(CNN) -

More than 1,200 people have died as the deadliest ever outbreak of Ebola takes hold in West Africa, but despite information campaigns, fear is spreading even more quickly than the virus itself.

This week some Ebola patients in Liberia ran away when the health care facility they were being treated at was attacked by rioters frightened of the disease.

As medical staff and authorities battle to contain Ebola, are rumors and superstition making the situation more difficult?

Are myths making the Ebola outbreak worse?

"Absolutely," says CNN's Nima Elbagir, adding that the Liberia clinic attack is just one sign of spiraling fear about the disease, which means that those who become sick are terrified of seeking help.

The World Health Organization says the "scale, duration, and lethality of the Ebola outbreak have generated a high level of public anxiety" over the virus.

"People worry that they will be ostracized by their community if they admit that they are ill or that their loved ones appear to have died of Ebola, so they delay reporting the symptoms, and we've heard anecdotes about secret burials," Elbagir explains.

A lack of understanding about what causes Ebola and how it is passed on means the region is fertile ground for speculation and mistaken beliefs.

And according to the WHO, the already difficult conditions are also being made tougher by public misunderstanding caused by "rumors on social media claiming that certain products or practices can prevent or cure Ebola virus disease."

What sort of myths and rumors are involved?

The WHO reports that at least two people died in Nigeria as a result of drinking salt water, after stories circulated that doing so would protect against Ebola.

Other supposed "cures" for the disease include raw onions, coffee, condensed milk and holy water.

While there are high hopes for experimental medicines and vaccines, the WHO points out there is, as yet, no known cure. "Decades of scientific research have failed to find a curative or preventive agent of proven safety and effectiveness in humans," it says.

The organization has warned against paying heed to any old wives' tales about potential treatments:

"A lot of rumours on social media claiming certain products, practices can prevent or cure #Ebola. They are false, their use can be dangerous," it tweeted Tuesday.

Earlier this year, at the start of the outbreak, a team from Medecins Sans Frontieres had to stop working in one isolation ward in Guinea because local residents mistakenly believed they had brought the virus with them.

It's a common misconception which makes the work of medical staff harder than it already is, MSF's Dr. Marc Forget told CNN: "(When we decontaminate houses) they think we are spreading the disease, so some villages just shut down their access, they put trees on the roads."

He says groups from MSF, the Red Cross and the Ministry of Health have also been pelted with rocks as they try to reach Ebola-hit areas.

Elbagir says the region's recent history of bloody civil war also feeds the rumor mill, with some claiming that the fact the army has been deployed to stop people dumping bodies in the streets is a sign the government is deliberately infecting people in order to have an excuse to enforce martial law.

Why are they proving so hard to dispel?

According to Nima Elbagir, widespread suspicion of authority, coupled with a lack of basic infrastructure mean that educating people about how to avoid infection is extremely difficult.

"These are very remote places in countries still bearing the scars of war (in Liberia and Sierra Leone) -- people are already traumatized and there is a lot of distrust to be overcome: when the government says something, people don't necessarily believe it," she says.

"There aren't enough doctors and health care workers -- people just aren't used to seeing them in their communities, and so they aren't the figures of authority that they are elsewhere."

Elbagir said the practice of quarantining whole areas "almost like the plague villages of the Middle Ages," had also led to anger and mistrust as entire communities were cut off from vital supplies. "People say 'We're going to die of hunger before we die of Ebola!'" she said.

The World Food Programme says it is working to "provide food assistance to around one million people living in restricted access areas in the three affected countries" in an attempt to "stabilize affected communities by limiting unnecessary movement and enabling them to cope with lost livelihoods."
