Ebola virus in humans may be here to stay; fatality rate is 71%
...In order to stop the epidemic, researchers say the rate of transmission would have to be cut in half. This would be equivalent to vaccinating 50% of the population.Several experimental vaccines are under development, and -- if they prove to be effective -- won't be available in large quantities for months.
Study authors made the following observations on the effects of the outbreak.
- The average age of a person infected with Ebola is 32, and 49.9% of patients are male, researchers said. The age group that has been most affected by the virus makes up 44% of the total population.
- The most common symptoms reported by patients included fever (87.1%), fatigue (76.4%), loss of appetite (64.5%), vomiting (67.6%), diarrhea (65.6%), headache (53.4%), and abdominal pain (44.3%).
- Although the disease is infamously known for causing bleeding, "specific hemorrhagic symptoms were rarely reported (in less than 1% to 5.7% of patients)," authors wrote. "Unexplained bleeding" however was reported in 18% of cases.
- People age 45 or older faced a significantly greater threat of death, as did those who suffered a number of the following symptoms: diarrhea, conjunctivitis, difficulty breathing or swallowing, confusion or disorientation and coma, unexplained bleeding, bleeding gums, bloody nose, bleeding at injection sites and bleeding from the vagina. http://www.latimes.com/science/sciencenow/la-sci-sn-ebola-may-be-endemic-in-people-20140922-story.html
