Ebola may cause hemorrhagic fever in patients, which can look like bleeding in the late stages of disease, but not always. Not every person responds the same to the Ebola virus; this is a rare symptom. Because this symptom is so dramatic, it is more often associated with the disease than it is likely to occur. Like many viruses, there are a wide variety of outcomes that may occur, including being asymptomatic.

Clinical signs of Ebola virus may be similar to cold and flu early on. This makes diagnostics essential in responding to and treating these cases. More developed areas of the world have better access to diagnostic tools that are unfortunately unavailable in other places. This is why assay development and distribution is a focal point of our efforts.
