After being bitten by a tick, you need to seek medical attention from the dermatology department of a regular hospital, and note that you must not pull the tick off your skin by yourself, otherwise there will be residual mouthparts. The tick will fall off on its own, but if it is forcibly removed there will be residual mouthparts, which will require local anesthetic surgery to remove the tick’s mouthparts. Because tick bites can present with other clinical manifestations, such as fever, blood tests, liver and kidney function, and coagulation are also generally performed. Oral administration of tetracyclines, such as doxycycline 0.1 g, once in the morning and once in the evening, can be effective in preventing clinical manifestations due to tick infection.
