Lyme disease is primarily transmitted through the bite of infected black-legged ticks, commonly found in grassy, wooded, and bushy areas. Jobs that involve working in such environments increase the risk of tick exposure, making the consideration of Lyme disease pertinent when assessing occupational illnesses.

Land surveying, clearing, and grubbing often take place in outdoor settings that can include dense vegetation, shrubbery, and forests—all locations where ticks thrive. Workers in these roles may spend extended periods in close contact with tick habitats, elevating the likelihood of tick bites and potential Lyme disease infection.

In contrast, roofing work, underground mining, and heavy machinery operation typically occur in environments that are less conducive to tick presence, such as elevated areas, subterranean spaces, or well-maintained industrial sites where vegetation is limited. Therefore, these jobs do not present the same level of risk for encountering ticks and subsequently developing Lyme disease as land surveying and related activities do.
