Whether a tick bite will kill a person is generally based on the severity of the tick bite, the patient’s own body resistance, and the patient’s treatment of the wound in a timely manner and other factors to be objectively analyzed: First, if the degree of the tick bite is light, the patient’s own body resistance is strong, and the wound is taken to a thorough debridement. There is no serious localized infection, and the body does not show symptoms of poisoning such as chills and high fever. In this case, the patient’s condition is mild and death will not occur. Second, if the patient is old and weak, after being bitten by ticks, localized obvious infection occurs, and the patient does not pay enough attention to it, and does not carry out timely debridement of the wound. At this time, the local toxins may be absorbed into the blood, causing the patient to develop infectious shock, endangering the patient’s life and even death.
