How not to catch Ebola


Ebola virus
As the outbreak continues to spread, the fear of catching the disease is rising.
Experts are learning more about how to contain the virus that has infected around 7,500 people in West Africa.
The race is on to stop this deadly disease that kills more than half of those it infects.
Here's what is known.

DON'T TOUCH Ebola is spread by direct contact with contaminated body fluids. Blood, vomit and saliva can all carry and spread the deadly virus.

The relatives of sick patients and the healthcare workers who care for them are at highest risk of infection, but anyone who comes into close proximity potentially puts themselves at risk.
For that reason, contact should only be for essential medical care and always under the full protection of the right clothing.
The virus can't breach protective gear, such as gloves, a mask, goggles, a full body suit and tough rubber wellington boots, but too few have access to state-of-the-art kit.

How journalists protect themselves while reporting the outbreak
Those who do get to wear it should keep changing it every 40 minutes to be safe. Inside the suit it can get up to about 40C. Getting into the kit takes about five minutes. Taking it off again takes the wearer and a designated helper "buddy" about 15 minutes.
This is one of the most dangerous times for contamination and people are sprayed with chlorine as this happens.

  • Protective Ebola suit

  • Surgical cap

    ×
    The cap forms part of a protective hood covering the head and neck. It offers medical workers an added layer of protection, ensuring that they cannot touch any part of their face whilst in the treatment centre.

  • Goggles

    ×
    Goggles, or eye visors, are used to provide cover to the eyes, protecting them from splashes. The goggles are sprayed with an anti-fogging solution before being worn.

  • Medical mask

    ×
    Covers the mouth to protect from sprays of blood or body fluids from patients. When wearing a respirator, the medical worker must tear this outer mask to allow the respirator through.

  • Respirator

    ×
    A respirator is worn to protect the wearer from a patient's coughs. According to guidelines from the medical charity Medecins Sans Frontieres (MSF), the respirator should be put on second, right after donning the overalls.

  • Medical Scrubs

    ×
    A surgical scrub suit, durable hospital clothing that absorbs liquid and is easily cleaned, is worn as a baselayer underneath the overalls. It is normally tucked into rubber boots to ensure no skin is exposed.

  • Overalls

    ×
    The overalls are placed on top of the scrubs. These suits are similar to hazardous material (hazmat) suits worn in toxic environments. The team member supervising the process should check that the equipment is not damaged.

  • Double gloves

    ×
    A minimum two sets of gloves are required, covering the suit cuff. When putting on the gloves, care must be taken to ensure that no skin is exposed and that they are worn in such a way that any fluid on the sleeve will run off the suit and glove. Medical workers must change gloves between patients, performing thorough hand hygiene before donning a new pair. Heavy duty gloves are used whenever workers need to handle infectious waste.

  • Apron

    ×
    A waterproof apron is placed on top of the overalls as a final layer of protective clothing.

  • Boots

    ×
    Ebola health workers typically wear rubber boots, with the scrubs tucked into the footwear. If boots are unavailable, workers must wear closed, puncture and fluid-resistant shoes.

COVER YOUR EYES
personal protective equipment
If an infected droplet does get on to your skin, it can be washed away immediately with soap and water or an alcohol-based hand sanitiser.
The eyes are a different matter. A spray of droplets from a sneeze directly into the eye, for example, could let the virus in.
Similarly, the mucous membranes of the mouth and inside of the nose are vulnerable areas, as is broken skin.
line
LAUNDRY
worker in protective clothing
One of the most shocking symptoms of Ebola is bleeding. Patients can bleed from the eyes, ears, nose, mouth and rectum. Diarrhoea and vomit may also be tainted with blood.
A big infection risk is cleaning up. Any laundry or other clinical waste should be incinerated. Any medical equipment that needs to be kept should be decontaminated.
Without adequate sterilisation, virus transmission can continue and amplify.
Minute droplets on a surface that hasn't been adequately cleaned could, in theory, pose a risk. And it's unclear how long the virus could sit there and remain a threat. Flu viruses and other germs can live two hours or longer on hard environmental surfaces like tables, doorknobs, and desks.
The nurse who recently became infected while caring for two Ebola patients in Spain had twice gone into the room where one of the the patients was being treated - to be directly involved in his care and to disinfect the room after his death. Both times she was wearing protective clothing.
Soap and water or alcohol-based hand sanitisers readily disrupt the envelope of this single-stranded RNA virus, and decontamination with dilute bleach is effective and readily available even in remote settings.
line
CONDOMS
condoms
Generally, once someone recovers from Ebola and they have the all-clear, they can no longer spread the virus.
But according to the World Health Organization Ebola can be found in semen for seven weeks and some studies suggest it can be present for up to three months.
For this reason, doctors say that people who recover from Ebola should abstain from sex or use condoms for three months.

Sandhurst's sheikhs: Why do so many Gulf royals receive military training in the UK? A parade outside the building at Sandhurst Continue reading the main story In today's Magazine The death list that names 5,000 victims Is this woman an apostate? Voices from a WW1 prison camp The Swiss selfie scandal Generations of foreign royals - particularly from the Middle East - have learned to be military leaders at the UK's Sandhurst officer training academy. But is that still a good idea, asks Matthew Teller. Since 1812, the Royal Military Academy Sandhurst, on the Surrey/Berkshire border, has been where the British Army trains its officers. It has a gruelling 44-week course testing the physical and intellectual skills of officer cadets and imbuing them with the values of the British Army. Alongside would-be British officers, Sandhurst has a tradition of drawing cadets from overseas. Many of the elite families of the Middle East have sent their sons and daughters. Perhaps the most notable was King Hussein of Jordan. Continue reading the main story Find out more Matthew Teller presents Sandhurst and the Sheikhs, a Whistledown production for BBC Radio 4, on Wednesday 27 August 2014 at 11:00 BST It will be available on iPlayer shortly after broadcast Four reigning Arab monarchs are graduates of Sandhurst and its affiliated colleges - King Abdullah of Jordan, King Hamad of Bahrain, Sheikh Tamim, Emir of Qatar, and Sultan Qaboos of Oman. Past monarchs include Sheikh Saad, Emir of Kuwait, and Sheikh Hamad, Emir of Qatar. Sandhurst's links have continued from the time when Britain was the major colonial power in the Gulf. "One thing the British were excellent at was consolidating their rule through spectacle," says Habiba Hamid, former foreign policy strategist to the rulers of Dubai and Abu Dhabi. "Pomp, ceremony, displays of military might, shock and awe - they all originate from the British military relationship." Sheikh Hamad Bin Isa Al Khalifa, King Abdullah, Sultan Qaboos Sandhurst alumni: King Hamad of Bahrain, King Abdullah of Jordan and Sultan Qaboos of Oman It's a place where future leaders get to know each other, says Michael Stephens, deputy director of the Royal United Services Institute, Qatar. And Sandhurst gives the UK influence in the Gulf. "The [UK] gets the kind of attention from Gulf policy elites that countries of our size, like France and others, don't get. It gives us the ability to punch above our weight. "You have people who've spent time in Britain, they have… connections to their mates, their teachers. Familiarity in politics is very beneficial in the Gulf context." "For British people who are drifting around the world, as I did as a soldier," says Brigadier Peter Sincock, former defence attache to Saudi Arabia, "you find people who were at Sandhurst and you have an immediate rapport. I think that's very helpful, for example, in the field of military sales." The Emir of Dubai Mohammad bin Rashid Al Maktoum with his son after his Passing Out Parade at Sandhurst in 2006 Sheikh Mohammad bin Rashid Al Maktoum, Emir of Dubai, with his son in uniform at Sandhurst in 2006 Her Majesty The Queen's Representative His Highness Sheikh Hamad bin Khalifa Al-Thani, The Emir of Qatar inspects soldiers during the 144th Sovereign's Parade held at The Royal Military Academy Sandhurst on April 8, 2004 in Camberley, England. Some 470 Officer cadets took part of which 219 were commissioned into the British Army Hamad bin Khalifa Al-Thani, the Emir of Qatar until 2013, inspects soldiers at Sandhurst in 2004 Emotion doesn't always deliver. In 2013, despite the personal intervention of David Cameron, the UAE decided against buying the UK's Typhoon fighter jets. But elsewhere fellow feeling is paying dividends. "The Gulf monarchies have become important sources of capital," says Jane Kinninmont, deputy head of the Middle East/North Africa programme at the foreign affairs think tank Chatham House. "So you see the tallest building in London being financed by the Qataris, you see UK infrastructure and oilfield development being financed by the UAE. There's a desire - it can even seem like a desperation - to keep them onside for trade reasons." British policy in the Gulf is primarily "mercantile", says Dr Kristian Coates Ulrichsen, of the Baker Institute in Houston, Texas. Concerns over human rights and reform are secondary. The Shard at dusk The Shard was funded by Qatari investors In 2012 Sandhurst accepted a £15m donation from the UAE for a new accommodation block, named the Zayed Building after that country's founding ruler. In March 2013, Sandhurst's Mons Hall - a sports centre - was reopened as the King Hamad Hall, following a £3m donation from the monarch of Bahrain, who was educated at one of Sandhurst's affiliated colleges. The renaming proved controversial, partly because of the perceived slight towards the 1,600 British casualties at the Battle of Mons in August 1914 - and partly because of how Hamad and his government have dealt with political protest in Bahrain over the last three years. A critic might note that the third term of Sandhurst's Officer Commissioning Course covers counter-insurgency techniques and ways to manage public disorder. Since tension between Bahrain's majority Shia population and minority Sunni ruling elite boiled over in 2011, more than 80 civilians have died at the hands of the security forces, according to opposition estimates, though the government disputes the figures. Thirteen police officers have also lost their lives in the clashes. "The king has always felt that Sandhurst was a great place," says Sincock, chairman of the Bahrain Society, which promotes friendship between the UK and Bahrain. "Something like 20 of his immediate family have been there as cadets. He didn't really understand why there was such an outcry." David Cameron and King Hamad David Cameron meeting King Hamad in 2012... A protester is held back by police ... while protesters nearby opposed the Bahrain ruler's human rights record Crispin Black, a Sandhurst graduate and former instructor, says the academy should not have taken the money. "Everywhere you look there's a memorial to something, a building or a plaque that serves as a touchstone that takes you right to the heart of British military history. Calling this hall 'King Hamad Hall' ain't gonna do that." Sandhurst gave a written response to the criticism. "All donations to Sandhurst are in compliance with the UK's domestic and international legal obligations and our values as a nation. Over the years donations like this have saved the UK taxpayer a considerable amount of money." But what happens when Sandhurst's friends become enemies? In 2001, then-prime minister Tony Blair visited Damascus, marking a warming of relations between the UK and Syria. Shortly after, in 2003, Sandhurst was training officers from the Syrian armed forces. Now, of course, Syria is an international pariah. Journalist Michael Cockerell has written about Libyan dictator Colonel Gaddafi's time at the Army School of Education in Beaconsfield in 1966: "Three years [later], Gaddafi followed a tradition of foreign officers trained by the British Army. He made use of his newfound knowledge to seize political power in his own country." Ahmed Ali Sandhurst-trained Ahmed Ali was a key player in the Egyptian military's removal of Islamist President Mohammed Morsi That tradition persists. In the 1990s Egyptian colonel Ahmed Ali attended Sandhurst. In 2013 he was one of the key figures in the Egyptian military's removal of Islamist President Mohammed Morsi, now rewarded by a post in President Sisi's inner circle of advisers. In the late 1990s there were moves by the British government under Tony Blair to end Sandhurst's training of overseas cadets. Major-General Arthur Denaro, Middle East adviser to the defence secretary and commandant at Sandhurst in the late 1990s, describes the idea as part of the "ethical foreign policy" advocated by the late Robin Cook, then-foreign secretary. Tony Blair and Robin Cook Tony Blair and Robin Cook at one point planned to end Sandhurst's training of overseas cadets The funeral of King Hussein in 1999 appears to have scuppered the plan. "Coming to that funeral were the heads of state of almost every country in the world - and our prime minister was there, Tony Blair," says Major-General Denaro. "He happened to see me talking to heads of state - the Sultan of Brunei, the Sultan of Oman, the Bahrainis, the Saudis - and he said 'How do you know all these guys?' The answer was because they went to Sandhurst." Today, Sandhurst has reportedly trained more officer cadets from the UAE than from any other country bar the UK. The May 2014 intake included 72 overseas cadets, around 40% of whom were from the Middle East. "In the future," says Maryam al-Khawaja, acting president of the Bahrain Centre for Human Rights, "people will look back at how much Britain messed up in the [Middle East] because they wanted to sell more Typhoon jets to Bahrain, rather than stand behind the values of human rights and democracy." "It's one thing saying we're inculcating benign values, but that's not happening," says Habiba Hamid. Sandhurst is "a relic of the colonial past. They're not [teaching] the civic values we ought to find in democratically elected leaders." line Who else went to Sandhurst? Princes William and Harry, Winston Churchill, Ian Fleming, Katie Hopkins, Antony Beevor, James Blunt, Josh Lewsey, Devon Harris (From left to right) Princes William and Harry Sir Winston Churchill Ian Fleming, creator of James Bond (but did not complete training) Katie Hopkins, reality TV star Antony Beevor, historian James Blunt, singer-songwriter Josh Lewsey, World Cup-winning England rugby player Devon Harris, member of Jamaica's first bobsleigh team line Sandhurst says that "building international relations through military exchanges and education is a key pillar of the UK's international engagement strategy". Sandhurst may be marvellous for the UK, a country where the army is subservient to government, but it is also delivering militarily-trained officers to Middle Eastern monarchies where, often, armies seem to exist to defend not the nation but the ruling family.
