What is the pathology of scarlet fever, the causative agent of scarlet fever is .

Scarlet fever is an acute respiratory infection caused by group A, B(B) hemolytic streptococcus (B) that produce erythrotoxin.

a.The grass green is bright and shouts streptospherous fungi.

Group beta hemolytic streptococcus.

c.Staphylococcus aureus.

d.Streptococcus faecalis.

e.Staphylococcus pust.

Correct answer: B

1. Scarlet fever is an acute respiratory infection caused by group A hemolytic streptococcal infection. From the perspective of pathogens, scarlet fever is caused by group A hemolytic streptococcus, and most of the pathogenic bacteria of purulent tonsillitis are also caused by group A hemolytic streptococcus, and the pathogens of the two are basically the same.

2. The disease is more common in winter and spring, and is more common in school-age and preschool children (4-7 years old), and infants and young children are relatively rare. Scarlet fever is classified as an infectious disease and is managed, but its spread is relatively inwidespread and causes relatively few large-scale epidemics.

3. Most children with scarlet fever have the onset of hyperthermia, the body temperature can reach 39-40, accompanied by headache and sore throat, and the child is mentally weak, which is more serious than the common cold and fever.

The rash can appear on the same day or the next day of fever, and the rash appears very quickly, starting from the back of the ears and the neck, and rapidly spreading to the chest, back, upper limbs, and finally lower limbs within 1 day. However, the rash is more special, showing a "drunken" rash, that is, the child's whole body is flushed as if he has drunk alcohol, but often no obvious rash is visible.

Another typical manifestation of scarlet fever is scaling and peeling after the rash has resolved. The rash generally does not last long and can subside 2-4 days after giving an effective **. Significant desquamation of the trunk** after the rash recedes.

Membranous peeling may be seen on the soles of the palms and feet, and cracked peeling of the nail ends is typical. The peeling lasts for 2-4 weeks and leaves no pigmentation and no scarring.

4 If this problem is seen before the 40s of this century, scarlet fever is a very dangerous infectious disease, and with the development of medical level, the first effect of scarlet fever is generally very good.

From the point of view of pathogens, scarlet fever is caused by group A hemolytic streptococcus, and most of the pathogenic bacteria of purulent tonsillitis are also caused by group A hemolytic streptococcus. So, if you were told that scarlet fever and purulent tonsillitis are cognate diseases, would you be greatly relieved?

Scarlet fever is an acute respiratory infection caused by group A hemolytic streptococcal infection. (1) Tin powder: take a little medicine and blow it into the throat to clear away heat and detoxify, reduce swelling and improve pharynx. (2) Zhuhuang San: blow on the affected area, used when the throat is red, swollen and ulcerated.
