Tick bites are usually treated symptomatically if only itchy, red and swollen skin occurs, but we need to be alert to the possible serious consequences of tick bites such as muscle paralysis and infection. Different people will experience different symptoms after being bitten by ticks, and the harm caused can be mild or severe. If the tick bite only manifests as itching and redness of the skin, it is generally not too serious after prompt treatment. If the tick secretes some neurotoxins through saliva during the process of biting, it will lead to the motor nerve fiber conduction disorder of the bitten person, resulting in muscle paralysis, such as respiratory muscle paralysis, which can cause respiratory failure, which is a serious consequence. Ticks carry various viruses such as Hantavirus, Seoul virus, Puumala virus, etc. Tick bites may transmit some infectious diseases. Therefore, if you are bitten by a tick, it is recommended that you visit a hospital in time and under the guidance of a doctor.
