The Sierra Leone death occurred earlier this week.
Ebola test centre spokesman Sidi Yahya Tunis told the BBC that the patient had died in the Tonkolili district. He had travelled there from Kambia, close to the border with Guinea.
The tests were conducted by British health experts. The BBC's Umaru Fofana in the capital Freetown said health officials were now urgently seeking those who had come into contact with the victim.
Close to 4,000 people have died of Ebola in Sierra Leone, and 11,000 people across the region, since December 2013.
Liberia was the last country to see the end of active transmission of Ebola. But it had been declared clear twice before, only for the infection to re-emerge.
A country is considered free of human-to-human transmission once two 21-day incubation periods have passed since the last known case tested negative for a second time.
The scientists conclude that the caffeine dose is not the whole story: perhaps our expectations also determine how alert we feel, or it could be that it’s the overall experience of the tastes, and smells, of our favourite drink that awakens our senses.
Verdict: Against logic, tea seems to provide just as powerful a wake-up call as coffee. It’s a draw.
Sleep quality
The biggest differences between coffee and tea may emerge once your head hits the pillow.
Most dentists seem to agree thatthan coffee’s – particularly if you use a mouthwash containing the common antiseptic chlorhexidine, which seems to attract and bind to the microscopic particles.
Verdict: If you want a perfect smile, coffee may be the lesser of two evils.
A balm for troubled souls…In England, it’s common to give “tea and sympathy” to a distressed friend – the idea being that a cup of Earl Grey is medicine for troubled minds. In fact, there is some evidence that tea can soothe your nerves: regular tea drinkers do tend to show a calmer physiological response to unsettling situations (such as public speaking), compared to people drinking herbal infusions. Overall, people who drink three cups a day appear to have a 37% lower risk of depression than those who do not drink tea.
There is some evidence that tea can soothe your nerves
Coffee doesn’t have the same reputation; indeed, some report that it makes them feel like their nerves are jangling. Yet there is some evidence that it too may protect against long-term mental health problems. A recent “meta-analysis” (summarising the results of studies involving more than 300,000 participants) found that each cup of coffee a day seems to reduce your risk of developing depression by around 8%. In contrast, other beverages (such as sweetened soft drinks) only increase your risk of developing mental health problems.
We need to take such results with a pinch of salt: despite the scientists’ best efforts, in this kind of large epidemiological study it’s hard to rule out other factors that may be behind the link – but it could be that both drinks offer a cocktail of nutrients that dampen down stress responses and boost mood in the long-term.
Verdict: Based on this limited evidence, it’s a draw.
…and a balm for bodiesSimilarly tantalising, though preliminary, epidemiological studies have suggested that both coffee and tea offer many other health-giving benefits. A few cups of either beverage a day appears to reduce your risk of diabetes, for instance. (The exact size of the benefit is still under discussion – estimates vary from around 5 to 40%.) Since even decaf coffee confers the same benefits, it seems likely that other nutrients may be oiling the metabolism so that it can still efficiently process blood glucose without becoming insensitive to insulin – the cause of diabetes.
A few cups of either beverage a day appears to reduce your risk of diabetes
Both drinks also seem to moderately protect the heart, although the evidence seems to be slightly stronger for coffee, while tea also appears to be slightly protective against developing a range of cancers – perhaps because of its antioxidants.
Verdict: Another draw – both drinks are a surprising, health-giving elixir.
Overall verdict: Much as we Brits would have liked tea to come out the clear victor, we have to admit there is little between the two drinks besides personal taste. Based solely on the fact that it allows you to get a better night’s sleep, we declare tea the winner – but why not share your own thoughts with us through social media?

Founder Jimmy Wales recently told the BBC that Wikipedia had a difficult birth.
"The first version of Wikipedia was called Nupedia," he said.
"It was very top-down, very structured. I beat my head against the wall for two years, I knew the system was too complicated, but I didn't want to fail."
Serious business
The Wikimedia Foundation, which runs Wikipedia, used the site's birthday to announce an endowment scheme to ensure a permanent source of funding for it and says it hopes to raise $100m (£69m) in the next 10 years.
The Foundation regularly asks for voluntary donations from readers and in 2014 raised $75.5m from 4.9m donors around the world, according to its own report.
On 3 December 2014 it received a record $29 (£20) per second, raising more than $2.5m (£1.7m) in one day.
Wikipedia sometimes hits the headlines when people make amusing edits to topical pages - but Jimmy Wales takes a dim view.
"If you wanna do something for your friends, click at it, make the funny change and just hit the preview button and just take a screenshot of that and you don't have to bother the rest of the world with your joke," he told BBC's Newsbeat in 2014.
Aleksi Aaltonen, assistant professor of information systems at Warwick Business School, said the site had come of age.
"The controversy and excitement that surrounded the service in the early days has passed," Mr Aaltonen said.
"As Wikipedia has grown older, it has become progressively more difficult for contributors to improve content. At the same time, Wikipedia's system of rules has become more burdensome.
"However, if Wikipedia can maintain its success, it will be remembered as a gift of an open internet that is now under attack from many directions."
Tsai Ing-wen has been elected Taiwan's first female president.
Ms Tsai, 59, leads the Democratic Progressive Party (DPP) that wants independence from China.
In her victory speech, she vowed to preserve the status quo in relations with China, adding Beijing must respect Taiwan's democracy and both sides must ensure there are no provocations.
China sees the island as a breakaway province - which it has threatened to take back by force if necessary.
In her speech, Ms Tsai hailed a "new era" in Taiwan and pledged to co-operate with other political parties on major issues.
The will of the Taiwanese people would be the basis for relations with China, Ms Tsai said.
"I also want to emphasise that both sides of the Taiwanese Strait have a responsibility to find mutually acceptable means of interaction that are based on dignity and reciprocity.
"We must ensure that no provocations or accidents take place," Ms Tsai said, warning that "any forms of suppression will harm the stability of cross-strait relations".
She thanked the US and Japan for their support and vowed Taiwan would contribute to peace and stability in the region.
Ms Tsai had a commanding lead in the vote count when Eric Chu of the ruling Kuomintang (KMT) admitted defeat.
Mr Chu congratulated Tsai Ing-wen and announced he was quitting as KMT head. Taiwan's Premier Mao Chi-kuo also resigned.
The election came just months after a historic meeting between the leaders of Taiwan and China.
However, the flagging economy as well as Taiwan's relationship with China both played a role in the voters' choice, correspondents say.
The KMT has been in power for most of the past 70 years and has overseen improved relations with Beijing - Ms Tsai's is only the second-ever victory for the DPP.
The first was by pro-independence advocate Chen Shui-bian; during his time as president between 2000 and 2008 tensions with China escalated.
Analysis: Cindy Sui, BBC News, Taipei
The election result marks a turning point in Taiwan's democracy and relationship with China.
The DPP win means the island is moving towards a political system in which voters prefer to transfer power from one party to another, ending decades of mostly KMT rule.
That could make relations with China uncertain, because unlike the KMT, the DPP favours Taiwan's independence and does not recognise the Republic of China (Taiwan's official name) and the People's Republic of China as part of "one China".
The KMT was the Communists' bitter enemy during the civil war. It fled to Taiwan after losing the civil war and its charter and leaders still favour eventual unification. It remains China's best hope - and perhaps only hope - of peacefully reunifying with Taiwan
Beijing has been closely watching the elections to gauge Taiwanese people's sentiments and what those sentiments will mean for its goal of reunifying with the last inhabited territory - following Hong Kong and Macau - that it feels was unfairly snatched from it by Japan as a colony in 1895, and then ruled separately by the KMT after the civil war.
Ms Tsai, a former scholar, has said she wants to "maintain [the] status quo" with China.
She became chairwoman of the DPP in 2008, after it saw a string of corruption scandals.
She lost a presidential bid in 2012 but has subsequently led the party to regional election victories. She has won increased support from the public partly because of widespread dissatisfaction over the KMT and President Ma Ying-jeou's handling of the economy and widening wealth gap.

Saturday's polls come after a historic meeting between President Ma and Chinese President Xi Jinping in Singapore in November for talks that were seen as largely symbolic - the first in more than 60 years.
Eric Chu, 54, is the mayor of New Taipei City and stepped up to become chairman of the party in October.
The KMT is at risk of losing its majority in the legislature for the first time in history.
The former accounting professor was seen as popular with young people in the party, but had been unable to change public opinion that is increasingly unhappy with the party's friendly stance towards China and the island's economic travails.
In 2014, hundreds of students occupied the parliament in the largest show of anti-Chinese sentiment on the island for years. Labelled the Sunflower Movement, protesters demanded more transparency in trade pacts negotiated with China.
Taiwan for all practical purposes been independent since the end of the Chinese civil war in 1949, when the defeated Nationalist government fled to the island as the Communists, under Mao Zedong, swept to power.
Rohit Sharma joined Tillakaratne Dilshan to become only the second cricketer to record two scores of 150 or more in losing causes, after his unbeaten 171 went in vain in the opening One-Day International (ODI) against Australia in Perth on Tuesday (January 12). We take a look at a list of big scores that unfortunately didn't end up on the victorious side.
Charles Coventry 194* vs Bangladesh, Bulawayo, 2009
Zimbabwe's No.3 equalled Saeed Anwar's then 12-year-old record for the highest individual score in ODIs, with a scintillating 156-ball effort but with the 37 being the next best score, Zimbabwe could only manage 312 in 50 overs. Tamim Iqbal then struck a brutal 154 as Bangladesh cantered to a win with more than two overs to spare. Coventry's record lasted all of six months as Sachin Tendulkar became the first batsman to score an ODI double-hundred in February 2010.
Matthew Hayden 181 vs New Zealand, Hamilton, 2007
Australia's burly opener was looking to nail down a spot in Australia's contingent for the 2007 World Cup and powered his way to a 166-ball 181, an innings that included as many as 10 sixes. Shaun Tait and Mitchell Johnson had the hosts wobbling at 41 for 4 in the chase before Craig McMillan and Brendon McCullum scripted an unlikeliest of turnarounds to chase down 346 with three balls to spare, sealing a 3-0 sweep of the Chappell-Hadlee series. The defeat notwithstanding, Hayden used the innings as a springboard for great success, ending as the World Cup's top-scorer.
Sachin Tendulkar 175 vs Australia, Hyderabad, 2009
Cameron White's lower-order blitz after Shaun Marsh's century took Australia to a daunting 350 in the fifth ODI, a total, which in 2009, was still one that the team batting first would win nine times out of 10. Then Sachin Tendulkar conjured up one of his gems. He scored half the team's total and by the time he was dismissed, on 175, attempting a cute paddle-sweep, India needed only 19 runs off 17 balls. Unfortunately, the follow-up batsmen could only manage 15 and Australia triumphed by three runs.
Rohit Sharma 171* vs Australia, Perth, 2016
Rohit Sharma began 2016 in sparkling fashion, easing himself to his ninth ODI century against a new-look Australian attack comprising Scott Boland, Joel Paris and Josh Hazlewood, before going into overdrive in the death overs. His unbeaten 171 helped the visitors post a daunting 309. No team had chased down more than 274 for a win at the WACA in Perth but that wasn't going to deter Steven Smith and George Bailey. The duo slammed tons in a 242-run third-wicket stand as Australia cantered to a win.
Robin Smith 167* vs Australia, Birmingham, 1993
England feared the worst when Australia asked them to bat on a cold, damp morning in Edgbaston. Within no time, Craig McDermott accounted for Graham Gooch and Alec Stewart. Robin Smith, batting at three, then conjured one of the best innings by an England batsman in ODI history. His 167, studded with 17 hits to the fence and three over it, remains the highest individual score in ODIs for England. But unfortunately, Mark Waugh's elegant 113 and Allan Border's unbeaten 86 helped Australia chase down 277 with relative ease.
Ricky Ponting 164 vs South Africa, Johannesburg, 2006
The greatest match of them all. When Ricky Ponting's 105-ball 164 propelled Australia to 434 in the bilateral series decider, all hopes appeared lost for South Africa. Faced against a near-impossible task, Herschelle Gibbs and Graeme Smith threw the kitchen sink at the Australian attack and pulled off a great heist. Gibbs outscored Ponting with a 111-ball 175 but shared the player of the match award with the Australian skipper. Hard to separate two innings of such an incredibly-high level.
Tillakaratne Dilshan 160* vs India, Hobart, 2012
Tillakaratne Dilshan and Kumar Sangakkara scored hundreds in a double-century stand as Sri Lanka flayed the Indian bowling attack in a crucial tri-series clash. Dilshan's unbeaten 160 took Sri Lanka to 320, a total India had to overhaul in 40 overs to keep their chances alive. Virat Kohli then enhanced his then-growing reputation as a chaser of totals - his 133 off 86 helped India reach the target under 37 overs.
Tillakaratne Dilshan 160 vs India, Rajkot, 2009
Another Tillakaratne Dilshan century ended in heartbreak as India clinched a nerve-wracking run-feast in Rajkot by three runs. A Virender Sehwag century and fifties from Sachin Tendulkar and MS Dhoni had propelled India to 414. Not one to give up without a fight, Dilshan stitched mammoth stands with Upul Tharanga (67) and Kumar Sangakkara (90) as Sri Lanka slowly but steadily, moved into ascendancy. When Dilshan got out in the 40th over, Sri Lanka needed just over 70 runs with six wickets in hand. Zaheer Khan and Ashish Nehra produced great spells at the death as India eked to victory.
When Australia travelled to India for a seven-match ODI series in late 2013, captain George Bailey was in imperious form. In the sixth game of the series at Jamtha, Nagpur, MS Dhoni, looking to stay alive in the series, decided to field first and watched helplessly as his bowlers were carted all around the field by his opposite number in a 113-ball essay that was laced with 13 fours and six sixes. Bailey's innings propelled Australia to 350 but the visitors weren't feeling all too comfortable. Virat Kohli, who had hunted down a 350-plus total earlier in the series, put on another masterclass and his unbeaten 66-ball 115 took India home with three balls to spare.
Kyle Coetzer 156 vs Bangladesh, Nelson, 2015
Kyle Coetzer gave Scotland hope of registering their first win in a World Cup when he scored a pleasing 156 off 134 balls against Bangladesh in Nelson during the 2015 World Cup. Coetzer's propensity to hit through the line over the infield on the off-side helped his team post 318. Unfortunately for Coetzer, Scotland's inexperienced bowling attack couldn't reign in the Bangladesh's big guns and fifties from Tamim Iqbal, Mahmudullah, Mushfiqur Rahim and Shakib-Al-Hasan helped the sub-continent nation overhaul the target with two overs to spare.
Hon. Mentions: Chris Gayle 152* vs South Africa in Johannesburg, 2014 and Rohit Sharma 150 vs South Africa, Kanpur, 2015

Ballon d'Or - world player of the year
Lionel Messiextended his record haul of world player of the year awards with his fifth after winning the treble - La Liga, the Copa del Rey and the Champions League - with Barcelona in 2014-15.
Portugal captain Ronaldo, 30, scored 57 goals in as many games in 2015 - including a record 16 in the Champions League - but that was not enough to win him Ballon d'Or number four.
Barcelona striker Neymar, 23, was the first Brazilian to finish in the top three since Kaka won the 2007 award.
He scored 45 goals in 62 games and is joint top scorer in this season's La Liga with 15, level with team-mate Luis Suarez.
"It's a very special moment for me to be back here on this stage, winning again another Ballon d'Or after seeing Cristiano win it," Messi said.
"It's incredible that it's my fifth, much more than anything I would have dreamed of as a kid."
