Health experts said this weekend could be key to finding out if more people in Dallas have contracted the Ebola virus.

According to the Centers for Disease Control, the current patient, Thomas Duncan, first started showing signs of the virus September 24, but wasn’t admitted to the hospital until the Sept. 28.

The incubation period for Ebola is typically 21 days, but most start showing symptoms earlier.

“Typically it’s about eight to ten days when people get sick,” said Dallas Morning News Medical Expert Dr. Seema Yasmin.

Ten people have been declared ‘high risk’ for contracting the virus.

They are currently under close observation by health officials

“The people who are being closely monitored are having their temperatures checked every day, sometimes twice a day. And they are in constant communication with public health officials about any fever or other signs or symptoms of Ebola,” Yasmin said.

If a person does begin to show signs of Ebola, they will most likely be put in isolation and then will undergo testing to see if it is, in fact, the virus.
