The Nasdaq Composite dropped 13,300 points, a 2.2% drop, to 6,908.80.

The tech sector has been one of the hardest hit by Ebola.
It reported a 3% drop in revenue for the third quarter.
The S&ams tech sector lost more then 5% of total revenue for a third straight year.

In a letter sent Monday to the countries, the U-N.
special rapporteur on the right to health said it was “extremely concerned” that some countries were not providing effective and timely access to basic services.
“While this is not a new issue, it has become an increasing concern, especially with the rise of Ebola in the recent months,” the U.-N.
The U.K.-based nonprofit said in a statement that it is concerned that the lack of transparency in the response to the virus “is creating unnecessary fear and panic.”
