Tickborne Diseases: Definition, Risks, Prevention

What are Tickborne Diseases?

Tickborne diseases are caused by bacteria, viruses, or parasites transmitted to humans through the bite of infected ticks. These diseases often begin with symptoms like fever, fatigue, and muscle aches. If left untreated, they can lead to serious complications affecting various organs and systems in the body.

Types

There are several types of tickborne diseases, each caused by different pathogens. These illnesses can be bacterial, viral, or parasitic, depending on the type of tick and the region where exposure occurs. Without proper pest control measures, businesses may face increased exposure to ticks and potential outbreaks that affect workforce health and productivity.

Lyme disease is the most common tickborne disease and is caused by bacteria transmitted through the bite of infected black-legged ticks. Other types may present different symptoms and risks, requiring region-specific awareness and prevention.

Risks for Workers

Tickborne diseases pose significant health risks to employees who work outdoors or in areas with high vegetation, such as construction sites, farms, or utility locations.  The lack of awareness about these diseases and proper prevention or pest management protocols can lead to higher absenteeism and medical costs.

Additionally, businesses operating in wooded or grassy regions may be liable if workers contract illnesses due to inadequate safety practices. Tickborne diseases also impact operational timelines, as illnesses and health inspections can delay projects. Proactive risk management is essential to minimize exposure and ensure compliance with workplace safety standards.

Occupational Risk Factors

Employees in certain industries are more at-risk for tickborne diseases, which is why it’s important for employers to account for these risks. That said, there are other risk factors to consider aside from industry, such as the following:

Outdoor Exposure Frequency and Duration

Workers who spend extended periods outdoors are at higher risk of encountering ticks, especially in warm months when tick activity peaks. Frequent and prolonged exposure increases the likelihood of tick bites and repeated contact with infested areas. The more time spent in high-risk environments, the greater the chance of contracting a tickborne disease.

Terrain and Vegetation Type

Areas with tall grass, dense shrubs, or wooded terrain are ideal habitats for ticks and increase the chances of worker exposure. These environments make it easier for ticks to attach to clothing or skin undetected. Businesses operating in such landscapes need targeted prevention strategies to reduce risks.

Use of Personal Protective Equipment

Proper use of Personal Protective Equipment (PPE), such as long sleeves, pants, and tick repellents, significantly lowers the risk of tick bites. However, inconsistent or incorrect use of PPE can leave workers vulnerable to exposure. Regular training and enforcement of protective measures are essential for effective prevention.

Regulatory Framework and Employer Responsibilities

In the US, employers have a responsibility to protect workers from tickborne diseases under the Occupational Safety and Health Administration (OSHA) General Duty Clause, which requires a workplace free from recognized hazards. While there is no specific OSHA standard for tickborne illnesses, related rules cover PPE, training, and illness recordkeeping. OSHA also issues guidance on preventive practices such as using repellents, providing tick removal procedures, and promoting employee awareness.

On top of OSHA requirements, the US Fish and Wildlife Service provides policies that require employers to provide tick-bite prevention training and maintain training records through approved systems. Employers must also ensure that any tick bites or symptoms are followed by prompt medical attention and reported in the Safety Management Information System (SMIS). Under this, workers are also expected to wear PPE, conduct regular buddy checks, and report any incidents to supervisors for proper documentation.

Tickborne Disease Prevention Strategies

Tickborne Disease Prevention Strategies

Tickborne diseases such as Lyme Disease have been on the rise in the past decade, especially in the US. This highlights the importance for employers and employees to put in the effort to reduce the risk of contracting these diseases. Below are key prevention strategies that can help reduce and prevent their risks:

Environmental Controls

Modifying the work environment can reduce tick habitats and minimize exposure. This may include mowing tall grass, clearing brush, and managing leaf litter in outdoor work areas. Keeping work zones well-maintained creates a less favorable environment for ticks to thrive.

Pest Inspections

Regular pest inspections help identify areas with high tick activity before exposure occurs. Inspections can be conducted by trained staff or pest control professionals who monitor vegetation, wildlife presence, and tick density. Early detection, with help from digital solutions and inspection forms, allows for timely action to reduce tick populations and protect workers.

Personal Protective Measures

Wearing long-sleeved shirts, pants tucked into socks, and light-colored clothing can help prevent ticks from reaching the skin and make them easier to spot. Using EPA-registered insect repellents on skin and permethrin-treated clothing adds an extra layer of protection. Workers should also perform regular tick checks during and after outdoor tasks, ideally with digital checklists to ensure everyone is aware of each check and inspection.

Proper Tick Removal

Removing ticks promptly and correctly reduces the risk of disease transmission. Ticks should be grasped with fine-tipped tweezers as close to the skin as possible and pulled out slowly without twisting. After removal, the bite area should be cleaned and the tick saved for identification if symptoms develop.
