Human rabies symptoms?

summary

Rabies is mainly caused by the transmission of rabies virus to people through animals. Rabies virus contains five proteins: glycoprotein (g), nucleoprotein (n), polymerase (L), phosphoprotein (NS) and matrix (m). The glycoprotein of rabies virus can combine with acetylcholine, which determines the neurophagocytic property of rabies virus. The main source of infection was sick dog, followed by sick cat and sick wolf. After people are bitten by sick animals, the virus in animal saliva enters the human body through the wound and causes diseases. A few patients can also get sick because the conjunctiva is polluted by the saliva of sick animals. Human rabies symptoms? Let's talk about it
