For the rabies wound, just start to feel a little red dot, slowly you will see that this little red dot is getting bigger and bigger, and finally it will cover the entire part of your bite, it will become red again. It is swollen and accompanied by the symptoms of pain. As the condition progresses, I feel that my mood is affected, and I become very fearful and uneasy. My throat is not breathing smoothly.
The incubation Period varies, most of them are within 3 months, the length of the incubation period and age (small children), the wound site (early onset of head and face bites), the depth of the wound (short period of deep wounds), the number of invading viruses It is related to factors such as virulence. Others such as incomplete debridement, trauma, cold, overwork, etc., can cause disease to occur in advance. The typical clinical manifestation process can be divided into the following three phases:
Symptoms of rabies wounds
1. Precursor period or invasion period
Before the excitement, most patients have low fever, loss of appetite, nausea, headache, burnout, general discomfort, etc., which resembles a “cold”; then fear is uneasy, sensitive to sound, light, wind, pain, etc., and has a throat Tightness. The more early diagnosis of the symptoms is the abnormality of the wound and its vicinity, which is caused by numbness, itching, pain and ants. This is caused by stimulating neurons during virus reproduction and lasts for 2 to 4 days.
2. Exciting period
The patient gradually entered a state of high excitement, highlighting extreme horror, fear of water, fear of wind, paroxysmal pharyngeal spasm, difficulty breathing, difficulty in urinating and defecation, and sweating. This issue lasts for 1 to 3 days.
The fear of water is a special symptom of rabies. When you see water, drinking water, listening to water, or even drinking water, you can cause severe throat Muscle spasm. Fear of the wind is also one of the common symptoms, breeze or other stimuli such as light, sound, touch, etc., can cause pharyngeal muscle spasm, serious fashion can cause systemic painful convulsions.
When the sputum stops, the patient gradually becomes quiet, but there is a slow sputum, especially in the soft palate. Eye muscles, facial muscles and masticatory muscles can also be affected, manifested as strabismus, eye movement disorders, mandibular fall, mouth can not be closed, face lack of expression, etc., this period lasts 6 to 18 hours.
The overall course of rabies is generally no more than 6 days, and occasionally more than 10 days. In addition, there are also “paralyzed” or “static”, which is also known as the main manifestation, also known as dumb rabies. This type of patient has no excitement and fear of water, but begins with high fever, headache, vomiting, and bite pain. Then there are limb weakness, bloating, ataxia, muscle cramps, incontinence and so on. The disease lasted for 10 days and eventually died of respiratory muscle paralysis and bulbar palsy. Rabies caused by a vampire bat bite often belong to this type.
