Bacteria have been around for at least 3.5 billion years, making them the oldest known life-form on the planet.

However, one particular group of bacteria, the cyanobacteria or “blue-green algae,” have left a fossil record that extends far back into the Precambrian – the oldest cyanobacteria-like fossils known are nearly 3.5 billion years old, among the oldest fossils currently known.

They existed 3.5 billion years before humans evolved on Earth. They’re neither dead nor alive. Their genetic material is embedded in our own DNA, constituting close to 10% of the human genome.

Health authorities have rushed to respond to the cases in Guinea, anxious to prevent a repeat of the last outbreak in West Africa, which killed more than 11,300 people, mostly in Guinea, Sierra Leone and Liberia in the worst Ebola epidemic on record.

Is Ebola contagious? Ebola is contagious. The virus spreads through direct contact (via broken skin or mucous membranes, in the nose, mouth, or eyes). Blood or body fluids from infected individuals are capable of causing infection in others.

Ebola is not a respiratory disease and is not spread through the airborne route. There is no evidence that Ebola is spread by coughing or sneezing.

Is it true that Ebola cannot exist in cold climates like Minnesota in the winter? Unfortunately, Ebola can exist in places such as Minnesota, because it lives inside the human body, which is roughly the same temperature regardless of where people live, and is transmitted from person to person.

Ebola is easily destroyed outside of the body, experts say. UV light, heat and exposure to oxygen all deactivate the virus over time. CDC Director Dr.

Have there ever been cases in the United States? Eleven people in the U.S. were treated for the Ebola virus during the West Africa Ebola outbreak between 2014 and 2016, according to the CDC. Two of those people died.
