X24: Contact with centipedes and venomous millipedes (tropical)

Contact with centipedes and venomous millipedes, which are prevalent in tropical regions, can lead to a variety of medical conditions. These arthropods are known to carry venom, which is released through their bites or stings. While each individual's reaction to this venom can vary, common symptoms of exposure often include localized pain, redness, swelling, and itchiness at the bite site. More severe systemic symptoms can occur, and may involve chills, fever, or an elevated heart rate. In some cases, individuals may also experience increased sensitivity to the venom, leading to heightened and more severe reactions. These conditions primarily affect the integumentary system, which includes the skin, hair, nails, and related muscles and glands, but can also impact the cardiovascular and immune systems. Disease progression can vary broadly depending on the individual's health status, the type and quantity of venom, and the speed of the reaction.
