[/INST] Hello, Welcome to Chat Doctor, As you were bitten by a stray dog over the calf which has led to bleeding from the site of bite, dog is known to transmit rabies, which is 100 % fatal, but it is 100% preventable by proper and adequate treatment. As there was a bleeding from the site, according WHO categorization it is categorized into Cat III, Which requires following treatment.1. Wash the wound thoroughly with soap and water to wash out the rabies virus if it is present in and around the wound.2. Active immunization with anti rabies vaccine on days 0,3,7,14 and 28.3. Passive immunization with rabies immunoglobulin in and around the wound.4. Inj TT, if you have not received in last five years.5. Oral Tab Augmenting, 625 mg, twice daily for five days. The aforementioned measures will help to prevent development of rabies. Thank you. </s>
