Symptom incubation period of rabies

summary

Incubation period of rabies -- rabies is an acute infectious disease caused by rabies virus. It is common in dogs, wolves, cats and other carnivores. People are often infected by the bite of sick animals. The incubation period of rabies virus infection to clinical symptoms is one of the characteristics of rabies. Most of the cases are within 3 months, 4% - 10% of them are more than half a year, and about 1% of them are more than one year? Let's talk about it

Symptom incubation period of rabies

The prodromal stage of the two types is similar. Most of the patients had low fever, drowsiness, lack of appetite, and a few had nausea, vomiting, headache (mostly in the occipital), back pain and discomfort; They are sensitive to pain, sound, light, wind and other stimuli, and have a sense of throat tightening. The early symptoms of great diagnostic significance are numbness, itching, tingling, insect crawling, ant walking and other sensory abnormalities in the healed wound site and neural pathway, which occur in about 80% of cases. This is caused by the stimulation of neurons, especially sensory neurons, by virus reproduction, which can last for several hours to several days. This period lasted for 1-2 days, rarely more than 4 days.

Manic rabies: most common in China, about 2 / 3 in foreign countries. Patients gradually enter a state of high excitement, which is characterized by extreme terror, a sense of imminent disaster, and very sensitive to underwater sound, light, wind and other stimuli, causing paroxysmal pharyngeal spasm, dyspnea and so on.

It is difficult to distinguish between coma stage and paralysis stage. Spasticity stopped, patients tend to be quiet, fashion can barely drink and swallow, reaction weakened or disappeared, turn to flaccid paralysis, in which limb paralysis is the most common. Ophthalmoplegia, facial paralysis and masticatory paralysis were manifested as strabismus, eye movement disorders, mandibular drop, mouth can not be closed and lack of facial expression. In addition, there are aphasia, hypoesthesia, disappearance of reflex, mydriasis and so on.

matters needing attention

After being bitten or scratched by animals, the wound should be rinsed repeatedly with 20% soapy water immediately. If the wound is deep, a catheter should be put in and the soapy water should be poured continuously to remove the dog's saliva and squeeze out the dirty blood. Generally, the wound is not sutured and bandaged, antibiotics are used when necessary, and tetanus antitoxin is also used when the wound is deep.
