(OPINION) : To combat Ebola, first build back trust in healthcare workers

The worst-ever outbreak of Ebola is spreading out of control in Guinea, Liberia, Sierra Leone, and now Nigeria, where almost 700 people have already died from the virus. Healthcare workers caring for Ebola patients have themselves fallen victim to the disease, including two American physicians. And, at its root, the size of this outbreak can be blamed on a lack of trust in healthcare workers.

Ebola is spread through direct contact with an infected person or their body fluids, which may include sweat, blood, urine, feces or vomit, making it difficult to contain outside of proper medical facilities.
There is no cure for Ebola, though supportive measures like intravenous fluids and antibiotics may be helpful in treating some of the complications of the disease. There is no vaccine to halt the spread of the virus. The only way to stop the transmission of Ebola is to identify and quarantine infected persons.

EU adopts toughest Russian sanctions yet, targets five Russian banks

Russia's President Vladimir Putin (C) chairs a government meeting at the Novo-Ogaryovo state residence outside Moscow, July 30, 2014.

The European Union has published a law that will curb arms sales to Russia and to cut off financing for five major Russian banks over Moscow's support for rebels in Ukraine.

Russia has denounced the measures, agreed by the 28 EU member states on Tuesday, as "destructive and short-sighted", while fighting has intensified in eastern Ukraine between Kiev forces and the pro-Russian separatists.

EU officials say the sanctions aim to inflict maximum pain on Russia and minimum pain on the EU. "We will for sure have an effect and a very substantial and concrete effect on Russia," one EU official said, speaking on condition of anonymity.

The toughest measures aim to prevent Russian banks from raising money on Western capital markets, while others limit defence sales and the export of hi-tech equipment for the oil sector.

Taxis, planes and viruses: How deadly Ebola can spread

Medical staff working with Medecins sans Frontieres (MSF) prepare to bring food to patients kept in an isolation area at the MSF Ebola treatment centre in Kailahun July 20, 2014.

For scientists tracking the deadly Ebola virus in West Africa, it's not about complex virology and genotyping, but about how contagious microbes - like humans - use planes, bikes and taxis to spread.

So far, authorities have taken no action to limit international travel in the region. The airlines association IATA said on Thursday that the World Health Organisation is not recommending any such restrictions or frontier closures.

The risk of the virus moving to other continents is low, disease specialists say. But tracing every person who may have had contact with an infected case is vital to getting on top of the outbreak within West Africa, and doing so often means teasing out seemingly routine information about victims' lives.

Under fire and out of cash, U.N. overwhelmed by Gaza crisis

Valerie Amos, United Nations Under-Secretary- General for Humanitarian Affairs and Emergency Relief Coordinator (seen on screen) briefs a U.N. Security Council meeting on the situation in the Middle East, at U.N. headquarters in New York, July 31, 2014.

The United Nations in Gaza is struggling to withstand a flood of almost a quarter of a million refugees into shelters that have repeatedly come under Israeli fire.

Out of cash, the United Nations Relief and Works Agency (UNRWA), the main U.N. body in the impoverished enclave of 1.8 million Palestinians, says it can barely handle the humanitarian crisis unleashed by more than three weeks of fighting between militants and Israel.

Asked to explain the scale of the civilian suffering to an Arab news station, an UNRWA spokesman simply burst into tears.

"There are times when tears speak more eloquently than words. Mine pale into insignificance compared with Gaza's," Chris Gunness said.

China says Islamist militants kill pro-Beijing imam in Xinjiang

Three suspected Islamist militants armed with knives and axes killed the imam of China's biggest mosque in the western region of Xinjiang on Wednesday, the authorities said, days after a knife-wielding gang attacked state buildings in the same region.

All three attackers, who were named by the government, had ethnic Uighur names and the imam, Juma Tayir, was a well-known pro-government Uighur who led prayers at the Id Kah Mosque in the old Silk Road city of Kashgar.

Xinjiang, home to the Muslim Uighur people, who speak a Turkic language, has for years been beset by violence, which the government blames on Islamist militants or separatists who it says want to establish an independent state called East Turkestan.

Exiled Uighur groups and human rights activists say the government's repressive policies in Xinjiang, including controls on Islam, have provoked unrest, a claim Beijing denies.
