Why is there no vaccine or drug for Ebola?
There are several promising drugs and vaccines in development, but since Ebola is less common—and research about it is not well funded—there is no drug or vaccine that has been approved for use in humans. One experimental serum was used by the two American patients, but there’s not enough for widespread use yet. Many of the other drugs and vaccines have not yet been tested in humans. The WHO is meeting next week to discuss whether experimental treatments should be used during this outbreak.
What does the virus do to the human body?
The virus is systemic. That means it can move to and affect every part of the body causing direct damage to organs as well as internal bleeding. This causes shock, which drops a person’s blood pressure and causes multisystem organ failure.
How were the two American patients brought to the US safely?
The two Americans were evacuated out of Liberia in special planes equipped with the necessary medical equipment to sustain their health and keep them isolated. After the plane landed, they were taken in a similarly equipped ambulance to Emory University Hospital, which has a specially built isolation unit meant to treat patients who have been exposed to severe infectious diseases.
