Nigeria recorded its first case of Ebola in 2014 after a government official named Patrick Sawyer, who had been infected with the virus from Liberia, collapsed on arrival at the airport in country's biggest city, catching health authorities unaware.
Confirming the case in a chat with Reuters, the director of the main hospital in Democratic Republic of Congo's northwestern town of Bikoro said the health Centre received a new case.
"We are very concerned and planning for all scenarios, including the worst case scenario", Peter Salama, WHO's Deputy Director-General of Emergency Preparedness and Response, told a regular United Nations briefing in Geneva.
Congo's long experience of Ebola and its remote geography mean outbreaks are often localised and relatively easy to isolate.
The government of Congo declared a new outbreak of Ebola after at least two people were infected and possibly as many as 17 died from the disease in the country's northwest. However, the disease is not as gruesome as has sometimes been reported (body organs don't liquiefy), which makes it hard to figure out what's Ebola and what's not.
BJP moves EC, seeks countermanding of poll in Karnataka seat
How much do you know about the Karnataka elections? For the Congress government, women's safety is not a priority, he said. Congress, BJP and JDS have been campaigning aggressively in the state for the last few months to impress the voters.
This outbreak started back in December, about 20 miles from Bikoro, in Equateur province.
Ilunga told The Associated Press that the patient who died was a nurse. We don't know what causes these species jumps, which makes predicting Ebola outbreaks nearly impossible.
NAIJ.com notes that he said that World Health Organization had alerted the nine neighbouring countries but now regarded the risk of regional spread as "moderate".
The province of Equateur has an estimated population of 2.5 million people with 284 registered health facilities.
Normally a remote setting would reduce the chance of the disease spreading.
16 dead after thunderstorm hit several parts of UP
He said all the fix works of the damage caused by the storm must commence at the earliest along with the assessment of the damage. The death toll due to the thunderstorm which has been battering Western UP has reached 11, with over half a dozen people injured.
The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission, either through direct contact with bodily fluids such as blood or secretions or contact with materials that are contaminated with these liquids.
"My ministry established the National Health Emergencies Council to work expeditiously to prevent importation of any virus or disease".
An Ebola epidemic that hit West Africa in 2014 infected some 28,600 and killing more than 11,300 before World Health Organization declared the region Ebola-free two years later.
On Friday, Salama said he has spoken to DR Congo's health minister and hoped that he would soon have approval to use the vaccine, which was developed by Merck in 2016.
But the villages at the heart of this outbreak are close to the banks of the Congo River, a major artery for trade and transport upstream from the capital Kinshasa.
