Firt up. Three suspicious letters. One was sent to President Obama; the other two were sent to New York Mayor Michael Bloomberg and to an organization he founded. Initial tests on those two letters indicated they were tainted¹ with poison, called ricin. As of yesterday afternoon, officials hadn't said whether ricin was founded on the letter addressed to the White House, although they did day the letter was similar.

Ricin, seriously dangerous, even a tiny amout of it can kill someone in 2 days or less by shutting respiratory or circulatory systems. There is no known antidote² for it.

You might remember a month so ago, letters tainted with ricin were sent to the president and another officials. Authorities don't think there is connection between that and the new letter sent to President Obama.

Health officials say that region seems to be the starting point for a dangerous new virus, in order to fight the diseases scientists need information. Right now, they don't know where the virus started, they don't know how it spreaded. Mary Snow explains what is known about what is becoming a medical mystery.

Hollywood movies like Contagion³ are sobering reminders⁴ of the real threat of the deadly viruses.

--So we have virus that no treatment protocol⁵ and no vaccine⁶ at this time.

Reports of a new strain of corona⁷ virus overseas is no where near the movie version of outbreak. So far there were reported cases in the United States. It's named the Middle East Respiratory Syndrome⁸ Corona Virus. The World Health Organization is calling it a threat to the world.

--This is a grave concern to us here international WHO. Because there are so many unknowns around the virus which so far has killed 55 person of the confrimed cases.

Cases have been linked from the Middle East to the UK, Germany, France and Tunisia, so far 27 have died with the largest number in Saudi Arabia.

--Should people be concerned about this?

--People should always be concerned whenever there is an emergent infectious disease. Because we don't really know, we don't have ways in which we can predict and project, and properly prepare for some like this.

Ian Lipkin is leading a team of scients in Columbia University to investigate the virus which is in the same family of SARS and common cold, symptoms include fever and severe respiratory problems. Patients have also developped pneumonia⁹ and kidney failure.

Officials have found some clusters of cases with the disease has been transmitted between family members or in a healthcare setting. Researchers are looking at whether it was initially¹⁰ passed from animals to humans.

Health officials don't know much about how the virus spread. But at this point, travel warnings have not been issued.

--I don't think we should be concerned in terms of travel to the Middle East or to anywhere in the world right now, but just be aware of it. Most cases and illnesses were associated with the elderly and those with preexisting or severe underlying¹¹ medical conditions.

The World Health Organization is so concerned about this virus, because there is no known treatment and no way to make vaccine, not just yet. Doctors are currently working on that. In the cases that have been found in a country's all have been linked to the Middle East. Mary Snow, CNN, New York.

All you know these terms of agreement when you sign up for a website. Facebook has one that says you will not post context that is hate speech. Now the company is increasing its efforts to get rid of hate speech. It's a response to a campaign by women's group. The campaign targeted a Facebook pages that celebrated¹² a joke about violence against women. Facebook says it tries to find a balance between cracking down on hateful content and allowing for freedom of expression. But a new company post says in recent days it become clear that our systems to identify and remove hate speech have failed to work as effectively as we would like.

The company says it's going to update its guidelines for identifying hate speech and hold user more accountable for content consider cruel or insensitive.

Some Facebook users thanked the company; other said the change don't go far enough; some users wondered if Facebook woul keep up the increased efforts long term. What about freedom of speech? That's not really an issue here. Facebook is a private site, you might be able to post what you want, but Facebook is free to take it down and cancel your account.
