To many across the world today, the Ebola Virus Disease is a death sentence. But it is not.<\/p>\n

In recent times, pictures of survivors of the EVD from Liberia and Sierra Leone have graced the pages of the Nigerian media. Babies, teenagers and the elderly who have been through the glass pose for the camera in a well- earned victory dance.<\/p>\n

The EVD may have killed more than 1,500 people since its latest outbreak but the glistening faces of the survivors are proof that the disease is not a death sentence.<\/p>\n

This has been a key message from government officials since July 20 when the index case, Mr. Patrick Sawyer, arrived in Lagos from Monrovia, Liberia.<\/p>\n

Nigeria has recorded six deaths so far but there have also been a number of survivors.<\/p>\n

While addressing the press recently, Lagos State Governor, Mr. Babatunde Fashola, had advised Nigerians exhibiting symptoms consistent with the EVD to report early to the Infectious Disease Unit of the Mainland Hospital, Yaba, Lagos.<\/p>\n

According to him, the chances of surviving the disease are higher when the disease is tackled early with intensive supportive care.<\/p>\n

\u201cThis is a virus that will run a maximum of 21 days. What we must do is that people who are showing some signs of illness should come in very early so that we can continue to hydrate them, give electrolyte balance so that the nervous system does not go into shock and whenever it is necessary to provide antibiotics for patients and then the body can fight the virus which in any event last no longer than 21 days,\u2019\u2019 he said.<\/p>\n

The governor\u2019s views tallied with that of the Lagos State Chairman, Association of General and Private Medical Practitioners of Nigeria, Dr. Adeyeye Arigbabuwo. In an interview with our correspondent, Arigbabuwo affirmed that early presentation and treatment could be a turning point in the management of the disease.<\/p>\n

\u201cReporting early might change the picture of the progression of the disease. Then health workers have a good chance of preventing dehydration and correcting electrolyte imbalance, anemia and clotting issues. The disease should not be seen as a death sentence. What tends to make the patients bleed uncontrollably is disseminated intravascular coagulopathy.<\/p>\n

\u201cThis happens at the terminal phase and that means clotting factors in the body has been compromised. If all these are detected and corrected early, it is possible that the patient may survive. By the time you help to boost their immunity, that can change the outlook of the case,\u2019\u2019 he explained.<\/p>\n

Perhaps, some of the patients who died of EVD might have survived if they had reported early. That perhaps was the case with the matron of the First Consultant Medical Centre, who also died of the disease.<\/p>\n

The Lagos State Commissioner for Health, Dr. Jide Idris, admitted this much in an interview. \u201cApparently, she was at home for a long time without people knowing. As of the time the special and designated ambulance went to call her, it had deteriorated and that was why she did not stay too long in that place. This is the reason we keep saying anybody who has the symptoms should come out for proper therapy, \u2019\u2019 he added.<\/p>\n

Meanwhile, hope is in the horizon in the search of a cure for the EVD. In what scientists are calling a \u201cmonumental achievement,\u201d an experimental medication called ZMapp \u2014 given on a compassionate basis to a handful of Ebola victims in the current outbreak \u2014 cured 100 per cent of monkeys treated in a Canadian study, researchers announced Friday.<\/p>\n

ZMapp, made by Mapp Biopharmaceuticals of San Diego, is in the early stage of development and has never been formally tested in humans. In a study published Friday in the journal Nature, however, the drug allowed all 18 rhesus macaques infected with a lethal dose of Ebola to recover. The drug worked even when given five days after infection. The monkeys received three doses of ZMapp, administered three days apart, according to the study, which was conducted by the Public Health Agency of Canada.<\/p>\n

The three monkeys that did not receive ZMapp died within eight days of infection.<\/p>\n

In monkeys given ZMapp, however, the drug reversed severe symptoms, including severe bleeding, rashes and elevated liver enzymes, a sign of liver failure. Three weeks after infection, tests showed the surviving animals had no detectable Ebola virus in their blood.<\/p>\n

\u201cIt\u2019s fantastic news,\u201d says study co-author Gary Kobinger of the Public Health Agency of Canada. \u201cThis strongly supports\u201d the hope that ZMapp will work in humans, he says.<\/p>\n

The results are \u201ca monumental achievement,\u201d says Ebola researcher Thomas Geisbert of the University of Texas Medical Branch at Galveston, who was not involved in the current study but who wrote an accompanying editorial.<\/p>\n

Doctors used a different strain of Ebola virus in their study than the one that\u2019s currently circulating in West Africa. However, they tested ZMapp in test tubes against the current strain and found that it blocked infection.<\/p>\n

Although ZMapp hasn\u2019t been tested for safety in humans, its manufacturer shared a handful of doses with Ebola victims as a last-ditch effort to save their lives. Four of those patients \u2014 including two Americans and two Liberian health workers \u2014 survived after taking the drug. A fifth aid worker, who is now being treated in London, also has begun treatment with ZMapp. A Spanish priest and Liberian doctor given ZMapp died.<\/p>\n

Mapp Biopharmaceuticals has said that there are no more doses of ZMapp left. The drug, which includes three man-made antibodies to Ebola, takes months to manufacture. The antibodies are intended to allow the patients\u2019 immune system to respond to Ebola and fight off the infection.<\/p>\n

Given the limited experience with ZMapp in humans, it\u2019s not yet possible to know how ZMapp works in humans, Geisbert says.<\/p>\n

That\u2019s because ZMapp has been given to only a handful of patients, with no control group for comparison, he says.<\/p>\n

The Americans\u2019 cases are also unique. One of the American doctors who received ZMapp, Kent Brantly, also received a blood transfusion from a teenager who survived Ebola. So it\u2019s possible that the transfusion, not ZMapp, should get credit for saving him, Geisbert says. Receiving intensive care at Emory University Hospital in Atlanta \u2014 one of the best hospitals in the world \u2014 also could have helped the Americans survive.<\/p>\n

Geisbert notes that about half of Ebola patients survive without taking ZMapp.<\/p>\n

It\u2019s possible that the two Ebola patients who died after taking ZMapp got the drug too late, Geisbert says. There is a \u201cpoint of no return,\u201d he says, after which time nothing can save someone with Ebola, which causes tiny leaks in blood vessels, leading to massive internal and external bleeding, as well as organ failure. The immune system also can overreact in the late stages of Ebola, causing more harm than good.<\/p>\n

Three of the five species of Ebola virus are lethal to humans, Geisbert notes. A treatment that works against one species \u2014 or different strains of the same species \u2014 may not necessarily work against others.<\/p>\n

Ebola has infected more than 3,000 people in Guinea, Sierra Leone, Liberia, Nigeria and Senegal, killing half of them, according to the World Health Organization. Senegal reported its first case of Ebola on Friday.<\/p>\n

In a worrying development, researchers reported Thursday in Science that the Zaire strain of Ebola virus \u2014 the type now circulating in West Africa \u2014 appears to have mutated from its original form. The virus appears to be changing as it moves across Africa. Kobinger says he doesn\u2019t know how those mutations will affect the efficacy of ZMapp.<\/p>\n

Doctors at the National Institutes of Health plan to launch the first human trial of an Ebola vaccine next week at the institute\u2019s campus in Bethesda, Md., using healthy volunteers. The early study, using just 20 volunteers, will assess the experimental vaccine\u2019s safety and ability to activate the immune system to recognize the Ebola virus.<\/p>\n

Additional vaccine studies will be conducted in Bethesda, the United Kingdom and West Africa throughout the fall, NIH officials said Thursday. Early results from the first NIH trial are expected before the end of the year.<\/p>\n

Five experimental vaccines under development have been shown to completely protect monkeys against Ebola, Geisbert says. But only one of those vaccines is effective in a single injection \u2014 as opposed to multiple shots \u2014 an important practical advantage when trying to vaccinate hundreds or thousands of people in developing nations.<\/p>\n

Getting a usable treatment or vaccine could take many more months, however, officials caution. The best way to control the current outbreak is with traditional measures: diagnosing patients, isolating them, tracing their contacts and testing them, and extending the process out in circles, until all exposed patients have been isolated.<\/p>\n","protected":false},"excerpt":{"rendered":"
