Marburg is a rare but deadly disease spread through direct contact with blood and body fluids of a person who is sick with Marburg or through needles or other objects that have been contaminated with the virus. Marburg is not spread through the air or by water, or by food, in general.

Signs and symptoms of Marburg include but are not limited to fever, headache, muscle pain, vomiting, diarrhea, rash, stomach pain, bleeding, or bruising. These signs and symptoms may appear up to 21 days after exposure. A person infected with Marburg is contagious once symptoms appear.
