What symptom does child get smallpox?
First, the prodromal period lasts for 3-4 days, the onset of the disease is sudden, there are shivering, high fever, fatigue, photophobia, headache, back and limb pain, high fever can last for 2-5 days. Fever occurred on the 12th day. In the inferior membrane, the inner thigh, armpit and both sides of the abdomen, there can be a transient Mayan like or scarlet fever like, urticaria like bleeding rash, a small number, this is called "prodromal rash", easy to be ignored. Vomiting and spasm were more common in children patients, with severe appearance, painful expression, conjunctival congestion, and sometimes tears. Mild enlargement of liver and spleen.
Second: there is a certain time, location and order of eruption. On the 3rd-4th day of onset, the body temperature dropped rapidly. The rash began in the face, appeared in the forehead, temporal, face and wrist, then rapidly developed to the neck, forearm, hand, upper arm, chest and abdomen, and finally to the lower limbs and sole of the feet. The rash was more and more dense in the head, face and limbs. The first rash was red spot, and soon became a solid papule about 2-4mm in diameter, Deep in the skin. Thick cuticle of the palm and sole, the formation of hard light erythema. On the 6th to 7th day of the disease, the papule turns into herpes, presenting multilocular, protruding around, with hard red halo and concave center, which is called "pox navel". At this time, the mouth, throat and corner of the eye, conjunctiva and other virtual hair miasma. On the 8th to 9th day of the disease, the herpes continued to fill, the content was turbid and turned into pustules. At this time, the body temperature rises again and the poisoning symptoms worsen. If combined with bacterial infection, the symptoms are more severe; They may die of pneumonia, heart failure or peripheral circulation failure. At the same time, the oral and upper respiratory tract mucosa also has mucosal rash. When the mucosal rash turns to herpes stage, the epithelial layer ruptures to form small inflammatory ulcers, resulting in salivation, hoarseness, photophobia, nasal congestion, tears, sore throat, dysphagia and irritable defecation and other symptoms.
Third: scab stage in the course of 11-12 days, pustules gradually dry, forming a thick yellow green scab, consciously itching, body temperature gradually decreased. After 2-4 weeks of illness, he began to get rid of his infatuation, leaving a lifelong depressed scar, especially on his face. After the appearance of smallpox rash on the face of white head, the rash, papule, herpes, blister and scab appear in sequence, usually from eruption to scab, about 8 days. At the same time, the same part of the rash is often the same morphological changes. Sometimes the rash can stop developing at a certain stage, and pustules and scabs may not appear.
matters needing attention
Smallpox is mainly transmitted by inhalation of droplets or direct contact. Smallpox virus adsorbs on the surface of epithelial cells in the upper respiratory tract of susceptible people and invades. It quickly reaches local lymph nodes and tonsils and other lymphoid tissues. After a large number of replication, it enters the blood, forming the first transient viremia. Through blood flow, monocyte macrophages infect the whole body, and continue to replicate and release into the blood, leading to the second viremia. Through blood circulation, the virus spreads more widely to the skin, mucous membrane and internal organs. At this time, the patient developed high fever and general discomfort. After 2 to 3 days of prodromal symptoms, smallpox rash, this time must go to the hospital for treatment.
