Symptoms of Lyme and other tick diseases to watch for
You probably know that Lyme disease is the scourge of the Northeast and upper Midwest. But did you know that most cases of Rocky Mountain spotted fever are reported in six states that are nowhere near that mountain range?
It’s important to keep up your guard for tick diseases even now, as ticks can be active as long as temperatures are 40° F or higher, according to the Centers for Disease Control and Prevention. Everyone should take precautions, but especially hunters, hikers, and people cleaning up fall leaves.
One of the best ways to prevent tick bites in the first place is to apply insect repellent. “A lot of people are nervous about using it on their children,” says Christina Nelson, M.D., a medical epidemiologist in the CDC’s bacterial diseases branch in the Division of Vector-borne Diseases. “But they’re safe and effective when used appropriately. I use them on my own children and I think they’re important.” Of the repellents Consumer Reports tested, products containing 20 percent picaridin, 30 percent oil of lemon eucalyptus, and 15 percent deet were top performers.
Tick diseases are not to be taken lightly. If left untreated, a Lyme disease infection can spread to your joints, heart, and the nervous system. Rocky Mountain spotted fever can become deadly if not treated in the first few days.
Following are five of the most common tick diseases, where they occur most often, symptoms to watch for, and treatment suggestions from our medical experts.
