Rabies is an acute infectious disease caused by the rabies virus. It is a human-animal disease, most commonly seen in dogs, wolves, cats and other carnivores, and most people are infected by the bite of a sick animal. How to prevent rabies? 1.Manage the source of infection: Immunize family-raised animals and manage stray animals. 2, bite wound treatment: 20% soapy water or 0.1% Neosporin thoroughly rinse the wound for at least half an hour, trying to remove dog saliva and squeeze out the dirty blood. After thorough cleaning 2% iodine or 75% alcohol wipe the wound, generally without suture dressing the wound in order to drain the blood drainage. If there is anti-rabies immunoglobulin or immune serum, it should be injected at the bottom of the wound and around the local infiltration. 3. Vaccination: For general bites, i.e. mild abrasions, scratches or broken skin licked without bleeding, 2 ml of this vaccine should be injected intramuscularly on days 0, 3, 7, 14 and 28, with the same dosage for children. For severe bites, the vaccine should be given as described above, in addition to a daily dose on the same day to day 6, followed by a dose on days 10, 14, 30, and 90. The vaccine should also be administered on the same day with anti-rabies serum (40 IU/kg body weight) or rabies immunoglobulin (20 IU/kg body weight), infiltrating the bite locally and intramuscularly. In case of combined use of anti-rabies serum or immunoglobulin, two to three additional doses of vaccine must be given after the completion of the full vaccination, i.e., one additional dose on the 15th and 75th day or the 10th, 20th and 90th day after the full vaccination, respectively. The first dose should be doubled in one of the following cases: (1) Those who have received immunoglobulin or antiserum one month before vaccination. (2) Patients with congenital or acquired immunodeficiency. (3) Patients treated with immunosuppressive drugs (including anti-malarial drugs). (4) Elderly and chronically ill patients. (5) Persons who received rabies vaccine 48 hours or more after exposure. (4) Pre-exposure prophylaxis: preventive injection for healthy people who have not been bitten can be given as three injections at 0, 7 and 28 days, with another booster injection every 1 to 3 years.
