Is a bacterial infection that can be contracted from ticks. The tick must bite you in order to transmit the disease. Removing a tick as soon as you can (within one to two days) reduces the risk of infection. If you live in an area that has ticks, make it a habit to check your body and clothes every day. The symptoms are the same, whether you are pregnant or not. The first sign is typically a red, round-shaped rash around where the tick bit you. It usually appears between 7 and 14 days after the bite. Studies indicate there is a very slim risk that your baby will be infected if you receive the right antibiotics.
Contact your healthcare provider if you suspect you have borrelia.
