The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.

Where did Ebola start?

Ebola virus was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of Congo. Since then, the virus has been infecting people from time to time, leading to outbreaks in several African countries.

How did the swine flu start?

In 1998, swine flu was found in pigs in four U.S. states. Within a year, it had spread through pig populations across the United States. Scientists found this virus had originated in pigs as a recombinant form of flu strains from birds and humans.

How did humans get Ebola?

The first human case in an Ebola outbreak is acquired through contact with blood, secretions organs or other bodily fluids of an infected animal. EVD has been documented in people who handled infected chimpanzees, gorillas, and forest antelopes, both dead and alive, in Cote d’Ivoire, the Republic of Congo and Gabon.

What country did swine flu come from?

The swine-origin influenza A (H1N1) virus that appeared in 2009 and was first found in human beings in Mexico, is a reassortant with at least three parents. Six of the genes are closest in sequence to those of H1N2 ‘triple-reassortant’ influenza viruses isolated from pigs in North America around 1999-2000.

What stopped Ebola?

Engaging local leaders in prevention programs and messaging, along with careful policy implementation at the national and global level, helped to eventually contain the spread of the virus and put an end to this outbreak. Liberia was first declared Ebola-free in May 2015.

How many did the bird flu kill?
