People should always be concerned whenever there is an emerging infectious disease,
because we don't really know,
we don't have ways in which we can predict and project, and appropriately prepare for some of these.
Ian Lipkin is leading a team of scientists at Columbia University to investigate the virus,
which is in the same family as SARS and the common cold.
Symptoms include fever and severe respiratory problems.
Patients have also developed pneumonia and kidney failure.
Officials have found some clusters of cases where the disease has been transmitted between family members or in a health care setting.
Researchers are looking at whether it was initially passed from animals to humans.
Health officials don't know much about how the virus spreads,
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-to anywhere in the world right now,
but to just be aware of it.
Most of the cases and illnesses have been associated with the elderly and those with preexisting or severe underlying medical conditions.

Doctors are currently working on that.
In the cases that have been found in eight countries, all have been linked to the Middle East.

The company says it's going to update its guidelines for identifying hate speech,
and hold users more accountable for content considered cruel or insensitive.
Some Facebook users thanked the company.
Others said the changes don't go far enough.
Some users wondered if Facebook would 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.
