What is the typical incubation period for West Nile virus in humans?

The typical incubation period for West Nile virus in humans ranges from 3 to 14 days following the bite of an infected mosquito. This period reflects the time it takes for the virus to replicate within the host's body before symptoms may begin to manifest.

Understanding the incubation period is crucial for public health surveillance and response, as it helps identify potential outbreaks and informs health officials when symptoms might emerge. By identifying this timeframe, vector control technicians can better assess risk factors and implement measures during active transmission seasons.

The other options suggest incubation spans that either fall under or exceed the established range, making them less accurate in the context of current scientific understanding. The specified 3 to 14 days adequately encompasses the variability in individual responses to the virus, thereby making it the most reliable choice.
