Spring is here, and friends are posting photos of spring outings. But then, various skin problems for their children that mothers worried about also emerged. At the junction of winter and spring, the incidence of skin infectious diseases is particularly serious. Among them, the incidence rate of scarlet fever is relatively high for children. Scarlet fever: an acute respiratory infectious disease caused by hemolytic streptococcus infection. Characteristics: fever, angina, diffuse rash all over the body, and obvious desquamation after the rash subsides. Patients and carriers are the main sources of infection, which are spread through air droplets and can also be infected through skin wounds or birth canal. Scarlet fever is a disease that people are generally susceptible to, but the incidence rate is relatively high in children. Among them, the incidence is more frequent in winter and spring. Scarlet fever has an acute onset and high fever, often accompanied by a high fever of around 39°C. The disease is accompanied by throat pain. A rash will appear about 1-2 days after the onset of symptoms, usually starting on the neck and upper chest, and will soon spread to the whole body. The rash usually turns into plaques in about a week and then slowly subsides. The rash of scarlet fever is usually congestive and bright red, with little normal skin visible between the rashes. During the onset of scarlet fever, the pharyngeal area will be red and swollen, and the tonsils will also be inflamed. The tongue will bulge, giving rise to the legendary \”strawberry tongue.\” During the acute period of scarlet fever, you should get more rest. Because it is an upper respiratory tract infection, you must ensure clean oral hygiene to prevent secondary infections. When taking medical medication, antibiotics should be used rationally under the guidance and advice of a doctor. Scarlet fever is mainly caused by bacterial infection. Penicillin is an effective drug to treat this disease. The general treatment course is one week to 10 days in a row. Be sure to stick to the course of treatment, and don’t stop taking antibiotics prematurely when you think your recovery is almost complete or your symptoms have improved. You should know that although the superficial skin condition may have recovered, it does not mean that the bacteria have been \”defeated.\” Because scarlet fever is most afraid of various secondary diseases that are not treated completely, they will become chronic diseases, such as nephritis, rheumatism, toxic myocarditis, etc. Therefore, it is important to complete a course of treatment to reduce the possibility of complications. After you have recovered from scarlet fever for about a month, you still need to go to the hospital for a review to rule out possible complications. Especially in the middle and late stages of the disease, if there is a small amount of urine, you need to seek medical treatment in time to rule out the possibility of nephritis.
