Deer-Tick-Borne Illnesses on the Rise in the Northeast

Uncategorized By Jun 13, 2023

Deer-tick related illnesses, including Lyme disease and anaplasmosis, are increasing in the US Northeast, with the spike attributed to climate change and human development activities such as deforestation and construction. A 2019 report by the Centers for Disease Control and Prevention reveals seven-fold increase in cases of babesiosis and tripled cases of anaplasmosis between 2009 and 2017. The rise in illness highlights the importance of effective prevention and treatment, including minimising exposure to tick-infested environments, using personal tick repellents and antibiotics in early stages of the illness. There is currently no commercially available vaccine for tick-borne illnesses.

Deer-Tick-Borne Illnesses on the Rise in the Northeast

The Northeast region of the United States has always been a hot spot for deer-tick related illnesses like Lyme disease and anaplasmosis. However, recent studies indicate that the situation is getting worse, and deer-tick-borne diseases are on the rise in the region.

The extent of the problem

The Centers for Disease Control and Prevention (CDC) reported that there was a significant jump in confirmed cases of Lyme disease in the Northeast between 2013 and 2017. In the most severely impacted states, like Massachusetts and Rhode Island, the incidence rate of Lyme disease more than doubled over that time frame.

In addition to Lyme disease, other tick-borne illnesses like babesiosis and anaplasmosis are also spreading rapidly in the region. According to a 2019 report from the CDC, cases of babesiosis have increased almost 7-fold in the northeastern United States between 2009 and 2017. Similarly, cases of anaplasmosis tripled during the same time frame.

Factors contributing to the problem

The rapid proliferation of deer-tick-borne illnesses can be attributed to several factors. One of the primary drivers is climate change. Warmer temperatures and humidity levels provide a conducive environment for ticks and their hosts to thrive.

In addition to environmental factors, human development activities like deforestation and construction can also contribute to increased tick populations. These activities remove the natural habitats of predators like foxes and opossums that keep the deer population in check and, in the process, limit the number of ticks in the environment.

Prevention and treatment options

The increase in deer-tick-borne illnesses in the Northeast underscores the need for effective prevention and treatment options. One of the most effective ways to prevent tick bites is by minimizing exposure to tick-infested environments. This includes avoiding wooded areas and high grass where ticks are known to inhabit.

For individuals who are exposed to tick-prone areas, it is important to use personal tick repellents like DEET and permethrin. Additionally, wearing long-sleeved shirts and pants tucked into socks can help minimize the amount of skin that is exposed to ticks.

When it comes to treatment, early diagnosis and treatment of Lyme disease and other tick-borne illnesses can be facilitated by awareness of symptoms and seeking prompt medical attention. Symptoms of Lyme disease include fever, fatigue, and a distinctive rash that resembles a bull’s eye.


What are the symptoms of Lyme disease?

The most common early symptoms of Lyme disease are fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, the infection may spread to other parts of the body and lead to more severe symptoms like arthritis and heart palpitations.

What is the best way to prevent tick bites?

One of the most effective ways to prevent tick bites is by avoiding areas where ticks are prevalent, such as wooded or grassy areas. Additionally, wearing long-sleeved shirts and pants tucked into socks can help prevent ticks from attaching to the skin. The use of personal tick repellents like DEET and permethrin can also be effective.

What is the treatment for Lyme disease?

The treatment for Lyme disease typically involves a course of antibiotics. The specific antibiotic used will depend on the stage and severity of the disease. Treatment is most effective when started as early as possible after the onset of symptoms.

What is the outlook for individuals with tick-borne illnesses?

Most individuals with tick-borne illnesses like Lyme disease and anaplasmosis respond well to early treatment with antibiotics. However, if left untreated or if there is a delay in diagnosis, these illnesses can lead to more severe health complications.

Can tick-borne illnesses be prevented with vaccines?

Currently, there are no commercially available vaccines for most tick-borne illnesses. However, there are vaccines available for Lyme disease that are currently in clinical trials and could be available in the future.
