## Core Concept
Ebola virus transmission primarily occurs through direct contact with infected bodily fluids, such as blood, sweat, and saliva. The virus can also be transmitted through contact with contaminated objects, like needles or medical equipment. Understanding the modes of transmission is crucial for implementing effective infection control measures.

## Why the Correct Answer is Right
The correct answer, ., implies that airborne transmission is not a recognized mode of Ebola virus transmission. Ebola is not considered an airborne pathogen like influenza or tuberculosis; it requires direct contact with infected materials for transmission to occur.

## Why Each Wrong Option is Incorrect
- **Option A:** Direct contact with infected bodily fluids is a well-documented mode of Ebola transmission. This can include touching infected patients or handling their contaminated belongings.
- **Option B:** Contact with contaminated objects or surfaces can also lead to transmission if the infected material comes into contact with broken skin or mucous membranes.
- **Option C:** This option likely refers to another mode of transmission similar to A or B, reinforcing that Ebola's primary transmission routes involve direct contact.

## Clinical Pearl / High-Yield Fact
A critical point to remember is that **Ebola is not spread through the air**, which distinguishes it from highly contagious and airborne pathogens. This knowledge is vital for healthcare workers to don appropriate personal protective equipment (PPE) and for public health officials to develop effective quarantine and treatment protocols.

## Correct Answer: . Airborne transmission
