As cases of West Nile virus increase in the tri-state area, health officials say there are many ways people can prevent the spread of the disease.

The Centers for Disease Control and Prevention says there have been 49 cases in 15 states so far this year.

Ways to mitigate risk include:

Doctors say people can feel symptoms 3 to 15 days after they have been bitten by an infected mosquito. Most cases are considered mild, with people suffering from a fever, headache, body aches, vomiting, diarrhea and or a rash.

They say in some cases, the virus can impact a person's brain and nervous system. It can also cause brain swelling and damage or even death.

Anyone experiencing symptoms should reach out to their doctor, especially if they have a compromised immune system.
