Transmission of this disease to humans may occur after an infected tick bite or contact with an infected animal, most importantly a sick or recently dead monkey. There is no person-to-person transmission.
Monkeys are the primary carrier of the disease. Ticks (Hemaphysalis Spinigera) that live on them, harbour the pathogen and pass it among the monkey population. Monkeys are sure to die once infected.
When infected monkeys die, ticks drop from the bodies to the ground, thereby generating hot spots of infectious ticks that further spread the virus. It is transmitted to humans through the bite of a tick or when humans come in contact with an infected animal. The outbreak of the disease in humans generally occurs in the dry months, from November to May.
Once the human is infected by the virus, it takes three to eight days for symptoms to appear. Patients may experience abnormally low blood pressure, and low platelet, red blood cell and white blood cell count, chills, fever and headache. Severe muscle pain with vomiting and diarrhea.
