provide health authorities twice-a-day updates about their well-being, often through methods like text-messaging. Anyone who didn’t feel well or failed to respond was checked on, either through a neighbourhood network or health workers.
Nigeria took a “whole community approach,” with everyone from military officials to church elders in the same room, discussing how to handle the response to the virus, MacGregor-Skinner said.
“Such an approach, and contact tracing in general, requires people to be open and forthright about their movements and their health, he said. Stigmatisation of patients, their families and contacts could only discourage that, so Nigerian officials sent a message to “really make them look like heroes,” MacGregor-Skinner said.
“This is the best thing people can do for Nigeria: They are going to protect and save Nigeria by being honest, by doing what they need to do, by reporting to the health commission,” he said. This made people feel like they were a part of something extremely important, he said, and also took into account real community needs. “You got real engagement and compliance from the contacts. They’re not running and hiding.”
Sawyer had come into contact with someone who ended up in Port Harcourt. That person went to a doctor who ended up dying from Ebola in August. Within a week, 70 people were being monitored. It ballooned to an additional 400 people in that one city.
Success stories of people coming through strict Ebola surveillance alive and healthy helped encourage more people to come forward, as they recognised that ending up in a contact tracer’s sights did not mean a death sentence.
The CDC also pointed to the robust public health response by Nigerian officials, who have had experience with massive public health crises in the past — namely polio in 2012 and large-scale lead poisoning in 2010.
When someone is on a contact list, that does not mean that person has to stay at home for the entire incubation period of 21 days from the last contact with someone who had Ebola. People on contact lists are not under quarantine or in isolation. They can still go to work and go on with their lives. But they should take their temperature twice a day for 21 days and check in with health workers.
The CDC recommends that people without symptoms but who have had direct contact with the bodily fluids of a person sick with Ebola be put under either conditional release, meaning that they self-monitor their health and temperature and check in daily, or controlled movement. People under controlled movement have to notify officials about any intended travel and shouldn’t use commercial planes or trains. Local public transport at use is approved on a case-by-case basis.
When symptoms do develop, that’s when the response kicks into high gear. People with Ebola are contagious only once they begin exhibiting symptoms, which include fever, severe headaches and vomiting.
While four people in Dallas are under government-ordered quarantine, which is not the norm. Those individuals “were non-compliant with the request to stay home. I don’t want to go too far beyond that,” Dallas County Judge Clay Lewis Jenkins said Thursday.
On Friday, the four people were moved to a private residence from the apartment where Duncan had been staying when he became symptomatic.
A law enforcement officer will remain with them to enforce the order, and none of the people are allowed to leave until October 19.
Duncan is the only person with an Ebola diagnosis in Dallas, and no one else is showing symptoms at the moment. But, as Nigeria knows, the work in Dallas has just begun. Click to signup for FREE news updates, latest information and hottest gists everyday

No need for self praise and accreditation. this only supports the fact that Nigeria Government is capable of achieving better result in Governance if only the want to. I keep saying what was achieved was because they know that if infected, there is no going abroad for medical care. Assuming the cure was only expensive thousands would have been dead by now
