Ebola May Remain Dormant in Survivors

Posted by on Sunday, May 1, 2016

Medical researchers think they may have found out why countries that become Ebola free suddenly has another outbreak. 

As it turns out the virus can persist in some survivors and be reintroduced to a once-uninfected region.

Usually as a person recovers from Ebola, the immune system clears out the virus and the person isn't contagious anymore. However the virus can lay dormant in the host.

Ebola is a viral hemorrhagic fever caused by ebolaviruses. Signs and symptoms typically start between two days and three weeks after contracting the virus with a fever, sore throat, muscular pain, and headaches. Then, vomiting, diarrhea and rash usually follow, along with decreased function of the liver and kidneys. At this time some people begin to bleed both internally and externally.

The disease has a high risk of death, killing between 25 and 90 percent of those infected, with an average of about 50 percent. This is often due to low blood pressure from fluid loss, and typically follows six to sixteen days after symptoms appear.
