During the May Day holiday, many families have to go out and play. Experts suggest that while getting close to nature, be careful of these "little black spots" - be careful not to be bitten by ticks when engaging in outdoor activities. As the weather warms up, ticks are most active from April to September each year, usually appearing in densely vegetated areas such as grass and forests. According to data released by the Institute of Viral Disease Prevention and Control of the Chinese Center for Disease Control and Prevention, ticks can transmit 83 viral, 31 bacterial, and 32 protozoal diseases. Xu Jinghang, chief physician of the Infection Department of Peking University First Hospital, said ticks can carry a variety of viruses, bacteria, Rickettsia and other pathogens, and can cause a variety of infectious diseases after biting the human body, including viral infectious diseases (such as fever with thrombocytopenia syndrome, forest encephalitis), spirochete infectious diseases (such as Lyme disease), etc. "Most of these diseases have fever, but their clinical manifestations have their own characteristics." Xu Jinghang suggests that after being bitten by ticks, the incubation period of some diseases can be as long as one month. If you experience symptoms such as fever, rash, fatigue, muscle soreness, headache, etc. within a few weeks after removing ticks, you should seek medical attention promptly. Xu Jinghang stated that timely removal of bitten ticks can greatly reduce the infection rate. You can use tweezers to get as close to the surface of the skin as possible, clamp the tick and pull it out, disinfect the bitten area as soon as possible, and wash your hands. Due to the inverted spines on the mouthparts of ticks, it is difficult to extract them after piercing the skin and sucking blood. Liu Si, Deputy Chief Physician of the Emergency Department at Peking University First Hospital, said that if the tick bite is very firm, it is recommended to seek medical treatment as soon as possible. Do not handle it yourself by tapping, forcefully pulling, or burning cigarette butts, as it may cause tick mouthparts to remain on the skin. Reduce the harm of ticks and prioritize prevention. Xu Jinghang suggests that if camping or hiking in the wild, try to wear long clothes and pants to reduce skin exposure; It is best to choose light colors for clothing to facilitate the detection of ticks; Avoid prolonged sitting and lying in tick habitats; The use of mosquito repellent containing mosquito repellent can also reduce tick bites. After engaging in activities in grasslands, forests, and other areas, parents should focus on checking their children's exposed skin, and carefully check for any newly added "small black spots" behind their ears, neck, etc. to avoid the hiding of ticks.
