As COVID-19 and flu season ramp up, another virus is making headlines: "Bleeding eyes" virus, also known as the Marburg virus. The U.S. State Department is warning Americans against traveling to Rwanda due to an outbreak. So far, 15 people have died from the disease. A travel alert from the Centers for Disease Control and Prevention (CDC) urges people to "practice enhanced precautions" if traveling to Rwanda, noting that Marburg virus disease is "rare and deadly." Marburg virus disease is a rare and severe viral hemorrhagic (i.e. bleeding) fever that impacts people and other primates, including monkeys and apes, per the CDC.
