Explanation:

This type of disease is transmitted by bite of the ticks.

To prevent it, a person should wear long sleeved clothes and jeans and pants, and to use insect repellant. To decrease the infection or the risk of it, a person will probably be on some type of medication for a certain period.

When it comes to symptoms, a red circle will occur at the place where a person was bitten around 7 days after the biting, it won't be itchy or painful, and later it will continue to expand ( the red circle ) while some people will simply see the red circle and it will pass as the time goes by.
