Adult Ixodes ticks are most active during the cooler months of the year. While questing, ticks hold onto leaves and grass by their lower legs. They hold their upper pair of legs outstretched, waiting to climb onto a passing host. When a host brushes the spot where a tick is waiting, it quickly climbs aboard. It then finds a suitable place to bite its host. The lifecycle of blacklegged ticks Ixodes scapularis and Ixodes pacificus generally lasts two years. During this time, they go through four life stages: egg, six-legged larva, eight-legged nymph, and adult.
After the eggs hatch, the ticks must have a blood meal at every stage to survive. Blacklegged ticks can feed from mammals, birds, reptiles, and amphibians. The ticks need to have a new host at each stage of their life, as shown below:. Skip directly to site content Skip directly to page options Skip directly to A-Z link. Lyme Disease.

There is no evidence that Lyme disease is transmitted from person-to-person.
For example, a person cannot get infected from touching, kissing, or having sex with a person who has Lyme disease. Untreated Lyme disease during pregnancy can lead to infection of the placenta. Spread from mother to fetus is possible but rare. There are no documented cases of Lyme transmission via a blood transfusion.
But the Lyme spirochete Borrelia burgdorferi has been isolated from human blood, and an older research study found that Lyme spirochetes could survive the normal blood bank storage procedures. 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:. Lyme is an underreported epidemic in the United States. Diagnosis is challenging because Lyme symptoms are like those of many other diseases. The one documented exception is that pregnant women can transmit the infection to their fetus.

Lyme disease natural treatments: Do they exist? While most bug bites cause only mild symptoms, some bug bites can transmit disease. Read on to learn more about symptoms and how to prevent bug bites.
Early disseminated Lyme disease is the stage in which the bacteria that cause Lyme disease have spread throughout your body. The best way to prevent Lyme disease is to avoid areas where deer ticks live, especially wooded, bushy areas with long grass. You can decrease your risk of getting Lyme disease with some simple precautions:.
Use insect repellents. Parents should apply repellant to their children, avoiding their hands, eyes and mouth. Keep in mind that chemical repellents can be toxic, so follow directions carefully. Apply products with permethrin to clothing or buy pretreated clothing. Check your clothing, yourself, your children and your pets for ticks. Be especially vigilant after spending time in wooded or grassy areas. Deer ticks are often no bigger than the head of a pin, so you might not discover them unless you search carefully.
It's helpful to shower as soon as you come indoors. Ticks often remain on your skin for hours before attaching themselves. Showering and using a washcloth might remove unattached ticks. Gregory Poland, director the Mayo Clinic Vaccine Research Group, says there was a vaccine for humans, but it was withdrawn.
It's illogical. It's the bite of an infected blacklegged tick or deer tick that's responsible for making so many people sick with Lyme disease. There are no plans at this time for a new Lyme vaccine in the U. A vaccine, VLA15, is being developed in Europe. Now they'll do phase 3 clinical testing, which means they go to the FDA, get approval, and they'll do very large studies.
Poland says it might take five years or more before a Lyme disease vaccine is ready for humans. Until then, it's important to be tick smart. And they will climb up the nearest object, like this blade of grass here. Mayo Clinic parasitic diseases expert Dr. Bobbi Pritt suggests permethrin for your clothing and gear. Use permethrin on materials and DEET on skin. Spray the DEET repellent on exposed skin, including your legs and hands. Avoid your face, but be sure to protect your neck.
Then, tuck your pants into your socks. And, on your hike, remember to avoid areas where those questing ticks may be perched. Mayo Clinic does not endorse companies or products.
