Safeguard Yourself from Ticks, Lyme, and other Tick-borne Diseases

By Jennifer Kraus, MD, Virtua Health Infectious Disease Specialist 

Each spring, tick season predictions ramp up, and most people cite harsh winter weather for a lighter tick season or mild winter weather for a heavy tick season. 

However, according to the Centers for Disease Control (CDC), it's complicated to predict the number of Lyme disease or other tick-borne infections, including how an upcoming season will compare with previous years. Many factors can affect those numbers, including temperature, rainfall, humidity, and the availability of hosts for the ticks to feed on, such as mice, deer, and other animals. 

What IS known is that deer ticks are everywhere. In fact, New Jersey is third in the country for reported tick-borne disease from 2004-2016. These ticks transmit Lyme disease—and other serious tick-borne diseases—which are treatable if caught early.

If you're spending more time outside, read the important information below to see how you can protect yourself and your family from ticks and tick bites. 

How Lyme disease is transmitted

Lyme disease is the most common zoonotic (transmitted from animal to human) disease in America. It's caused by the bacterium Borrelia burgdorferi, which is carried by the black-legged deer tick that's common in New Jersey and surrounding areas.

People often encounter deer ticks after spending time in heavily wooded areas, but you don't need to be a hiker to be bitten by one. Those with pets should know that a cat or dog can easily bring a tick into the house. This means you should be on alert even if you don't spend much time outdoors. 

Spraying your skin with a DEET-containing insect repellent, or spraying your clothing (and clothing only) with a permethrin-containing insect repellent, are options for keeping ticks at bay. In addition, wearing long sleeves and pants, hats, and light-colored clothing make it easier to spot the ticks on your body and makes it harder for them to attach to your skin.  

What to do if there's a tick on you

If a tick is crawling on you outside and you brush it off, you don't need to be worried about Lyme. The tick must be attached for at least 36 hours to spread the disease to you. 

Check your body and clothes for ticks after spending time in a high-risk environment. If you find a tick attached to you, remove the entire tick with tweezers to ensure you don't come into contact with Lyme bacteria. 

But, keep in mind, ticks are good at hiding. So check your scalp, back, and skin folds—especially the back of the knee, the underarm, and between the legs.

What are the symptoms of Lyme disease?

These are early symptoms of Lyme disease:

  • A "bulls-eye" rash
    A bulls-eye rash is one of the most recognizable symptoms of Lyme. This can start any time from a few days to 2 weeks after the tick bite. This rash will expand outward and may turn into a red outer ring with a clear area inside it. Looking for that pattern is important because almost all people will have some degree of redness and hypersensitivity to a tick bite, as with any insect bite. But, it's also important to note that this rash usually isn't tender. 
  • A flu-like reaction 
    This can include fever, headache, neck stiffness, and fatigue. 

These are the symptoms of the later stages of Lyme disease and can occur months after infection (if untreated):

  • Joint pain with swelling
    This tends to affect the large, weight-bearing joints like the hip and especially the knee. It mimics arthritis, except it's usually accompanied by swelling, and again, it will tend to be less painful than it looks.
  • Cranial nerve inflammation
    Cranial nerve inflammation is more unusual but tends to affect the nerves of the face, affecting facial movements. If you experience this, you should see your doctor right away.
  • Encephalitis (brain inflammation) and confusion
    Encephalitis can result from infection or the immune system attacking the brain. More severe cases can cause confusion, severe headache, high fever, stiff neck, and other symptoms.

How Lyme disease is treated

Generally, Lyme disease is easily treated with 10-14 days of oral antibiotics. Depending on what type of Lyme disease you have and what area of the body is affected, this will determine how long you're treated and whether you require intravenous versus oral antibiotics for a longer course. Also, a single dose of the oral antibiotic doxycycline given when someone COMES IN with an engorged deer tick still attached but showing no other symptoms is highly effective at preventing disease.  

If you're not feeling any better after 2-3 weeks of oral antibiotics, there's a good chance you don't have Lyme. In this case, continuing to take doxycycline likely won't help, and other diseases should be ruled out with the expert guidance of an infectious disease specialist. 

Beware of these other tick-related diseases

The same tick that carries Lyme disease can also carry other diseases that you should be aware of:

  • Ehrlichiosis and anaplasma can cause a flu-like illness that may be mild or may cause symptoms of headache, chills, fever, rash, and fatigue. These symptoms can develop up to 2 months after the tick bite. Much like Lyme disease, this is treatable with the oral antibiotic doxycycline, but you should see your physician.
  • Babesiosis is another tick-borne illness to think about during warmer months. You may develop symptoms 1-6 weeks after a tick bite, including fatigue, fever, joint aches, and abdominal pain. People who would be at risk for severe disease include those who have had their spleen removed, those over age 50, anyone on immunosuppressive drugs, and patients with HIV. This is usually treated with a combination of antibiotics.
  • Powassan virus is transmitted by the same tick that carries Lyme disease and can infect all age groups from the very young to the very old. The most common symptoms are fever and headache, but people may also get muscle aches and a mild rash. Unfortunately, this virus can't be treated with antibiotics, and there's no vaccine available at this time. If you think you or a family member have been bitten by a tick and have the above symptoms that progress to changes in mental status, you want to go to the nearest emergency room so a doctor can evaluate you.
  • Other tick-borne diseases: With the warmer weather we've experienced in the last few years, some scientists say that tick-borne diseases have flourished. Despite our location, we've seen Rocky Mountain spotted fever in the Northeast. Along with fever and muscle aches, Rocky Mountain spotted fever also is associated with a headache and rash. In addition, emerging illnesses include the Heartland virus and the tick-borne relapsing fever caused by Borrelia miyamotoi. Symptoms are similar to the other tick-borne illnesses. As always, speak to your primary care doctor and, if needed, he or she can refer you to an infectious disease doctor for further evaluation.  

If you've been bitten by a tick and have the above symptoms and risk factors, you will want to speak to your doctor.
