zed, but only rinsed before re-insertion into multi-use vials of medicine. If needles or syringes become contaminated with virus and are then reused, numbers of people can become infected. The Ebola-Reston virus subtype, which was first recognized in a primate research facility in Virginia, may have been transmitted from monkey to monkey through the air in the facility. While all Ebola virus subtypes have displayed the ability to be spread through airborne particles (aerosols) under research conditions, this type of spread has not been documented among humans in a real-world setting, such as a hospital or household.What are the symptoms of Ebola hemorrhagic fever? The signs and symptoms of Ebola HF are not the same for all patients. The table below outlines symptoms of the disease, according to the frequency with which they have been reported in known cases. Time Frame Symptoms that occur in most Ebola patients Symptoms thatoccur in some Ebola patients Within a few days of becoming infected with the virus: high fever, headache, muscle aches, stomach pain, fatigue, diarrhea sore throat, hiccups, rash, red and itchy eyes, vomiting blood, bloody diarrhea Within one week of becoming infected with the virus: chest pain, shock, and death blindness, bleeding Researchers do not understand why some people are able to recover fromEbola HF and others are not. However, it is known that patients who die usually have not developed a significant immune response to the virus at the time of death. How is Ebola hemorrhagic fever clinically diagnosed? Diagnosing Ebola HF in an individual who has been infected only a few days is difficult because early symptoms, such as red and itchy eyes and a skin rash, are nonspecific to the virus and are seen in other patients with diseases that occur much more frequently. If a person has the constellation of symptoms described in the table above, and infection with Ebola virus is suspected, several laboratory tests sh...
