CCHF Transmission

Human infections are due to:

• Direct or indirect contact with infected animal blood (farmers, slaughterhouse workers, veterinarians, etc)
• Tick bites
• Person to person transmission due to direct or indirect contact with skin, mucous membranes, or body fluids of infected patients (blood, saliva, vomitus, urine, stool, semen)

There is a seasonal occurrence in temperate climates from June to September (Spring to Autumn), corresponding to the period of vector activity.
