On the other hand, there have been more than 30 cases of transfusion-transmitted babesiosis, a parasite coinfection of the same black-legged tick that transmits Lyme. A pregnant woman with untreated Lyme can transmit the infection to the fetus. But if they receive adequate treatment for Lyme, adverse effects are unlikely. A study of 66 pregnant women found that untreated women had a significantly higher risk of adverse pregnancy outcomes. Infection from the mother to the fetus can occur within the first three months of pregnancy, according to Donta.
If the mother is untreated, the infection would result in congenital abnormalities or miscarriage. But dogs and other domestic animals can bring Lyme-carrying ticks into your home. These ticks could attach to you and cause infection. The symptoms of Lyme vary widely and mimic those of many other diseases. Here are some common symptoms:.

Preventing Tick Bites. Individuals being treated for Lyme disease with an antibiotic should not donate blood. Individuals who have completed antibiotic treatment for Lyme disease may be considered as potential blood donors. Information on the current criteria for blood donation is available on the Red Cross website external icon.
Although dogs and cats can get Lyme disease, there is no evidence that they spread the disease directly to their owners. However, pets can bring infected ticks into your home or yard.
Consider protecting your pet, and possibly yourself, through the use of tick control products for animals. You will not get Lyme disease from eating venison or squirrel meat, but in keeping with general food safety principles, always cook meat thoroughly. Note that hunting and dressing deer or squirrels may bring you into close contact with infected ticks. There is no credible evidence that Lyme disease can be transmitted through air, food, water, or from the bites of mosquitoes, flies, fleas, or lice.
Ticks not known to transmit Lyme disease include Lone star ticks Amblyomma americanum , the American dog tick Dermacentor variabilis , the Rocky Mountain wood tick Dermacentor andersoni , and the brown dog tick Rhipicephalus sanguineus.
How ticks find their hosts. How ticks attach to their hosts. The tick feeding process makes ticks very good at transmitting infection: Depending on the tick species and its stage of life, preparing to feed can take from 10 minutes to 2 hours. When the tick finds a feeding spot, it grasps the skin and cuts into the surface. The tick then inserts its feeding tube. Many species also secrete a cement-like substance that keeps them firmly attached during the meal.
The feeding tube can have barbs, which help keep the tick in place. If the tick is in a sheltered spot, it can go unnoticed. A blacklegged tick will attach to its host and suck the blood slowly for several days.
If the host animal has certain bloodborne infections, such as the bacteria that cause Lyme disease, the tick may ingest the pathogen and become infected. If the tick later feeds on a human, that human can become infected. After feeding, the blacklegged tick drops off and prepares for the next life stage.
