Could a camel be responsible for your cold?
It’s more possible than you might think.
One of the four common cold viruses in humans — Human coronavirus 229E — likely reached people through the dromedary camel. Scientists believe the virus originated in bats, then spread to camels before infecting humans.
This kind of cross-species jump is called zoonosis — when a disease spreads from animals to humans. The moment it occurs is known as a zoonotic spillover.
And it’s surprisingly common.
Many well-known diseases began in animals, including:
• Rabies from mammals
• Lyme disease from ticks
• Ebola virus disease linked to bats and primates
• COVID-19, also believed to have originated in bats
These pathogens can reach humans through bites, contaminated surfaces, animal waste, or even handling raw animal products.
But here’s the bigger picture.
As humans expand cities, cut down forests, mine resources, and alter ecosystems, wildlife is forced into closer contact with us. The result? More opportunities for viruses to jump species.
In many ways, the greatest driver of emerging infectious diseases is… us.
As the global population grows, protecting natural habitats may also mean protecting ourselves — from the next pandemic.
