Trans-Species Pathogenic Threats (02:01)


Mystery viruses H7N9, Mers-CoV, and Ebola recently emerged from the animal kingdom. Scientists race against the clock to learn their origins, and how to prevent their spread.

Pandemic Response System (01:40)

WHO specialists monitor new pathogenic strains. They currently follow H7N9 in China using interactive maps.

Mers-Coronavirus (01:21)

The Mers-CoV was first identified in Saudi Arabia. Pilgrims to Mecca could spread it globally.

Investigating Viral Origins (01:47)

Dr. Peter Daszak tracks new pathogens transmitted from animals. The Mers-CoV is linked to camels and bats.

Pandemic Fears (00:49)

Hear mortality statistics of the Spanish Flu. Since then, improved sanitary conditions, vaccinations, and antibiotics have helped control outbreaks.

Virus Hot Spots (02:20)

In the 1980s, HIV proved epidemics are still a threat. Mers and N7N9 follow a similar emergence pattern; animals transmit pathogens in areas of rapid habitat change.

Filovirus Reservoirs (04:14)

Central Africa is home to Ebola and Marburg. Franceville International Center for Medical Research (CIRMF) scientists collect bat species to test for hemorrhagic fever pathogens.

Ebola Reservoir (00:56)

Researchers first believed monkeys harbored the virus. In Gabon in 1996, children became infected from a chimpanzee.

Ebola Outbreaks (00:52)

The virus appears in remote Central Africa. Scientists test animals near infected villages to search for its origins.

Ebola Research (02:14)

CIRMF researchers study hemorrhagic fever blood in local laboratories. They found the virus in bats; they study all viruses specific to each species to learn about replication.

Search for the Next Pandemic (01:32)

Daszak says there are 300,000 undiscovered viruses. His team analyzes new strains from viral hot spots at Columbia University.

Mers Virus Origins Research (02:17)

Virology Professor Ian Lipkin and Daszak study bats known to carry the Mers virus. They explain the human-to- human transmission process and why pandemics must be halted in the wild.

SARS Panic (01:05)

In 2003, a pathogen in the Coronavirus family was transmitted to humans. Lipkin recalls the deserted Beijing streets.

SARS Outbreak Epicenter (01:19)

Professor Malik Peiris recalls the first case in Hong Kong. The patient infected 15 other people who traveled abroad and started outbreaks.

Avian Flu Outbreak (02:14)

Hong Kong took H7N9 seriously in 2013. The virus wasn't yet transmittable among humans, but authorities feared it would combine with seasonal flu and become highly infectious.

Viral Vectors (02:40)

Wild birds were H7N9 reservoirs; poultry transferred the virus to humans. Daszak observes unsanitary conditions and potential high exposure at a chicken market in China.

Crossing the Species Barrier (02:27)

Chinese poultry farmers bring free range birds inside the house, risking infection. Viruses develop faster than vaccines.

Testing for Avian Flu (01:12)

Daszak takes samples from chickens on a Chinese farm, searching for viral hot spots

Controversial Pathogen Research (02:17)

In a race against viruses, Dutch scientists are creating mutations of H7N9—sparking bioterrorism fears.

Vaccination Research (02:36)

Dutch scientists mutated H5N1 for human-to-human transmission. A project leader believes his work in creating anti-viral drugs outweighs bioterrorism threats.

Creating a Monster (01:08)

WHO recently lifted a moratorium on lab engineered viruses. A French bioterrorism expert says the pandemic risk outweighs research benefits.

Ebola Threat (01:51)

A new viral strain has surprised WHO. Officials meet to discuss its spread in West Africa.

Guinea Cases (01:18)

Ebola was reported in Conakry—the first time it's reached a major city. A French virologist explains how infection pathways could overwhelm the health system.

Ebola "Village" (02:13)

At a Doctors Without Borders facility in Conakry, doctors care for the dying and isolate potential patients. Learn about protective measures during testing and diagnosis.

International Response (00:42)

A French doctor discusses the importance of halting Ebola's spread.

Ebola Survivor (01:11)

Doctors cured a few cases in June 2014; Bakary Oulare describes his brush with death.

One Health Concept (00:43)

With viruses transmitted from bats and birds, scientists recognize animal and human interdependence—a link shedding new light on environmental degradation.

Rat Virus Research (01:12)

French researchers study rats in Thailand. Habitat change caused several species extinctions—but new illnesses are emerging in villages.

Rodent Viral Threat (01:03)

As agriculture decreases pathogenic diversity in Thailand, remaining strains strengthen and transmit to fleas, ticks, and mites—increasing human infection risk.

New Pandemic Paradigm (01:17)

The One Health approach to pathogens provides incentive to slow environmental changes and habitat destruction.

When is a new global epidemic going to strike? This in-depth investigation examines the invisible threat of new viruses emerging in the animal kingdom at an unprecedented rate. In the space of 60 years, over 350 new infectious diseases have appeared, including SARS, H1N1, H5N1, and Ebola. This film traces three threatening viruses that have been transmitted from animals to humans: the H7N9 flu virus in Asia; the Mers-CoV virus, related to SARS, active in the Middle East; and the Ebola virus, which is striking terror in West Africa. Researchers are recognizing that a “one health” approach, in which we look at habitat loss and ecosystem breakdown as well as human health, will be crucial for prevention. (53 minutes)
