Later, the disease was discovered to be the cause of illness in the Congo in 1969. Following this, the disease was named as Crimean-Congo hemorrhagic fever (CCHF).
How is Congo Fever transmitted?

It is generally transmitted from one animal to another through bite of the Hyalomma tick, an external parasite that lives by feeding on the blood of mammals and birds.
The disease can also be contracted through contact with viraemic animal tissues, animal tissue where the virus has entered the bloodstream during and immediately post-slaughter of animals.
How is the disease transmitted to humans?
The Congo fever is transmitted to humans to through contact with the blood of infected animals and by eating the meat of infected animals.
Is human-to-human transmission of the virus possible?
