Battle vs Ebola gaining ground

0

The plague erupted deep in the forests of West Africa, sweeping through isolated villages and teeming cities before reaching across oceans to Europe and the United States.

Previous Ebola outbreaks have felled hundreds of people. But health officials report that this year’s epidemic has already sickened nearly 20,000 and killed about 7,700 of them, more than all other known occurrences combined.

As 2015 approaches, there is reason to hope that what at first was a plodding international response is finally catching up with the virus. In Liberia, the number of cases has been dropping rapidly. There are also signs that the disease may be slowing in Sierra Leone, which has overtaken Liberia as the country with the biggest caseload.

Dr. Thomas Frieden, director of the United States Centers for Disease Control and Prevention (CDC), told reporters on Tuesday that he was hopeful about stopping the epidemic but cautioned, “This is going to be a long, hard fight.”


In the hardest-hit countries, the effects of the outbreak could be felt for years. Health care systems have collapsed, schools closed, fields left untended and commerce curtailed.

The vast majority of the casualties have been in three West African nations: Liberia, Sierra Leone and Guinea. But the hysteria caused by one of the world’s most frightening diseases has outpaced the threat.

Although just four people fell ill in the United States, two of whom had been infected in Africa, it quickly became apparent that many hospitals weren’t as prepared for Ebola patients as the public had been led to believe. But a massive public health effort prevented further spread. Nigeria, Senegal and Spain also appear to have the virus contained, and Mali hasn’t reported a new case in weeks.

The Ebola epidemic began in a remote village in Guinea in December 2013, when a two-year old boy developed a mysterious illness and died. Other family members and a guest also fell ill, and soon the contagion was spreading to other communities.

Many health officials had never seen an Ebola outbreak and mistook the disease for more common ailments such as malaria or cholera. By the time the virus was identified in March, it had reached Guinea’s bustling capital, Conakry, and there were suspected cases in Liberia and Sierra Leone.

Africa not well equipped
The region’s ramshackle health facilities, devastated by warfare and chronic poverty, were not equipped for a major epidemic, and international health officials were slow to recognize the danger. The World Health Organization did not declare an international public health emergency until August. By then the virus was racing through the Liberian capital, Monrovia, a city of more than 1.3 million, and had reached Nigeria, Africa’s most-populous nation.

The following month, President Barack Obama announced that the US would send medical supplies and thousands of military personnel to West Africa to help fight a contagion that posed “a potential threat to global security.”

Britain, France, China and other countries also offered help. But it would take months to build essential treatment centers, establish labs and train personnel.

Frieden acknowledged this week that scaling up the response in Africa was “still a work in progress.”

“It is encouraging to see that when we get to a place where Ebola is spreading quickly, we can end that cluster within a month or two,” he said. “But the problem is, there are clusters all over, and new ones popping up all the time,” he added.

Many of the flare-ups are in isolated communities far from medical facilities or cellphone coverage and in some cases deeply hostile to the strangers who arrive in what look like moon suits to take their loved ones away.

Members of the Los Angeles-based International Medical Corps helped respond to one such outbreak in Grand Bassa County, in central Liberia.

At the time, there were no centers equipped to treat Ebola patients there, said Dr. Pranav Shetty, the group’s emergency health coordinator. Those suspected of having the virus would have to be taken to IMC units in two neighboring counties, a two-hour trek on foot through thick rain forest, over hills and across rickety bamboo bridges to reach a dirt road, then two more hours by ambulance.

It was impossible to carry patients that distance, so Doctors Without Borders took in tents to isolate those too sick to walk and prevent further spread of the virus.

“Unless we stamp out every last instance of this disease, it’s never going to go away,” Shetty said.

Although the tactics being used have stemmed smaller Ebola outbreaks, some experts are beginning to question whether this one has spread too far to be fully contained without a vaccine or cure.

Stephen Morse, a professor of epidemiology at Columbia University’s Mailman School of Public Health, said it has been encouraging to see new resources devoted to identifying better ways to fight Ebola.

The loss of life has been devastating in parts of West Africa, he said, but the survival rate has been higher in the US Only two of at least 10 patients treated in the US have died.

“Ebola for the first time is a manageable disease,” Morse said. “Once we have real treatments for it, it will become much different,” he added.

Heading into 2015, United Nations Secretary-General Ban Ki-moon is urging world leaders to learn lessons from the deadly epidemic, ones that go beyond strengthening public health systems.

“The international community needs better early warning and rapid response” mechanisms to stay ahead of the next disease outbreak, he told reporters in New York on Tuesday, “a test that is sure to come.”
