Up to 60% mortality rate without treatment … “If you go out, you have to change your clothes”

The time has come to pay attention to the new coronavirus infection (Corona 19) or the “ fall fever tick and rodent-borne infectious disease ” with flu-like symptoms. This disease has a long incubation period of 2 to 3 weeks, and presents symptoms similar to Corona 19, which became prevalent this year, such as fever and loss of appetite.

Above all, tick-borne infectious diseases often have no cure or vaccine, so prevention is the best option. Minimize skin exposure with long sleeves and long pants during outdoor activities such as farming, mowing, and mountaineering, and separate and manage indoor and outdoor clothing. It is good to finish doing laundry and showering as soon as possible after you return home.

Typical tick-borne infectious diseases include tsutsugamushi syndrome and severe febrile thrombocytopenia syndrome (SFTS). Leptospirosis and nephrotic syndrome hemorrhagic fever are among the best among the infectious diseases transmitted by rodents, such as rats.

According to the Korea Centers for Disease Control and Prevention on 19, it was found that 5,5800, or 91.8% of the 6,779 patients with tsutsugamushi, occurred in the past 7 years from 2013 to last year, mainly between September and November. In August, the summer, the average number of patients was just 751, but it increased to 1,451 in September, 18,944 in October, and 32,355 in November, and then decreased again to 3,050 in December.

In tsutsugamushi, hairy mite larvae invade human bodies and cause disease. The incubation period is 7 to 21 days. After the incubation period, a cough, vomiting and a sore throat appear, rashes and scabs appear, and the lymph nodes are enlarged. In general, it is possible to recover if it is treated quickly, but if it is not treated, the death rate increases up to 60%.

Severe febrile thrombocytopenia syndrome (SFTS), which is the same infectious disease transmitted by ticks, that is infected by the bite of a small true Sophie mite that carries a virus, is also called tick disease murderess. When infected with a new virus infection, symptoms such as fatigue, decreased appetite, vomiting, and diarrhea are accompanied by a high fever of 38 degrees or higher after an incubation period of 7 to 14 days. The death rate is approximately 20%, but the death rate can go up to 30% if proper treatment is not achieved because there is no special treatment yet.

Leptospirosis and nephrotic syndrome hemorrhagic fever, which are transmitted through rodents such as rats, also occur mainly in the fall. Leptospirosis becomes infected by exposing wounds on the skin, etc. through contaminated water in the urine of an animal infected with Leptospirosis. Nephrotic syndrome hemorrhagic fever is the excretion of the virus from infected rodents through feces, urine, saliva, etc. It spreads through

Leptospirosis has a variety of symptoms, ranging from mild cold symptoms to Weil’s disease, including jaundice, acute kidney failure, and bleeding from the skin or mucous membranes. In the first stage (sepsis), leptospira is detected in the blood, cerebrospinal fluid and most tissues, and flu-like symptoms such as sudden fever, chills, conjunctival edema, headache, muscle pain , nausea and vomiting last 4 to 5 days. In the second stage (immunological stage), meningeal irritation, rash, uveitis, muscle aches, etc. are observed, and between 15 and 80% of them present symptoms of aseptic meningitis. There are cases of death from complications such as liver failure, kidney failure, acute respiratory failure, and severe bleeding.

The nephrotic syndrome that initiates fever is divided into 5 stages, showing clinical characteristics. At first, fever, chills, weakness and severe headaches appear, and as a result of fever, hypotension or shock appear at half the frequency. After that, urine, kidney failure, severe abdominal pain, hematopoiesis, and bloody stools do not appear, and after that, kidney function is restored and you urinate several times. At this time, symptoms of dehydration can also accompany. Nephrotic syndrome hemorrhagic fever can be vaccinated. Two basic shots should be given at 1-month intervals and 1 additional shot 12 months later (3 times total), and is best for soldiers and farm workers who have lots of outdoor activities.

When you do outdoor activities, you should wear daily clothes and work clothes separately. Wear clothes like long sleeves, long pants, hat, carpenter, toshi, gloves, socks, boots, etc. so that the ticks do not directly touch the meat, and when working, the sleeves should be tightly closed, and the pants should be tucked into the socks. Using a tick repellent can help.

When doing outdoor activities, don’t remove your clothes or lie down on the grass, and don’t urinate on the grass. It is better to sit on a mat and wash and dry the used mat. After outdoor activities, you should wash your clothes and shower or bathe. You should carefully check for ticks in your hair, around the ears, under the arms, around the waist, behind the knees, and between the legs.

Park Sook-gyeong, chief of the Infectious Disease Control Division of the Korea Centers for Disease Control and Prevention, said, “Please refrain from outdoor activities such as bee grass or graves on the Chuseok holiday and strictly follow prevention rules if unavoidable. ” You should get it, “he said.
